Adamw Posted July 15 Report Share Posted July 15 The short pulse width adder looks very wrong to me, for example it is pulling 30% of the PW out at 0.75ms. I would zero that out, your PW's typically wouldn't be short enough to be operating in the very non-linear region with a ~500cc injector.

Coolant temp, alt lamp etc? Quote Link to comment Share on other sites More sharing options...
Nick Murray Posted July 15 Author Report Share Posted July 15 Hey Adam yeah I have zero'd the short pulse width adder yesterday and it dropped the ve to low 60s at idle and cruise, around 105 at peak torque and falling off to 101 at the limiter Only multiplex not working is the ambient temp reading weird and the ac control not working 😕 Quote Link to comment Share on other sites More sharing options...
Nick Murray Posted July 31 Author Report Share Posted July 31 Would anyone have any idea how to sort out the ac issue? i press the ac button in and the ac request(ign 7) shows active but the ac clutch doesnt pull in not sure what ive done wrong but its doing my head in haha Quote Link to comment Share on other sites More sharing options...
Vaughan Posted August 1 Report Share Posted August 1 https://www.sq-engineering.com/wp-content/uploads/2018/11/3S-GE_Wiring_Diagram.pdf Quick google shows that the ECU controls the AC Clutch via a relay with nothing else interfering with the signal. Grab a multimeter and start probing, Ign 7 will be ground when active and floating when active, check the fuse and the power into the relay, check if the relay clicks when ign 7 is set to test PWM while the engine is not running. Also check that your AC Compressor is plugged in. Quote Link to comment Share on other sites More sharing options...
Nick Murray Posted August 2 Author Report Share Posted August 2 hey thanks for the reply my understanding was that the ac was controlled by the multiplex on the is200 definately plugged in i will do some testing now when i get to the relay cheers Quote Link to comment Share on other sites More sharing options...
