Hi, had another crack at it today with a few results.
I found i had a few wires the wrong way around on the Igniter, no tacho, but have set them correctly and now tacho works fine.
It seems the car doesn't like to run or rev with the ISC connected!
if i disconnect it i can make the car rev which sounds smooth but it still won't idle?
on the 165 system if you disconect the ISC the car runs at 1k RPM as it should.
I get the same results running a st205 ecu as a rev3 ecu.
When the car does stall i can hear the fuel pump continue to run for 3 seconds after.
I bridged the AFM connector pins to enable the fuel pump to run full time, same has been tried in the diagnostic socket, and the car still doen't run any better.
I have a Fuel pump relay which was modified years back to run the pump @ 13V constant, again same results.
Adjusted the st165 Throttle position sensor to both extremes.. again same results
Unplugged O2 sensor... guess what
same results :-(
Again NO error codes, car fires on the button no problem.
Any one throw any ideas my way?
TIA
