I have a 2002 TA with a LS1, 383. I switched to another PCM, now I have an error code P1336 CRANKSHAFT VARIATION RELEARN. I tried doing the VCM Controls, then special, then Case learn. I followed the...

I understand that the inlet system can effect the total amount of air that the engine could ingest (essentially the differences in pressure drop), but a set velocity across the MAF will trigger a set...

I have been looking at the 3800Pro.com forum in which "Mr Intense" has a MAF table repository. The tables shows that the 1998-2004 Corvette all has the same numbers while the 1998-2002 F-body and...

I want to soften my 1-2 shift at Wide Open throttle only on my 4L60e trans. Do I go into shift pressure tab and under "performance" change my values? Is the "performance" tab meaning at WOT?

I have a 2002 Trans Am with the 4L60E transmission. The problem is, the 1-2 shift at wide open throttle will break the tires loose. What is the best way to soften the 1-2 shift so I don't loose time...

Can you program the EOI output to command a light to come on (knock retard) without having the computer hooked up to the interface unit? Would the interface unit need to have the record button pushed...

It’s a known bug in the current beta version- no fix out yet.

When I try to input the parameters into the EIO Output, I can enter all the input/output triggers, but when I close it does not save the info. Anyone else have this problem? Another thread indicates...

What is the difference between a 12200411 & 12212156 PCM?

Looking for anyone who has the VCM Pro version 4 sale, GM only. Have the standard, want to upgrade, but the price is high for just an upgrade.

I added the 2-bar MAP thru the HP tuner which I then went thru the procedure for updating the primary VE vs rpm vs MAP table (which now shows 210 kpa. I assume you mean for the fail freq set to zero...

If I add a 2 Bar MAP, will this force the ECM into Speed Density? Reason I am asking, is that I noticed that the MAF has not been disabled.

OK, so when I re-enable the MAF, then the chart for the MAP will still show the rescaled values? Also, how did you adjust the primary VE vs MAP vs rpm table? Did you leave it stock? By the way, what...

Right now I have a 1 Bar MAP. My injectors are 42LB/hr and the cam is a Z06(.550 lift 205/218). MAC mid length headers, high flow metallic CATS, Patriot heads. Forged crank, pistons & rods. I have a...

Anyone have a VE table for a 2002 Trans AM LS1, 383ci with a Vortech supercharger putting out 9psi?

Is there a way to add a 2 Bar MAP tune to an LS1 application using a MAF sensor? If not, why not HPTuner?
Note: I do not what to go to Speed Density tune.
