After reading the thread most people here don't know how to use Uprev and how are AFR's work,the correction factor is between 75%-125% with 100% being on the money if the ECU moves the AFR toward the 75% it is taking away fuel and toward 125% it is adding so the reason for tuning is to get the car to run as close to 100% as possible so the ECU has full range to adjust rich or lean depending on the information it receives from all the sensors.
If the ECU is not adjusted properly let say it at a giving RPM and load it is running 125% it is maxed out and can not add anymore fuel this is why it is VERY IMPORTANT to get it to 100% so it can do it job. You guys get the point.

I'm kinda clueless when it comes to gettin' an UpRev tune ...
I don't have alot of mods on my Sport Package ( K&N Typhoon C.A.I., Berk Hi Flow CATS and OEM NISMO exhaust ) Would I need a tune and would it be worth it for this little bit of moddin' and if I did would it void the warrenty ... I've read that yes and no that it would so I'm like I have the 7 year 100,000 mile extended and would hate to **** that up Thanks ! |

Your mods aren't a "little", the general consensus on the forum is intake and exhaust (more your HFCs), you need a tune. As for the warranty, 70%~ of this forum would say that if you have any issues with your car that you can revert your tune and Nissan won't be any the wiser. I completely disagree, and I think I've dealt with corporate more than anyone else, and I've asked about all these things as well, so do it at your own risk. There ARE several advantages with only few disadvantages (cost, warranty loss) All I'm trying to say is that don't believe all the "wow, my car dyno'd 315WHP, and I gained 30WHP because of the tune!" No, bullshít, you didn't let the ECU recalibrate and learn over time, you did a baseline, added parts, dyno'd again, and then tuned it, ECU still thinks it has stock boxes, low flow cats, and a 1" diameter exhaust. That's why the gains were so high. Tuning levels out the A/F ratio and such. But if the car couldn't tune itself, you'd get a CEL, and if you do have catastrophic failure, hell with it, revert to stock, and they almost can't know you ever modded your car, lol

264 base line with full bolt on's 304 and one at 309 SAE converting to actual power it made 322. ( but that's not the true # ) 304 is.
its a 7 AT and i trap at 114.7 12.342 in the 1/4 mile all motor . to run those speed and trap it would have to make 342 rwhp for a 3355 lb car, i dynoed on a dyno jet with my home made Cobb tune. I now have uprev and still trying to figure it out. Z
