Fitted new injector parts and the idle is now down from 1100rpm to 950rpm, IDLE% still drops to 15%.
The BOV (FM aluminium version) hisses like mad when the car is idling - should this be letting air in at idle ? With its vacuum supply removed it is closed 100% -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Frank Smyth Sent: 25 September 2008 13:59 To: [email protected] Subject: RE: Obiwan not idling properly Found three problems - one of the injectors is leaking air into the manifold - the downpipe is cracked at its elbow where it's bolted to the SBB turbo - the one-way-valve on the camcover to inlet-valve is open both ways Looks like idle problem is mainly the injector seals -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Cardell Sent: 23 September 2008 20:26 To: Frank Smyth; [email protected] Subject: RE: Obiwan not idling properly All together now-vacuum leak. Your IAC is hitting its bottom limit trying to hit idle target, but air is getting to the head some other way. Unless you used the wrong notch on the crank pulley and you're 10 extra degrees advanced.....this would lead to same bottoming of duty cycle.

I have reset the timing as per the IGN TRIM +10 screen, however idle speed is now always around 1,000 rpm. The IDLE% screen is showing 15% no matter what position the idle adjustment screw is at - all the way in or all the way out. When revving, it increases to 30 or so, then back down to 15%. Pretty sure I had this around 28% previously. One other thing is odd - in the IDLE screen, I am seeing the *n, with the * disappearing per design. However, putting the clutch in does not make the n disappear. Should it ? It disappears when the car is in gear and moving. I removed the wires from the clutch-pedal switch and joined them with a paperclip - made no difference to the n. No other errors or strangeness. All the cabling to the CAS etc is fine. Lots of 9s on the L3 readout whereas it was fairly well tuned before. Smells a bit too, and is down on power. CAS is fine, I guess, the RPM readout etc is fine, and no CAS errors reported. Is there any other failure mode for the CAS ? It's the only item I disturbed other than shifting the coilpacks out of the way. Sorry, I don't have any logs - have to go on a long hunt for my Serial adaptor. I have the AEM wideband and the standard O2 sensors - both are showing readings.
