replaced everything including a DME. when I checked the MAF voltage again only got .58v at idle. made an email yesterday and making a call today since the last email and call I made never got returned.

I'll just keep posting here until someone figures it out. I just got a great deal on another ECU, also, my car is a silver label, anyone running a red label? any difference, I know it SHOULDNT matter seeing as the EWS is the only difference.

On another note, while messing around yesterday, I got the car to pop a 1216 and a 1282 code, TPS Potentiometer and Fault Memory Error, which is what prompted me to pick up another ECU. TPS is brand new (third one, because I kept thinking the car wasn't using the idle circuit if the TPS wasn't reading right because I wasn't able to change idle fuel in the tune). Hell if I know. I guess I'll try the cam sensor next. I thought I got a 1244 code (cam sensor) but I went thru all the codes again and I only got the 1282 and 1216... hell I have no clue. I should just replace every sensor on the car and see what happens at this point.

Got some work done today, vanos seals replaced, started tuning some... got it driving OKAY... the turbo base tune Miller supplied basically doesn't nothing at this point, but it used to run great. knowing my MAF is in spec was a good start, but i ran across this today. may be the solution for a couple of us? a weird solution tho, I've never ever ever touched my idle screw.

ECU grounded, MAF reads .76-.79v at idle. just replaced vanos seals, rest of the motor relatively solid. no vacuum or boost leaks. Still confused. Hoping this is on my end. Going to try tuning it out some more. I still don't understand why the idle tuning tables don't affect idle at all.

This is a long shot, but I just pulled apart the top end of my motor, and since I've boosted the car (and this running issue slowly started happening) I realized my VANOS seal is DONE for! Parts on order, not sure if this could be the cause, but the known symptoms sure point in that direction, and other than that everything on the motor looks fine. Maybe someone from Miller could comment if that could cause these issues? I'll reply once the parts come in.

ECU is and has been grounded as you described, I'll get a MAF reading tonight when I get home, maybe the other guys with this issue can post up their results also.

I've had and been working on this issue since last spring with no avail, and also can't get ahold of them now. About to dump this kit and go RK. Happy to know it's not just my car being a freak.

I've tried it on, off, everything. No change. Understood on the lack of time! The cold New England weather with no garage to currently use plus work and my family are slowing my wrench time. I've tried emailing and calling Miller with no response, slowly losing faith in this setup especially when a compression and boost/vacuum test both check out okay on my motor and my entire fuel system is new, injectors have been flow tested and have new filters, TPS is new, ICV is functioning properly, crank and cam sensors are new, MAF is clean and only has 1000 miles on it, the only things left are the air metering and ECU/tune. I'm actually on a silver label DME, I may bite the bullet and buy a red label to try (I hate spending money on shots in the dark), but after that this car is either getting a standalone/some other tuning setup or parted out. I'm very much over this at this point all last year it sat as I tried troubleshooting it, and have had other certified mechanic and BMW mechanic and insane gear head friends all get baffled by it still having issues. I don't want to band aid it, I want to fix it.

Hey man! Glad your car is running great! I have literally this EXACT same issue that I've had 0 luck solving. Still trying to troubleshoot it to this day. I'm pulling about 20in of vacuum at idle and it loses it as it leans out, until a quick feather and back to rich idle. BOV being open as it's still metered air as it's pre-MAF shouldn't cause issue, unless it's causing turbulence. Random question, but was your car equipped with ASC from factory? This may sound weird, but my car ran GREAT when I first put it together, but I actually had my TPS plugged into the ASC "TPS" plug but obviously forever had a CEL for no TPS. Once I realized I had it in the wrong plug I corrected that, and my CEL went away, but that's when my problems started. I actually slowly started getting more lean conditions over the course of driving it. this may sound stupid but I'm out of options, I'm going to try and splice the ASC and TPS cables so the ECU sees response from "both". I'm really out of options unless my brand new MAF is bad or some other sensor that controls idle circuit that I don't know about went out... but even O2 sensors on/off still nothing. I'll check back every once in a while to see if you make any leway and if I find anything I'll post it up here. We can't be the only two with this problem! My build is very similar to yours also, could small differences that wouldn't do anything. I've changed the FPR on my car as well as flow tested my injectors to no avail.

I literally had this EXACT same problem, but it happened after I ran the turbo base file for a while. As of right now I turned O2 sensors ON and added 40-50 points across P/T HP/TQ maps, along with 40-50 points in both WOT maps. Car runs at about 14.7 cruising out of boost and 11.5 at 15psi flat to redline.

Now I'm having idle issues where the car runs extremely rich at idle and in p/t conditions (11:1) when it's warming up that changing the tune doesn't seem to fix, then when it's completely up to temp it idles like crap and dies most of the time (mind you I completely got rid of the CT based idle fuel and p/t additions.) Tomorrow I'll be turning o2 sensors off and trying to dial that in some more and solve the issue.

Hope this gets you on the right track.
