UpRev ECU tune results for Semtex's Z

Forrest

Hope this helps you with the "cold starts" and having a tune.

I have no tune and zero mods.

Every now and again i start my car like normal and the mother beep LURCHES foward. Then with out the foot off the gas, the car starts racing foward like im pushing down hard so i have to shift it to second to get it to stop doing that.

Then a new thing happened, i lurched foward and started to race, then it totaly stops like it stop recieving gas, then apply alot of gas again jerk me foward, then stop applying gas and let it slow down, apply alot of gas and lurch me foward again. All while my foot was off the gas, clutch and break. If any of you was to watch me from outside the car it would look like a novice is just learning the clutch and pushing it in and out while foot on the gas.

This does not happen all the time, but i know to let the car sit for like 3-5 minutes before driving.

Hope this info helps those who are fearful the tune is causing the problem.

ps at like 33 degree's c, the z feels monsterously powerful.
