ported engine, 850 primaries 1600cc secondaries. i got the the power fc re-mapped by rx7.com rotary performance for the set-up on this car. single turbo.. i put the wideband and went for a few 12psi of boost runs on the local roads.. car ran strong and safe on the air fuel mixtures. but out of no where, it stalled. car lost spark, fuel pressure and injector signal. I took out the power fc, installed the stock ecu just for trouble shooting and the car started right up. has this happen to anyone else before? the power fc went bad..

 

Resistors installed on the secondaries?

 

my thoughts exactly.
you have to make sure the injectors you used are high impedance, if they are low impedance then you need to use resistors.

this can blow your power fc. electronics store normally can fix them depending of course on the damage

 

That sucks to hear ITO. You can send it back to Apexi for them to diagnose it. They charge 75 for the inspection and add onto that with labor. If you have someone familiar with electronics and is good at soldering boards you can do it inexpensively...

 

yes, i installed the resistors, got them directly from rx7.com

 

Have you opened up the Power FC to inspect it? Also are any of the boxes checked in the Sensor table?

Even if the ECU shut off fuel pressure should still be maintained.

What are your F/C values in Settings 1?

 

Only if the fuel system is wired directly as to bypass ECU control. The ECU controls the EGI and all fuel system relays.

 

Aren't you supposed to be on vacation

Thanks for the info I thought there was always pressure in the system.

 

Yes I am, but I am keeping a low profile.

 

Think it was $50 i had mine sent out 3 months ago for other issues.

 

You must have got a nicer sales rep
