Good new info guys! So I have been using wstar throttle map for almost a year now. My only issue with Uprev is the inconsistency of how the tune stays there without the stock ECU inhibiting the Uprev full potential. One day car pulls harder from dead stop, another day it just flat out slow. This happened in any season of the year.

When my car was Etuned by Seymore, it was in the middle of hot summer, then found out about wstart throttle map at the start of fall and used it until now. With the change of season here in the midwest, it causes my original tuned A/F fuel ratio to get leaner (winter) , so I richen it a bit. Power was good, but still one day it lags one day it is peppy. Now comes spring season , and temp ranges from 40 to 70 F , so I logged some Cipher 0 to 60 run and still the car is a bit lean at 13.8:1 on WOT. The same MAP was dialed in at 12.8-12.9:1 on WOT summer time. So I asked Seymore recently to richen the car more. Now the car seems to pull harder just buy adding more fuel at 12:8 -12.9:1 and still using wstar throttle map. For a week now the tune is very consistent. It does not run flat in torque which start low 2K RPM and pulling harder at start top of 2k and above. Temp here is up and down from the range of 40 to 75 F . I wonder if the issue is UPREV not totally taking over the ECU parameters that Uprev already broke into?

As for Wstar throttle MAP, do you guys noticed if there is any throttle restriction from below 15MPH ? just curious? Right now throttle appears responsive at less than 1/4 pedal push.
I do not track the car (I have a 2008 EX35 crossover VQ35HR 5 Speed A/T ) , but I would like to have a touchy throttle pedal starts exactly at 2K RPM not 2.3K, but as wstar title of the thread goes, it says SMoooooth..... =) I guess I need to start a new thread title Uprev Touchy Pedal. =)

Jrb55gh, how do you like the ecutek etuned? I wonder if wstar throttle MAP can still be tuned better, due to dip in some RPM points per your observation?

Also, does anyone has an idea how to work on the Torque management table? I would like to see some hex data of your torque management table. So when the tranny slips on specific RPM or gears, i have to increase the number on that specific cell on the torque table? Pls. Clarify. Thanks!
