Hi,

Sorry to hijack the thread. But what tool did you use to read the Simos 8.33 ECU? I ordered kess v2 but figured it doesnt read the Q7 TFSI ECU. Any help would be appreciated.

Turned on NBs and tried to dial in MAF again today. Tried with filters to filter out possible decel data. Still having issues dialing in lower MAF frequencies.
Also bucking became worse and car...

So I did another change today to see if the jerk issues get reduced. I added 3 deg to Idle Base spark and coastdown as I saw spark literally going in -ve during decel. Also added 1 g/s to the base...

Thank you once again. I did lower the MAF fail frequency. Car is not stalling. I decide to dial in vve first. Got it dialed in(thats what I think) and moved back to MAF. Tried to tune MAF with...

Thank you Proxses. I did see that today while going over logs. The low MAF fail frequency is set to 1126HZ but its failing MAF at 1148HZ itself.
Are you recommending to lower this low MAF...

Also looking for suggestion on why car decided to die. If you look at the log at 13min you can see RPM dropped to zero, oil pressure dropped, throttle % dropped to zero. I had to start the car again....

Thank you @kevin87turbot for the reply.
I am trying to keep o2s and LTFTs out of equation and trying to dial in MAF, hence running MAF only. My understanding is for that you need to be in open loop....

I swapped Airaid CAI with Halltech MF108 today. Car was running pretty good before but after installing Halltech MF 108 everything has gone haywire. Running in MAF only mode, its reading insanely...

Thank you once again. I will definitely try changing sensor settings and see if knock goes away if not will try to pull some timing and smooth out the table. Also I will try manually editing some of...

Based on my research so far on forum here I found math similar to what BigTuner mentioned. I simply used % difference between the sizes. e.g. in your case (102/75)x(75mm ETC scalar area). But I will...

Thank you for the quick reply. I did check for rattling. That was my suspicion too. But ruled out rattling. Did try to desensitize the knock sensors by changing the multipliers but didnt touch the...

Hi,

Newbie here. I have 2009 C6 with few bolt ons( CAI, Long tube headers, catted xpipe, Fast 102, ported throttle body, bbe exhaust).
I was able to get MAF tuned pretty close but having issue...

Still trying to find an answer. May be i will start another thread since there is no response yet

attaching few more log files. Also forgot to mention I have AEM Wideband ODBII.
I did try to find answers in the forum here as well as corvetteforum but stuck on the knock part as well as the MAF...

Hi,

I am new to the tuning. Been reading Greg Banish book and listening to his DVD. I have 2009 ls3 with below mods:
1. Airaid cai
2. ARH long tube headers, catted x pipe and Borla S type...
