What ECU to use with 6.0L LQ9??
I want to build an LQ9 with LS6 intake, ported TB, TSP 228R cam running painless wiring kit.
Do i need a camaro ECU even though its made for a 5.7L? or should i run the escalade ECU the motor is out of even though its not designed for power? I know either way it'll need a tune so does it even matter?
Thanks,
Jeff

1999 - 2001 Camaro/Firebird/Corvette LS1 = 9354896 = 512kb
2002 - 2003 Camaro/Firebird/Corvette LS1 = 12200411 = 512kb
2004 Corvette & 2004 GTO = 12586242 = 1mb
2004 - 2005 Cadillac CTS-V = 12586242, 12589463 = 1mb
2002 - 2004 Holden = 12200411 = 512kb
1999 - 2000 LS1 Trucks (4.3L, 4.8L, 5.3L, 6.0L) = 9354896 = 512kb
2001 - 2002 LS1 Trucks (4.3L, 4.8L, 5.3L, 6.0L) = 12200411 = 512kb

2006 - 2007* LS1 Trucks (4.3L, 4.8L, 5.3L, 6.0L) (* classic trucks only ) = 12582811, 12602802 = 1mb
Some of the PCM's are DBW ONLY so it is important to know what the application is.
I like to use the 1mb pcm when ever I can

hmmm... i will be using a cable driven TB... which ones are the DBW only?
Looks like :12586242, 12589463 are the 1mb ones used in both trucks and cars
Do these ECU's work right away with any of the engine combos? Like if i bought one from a 5.3L silverado would it run with out problems in the 6.0L with out tune??

You need "IAC DRIVERS INSTALLED"
2003 PCM Cable Throttle DOES WORK:
Serv. No. 12576106
Hwd. No. 12570558
2004
GTO PCM, Cable Throttle DOES WORK:
Serv. No. 12586243
Hwd. No. 12583659
2004
Silverado PCM, DOES NOT WORK with cable throttle:
Serv. No. 12586242
Hwd. No. 12593660
2005
Express PCM, Cable Throttle DOES WORK
Serv. No. 12589462
Hwd. No. 12589161
Almost every other 2005 or 2006 PCM I have seen from a Silverado, has Hwd. No. 12589162. This Hwd. No. WILL NOT work.
I did come across a 2007 Express 6.0 that had DBW. To make things confusing, its Serv. No was 12602801, but Hwd. No. was 12589161, SAME as an 05 Express PCM. Go figure...I dont know what GM is doing.
SERV. NO.- HWD NO.
12576106 - 12570558 - 2003 G-VAN, LM7, IAC DRIVERS INSTALLED. ALSO C-TRUCK LM7

im going to go with:
2004
GTO PCM, Cable Throttle DOES WORK:
Serv. No. 12586243
Hwd. No. 12583659
Is this one a 1mb one?
on ebay they list that number for both 6.0L's and 5.7's
Although my 2nd question, are they different programs/tunes?

The 99-02 camaro (warren) is DBC and works great.
CalEditor, I'm curious why you need/prefer the 1mb over the 512k. Do you run out of room? I've never heard my tuner say he's "ran out of tuning memory." Please explain.

Virtual Flexible Fuel Sensor
The Virtual Flexible Fuel Sensor algorithm replaces a sensor used to measure the concentration of ethanol in the fuel supply of the vehicle, and automatically adjusts the fuel control system to account for that concentration. This allows the sensor to be eliminated from those vehicles capable of ethanol fuel.
This innovation is being applied to flexible fuel (ethanol & gasoline) applications beginning in the 2006 model year. The Virtual Flexible Fuel Sensor allows GM to realize a savings of approximately $47M in MY2006, along with continued cost avoidance for all future ethanol applications.

These run a $350 sensor
This is a crude E85 calibration and runs on a 512kb PCM
2002 5.3L Flex 12216125.bin
These are some 1mb E85 cals. I am not sure when GM switched to The Virtual Flexible Fuel Sensor. Maybe the 06 and 07's. I remember seeing something in some of the calibrations.
