M45 ECU Programmer??

[M4T5]

Hey guys, I'm new. I have never owned a Nissan or Infiniti product before.Anyways, I have a 2007 Infiniti M45 (Base, Not sport).I have always loved the benefits of the aftermarket world when it comes to performance increases.What I'm noticing is, there are no go fast goodies for this car! The web comes up with all of the same thing...maybe I'm missing the hidden sites??I find, brake, suspension, air filter, and a Jet chip upgrade is all. Is that really all that is out there for this car?? I wanted to get a ECU programmer to increase engine power and fuel economy. I will not be removing the computer from my car and send it off to someone. At least that is what Jet requires. Is there a hand held product out there for my car?What will make my M45 a bit faster without breaking the bank?Man, this sure isnt like GM and Ford that I'm used to. There are unlimited amounts of aftermarket parts for their vehicles.... Any help would be appreciated.

Thanks,

J

Although a lot of Japanese cars have TONS of aftermarket parts, the M is not one of them. They simply didn't sell enough of the cars to warrant R&D to create products for our cars. And to be frank, most luxury car owners won't modify their cars, again eliminating the need. I do miss buying inexpensive pick-me-ups for my car, but I love my car enough stock to let it slide.

Wow, that is really sad to hear. I wonder if there are a few local tuners that can tune the car in person then.I haven't really thought of that, but seems like it may be my only choice.I've had many of my Camaros and Mustangs tuned that way in the past, but never an import car.That may be my only answer unless someone here knows more than what we already know.

What are you looking to do? These motors don't have much left in them as is. You would most likely hurt economy rather than make any significant hp/tq gain.

Just put money into making sure the engine runs right and it will give you many years of scaring the crap out of other would be "performance cars".

I'm looking for more power than economy. This wouldn't be my first attempt with computer tuning for vehicles (custom or hand held). I've never had a tune that didn't increase power and fuel economy at the same time.I've never seen a OEM engine and computer configuration that didn't have room to spare. These engines more than likely have quite a bit or room for improvement.As for my care with my vehicles... I take and treat them to the very best possible, but I'm a power enthusiast. I want more power than stock. If it's available, I'm going to give it a try.If it cannot be reliable with a tune, then.... I guess the American made engines are on a more solid platform. That's what I'm used to.This is my wife's car, but I want it to be faster. She can own foreign, but I'll stick to the real American V8 MUSCLE. That is as soon as the 2nd year of the new Camaro becomes available. As I never buy the first year out of a new platformed vehicle. Until then, this car will have to try and impress me. Though, when the Camaro gets in my hands, that Infiniti will not be able to touch it.Not trying to burn the M45 at all. The car is a blast to drive. Either way, the facts are the facts when you try to compare Foreign power to American power.

really......can you give a specific example???

I've never seen a OEM engine and computer configuration that didn't have room to spare. These engines more than likely have quite a bit or room for improvement.

4.5 Liters equals about 273 cubic inches. Your getting 340 hp outa 273 inches. No, they really dont have 'quite a bit of room". You need to spend some time reading a tech sheet on the engine. hop over to the Q45 forum.every newbee wants all the bolt ons and come to realize that the 4.5 is infact a very fine tuned engine and is at the cutting edge.

As for my care with my vehicles... I take and treat them to the very best possible, but I'm a power enthusiast. I want more power than stock. If it's available, I'm going to give it a try.If it cannot be reliable with a tune, then.... I guess the American made engines are on a more solid platform.

No, american engines do not have a 'more solid platform'. the tolerances are not as tight. they build with tons of room for improvemnt because they dont want to push to the edge of tolarence.

That's what I'm used to.This is my wife's car, but I want it to be faster. She can own foreign, but I'll stick to the real American V8 MUSCLE.

example 2008 pontiac G8 :The base is packed with a 256-horsepower, 3.6-liter V-6 engine, while the GT gets a 361-horsepower, 6.0-liter V-8 engine.you have to askyourself why a 6 liter (33% bigger) gets only 6% better hp????

That is as soon as the 2nd year of the new Camaro becomes available. As I never buy the first year out of a new platformed vehicle. Until then, this car will have to try and impress me. Though, when the Camaro gets in my hands,

2009 camaro ss w/6.2L 422hp......wow......but that's only 68hp per literthe M45 has 75.5hp per liter.

plenty of room to tweak the chevy....it's underdeveloped even though it makes 60 more hp than the pontiac.that Infiniti will not be able to touch it.

why dont you compare your camaro to a GTR? 3.8 liter 480 hp or 126hp per liter. you need a pretty "solid platform" to make that happen from the factory V6.

The M45 is a 4 door sedan.the camaro is a 2 door sport car.what's to compare?

