IAC on turbo v8 Help needed

[vp304]

Oh also vn5000 checked tps throttle shut is showing 0%
Full throtle is showing 98-100%

[Jayme]

just ticking 2 bar should fix up the tps problem and timing. is your dizzy set to 10 deg base advance in diag mode? maybe it was retarded a bit and stopped it pingin?

[vp304]

Its set on 12 deg in diagnostic mode from the na days lol. I know it should be on 10 but it was set about 5 years ago b4 i knew abt tuning and burning chips lol

[vn5000]

Had a look at your bin and as jamye says its set to 1 bar.
My suggestion to unset code 19 was only meant as a test if you did what Jayme said (set 2 bar) and you still had the problem.
If you are getting 0% and 100% readings on tps then tps sensor must be ok . ithought i read that you werent getting the full range before.My mistake.

[vp304]

It was a few years ago but i musta fixed it along the line somewere. Still cant believe the timing and that it hasnt done a headgasket and ive done about 400ks since hooking it all up. Done 150ks in 1 night

Do you guys think setting the tune to 2 bar will fix my iac problems?

Just a stab in the dark.
You said earlier that it was an auto converted to manual.
I haven't seen your log but on your TP dash,is your closed loop idle showing set or clear at idle?

On my auto at idle in park,it shows set.
As i have a munro with the original T-bar set up,i had to rig up a way of grounding the P/N wire to the ECU in park.
With a sloppy T-bar i can make it show "set or clear" and the rate of rev change and AF ratio of roughly 100-200 rpm and .50 afr
I know the manuals didn't need the grounded wire,but if you still have the auto loom in there,ground the P/N wire and take a log showing it being grounded and not grounded.
Mine definetly idles better in park.
Worth a shot as someone on here may find something.

Was manual on 5d custom tune for over 2 years ran like a dream. But thanks for the info mate will see tomorow how i go with setting 2 bar on the tune

[vp304]

Well you guys are geniuses. I couldnt thank yous enough 1 tick and the car is working perfect
Car runs like a dream iac working perfect here is a log below. Only problem is now its using correct timing its slow as Gonna have to get the knock sensor wired up maybe throw another 2 deg on the boost map see how i go and the 10psi spring

[vp304]

On a turbo blown car is the manifold air temp of 60deg anything to worry about? High low ? whats normal ?

[Jayme]

id definitely be checkin the base timing again. it really should have been way way too much advance and pinging its head off. maybe your dizzy has moved in the last 5 years?
havent looked at the log, but 60 deg on manifold temp sensor is low.
