It was eager to rev and felt like it had a light flywheel when I test drove it. :dunno:
For owners staying N/A, I'd like to see what the results of ECU tweaks would bring especially after driving for long periods. I'm planning to force feed this motor next year, so hopefully the ECU tweak will also improve low end response.

After I got the exhaust installed, I definitely felt the low end responsiveness was not as quick as stock. After technosquare ECU re-flash, the low end responsiveness is back and the car is pulling harder. Also I have not experienced any lost of responsiveness for an extended period of driving. Also before oil cooler installed, my Z temperature was at 240 during a normal driving and it went up around 260+ for a spirited driving. Again, I didn’t see any change in responsiveness.
The yellow Z in the Technosquare video is KillerBee370's. His Z was a mule for the 09 370Z ECU tuning. He had the first hand experience during the development. He did experience gas pedal delay and went back to technosquare for a minor adjustment. Tadashi of Technosquare did his magic. I’ve heard that technosquare will not offer ECU re-flash on the 2010+.
There are many people on here with UpRev. Maybe they want to chime in if they have experienced with gas pedal delay.