Not trying to burn the M45 at all. The car is a blast to drive. Either way, the facts are the facts when you try to compare Foreign power to American

what facts are you talking about?????

I'm all about american muscle. My first car was a 66 mustang. One of my previuos rides was a linclon MarkVII LSC w/ the HO 5 liter. a very Nice Ride.But I also am sold on the Infiniti products and particulaly the 4.5 engine.power.

I hope that GTR is naturally aspirated! Compare apples to apples! I can buy a Camaro and purchase a turbo or supercharger and take out that GTR without a sweat. Then have plenty of extra money left over to do more mods.How much is a GTR???? Yeah, too much!The GTR is nice....don't get me wrong. Though your comparing power outputs of a turbo engine against a NA engine. Not a good comparison.You can look it at however you want, but the G8 will outperform the M45! In whatever maneuver you want in aesthetics. In the luxury and styling department.... yep, the G8 definitely falls short, but not on power and under $30K. You cant beat that deal. Though since I didn't like the exterior looks and lack of interior features, I purchased a M45. The G8 is a 6.0L and gets better fuel economy than the 4.5L 273 ci engine. Explain why that is? Your talking about HP per liter??? Hell we'll just place a better set of heads or a better cam in that LS3 engine and really turn up the power. Also, my previous LS2 engine received a 52 hp increase at the rear wheels from just a tune alone, and still had a safety buffer in my tuning. Don't compare a GTR (turbo equipped) to a naturally aspirated engine. Show me a foreign V8 engine that is naturally aspirated that outperforms an equivalent sized American V8 engine. That outperforms it and gets the same or better fuel economy. Your not going to find one!

You know what, all I wanted was a hand held programmer or computer software to tune my M45 guys. I guess I will have to make due with a stock car....

Your going to need a custom tune from a performance shop. You might be able to squeeze and additional 50 horses with a free flowing exhaust, intake and and a tune to get the air fuel mixture just right, or get it tuned to 101 octane.

The VK45 is pretty much maxed out. You want more HP? Turbo that *****. There is room underneath where the exhaust is for a couple of small turbos.

[mcrews]

I hope that GTR is naturally aspirated! Compare apples to apples!

do you think before you write??????

you want to compare a camaro to an M45......what am I missing.....you think those are the same?????????????

the point of showing the GTR had to do with your coment on'solid platforms'If camero is 'hot" why cant they pull more that 68hp out of a liter?guess those factory engineers are .........????all of my comparisions are factory to factory.

The G8 is a 6.0L and gets better fuel economy than the 4.5L 273 ci engine. Explain why that is?

hummm....wieght and gearing?????I just drove to Salt Lake city from sacramento CA in my 02 Q45, and drove around fro 5 day. I got 24.3 mpg round trip.

well for starters, bmw 4.8liter get 360 hp. I know, it's not the same size as your big v8 6L, but you asked. oh....a smaller size gets better hp. I know that somehow you'll claim that's not fair

Hell we'll just place a better set of heads or a better cam in that LS3 engine and really turn up the power.

back to "apples and oranges" you keep wanting to bolt on stuff to your american V8 to get a better result than a stock foriegn V8......

but if that's how you want to play......

audi 4.2L 450hp 107hp/l from factoryaudi 3.2 255 79bmw 5.o 507 100bmw 4.0 309 77corvette zr1 6.2 620 100 (threw this in for grins) see all of the foregn engines are in sedanslexus 4.6 386 83.9mercedes 6.3 525 83mercedes 2.8 v6 231 82.3mercedes 5.5 360 65nissan 3.5 290 82

well.....Show me a foreign V8 engine that is naturally aspirated that outperforms an equivalent sized American V8 engine. That outperforms it and gets the same or better fuel economy. Your not going to find one!

ok just did. I probably could have found more.....

these are all normally assperated engines. all but one performs better than the LS 6L buit for the camaro. and the one that dosent missed by only 3 hp!!!!!buy iy isnt about hp. it's about weight to hp and all the forgien makes get more out of every pound than american cars

when you make a statement like this "then.... I guess the American made engines are on a more solid platform. That's what I'm used to.This is my wife's car, but I want it to be faster. She can own foreign, but I'll stick to the real American V8 MUSCLE. "

your going to get corrected.hey we all would like an instant 50hp. but just because we can't find it does mean we start doggin the car.what most of us have come to appreciate is in fact that the 4.5 is a very finely tuned engine...from the front of the air intake back to the exhuast tips. It is a very complete package.

