DM and idle

#1 Post by kevin00 »

Ive been tring to get this thing to idle right for a long time today and I need some ideas on what to look for next because i'm out.
problem:
wont start up unless I crack the throttle to about 11% on the throttle position. and wont idle if i let off.
what ive tried:
tried adjusting the offset and flowrate.
offset was .8
flow was 2500

any other ideas guys, because im so tired of tring to figure it out by myself.
thanks.

OK I think I figured it out after I had a few beers to clear up my head. smile.gif
But....

Needs to be richened up though the header was glowing just sitting at idle. sad.gif
I've bumped the IO to 1 and the flow is down two 2400 and it still glows. Its a full HMF BTW.
the thing dosent pop or sputter when revved up but that header is getting awfully warm. I'll take it for a ride tomorrow to make sure of no pops or anything.
is this just a thing I will have to put up with or is something still wrong?

****** could you look up the orignals for me? I want to double check. and for future refrence.

Have you recently loaded a HEX code into it?Make sure you have the newest since there are a few that will cause exactly what you describe.Lean condition caused by open IACV which HEX operates.

Nope never messed around with hex codes at all.
I'm beginning to think its the IACV.
there is a IACV position sensor on the monitor screen isnt there? could this tell me anything?

No not really.The reading doesnt actually read position of valve just where it is supposed to be.Is your idle screw backed out real far and still idles high?Best way I like to test IACV is with a COLD motor start engine,listen to idle,remove plug from temp sensor.Idle should change noticably.

No I think I took care of the idle. I got it set at around 2100 at about 3.6%.

If I let it just sit there and never even give it any revs the header still starts to glow.

thanks 27, i'll give that a try if that dont work i guess ill have to start reading up on HEX codes because I know nothing about them right now. :confused:
or should i download a new code anyway just to be certain, it cant be that hard right?

It sounds as though you are very close to getting it right.If you have accomplished a 2100 idle I doubt the IACV is stuck and HEX is fine.Just some fine tuning on offset to go a little richer.
