Maybe not. If he is bypassing the iac and forcing a higher idle with the throttle stop screw, Then adjusted the tps to .44 at this stage. The MAF will show a higher reading. Let him adjust the tps to 44 with a 600-650 idle the see what the MAF reports

maybe, maybe not...for sure the iac is adjusted incorrectly... but the numbers at the warmed up readings are 900 at 12 af which is not too far off.  As you say, he is using the iac screw to adjust the idle speed with.  If he backs it out when warm, the tps voltage will drop and may need to be readjusted before it is all said and done.  Long as it is between 0.38-0.044 all should be good.

Altho I think I said it seemed to be too lean in my last post, it is way rich from what he is saying...that seems to go with his maf numbers.

I would certainly follow your advice to get it warmed up before setting tps and iac.

I will certainly try this as soon as I get the dash back together again. Is there any way to test the MAF? Or by the numbers its showing enough to just swap it out? That is after I run the the tps voltage down. ([size=78%] I think I did this when I 1st set it up but can't hurt) [/size]

I just looked at your signature and see you have a translator.  They seldom fail.  I think I would make sure the dip switches and other thumbwheel switches are set properly for a TT chip.

I would also make sure that the grounds are good.

normally, the maf should read 3 with the key on, engine not running...Tran slator might read slightly different.  I don't have anything with a maf  or a translator installed.  Perhaps someone else can verify what their translator reads with the KOEOff

What maf are you running? I will check in the am what the maf is koeoff if no one else knows already.

As stated, the maf should read 3 with the key on, engine off.

Your signature is saying the car has a translator which must have a late model LT or LS maf.

Could you please clarify?  Factory maf and no translator OR late model maf with translator?

 Is the maf on right, arrow pointing toward intake?
The settings in the translator are different for an extender and TT chip,
Just throwing out ideas.

Okay...85mm LS or Z06 maf, I think.  Here is a thread from Eric on it  http://turbotweak.com/forum/index.php?threads/tip-in-stumble-with-z06-maf-and-translator.1728/

I would start by ensuring the translator is set on the thumbwheels for this maf on the default settings, and I would set the dip switches for the TT chip...or be sure that they are already set properly.

Dip switches for Erics chip are on on on off. Z06 MAF requires the base knob to be set to 6. A special 3 to 5 pin wire is required as well...availab le from FT. Same setup I have on my POS.

Well CRAP! I had the base set @ 0! Now I have to hurry and finish the dash wiring so I can check whether that's the problem.  I hope it's that easy.
 Thanks for making me double (really triple) check that setting.

Stars and runs MUCH better! ('magin that?)
 Still need to give it a bit of throttle to start but not running rich. Idles smooth. But now I have to chase down an electrical gremlin that I didn't have before I pulled the dash. When the fan starts it pulls the voltage down so far the car almost stops. And the voltage seems to not be steady on the Scanmaster. Bouncing around from 12.1 -13.8 at a steady idle. Gotta be a ground as the alt puts out 13.8

Be sure to go back and set the iac and tps right, if you have not.

It does not have to be a ground.  But make sure the ecm is showing a good ground.  You might take your meter to the ecm fuse and read the voltage at that point using a chassis ground as well as the ecm case and see if you see a different voltage.

Will do. Everything has its own ground. (plastic car) :eek: Doesn't mean I didn't miss one. 
 I think the alt. is showing its age. Should have around 14.5v at idle..13.8 its not charging the battery enough between start-ups.
