Robert's M45 Uprev tune (NJ)

[06M4.5]

I was able to go with my friend Robert to get his M45 tuned with Uprev today.
He was able to find an Uprev tuner in NJ (rt. 35 south) that was about 30mins from my house.

JDSMotoring
12 Industrial Drive
Old Bridge, NJ 07735
732-231-7750

The dyno they use is a Dynotech made by Dyno Dynamics. It's the type of dyno that will give you real numbers, not over inflated numbers that most of the time add 15 to 20% more power. They don't have a dyno for all-wheel drive cars.

Robert's M45 had the Megan Racing mid-pipe with axle back exhaust and an aftermarket air-filter kit. He was running with his oem 19" sport wheels.

It was a nice day and it was about 66 degrees. Dyno with tune took almost 2hrs. with well over 12 runs.

We started with a run that showed 235hp (car was running very lean) to the rear wheels and at the end we got an extra 35hp with 30torq. AFR 11.9

He also got 5 maps:

Eng kill
tune with 93 gas, sport
tune with 89 gas, econo
stock
valet mode, only up to 10mph

Top end limiter was removed (from factory it was set at 144mph)
lower delay (WOT gas pedal) up to 20mph removed
timing was advanced

Paperwork will be sent to me thru e-mail as Robert was running late for his 2nd job.

As the car came out of the shop the tuner took Robert & I for a test drive (I sat in the back) and as soon as he hit the gas pedal for the first time we all felt the new found power. It just pinned me to the seat, the difference is really big. The look on Robert's face was priceless, grin was ear to ear. The car now pulls from bottom to top, it pulls even harder when the car reaches 4k rpm.

We were all pleased with the results, the car just pulls so much harder now even at WOT at over 100mph. Breaking rear tire is a pc of cake now.

The price for the Uprev with tunes and all dyno runs was $600

I just have to get better so I can get my car done





I hope this info helps for those that are looking to get the Uprev in the future. It's all about the tunner.

Nice gains, any dyno pics also what kind of air filter kit?

[robert_4.5_S]

Great write up Freddie:), thanks for coming with me to the shop. The car runs much better i can feel those 35 HP when driving in sport mode.

Nice gains, any dyno pics also what kind of air filter kit?

Here is one pic not a good quality but this is the only one i got

but only 235 hp to the wheel??

[cruzad3r]

Great price and result. If only they can do AWD i would drive down and get tune.

Comparing his price and results to the tuner in danbury ct, it's definitely a good deal.

Good stuff Freddie

[06M4.5]

Mex he has the R2C intake kit.

As you can see by the pic that Robert posted the dyno is only for 2 wheels.

I heard good thing about RT Tuning too but you would have to call to see if they have an all-wheel drive dyno

yea we started with 235hp

Because of the so many different dyno's with lower or higher numbers there is only 1 magic number that matters. That number is the difference from start to finish. Robert's magic numbers are 35/30

Just to give you an idea, lets say I take my car tomorrow and start with only 200hp. What matters is how much more am I leaving with (10, 20 hpw???) Also these numbers are to the rear wheels, not what the motor has or even to the crank. I was told by Jas the tuner that our trans are the biggest hp robber and 2nd would be our exhaust system.

So I asked what would be the gains on a M45 with berk HFC's with a new 2.5" y-pipe? He said normal gain would be 10hp but it can go as high as 15hp. The question now is would it be worth $1,000 for a new custom y-pipe & Berks HFC for only 15hp tops?????

No wonder my 35 is more fun to drive!
lol, the dyno correction factor could be off... the only value you really need to be concerned with is the delta between the before and after.
There are too many variables to consider when looking at the actual hp numbers. With a baby on the way and fixing up the nursery, looks like my UpRev is delayed for a while.

[mexillis]

but only 235 hp to the wheel??

just so you know hills has an increase to match dynojet numbers so if you take away about 10-15% give or take your numbers would be about the same.

IMO the 1/4 mile time difference is what matters most. Dyno numbers are just numbers to show.

Do you have any dyno sheets to show Robert?

