m20 turbo war chip idle tune

[BMWZ318is]

I have a m20 with a t3t4 turbo running 30lb injectors with 40 psi for fuel pressure the idle on my car sucks when i first start it it gets a little better once its warms up any one have any good tunes?

Do you have any pictures of your setup?

When you first start the car it enters the warm up phase and ignores all of the adjustments that you made to the AFM wheel (if you made any). This could be one of your issues.

After the car is warmed up, how does it idle?

Looks like a nice setup.

When you first put in the chip, did you adjust the afm wheel at all? It's the little wheel under the AFM cover on the intake side.

[BMWZ318is]

no i didnt know there was anything you could adjust on there

so i turned that wheel on the afm and it is running alot better thanks for the advice man. i also hat to change my stock rubber intake boot cause it had two thumb size holes in it.

Yeah those things theme to split under boost

[jaywood]

You can wrap the stock AFM boot in fiberglass if you want to make it stronger (I've seen tape and zip ties work as well). I think those things fail at ~8 lbs of boost depending on your turbo.

I'm glad the AFM wheel helped. How many clicks did you go over? Do you have an RRFPR/wideband?

I'd highly suggest a silicone air intake boot. If only there was a company who made one.

im not really sure just turned it till it ran better ha ha. i have a rrfpr from IE im running 8lbs of boost right now and its running pretty good i need to get the miller maf or switch to ms2 im not sure wich is better.

Everyone is gonna tell you that MS2 is better. Whodwho builds boxes that allows you car to be running in 30 minutes after installation.
