ok, thx

I was logging some signals and noted that my DYNAIR and IACDES_B values do not match. As a general rule IACDES_B values are lower than the DYNAIR values by .2 to .4 g/sec. I have not changed the...

Never had the issue before removing the cats. $$ is the issue. Guess I'll have to save up. Is the issue the lack of cats or the fact the O2 sensors are so far away and as the burn fuel moves down...

can't help hear. but i've heard they will refund you money if you are not satisified. Also i've heard when you run the report it will lead you to believe there is something you should know about...

As I battle idle issues I found out that the stock idle learning min was set to 80*C, idle learn max was set to 112*C. The issue is I have a 160*F thermostat installed. The fan temps have been set...

I thought you'd say that. By the way forgot to mention that Air Pump is removed. Would reinstalling help situation. Also the issue is beyond startup. Drive the car for 4 hrs, stop at a light with...

Are any of you experiencing rich fumes. When I start my M6 car in the garage and allow it to warm the exhaust fumes are so rich my eyes burn. If I allow the car to warm with the garage door closed,...

What is the RAFIG Sensitivity? I logged a cold startup in my M6 car from 20*C thru 80*C and only saw RAFIG values of less than 1 gm/sec. That is to say what is significant...8gm/sec or 0.8 gm/sec? ...

SSpdDmon, thanks for keeping me straight.

Brian, I'm fighting the same issue myself. I spent all weekend reading threads about idle tuning, RAFIG, etc. My eyes are still crossed and I'm more confused now than before. I tried to put all...

will do...thx

SSpdDmon, Do you still have that spreadsheet for the MAF % correction avaliable?

The car does not dip when I'm at a stationary idle. It only seems to dip when I'm rolling and push the clutch in.

What spark table is used when the car is started cold and as it warms? Once it's...

sorry for my ignorance. how is RAFIG and RAFPN calculated for a 99 OS?

Well I tried that. I set the base spark in gear and base spark in park/neutral all cells in the low map region and rpm region to 28. However on a cold start the car still idles around 20 deg. Once...

thanks for replies guys. I tried using bidi before but I think I was using actual. I commanded 28 deg. and it idled great but as soon as I turned the bidi off the car reverted to ~20 deg. it surged...

I've got a 99 M6 car that only has stock MAF, LS6 intake, 2.02 heads, 224/224 cam, headers and exhaust. I have performed auto VE tune however instead of remaining in speed density I have returned to...

I guess I should also mention that I have and would like to return to MAF closed loop control. Having read more threads I'm really thinking I need to adjust the MAF. Can someone direct me to a...

Performed head, cam, intake, header, exhaust swap. Car has been idling bad. Went thru Auto Ve tune. Now car is idling worse. Thought about adjusting throttle blade to let more air in but when...

I had the same idea. Here is what I did. I created the initial tune. Drove can and created an initial log. Used initial log to create tune 1. Drove car and created tune 1 log. Used tune 1 log to...

Being that the total differece between banks never exceeds ~4% I'll assume all is well since I can't find any exhaust leaks and the sensors appear to be working correctly.

Knowing that I need to...

After having created calc pids for delta LTFT between bank 1 and 2. I'm seeing some cells bank 1 is about 4% leaner than bank 2. In other cells the are exact or only differ by 1 or 2%. Interesting...

I created a calc pid to look at the difference between the banks. Will log tomorrow.

Swapped sensors. Still no data above a MAP of 30. I tried logging data with different tunes. Finally decided to delete the maps and recreate them for bank 2. Success!! Apparently I made a mistake...

great idea. I also have the 2 sensors (which I believe are the same) that I removed when I stripped out the cats.