Freedie idk how much it is up in NJ but I hope a custom Y pipe and HFC wouldnt be a grand, as for the cost being worth the extra 10-15 you have to consider how much money it takes to go .1 faster isnt cheap lol especially for our cars with not many mods to choose from. Im still hesitant on the R2C intake and the Injen CAI but have thought about getting one. I mean more air in should always benifit the cars performance but then when people have done better without its hard to pick which route to go. Plus I would need a retune after that which is hard to justify the cost of those combined for like you said 10-15hp extra.

[06M4.5]

Mex you know I was looking in to getting this done to my car for a while now but the money to hp sometimes makes you think alittle harder if it's worth it. Even more when in the last 2yrs I have only driven my M45 3,500k miles.

I was told the Berk's HFC are the best for our cars and they run about $500 + shipping for the set. Now here NJ everything is top dollar, installing the HFC and getting a custom 2.5" y-pipe in SS runs about $400+ tax

After paying for everything I was looking at just about $1,000


Robert's dyno sheet will be e-mailed to me soon, as I didn't see a printer at the shop (maybe broken) but Jas told me he has everything saved in the laptop

[mexillis]

Just get the custom y pipe and keep your oem cats for inspections, buy some air fresheners and call it a day.

[06M4.5]

new power would come from replacing the oem cats. I was told that the Berk HFC's will flow twice as more than oem cats. 2.5" Pipe gain will be small.

And yes airfreshners will be needed or keep window closed

most in the racing scene are using test pipe but are having problems with cel lights on dash.

[mexillis]

I mean remove the cats and make a big y pipe. Then keep your oem stuff on the side.

Hey there.. nice write up Freddie did not even know about this place and I live about five mins away from it.. thanks a lot now I know where to go when I1m ready for uprev.

Robert: nice gains next time if you're around NJ let me know we could meet up ..

Thanks Partysan7

I also have a friend around the area which owns F1 Motoring, we stopped for a few seconds that day.

Nice little bit of pickup you got there Robert... and good write up Freddie.

Thanks. It is a nice little pickup of power car runs really great in sport mode. Im really enjoying it

Hey Freddie...I think if you start by swapping out the OEM ypipe and having one customized 2.5" whether SS or regular piping you will DEFINITELY feel the difference...your exhaust will flow a lot better and you will gain HP/TQ. I've done many experiments with different ypipes.

Stock ypipe: good for keeping sound manageable but flow is 'restrictive'

MotorDyne xyz (ypipe) is by far the best mod I added to the exhaust system -- although made for the VQ35 motor, if someone where to follow the design flow and customize their own it'll be very beneficial to both V8 and V6 motors. It is the flow from the Cats to the mid pipes and so on is what really improves the performance. If you need more, then get a set of used Berks HFC's

I spent less than $300 for my BERKS (got them used from a G35 owner), my MD xyz pipe I got new for approx $400 shipped...

when you get tuned.....YES, you will be happy

As you know how my mods went and my overall HP/TQ gain for my V6....driving has always been a joy....

CPJ LB what is the diff from the xyz y-pipe to the Megan Racing? because looking at pics of both of them the Megan looks to have straighter pipes (less curves) which in turns looks to have better flows.

As per the Berk's HFC's I don't know if they bolt up to the M45 and then a new custom y-pipe will have to be made for the M45

without having any parts on hand to see how everything would go together in my mind I think this might work:

take the M45 y-pipe which are part of the cats out (pipe & cats 1pc unit).

1st- the question is will the berk's cats bolt up to the M45? and if they do which one? 350z, g35 or g37 and what year?

2nd- we all know that the Megan Racing will bolt up to the cats but which one? 350z, g35 or g37 and what year?

WARNING: The Megan Racing y-pipe for the M35 will be short of about 6 to 12" when installed on a M45

4th- A custom pc of pipe (extension) will have to be made to take up the misssing space between the mid-pipe and y-pipe

This is the only way that I can see of keeping the cost down. If everything bolts up the only custom part we need is the extension

tell me what you guys think of this

PS please post only facts so that we may be able to come up with a plan of having a y-pipe/hfc for the M45 at an affordable price.

