Is Trimalyzer for SD tunes only

[A95Y]

Is Trimalyzer not intended for cars with MAF?

Thanks

it has a poorly tested maf analyzer, but for an LT1 i think eehack's built in analyzer would be a better choice for maf tuning

I'm trying to use MAF mode on my 0411, as of now the hard part is datalogging. I can datalog ok, just nothing as good as obd1 with the history tables in tuner pro. Very tough to figure them out without the tables. MAF mode did work on my $OD MAF truck.

why not try to run trimalyzer on your logs

This might be obvious, but how does the analyzer correlate to the changes I can make in the MAF calibration?

It's actually kind of complicated at the moment. So first, take a stock MAF curve and look at it in the graph view in TunerPro. When you're done changing things, you'll want your curve to look something like that.

Second, the "AFGS" value in Trimalyzer/EEHack refer to the number in the second column in TunerPro's MAF table. So if Trimalyzer says "add -19% to 16-20," then go to all the values in the MAF table that have a value of between 16 and 20, and use the multiply function in TunerPro to multiply them by 0.81.

Once you're done with all the values, open up the graph view again, and try to smooth the curve as best you can.

I look forward to the day MAF tuning will be a little more automated, but for now, that's the method.
