e38 ecm 06 gto speed density these ls2 computers are a bitch,
i have F1 procharger (80lbs injectors) on my car and we have been trying to run speed density, i have turn the fail #s to 0 for the mass air flow, I turned off all the mass air flow dtc, I would commanded a new lower ve number and it almost seems to fatten up worse ( 9.4) cruising) no matter what ve # i put in
I turned off short and long terms and been using the wideband to do the afrs
In the scanner it still shows as if the mass air is still reading
what all do you turn off to get speed density
also what all do you change to make commanded afr go to 11s at 105kpa
this car is still on 1 bar sensor
the hole reasone i want speed density is my meth kit is before the mass air and its dumping a **** ton of fuel when the meth hits it,
im plucking at it slowly but if somebody has already done this please
any help would be great

Did you swap out an E38 or are you using the stock E40?
you should not spray a meth kit through the maf.
You will likely have to disconnect the maf itself if you want to go SD, who's 2 bar OS are you using? And like Mike said, the LS2 GTO is a E40 ecm, which is a totally different speed density model than the coeficients in the E38

OOO i thought the gto had the e38 ecm sorry
it is the stock ecm
the car is still on the factory map sensor
so can anybody tell me how to go speed density now that i got my facts straight
will the e40 control a 4l80e in the goats?

Yes the 4l80 can be done with a segment swap but no offence it sounds like you need to do a lot of reading. Between this forum, the gto forum, and the tuner forums for what ever software your using u should find plenty of info on your problems. Take the time and learn im not trying to be rude but you will save yourself a lot of time and trouble.
if you are going to run sd removing the maf and wiring up iat should be your first step.

Maybe my terminology is wrong but there are t42 in 2007 + trucks with 4l80s so why can't it be done with a car. I read a thread somewhere this was done using a file from a Yukon. Ill see if I can dig up the thread.

ok so no 4l80, anything to help on speed density? does the mass air need to be unplugged completely to make it work and if so what wires do i need to unpin for the iat

i have a vin for a yukon that has a 4l80. according to efilive supported vehicle page all 4 speeds use a t42. now a 07 yukon should have a e38 according to the same pages. thats why i used the term segment swap because when we flash a vehicle were changing both transmission and engine calibrations even though they are different physical units. so if its in a yukon with a t42 and e38 why cant it be done with a e40 and t42.

should be the two tans yes. the colors should be the same. for some reason the software i have that came with my scanners skips 2005-6 gto's so i pulled up a 2005 ls2 vette which is a year for a e40 same as the gto so it should be the same. the iat works of resistance so yes its just two wires. the plug may also have the letters on it as well.
these ls2 computers are a bitch,

will a iat work out of a ls1 camaro/s10??
will the cobalt ss map sensor work for my app.????? if not part # please
to go 2bar i need to buy more credits? (hp tuners)
does anybody have a ve table i can go off for the boosted side, i turned on the 2bar a while back just to see what all it consisted of and the ve table was 0ed out above 105kpa
never went 2bar on any of my vehicles, so this will be a learning experiment
thanks for the input guys

Why would you want to use someone else's VE on your car? Don't say "to get it close to start with". 
12615136 is the GM 2bar MAP number.
If you want to run an 80, you need to use a TCM/calibration for a 60 and do a little wiring so that that you can elim the TCC PWM and get the noids back in order and then you can run it. Or at least, I would.
