i jus saw this thread and i responded
u gonna give me **** for responding with a question???

 

Hopefully l'll be able to answer your question after Saturday!

 

Lol! x2

 

I have it, i have an all motor map and a map for my n2o. I gained 30whp from just him playing with the motor map on the 3rd pull over @ Japtrix.

 

thanks for the info........and for RTIID22 let me know after saturday.

 

So Any Tuners Doing This In SOCAL?

 

Off the top of my head...Church Automotive and GTM

 

Are YOu GOnna Switch from your Techno to the Uprev?











(p.s.i guess we both are late nighters huh! lol)

 

Nah, I was goign to at a point, but only cause i wanted a nitrous map and i am over that so no point. Plus I believe that if you just want an NA tune technosquare will get you more power and better reponse than UPrev. I would only go to uprev because of the ablility to have 5 maps on the stock ecu. Which isnt' necessary unles you have nitrous and need a map for that or your turbo/super.

PS: I just came back from a G meet and it was really really fun. I was the only Z their so I was representing for the community And becasue i went i completly ****ed myself over and I will proabbly stay up till 4 am doing work

 

Damn...... lol

You Should Have let me know i would have'd rolled with you!

Next Time.....Next Time

 

Yea definetly...I'll hit you up for the next one in either 2 or 4 weeks

 

I have uprev, I like have the launch control, and knowing that when I go boosted or Nitrous all I have to do is pay 350 car goes on the dyno and after leaving the dyno it will still run like its from the factory. The car runs like a champ and the power is full through and not just falling on its face. I only received a 2 hp gain with nismo exhaust but that is just because Nissan has tuned our cars pretty flawless and that my tune hasn't been thrown to out of whack with my minor bolt on. Also We didn't baseline the car with stock exhaust then with the nismo s-tune.

 

UPREV will out perform most other tunes because it has things that they don't. One example is it has cam timing adjustment which the others do not.

My car gained a good amount for just a stock car. 5 hp throughout the powerband, and 8-10 hp up top. Now I have HFC and going tomorrow for a retune/adjustment since now my A/F is off a bit.

 

Ehh.. went to Japtrix/HP Logic today and got uprev.. few problems, I'm not really impressed.. kinda disappointed, hopefully everything would be resolved on Monday.

Well, I got there at 11 and tuning started at noon.

First the car was giving out a CEL U1000 and the car also had some launch control setting which made it lag a **** load below 30mph..

Then the tuner came up with that Uprev hasn't made a software for my ECU because I have the latest ECU for the 08 Zs.. I bought mine on the end of March 2008 so I dunno.. So he installed the software made for an older ECU for 08 and the lag went away but I can't switch maps and my cruise control doesn't work!! By this time it was 4:30 and he said there's nothing he cold do until Monday.. lets see what happens..

Dyno says I gained 5hp throughout the entire power band but I feel my car the same, and if wheel spin says anything than it's actually slower? Cuz before my car would burn rubber throughout 1st gear from 4k+ and now it just wheel churps.. so yeah.. Don't have any figures at hand.

I came in a too lean AFR 13 flat till 6800rpm then it drops to 12, he richen it up to 12.8/7 and leaned 13 after 6900rpm to redline.

 

Sounds to me your Tuner needs to call UPREV next time and get advice. Improper tuning can cause many problems.

 

I agree.. he tried calling but I think they were closed cuz no one answered the phone/text/emails..
