well, I'm assuming banzai has checked all the pseudo-obvious things...



have you confirmed timing is being advanced? perhaps you forgot a jumper in the initial set coupler?

Timing has been checked SOOOO many times, my car shreiks in fear when the timing light comes out.. Pls I have used 3 different lights to check including a self-powered one that a leading EP Race Engine builder uses(For whatever that is worth)



There is no jumper in the initial set connector.



Here is a thought: The ECU in the car is the Auto ECU. Should I swap in a Manual ECU?

i don't know if the auto ecu cares much about anything auto-specific, but it's worth a try https://www.nopistons.com/forums/pub...IR#>/smile.png



the main reason I would support putting in the standalone is it would either eliminate the problem or give you alot more instrumentation and control over what is going on and probably make discovering the problem easier.



or it will just throw a bunch of new variables into the mess and totally side step the problem causing you mucho headacho. https://www.nopistons.com/forums/pub...#>/biggrin.png

yah swap to a manual ecu, maybe you're on the park map?

Park map?



Hey mike are you an YM? I can't get AIM at work??

um hang on a minute and i dunno

3inch dp on na engien is too big, try 2 1/2 and you can gain some of that torque back. Is the engine ported?

Do you still have the injector air bleeds (atomizer screens) installed in the manifold and center housing?
