Got my car UpREV tuned ALL STOCK no mods

[hugedude33]

today I got my M45 Uprev tuned at r/t tuning in Lansdale PA. My car is 100% STOCK, all I had done is the Uprev. Im still debating about what catback exhaust to get. When I figure out how to post pics, I will put the chart up with the gains, but until then here's the numbers.

RunFile_001.drf Max Power = 271.29 Max Torque = 289.12

RunFile_005.drf MAx Power = 281.18 Max Torque = 300.40

Gains: 10rwhp & 11rwtq

Fuel: 93 OctaneRun Conditions: 51.53 F, Humidity: 21%

Ok, right out the gate I notice more thrust. My tires was spinning like never before, once they gripped the road, the car was out. The WOT restriction is gone. I notice the gears shift at a much higher rpm. They stay in gear a lot longer. In automatic the car has awesome acceleration with very smooth gear shifting.

I have 5 Maps

Map 1: 93 OctaneMap 2: 91 OctaneMap 3: Valet ModeMap 4: Anti Theft (kill switch)Map 5: Stock

The UpRev Osiris Reflash Stg1 $300Dyno Tuning $175

Total cost with tax was $503

good stuff, how much did they charge you if you dont mind me askn? Also how does the kill switch work?

[hugedude33]

To put the car in Anti Theft mode. you press down and hold the SET/COAST switch on the steering wheel and press the cancel button 4 times. A green set light will flash 4 times on your tach and that will let you know what mode or map your car is in. If you want to put it back in the tuned mode, hold down SET/COAST switch and press cancel botton once. ITS SO EASY A CAVEMAN CAN DO IT!!!

Out here in CA, we don't have readily accessible (that I know of) 93 octane. Is it mandatory you get the 93 octane map? Or can you specify which map(s) you get, and in what order?

How long did the entire process take?

I'm still very, very curious: If you bring this into the dealer in "stock" mode, do they check the ECU for any reason and would the presence of the other maps be an issue?

No, the maps are completely custom, the tech recommend some map options but its completely up to you. Just tell them what you want and order you want the maps in.

The whole process took 2hrs. It only takes 5 mins to reflash the rom. The rest of the time was dyno tuning. To be honest they only did a little over an hour tuning cause im coming back to get an exhaust put on in about another month. Then the car would have to be retuned. He usually tune for about 2hrs (you get charged by the hr for tuning) so he split tuning time in half to save me money. once I get the exhuast he's gonna retune the car for another hr. So at the end of the day, Im payiing the same as if I had everything done at once.

The maps are completey stealth. If the ECU is in stock mode, they wont detect it. Vince at R/T tuning said they've done over 60 G35, 350z, never had a issue about warranty.

What does dyno "tuning" actually do if the UpRev maps set all the parameters for you? I understand the dyno will show the gains. Why so much dyno time? I am considering UpRev at this point.

[tytamto]

Consider a dyno a 'rolling road.' It is the most consistent and safest way to tune a car. Many good tuners will follow a dyno tune (after creating a 98% of the new mapping) with a true road tune... you drive, they fine tune the parameters on their laptops in the passenger seat.

Not sure if UpRev tuners do it the same way, since the car does not have forced induction, it probably requires a lot less 'tuning' and time on the dyno.

On average, it costs around $100 just to get your car strapped onto the dyno... so $175 for a tuning session was not too bad...

Are UpRev tuners able to mess with TCM programming as well? Or is it all ECU?

No TCU control from uprev or any other tuners for that matter - you only get that on domestics since they actually like the aftermarket where as japanese auto manf try and make their ecu's un-hackable due to their strict vehicle, traffic, and emmision laws.

Gotta love the cool weather and good gas! Those are great numbers for a stock car.

What kind of dyno did they use to tune? was it on rollers or did they take the wheels off and bolt it to the hubs?

Wow. I JUST got this email from EIP Racing in Milpitas, CA (copy and pasted):

"is gona be $300.00 for uprev software and $300.00 for dyno tuning"

I pray they were typing that on an iPhone or something. Will take about 3 hours.

According to their marginal webpage, they use something called a Mustang Dynamometer MD-AWD-500.

It was tuned on rollers, DYNOJET

[peter_rabbit]

We really need something or someone here in the midwest that can offer that Uprev tune. I would really like to have that done.

Actually, thats about right. the place I went to charge $175hr. most of the time it take 2hr to really tune it good. they tuned my car for 1hr cause im going back in about a month to have an exhaust put on. at that time they will tune it again for another hour to get it just right. So when it all said and done it gonna be $350 for tunig. With the exhaust added, I should see another 10hp and 10tq. bringing my total gains to 20rwhp and 21rwtq, HOPFULLY!!!!!!

[WirelessAndy]

So lemme see if I understand this.

They upload some maps of your choosing (91 octane, Stock, valet, etc) and hop your car on a dyno.

They watch the plot. Hm, let's tweak this parameter.

Dyno run again. Repeat as necessary.

Sound about right?

[fiveliterbeater]

excellent numbers bud!!!!

glad to hear you like it! get that exhaust ASAP for a more noticeable diffrence!

they did a total of 5 runs on the dyno.

