Hi folks
Long time no talk - mainly because my car was running sweet these past coup=
le of years :-)
Had to change the heater hoses, which meant removing and reinstalling the C=
AS. I have reset the timing as per the IGN TRIM +10 screen, however idle sp=
eed is now always around 1,000 rpm. The IDLE% screen is showing 15% no matt=
er what position the idle adjustment screw is at - all the way in or all th=
e way out. When revving, it increases to 30 or so, then back down to 15%. P=
retty 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 pap=
erclip - made no difference to the n.
No other errors or strangeness. All the cabling to the CAS etc is fine. Lot=
s 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 i=
s 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 adap=
tor. I have the AEM wideband and the standard O2 sensors - both are showing=
readings.
Cheers

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.=20

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

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 - sho=
uld this be letting air in at idle ? With its vacuum supply removed it is c=

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 - sho=
uld this be letting air in at idle ? With its vacuum supply removed it is c=
losed 100%

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

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.

Subject: Obiwan not idling properly
Hi folks
Long time no talk - mainly because my car was running sweet these past
couple of years :-)
Had to change the heater hoses, which meant removing and reinstalling
the CAS. 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.
Cheers
Frank

It should not allow air into the vacuum supply hose as that will contribute
to the idle problem. Does the IDLE% rise when the vacuum supply hose is
disconnected and plugged? If so the BOV piston (or sleeve) may be worn out.

It should not allow air into the vacuum supply hose as that will contribute
to the idle problem. Does the IDLE% rise when the vacuum supply hose is
disconnected and plugged? If so the BOV piston (or sleeve) may be worn out.
