Motor keeps wanting to die as soon as I let off the throttle to let it idle. Sometimes holding 4% throttle TQM comes in there too. Data logger shows TQM is the culprit.

Tune is a 1 Bar SD on a 99-02 F-body computer with a 80E segment swap. I no longer have the 80E and run a glide. Did not have this issue with the old combo on pump gas. Trying a new 13-1cr combo on E85 and this is no showing up..

My car is Saturn sky turbo (LNF)

I've purchased the 3 Par sensors and HPtuners and tuned the GMPP tune on my car:D. Knock retards are killing my engine, I have lot of them and can't get red of that :banghead:. I've tried doing MAF calibration but it didn't do me much .

I never scanned my car before the GMPP upgrade so I don't know if i had this before or not. As you're aware I had to cut the old sensors plugs to get the new sensors on, so there is no way back to stock to check for KRs!

Attached is a scan after the last tune for the MAF calibration. any idea on the way forward :drivin:?!

BTW, I saw some threads that says I should start by making all the Spark Advance tables same then scan for KRs and subtract it from it. I really don't understand why I should make it all the same while the car maker didn't on both the stock tune and GMPP tune :shrug: !

Thanks in advance :)

I spent the last week tuning my VE table...hitting as many cells as possible in as steady state as I could get on the street. I tuned this using a VE Lambda error histogram...I did a conversion in hptuners to display my dynojet wideband in units of Lambda. Yes I had my trims and fuel cutoff disabled :). I got everything dialed in very nicely...between .99-1.01 and I verified that across different days and weather patterns..it is rock solid according to my wideband and the car runs VERY smooth. No bucking...I can cruise control at 900 rpms in 6th...the cam is a 227/235.

So today I turned back on my STFTs (I don't use LTFTs) and they were off as high as -12% in some areas! So I figured, ok maybe my lambda calculation was off...so I did another log just logging raw AFR values (again with STFTs off) and every cell I hit was hovering around 14.7 AFR, so I was just about dead on. With the STFTs turned back on, my AFR was consisently in the mid 15s!

A week ago, before I began tuning, I did get the 02 heater codes on both banks, but the code cleared itself and never came back a day later. Could my 02s just be on the way out or is this normal behavior for having headers and a cam? I see people like to run the corvette rear 02 sensors and run an adapter. Could that be my solution? Or should I just run OLSD? ]]> GM V8 Engine Tuning - Gas Vehicles (Gen 3) BigMike42 http://www.hptuners.com/forum/showthread.php?t=39065 Stock LS1 in Colorado? http://www.hptuners.com/forum/showthread.php?t=39064&goto=newpost Wed, 16 May 2012 15:00:21 GMT Hey all, before I toss my snail on, I was hoping to find a bit of a smoother BIN for a stock M6 LS1.

I was dialing in my maf using a MAF-LTFT histogram and now the car hunts after startup then stalls.

I noticed at the idle air flow frequency the LTFT was high (21%). I applied the histogram values to the "MAF Calibration" airflow table as a multiply by %.

If I help it stay running after start via the throttle, it eventually stabilizes and idles.

It gives me the error saying that the VCM can't be found. However we do have a 2007 Tahoe I also tried plugging into and it worked fine.

Both of the 98 vehicles used to work fine with HP tuners. I have even tried with another computer and still no luck.

One thing to keep in mind is that one of the 98 engines is in a 69 camaro as a swap so is there any chance I wired something wrong and broke something in the cable/hptuners box? But if that was the case would it be possible that the 07 tahoe would still read fine???

I need some help as I don't understand why the AFR goes from ~10 before reaching Fuel cutoff (6400 rpm) to ~15.3 when resume fuel.

If I release the trottle for a bit then go WOT again the AFR will stay at ~10 until it hits the cutoff then resume fuel with AFR of ~15.3.

I try to look around in the config file but I couldn't point what making this happening.

I'm racing a Grand Prix GTP (L67 + XP cam + 42.5 injectors) on a circle dirt track and I stay on 1st gear (shifting 2nd gear isn't a good option).

Thanks for helping!
