I know I should have a wideband setup by cash has bveen tight. The thing that leads me to really believe the narrow 02's is the fact that Im getting kr at timing levels I didnt used to, I can see...

tried the cylinder balance test and it wont let you do it at high rpms, tried it at different rpms up to about 2100 and they all seemed to be very close. Also did the case relearn while I was there...

no I havent that is a great idea though, Im using 1.7 hopefully that has it.

I have a problem with b1 always being leaner I have swapped 02's and it stays on that side, Even at part throttle B1 tends to be leaner. The difference at wot can be as much as 100 mv and its causing...

Ive been messing with disabling ltft's and tuning with just stft.

Are short term trims "learned" or remembered? Are they cleared whenever the ignition is turned off?

What is the reasoning for doing it this way? Why is the math setup that way?

I just took mine off god I love living in the south

The sheet didnt work for me I hope it does for you it doesnt take as long as my method. Dont forget to reset trims after only major changes to the ve or maf and if you have to use my method and have...

Id like to know about the cot setting condition also, I competely removed mine. But I would think maybe if the rear 02's get really hot then it sets the cot not sure.


figured out my PE problem I...

ok makes sense Im learning

Right on

that ve better be slick as a babys butt provides alot better resolution when you renable to maf it cut my 02 oscillations way down so they are more concentrated on stoich afr

Ive found...

As long as I get some magic slippers in version 3.0 Ill be happy. What your talking about would be cool.

I had set the ifr to 34 and compensated with the ve and maf table to align trims this is what was causing my pe to be rediculously rich no matter what I set it at. I need to do some more looking...

Im using narrowband 02's Im getting mv in the 940 range with the pe table set at 1.112 across the board. Plus I know it is rich because I have lost power.

As far as the injectors I had to adjust...

No matter what I do whenever I enter pe mode it is too rich and not running at commanded afr. Ive even tried setting the whole table 1.112 and I get mv in the 940 range, they do seem to come down...

The more I use this software the more I am beginning to think there are extra parameters and tables we dont have access to. For example I was having problems with getting a consistent afr with pe. I...

yes, I personnaly rarely rely on polynomial smoothing and if I do I make sure that 5 decimals are selected and the table is allready very close.

The reason to have a smoothe ve or maf graph is...

i used several sheets and it sent all my trims -10. You need to have the maf enabled to tune maf table because you can use the trims and maf hz. The trims you see in SD are a direct result of the ve...

jimmy does the airflow measurement come directly from what the maf is reading or is it something that is based off ve and maf tables calculations.

I logged the engine and transmission and there...

I logged engine tq and was hoping that it would relate to 02 readings. Now after looking at the data and researching this doesnt seem to be the case.

Does the delivered tq value have anything to...

here is how I tuned my maf table I simply logged maf hz and then pulled up the logged data in the chart and scanned with the cursor where I saw a trim out of whack I noted the range of the maf hz and...

When are the max or min modifying tables used are they always used or is it just under certain conditions

thanks for the reply chris, I raised the base table so my max would be 7.28 it does seem to help I can run more timing easily with less kr.

One more question what are the guidlines that the max...

but how much time does it take to saturate the GM coils? Maybe Ill call delphi on this one, Im assuming they make the coils?

how about on NA engines you would think better spark more complete combustion less chance of detonation