If you look at my first post. My stock numbers was RunFile_001.drf

My tuned numbers was RunFile_005.drf

Nope - they load in the ROM file which turns the stock ECU into a fully customizeble ECU with storage capacity for 5 separate maps that can be tuned individually. Then they strap it onto the dyno and custom tune it to maximum depending on your setup.

The UpRev tune you get with the Osiris Standard is a basic tune, then you use the Cipher software to data log your 0-60 runs, send them to UpRev for 3 eTunes where they look at all your parameters and make changes based on the data file. Not as good as Dyno tuning but way better than just a "chip" that you used to get.

UpRev is a very Unique product with near endless possibilities for engine tuning.

If you want to change Transmission shift pioints and stuff like that UpRev can't do that - but the Transgo shift kit is all you need for your transmission.

Ken, I was looking at the chart and I notice a dip in hp and tq around 5200rpms. The tech said its what you call a butterfly valve and its not much you can do about it. Do you know anything about this.

Yeah - at 5000rpm the power valve in the intake manifold opens effectively reducing the runner length in the intake manifold which is better for high rpm horsepower. The dip is because the split second it opens it causes hella turbulence reducing airflow for 100-200rpms and it takes a little time for the valve timing to catch up to take advantage of the lower restriction airflow after the valve fully opens.

We did a couple runs just to see what would happen if we left it closed or open for the entire dyno pull. Did it just for fun and you can see it really does work.

There's really nothing we can do about the dip, unfortunately we have to live with it.

Can you post the graph?

[EniGmA1987]

I just had a quick thought about this and hopefully I dont sound too stupid...

Can you make one of the tune "profiles" set to have lower HP and torque and get less emissions that way? California has some strict emission laws so it would be incredibly useful to have the performance tunes and then a low emission tune so that when you have to take the car to get smogged you can switch to that and pass easier. Or maybe just turning for less HP and torque wouldnt make a difference on the emissions, maybe the car could be limited to 5k rpms or something so if the engine doesnt run as fast then it wont push out as much exhaust? If the guy starts getting suspicious I can just tell him its a factory governor because its a luxury car not a sports car

You normally keep your stock program as one of the maps so you can always get through smog or take your car into the dealer.

If for some reason your stock program doesn't pass emmisions then you have a problem that needs to be identified and repaired.

there is no reason why you would need a lower hp tune - that's just nonsense

[hugedude33]

lower hp tune......LMFAO. Now thats funny.

Well, they have a valet map which doesn't allow the rmps to go over 3200 and your max speed is 30mph. You can floor it and it will only go 30mph.

[hugedude33]

Hey Ken, what exhaust would you recommend. I dont want it to be too much louder than the factory. I like the low growl of the factory exhaust but in order to get max performance out of my car I need to change the exhaust. I spoke to the tech about people experiencing lower power with the injen CAI. He said he would build a hood around the filter that would create like vortex and the air would be sucked in 10 times better. These guys build race cars everyday, thats all they do. They might know what they're talkin about

[dvan]

Man ...i want to get this UpRev tune so bad! I just need to find a way to convince the ol ball-n-chain lol

[Backdoc7]

excellent numbers bud!!!!

glad to hear you like it! get that exhaust ASAP for a more noticeable diffrence!

5L, did you get your car UpRev'd? I believe you were talking about it..

HugeDude33, good numbers! Sounds like it's as much the "tuning" or opening up the ECU as it is the 11 hp your feeling huh? does that question make sense?

#1 Ditch all the factory stuff between the rear mufflers and the headers. That is the main restriction in your exhaust. Surprisingly the rear mufflers on the M45 are a chambered low restriction muffler and are nearly straight through design.

#2 Add in Magnaflow Metallic Cats just after the rear O2 Sensors. This will keep you legal in 49 states to pass a visual.

#3 After the MF Cats install some stainless steel braided flex pipes 6-8 inches long should be enough.

#4 Add in a Magnalflow True X pipe or similar or use the Magnaflow Muffler that has an internal X pipe design.

#5 After the X pipe, add in a pair of 4" round mufflers @ 22" long

#6 After the round mufflers - conect the dots back to the stock mufflers. If you want a little more aggresive sound and look - install magnaflow mufflers offset in center out and your choice of tips.

Maximum size of 2.5" on all the pipe. 2.25" would be good enough and tighten it up a little in the sound dept

[Q45tech]

Simple to measure and graph exhaust system or cat restriction vs rpm and the effect on power reduction. Each 1.0 psi represents ~ 2 HP [1.8>2.2] lost. Also graph noise level vs back pressure.

You will not see very much restriction until 4,000 rpm> 6900 rpm.

Nissan like all Japanese typical trade 4-5 HP for reduce noise to comply with standards.

5L, did you get your car UpRev'd? I believe you were talking about it..

i get my taxes back on the 12th and my car is getting UpRev'd shortly after. trust me, everyone is going to know when i do mine : )

[EniGmA1987]

Let me know where you take your car for the tuning fiveliterbeater, I live pretty close so I will probably go there as well.

[fiveliterbeater]

im going to Specialty Z in Chattsworth. you're more than welcome to meet me there (or follow).