[CPJ LB]

^ Freddie, the Megan Ypipe's shape is really a "Y" shape which, to me, does not maximize flow from the cats. whereas the MD xyz pipe has more of a "V" shape that allows a smoother flow from the cats and uses a better merge point.

From my experiments, the OEM Y pipe is thinner in diameter. The Megan Ypipe has a larger diameter from the inlets (2.5") and the outlet is 3". The Megan ypipe had a better flow than that of the OEM, but did not come close to the flow of the MD xyz pipe.

Unfortunately I do not have first hand experience regarding the M45 cats/ypipe. I know our newest member Seymore4 has plenty of experience with the G35's and now has an M45, so it's possible he may be able to give some insight on the exhaust set up on the M45 (Cats and Ypipe).

[06M4.5]

I'll wait to hear what Seymore4 has to say about his M45

[seymore4]

I can't wait to see what I have to say about my M45 too... problem with automotive work... you've got cheap, quick, and quality, and can only have 2 :/ This pic was from last Thursday, word was I'd have her back this week... man I'm dying here


Per a conversation I had with one of the guys at Stillen the Y-pipe isn't a restriction on the M45 exhaust until you remove the cats so until there's a viable option for LTH's I'm probably going to leave em alone. I'm in the NW too so I've got a solid 6 months of rain ahead of me... lol

I'm also 99% sure none of the VQ stuff (M35) will bolt up without modification either. If someone wanted to get creative they could cut the cats off the OEM header and weld a cheap magnaflow HFC on there.. should make some pretty decent gains

[06M4.5]

I was able to take a good look at the M45 y-pipe today

Not only is the y-pipe small it's even smaller in some sections, the part next to the flex pipe is a joke. I think the smallest part on the flex pipe is smaller than 2" What was nissan thinking

YOU HAVE TO TAKE A LOOK FOR YOURSELF TO UNDERSTAND WHAT i'M SAYING

I was also able to hear and smell 2 350z that had aftermarket exhaust and test pipe. the sound was too loud for a luxury car like the M and the smell was just toooo much. Not willing to have my car sound or smell like that. Our V8 will smell even more.

So after talking to a fabricator in order to keep the rasp & smell to a minimum and not have to deal with dash lights (cel lights) it's best for me to keep my oem cats.

I would have to cut at the end of both oem cats and add 2.5" pipe to the end of the oem cats all the way to the Megan Racing mid-pipe.

In other words replace the oem y-piping with 2.5" piping while keeping the oem cats in there same location as mounted.

This my not give me full power like running test pipes but replacing just the y-piping will help alot and will avoid having the rest of the problems (dash light, really bad smell & loud rasp sound).

I'll be trying to stop at another shop tomorrow to see how much it will cost me because the shop I went to today only have parts up to 2". All other parts need to be ordered

I would like to get this done soon so I can get my car Uprev'd.

[Partysan7]

Thanks Philip. As soon as Freddie gets better we can meet up in NJ before cold weather comes in. Just to talk or ride together maybe other members will join.

Sounds like a good idea .. maybe we can visit Freddie see how hes doin' and while at J.city get some of that chilli

Is it possible to have only the uprev flash without dyno tuning ?

[seymore4]

Is it possible to have only the uprev flash without dyno tuning ?

Yes, most people actually do it that way. Since 04 all the cars have come with built-in wideband O2 sensors so you can datalog all the necessary engine parameters to tune it with the uprev cable, and then have a tuner make adjustments to your tune based on those datalogs. It also doubles as an OBD2 scanner/ code reader as well.

PM me if you have any specific questions about it or are interested and want to save some money

[06M4.5]

Well I was able to get my y-pipe done today, I got it made with keeping my oem cat's. Now I have 2.5" from cat's to mufflers.

Here ia a pic of the crappy oem y-pipe cut off from the cats:



the pipe is pinched at 6 different spots, each spot is less than 2"

It would be really cool if we could get a dyno comparison of the 2 y pipes