No, your right Mark. I flew a bit off the handle a bit. Basically it comes down to this, your not going to get more product for the money spent in a foreign car vs. American. You really cannot beat the bang for the buck....and use that left over money to treat yourself to a few mods. You have to agree on that. I think the American Auto manufacturers could match foreign car manufacturers quality with a lot of refinement in their organizations.They need to start with lowering the wages of the assembly line workers. Which if I'm not mistaken they are already stating they will be cutting their wages in half.Either way, we need our auto manufacturers to survive this crisis. Liking their vehicles or not. The US doesn't make horrible vehicles, just not refined vehicles. I guess they could put more technology and styling in their vehicles if you matched the MSRP prices of the foreign vehicles.What do you think about the new Corvette Z06 in comparison? That's probably one of the best US vehicles to buy when it comes to styling, quality, ride, and power for the money..IMO. So I will apologize for my rant. I still would like a tuned M45. I never said I disliked my M45 either. Just wished it was a little more powerfully tuned.

If I could get an additional 45 RWHP from an intake, exhaust, and a tune while running on 93 oct fuel I would be content.Though I don't want to make it sound awful with an exhaust upgrade. Just a little lower toned grunt would be fine and a quiet cabin under normal driving conditions.Though, I wouldn't know where or who to go to for a custom tune for this car. I know there is more than likely a reputable tuner here around the Houston area, but who would have that info?A turbo would be nice, but I definitely would want it to be in a quality kit form that is tested and proven reliable. No fabbed parts for this car will be in order.I guess unless there is a demand for a turbo for this car, it will not be produced.I would have thought there would be a demand for one...or two! I kind of wish I would have purchased a M35 and used the extra money saved for some performance parts. Oh well, it's still pretty fast.

If anyone knows where I could get a custom tune here in or around the Houston area please let me know.Thanks,

I hate to break it to you bud, there aint much left in these engines. There is soo little room for fuel curve and timing adjustments that is would be pointless. Me thinks you should of bought a sports car. Most of us seem to be content with having a fairly peppy luxury car from the J.A. Pan company.

If you feel the need to wear the engine/transmission down faster, more power to you.

I wish you the best in your quest.

[mcrews]

hey M4T5,no harm no foul.

And we do agree on the whole american thing.It is nice to buy a factory ride and start to add-on stuff!

And, yeah, a 35 would have given you a LOT of options!!!!

But cruise the site for a while. also the Q45 site for the 02 and up.we all have the same motor. You'll find that alot of the everyday brands of bolton just really dont do much....if anything.

I removed m rear muffler and went w/ straight pipes. mainly I got about 2 mpg better. cant really say on the hp. and the growl as very acceptable.I have always wondered why the M45 has 2 suitcase mufflers and the Q45 has only 1? we both come uot of the cats into one center pipe that splits!!!I know having 2 mufflers is more 'hotrod' than 1 and the M is the hotrod and the Q is the lux.

yeah,that vette is sweet. cant imagine what the weight to hp ratio must be???!!!!

have a great day and happy new year

mark

ps. remebeer when some one says 12-15 more hp, 95% of that gain comes at the top of the curve. Howoften are your cruising at 5-6k rpm?

I seriously doubt 40-50 HP will put the engine and transmission in harms way. You would have to seriously punish your M consistently to accomplish this. I'm not one of those people. I just like that occasional burst of additional power when I'm feeling froggy. If "most" of us were all so content, then the aftermarket world would not exist. It's there for our disposal. You may like only driving a factory car in the exact way the manufacturer delivered it to you. I like to drive an upgraded factory car.Thanks for wishing me the best in my quest!

[notacarlo]

Meaning we are content with our M's and the poor aftermarket.Sure, we'd take advantage of it if it was there.

I'm not faulting you for your desire to add power, but in your extensive American V8 travels you must understand what and extra 40-50 hp can do to sub-standard hard parts.

I fried the clutches in my 200R4 by adding an alky kit...within the first 6 weeks back in the day. More power equals heavier foot...period. Don't deny it, we all have that sickness.

[notacarlo]

Honestly, I am not trying to pester you here.

Not many people buying parts for their Ferrari's these days. Gets kinda boring.

[RAGTPZ]

I will NEVER own an American made vehicle EVER again. I just want to throw that out there. I am not trying to put anyone or anything down, I am just saying that I have owned more than my fair share of American cars and EVERY single one of them was a piece of garbage.

That is what you are paying for when you buy a car like Infiniti, Lexus, BMW, Audi, etc. and hence why I bought this car. If I really want power serious power, I am not going to look at any particular sedan for that. I will go out and get something that will make better use of that power and be more fun to drive, hence see my sig.

HNY everyone!

[saeedakobiakov]

how about new ZO6?

[M4T5]

how about new ZO6?

We already came to agreement that the Z06 probably has the only American made motor that can live up to the foreign ones in comparison.
