The GM scan tools have a button to reset learned throttle "coking" so they'll learn faster after cleaning the TB...without it, it takes longer for it to learn to idle again.

I might do just this...I'm very tired of fighting the idle in my car with this flywheel...makes me never want to drive it.

You can't segment swap a 2002 trans segment into a 99 OS...that's probably why it didn't work...it probably didn't copy anything to begin with. You can only segment swap (most of the time) when you...

B1651/1652 are hard limits on throttle percentage. It doesn't matter how high a number you put in B1829, it won't go above 1651/1652 and will not be able to run when cold. That's the flaw in the...

String customers along for 2 years and then that's all we get???

Anybody want to buy a V2?

hymey, my cam is 262.2 advertised duration on a 109.6 centerline. Does this mean I should zero out B1206, and then enter -1*(109.6-131.1)+360+10 or 391.5 (I'm sure 390-395 would be ok too) into...

I'm curious to see your newer techniques. I can get the basic idle down in my car, but I still run into annoying dips and whatnot now and then.

Just curious. If you do, can you share? Just looking for a stock file.

My opinion (also been tuning for 12 or 13 years now) is to stick with the 2002 PCM and use the EFILive enhancements if applicable. There are also a LOT of other tricks for doing what you want with...

I just found ...EFI Live\V7.5\Installation Defaults\Bins\Custom OS\ ...they're all there.

This folder doesn't exist on my computer...I have commercial scan&tune...did I do something wrong at install?

I've got a 2010 Camaro running 12637084 in the E38...my car is an M6, but I've tuned a friends car with the same OS in the E38 that's an A6 (T43 car).

I've been thinking about putting a 4L80E in...

So if I set B8034 to the max that the MAP can actually read, then the injector flowrate will calculate properly when in boost? Awesome!!! Thank you.

I don't think you'll see wheel spin that way as there's no slip between the drive wheels and the trans output...if they're slipping or not slipping, the ratio of the tire speed versus the output...

I zero'd out the throttle follower this morning before work and I'm pleased...I need to learn how to drive the car again lol...I actually have to use the gas pedal to rev the engine to start from a...

Yeah, that's my plan for the weekend with the 102...I'll pull it off and check it out. It's all hand ported, to match my heads, but when I reassembled it I did use blue thread locker on the screws...

I brought the B1651/1652 values up to 1.5 and the car started...poorly but it started...stinks like fuel when it's trying to crank...never had that problem before. :(

I'm lost.

I went through this thread yesterday and tried to use the procedure posted by hymey all in search of a better (smoother) idle and maybe dial away some light throttle surging in my car...but I think...

I haven't tuned a 2011, but my coworkers 2010 A6 car has the same OS as my 2010 M6 car, the only thing I'd be worried about is if enabling VVT properly requires access to more...

Joe,

Do you mean B4001? If so, this table already covers from a 128 KPA delta to a 624 KPA delta, and the information in it is correct. The problem is that the once the MAP sensor actually goes...

The LS9 and LSA operating systems seem to properly correct injector flowrate when they enter boost, but it seems all other E67 OS's, as well as I believe all E38 OS's stop correcting injector...

Did you ever research this anymore? I see that B8036 on my LS3 Camaro is set to 9590...and going on what I know about the size if the intake ports, manifold runners, plenum, and a rough guess at how...

Is no news still good news Cindy? One of my friends is ITCHING to tune his 2004 truck!!!

I'm really impressed with the 124 mph!!! Is that car stock weight other than the wheel/tire combo? Congrats!!!
