I can see that the LT1 works a little different than the LS1...
Or is it the same just seen by a differetn perspective?

 

wot does not lock the blms to 128 (unless you use the blm locker). when you go wot it goes into pe mode. and if your lt blms are above 128 the instant you go into pe mode it will add the same amount of fuel it was adding in normal mode to your pe mode

 

Like I said before, MY CAR repsonds to VE table changes and it is a 1997 OBD2 Trans-Am. I cannot vouch for ANYONE ELSES car and what it will or will not respond to.

 

It is known that the obd2 uses the VE tables

 

obd1 does as well. ive put that to the test.

 

Unfortunately, that is flawed reasoning/math. VE is not a measurement of the amount of air ingested by the engine, (or IOW, the air pump). VE is the the amount of air actually used (ignited, combusted, with it's energy exerted against piston crown) by that air pump. If the air goes in, but ends up coming out unused (or used very inefficiently), why account for it in the VE tables? Same principle if there are holes in two pistons, or a leak in the intake tract, post MAF. This is the reason % of VE at idle/low speed, is affected with the use of cam timing more aggressive than oem. The air is still being pulled in, but not utilized to push piston downward. Same reason the VE of an engine will change/deteriorate with use/mileage, due to compromising of ring seal. There is more to VE than getting the air past the throttle blades. Because the MAF system can do a superior job of compensating for changing VE, it was choice of engineers to maintain emission compliance, for the EPA mandated time requirement.

It wouldn't make sense to use a table if you could get a REAL number.

There is more calculation done by pcm to utilize the MAF input, than when the SD mode of air measurement is used. The reason SD is more responsive.

Now that you mentioned it...... And, my attitude (with respect to this topic) probably won't change unless I'm convinced carcraft employs some the engineers, that were part of the team GM used to assemble their pcm code. IMO, their sales are influenced heavily by sensationalism. Their product was not meant to replace formal training/instruction.

...(and other PAID tuners for that matter)

Some are very knowledgeable, some are paid more than their efforts/results are worth. Next thing you'll tell us, all doctors are equal in terms of benefit they give to their patients.

BTW, there appears to have been minor alterations in pcm code to allow the VE tables to play a more active roll in the A/F calculations in pcm(s) of OBDII vehicles.
