Current Donation Goals
I recently imported my dream bh5 in the purple/ blue colour, auto ej206 which I'm fine with, it has 49,000 k"s and upon inspection it has had a centre decat and muffler delete and a back box from zero sports. It's a rev C from 2000 and I'm looking to get a base tune or Remap. I contacted possum bourne here in auckland but they are unable to tune the rev C ecu for some reason? Would anyone be able to point me in a direction of a tuner in auckland? Someone also mentioned on here about project lambda, I was wondering if anyone has had experience with them and if it's worth it. Thanks guys!
Just after some ideas on how to diagnose an erratic idle on a '99 GTB RevB. It's had that common minor shudder while idling for years (subaru thing?), but recently after a long trip it's got much worse. Doesn't stall, but tacho (dash) fluctuates between about 500-700rpm, and stutters and shudders every second or so. Feel like it will stall. No difference whether engine warm or cold. Once revs are >1500, runs and boosts well.
Things I've tried:
-Intake leak test (smoke). Nada.
-IACV - cleaned, and replaced with another from pick-a-part, but no difference
-AFM - Cleaned, but not tried with another yet (I need to get my hands on one)
-O2 sensor replaced with new (old had open circuit heater)
-All intake and vacuum piping checked & replaced about 3 months ago
-Air filter checked/cleaned
-BBOD cleaned and checked
-Boost solenoid (guard) checked and cleaned
-Injector plugs look fine
-Spark plugs replaced a few months back
Since it runs well under power, I figure fuel pump is ok? But it's on my list to replace the fuel filter soon.
I've got FreeSSM+VagCom hooked up and can get live values from the ECU/Sensors, if that's any help?
