I've got a stroker motor to tune in a 98 camaro. It was a 4l60 but now it's a t400...not sure if i should use a stick o/s or the existing auto o/s...
Pluss, I need to "AUTO VE" this thing....I don't find anything in the tutorial on this o/s or on the forum....
Can you point me in the right direction? The Ve tables have different resolution between the Backup and Main...
I haven't had to do this one before....and I'm kinda lost.....any advice or custom os or something?

The VE tutorial covers the 98s. The auto "type" question I don't have an answer for. The biggest difference I saw is having to MAP the main and backup VE tables.

BUT, if I want to use the maf on this one...How do I convert the BACKUP table to the main VE table??? The resolution is different??? What now?

If you follow teh AutoVE tutorial, you will be updating the primary and back up thru the process.
:stupid: The autoVE will have you calibrate both tables. I just did my 99 last night. Mine is just a bolton M6 though.

Ross says that when we go SD to do the auto VE...the o/s defaults to the backup VE and I should do the auto ve on the backup.....BUT, what do I do when I turn the MAF back on and the tables are not the same.....
Now What?!?! I'm alittle lost.

Even if the resolution is off, you should still be able to use the main VE and copy and paste with labels to bring the backup table to match.
When tuning a 2k and earlier, one or two places in the AutoVE tutorial are slightly ambigous - do BOTH B0101 and B0103, when setting up the Maps in the Scan tool, do so for both the Main and Backup values, that way you will have the appropriate BENs for both tables!
First, we need to clarify something. The VE here just has to be close if you plan on turning the MAF back on. It's there to back the MAF up incase of failure or when it's response is limited (transitions, low airflow, etc.). Tuning a pre-'01 car in SD is simply done with the backup VE. Get it close enough (+/- 3%) if you can. Then, copy the x0kPa columns from the back up VE to the main VE individually. Fill and hand-smooth the gaps for the x5kPa columns. I usually set the 105kPa column equal to the 100kPa column. The 15kPa row can be guestimated by following the trend for each RPM row. Re-enable the MAF and move on. Once the majority of the MAF is dialed in, look at idle and your transitions. If you transitions and idle are lean/rich, increase/decrease both VE tables slightly (+/- 2%) in the respective areas to eliminate the issue. Don't sweat the small stuff too much or you'll go insane. Tweak/finalize the MAF and be done. Just my $0.02.
