posted in other section and thought this might be better place..

Hooked up the neo, dyno tuned it and it runs fantastic.... except that after several passes the engine goes into a kind of limp mode and won't go over 6000rpm. Reset ECU and it runs great again for maybe up to 10 high rpm runs before cutting out again.

Any ideas?

 

I'd suggest...

1. Keep it plugged in, keep a note of your setting/adjustments and set all to 0 then try it several times.

2. What the AFR? whats the wiring like?

3. Hi>lo, lo>hi?

 

yeah best bet is to post all your settings for review...

 

Thanks guys. I think it was the blue/white wire going to the VSS (Vehicle Speed Sensor); pin 9 in the A plug. It was loose.
