Ok, so you have a 8psi supercharger on your Z, correct??? And you took it out to run some laps and it went into limp mode. Where is your oil cooler?

Capitol Raceway is a drag strip.

Let the car cool down over night. Do not start it or try to change anything. I read in a post that you have to let it sit overnight and the ecu will clear the "limp mode signal."

You should reset the ECU. Pulling the negative cable is one way, but you can also use this technique to avoid having to set the windows.

Read the process a few times before you try to do this its ALL ABOUT TIMING:

1) With the key in your pocket/car, push the Engine Start button TWICE (so the car is fully on, but not started)
2) Within three seconds of the car "ON" (again NOT started), Floor (all the way down) and Release the gas pedal fully 5 times within 5 seconds. Do not do this too fast.. 1..2..3..4..5
3) Wait 7 seconds then floor the gas pedal and hold for 10 seconds. After that 10 seconds the Check Engine Light will start to blink slowly.
4) Release the pedal and floor it down once again and hold for 10 seconds. After these 10 seconds the check engine light will disappear then begin to flash much more rapidly. After you have done the following turn the car off and then back on. The ECU is now reset!!
