Took my X to the track the other night and had some issues I had never run into on previous track outtings. First pass was a very soft launch using the 2-step. mid way down the track I got a CEL. gave it a little gas on the return and my boost stopped at ~15psi. I got out and unplugged the battery to clear whatever code it was.

Next pass I hit the 2 step, let out the clutch, and it felt like it was going to be a great launch. I moved maybe 5 feet and everything died. I thought at first i had stalled it so i went to restart, but the car was already running. LIMP MODE! I had to cover 1/8th of a mile at like 3-5 mph. I unplugged the battery again, tried a launch in an empty part of the parking lot and it did fine for 30-40 feet.

Anyone else had this happen?

My mods are:
AMS mail-in flash
AMS intake
Nisei UICP
UR Down Pipe
UR Mini-Muffler Test Pipe
GReddy Ti-C Cat Back

There was an elevation difference. The track this happened at is quite a bit higher than my usual track.

Any ideas?

 

You need to pull the code... could be any number of things, especially with your mods.

 

You may need to send your computer back to ams, call them and tell them your problem. After my ams mail-in flash I was still having codes and they reflashed it again, no more problems
