PMAS intake w/tune stalling on warm start

[WildHorse]

Do you now get about 10% TPS at 650 RPM hot idle ?

Mine shows 10.20% @ 623.3 rpm hot.

I don’t remember, but I’ll do a start up tomorrow and take a pic of it.

Are you guys monitoring TPS via nGauge or some other tuner?

Hey, if it works, that’s all that matters. LOL

Actually it ain't bad. That CMR software has so many fricken features, so much datalog options, way way more than anything outta the HP tuners camp. Diablosport has a lot of time on their hands haha. Best part is I can load a .hpt tune right from the ecm onto the diablo, return the pcm to stock with the HP tuner, then load that exact tune from the diablo to the pcm as a .frg.

Ok, here’s what I got GregO..

Before adjustment. Disregard rpm, as I didn’t let it settle down to normal idle speed after cold start.

After adjusting TPS voltage.

Looks like I may be good here after the adjustment! I’ll know for certain once I take the car out for a nice drive.

Check your clamps to make sure there is no air leaks. Also sounds like it could possibly be a maf sensor issue.

Thank you! Champs checked for tightness prior to every drive. I sure hope the MAF sensor isn’t bad. I only have about 1K miles on my PMAS air intake setup. I purchased new from you guys.

You failed to mention your running E85, or I didn't see where you mentioned it haha.

Whoops! Yup, I need every bit of power that my combination is capable of providing (fuel included) Haha

Then disregard everything I said cause I know shit about tuning E85, mainly cause there's zero access to it here. Apologies for wasting your time.

NP, I don’t see it as a waste of time though, as there’s always something to be learned on any given day, about any given subject.

Gen. 3 Mustang owners take a look at this video guys. It addresses surging idle. The culprit may be bad cam phasers. I wonder if CAI kit issues could be confused with this issue? Hmm.
