Joe, is there a reason not to use Lambda?
First, the LS2 OEM injector is not 46lb/hr, so the table for that injector will not translate for your FAST injectors. The LS2 is approx 33 lb/hr. Second, you don't say anything about having a...

Well, something is amiss. My scan tool doesn't see my wideband in analog form either.
I have my V2 communicating with my LM-2 serial cable. I can see lambda on the V2. However, my scan tool isn't seeing the serial input. Looking at the tutorial one is suppose to drag & drop the...
I'll be making some comparo's here soon. I have a Wideband Commander, LM-2, and now i have a new TechEdge 2J9 & LSU 4.9 sensor. As far as being out of whack, GM uses the same injector in multiple...
No. SSpdDmon had been playing with assuming the oem MAF values were correct and adjusting IFR to get AFR correct. He was just running pure MAF. I'd prefer to use both theMAF and VE table.
I see this same thing happening with one of my cars. At idle, my AFR is lean according to my wideband(s) and my trims are removing fuel (-20). B4105 (O2 Switch Point) all set to 450. Might the...
Actually, after thinking about it, this makes sense. What I have thought was correct may well be incorrect. That calibration must be taking into account some air coming either around the TB blade...
The Corvette is a different animal. I have an '04 and if anything electrical changes during the PCM flash, stuff goes nuts. I make certain everything is turned off except the ignition key when I'm...
OK. It's a Molex micro-fit receptacle that's required. #43025-0400
You need to know more than I know to do a proper search. I tried to identify the molex plug that connects to the LC-1, LM-2, but I could not find it after searching for it for quite a while. I...
Surely we have a forum member that knows where the stuff can be sourced to make a cable. The cable I have only uses 3 of four poles coming from the serial output to the EFILive RS232 plug.
Isn't...
IAC effective area does not change on a cable throttle body. You use the same idle air control valve on the 90mm TB that you used on the 78mm TB. It opens the same amount for the IAC counts and...
The Corvette is finnicky. I don't have any issues reflashing my '04 Z06 so long as I make certain everything is turned off before I begin the flash. Do not turn anything on or roll a window up/down...
I.m guessing you have a vacuum leak somewhere. 73kPa at idle is way too high for your cam. You should be in the vicinity of 45 to 50kPa. My G5x3 idles at 50-55 kPa. In addition, something is...
Go to the first post and at the bottom of that post is a link to download the CALC.VET Tuning Tutorial. Under Item #3 at the top of the page in bold lettters is:

Wouldn't the LS9 be a better starting point for you? The link you gave is a low compression crate ready for boost. That's what the LS9 is.
There is a 2009 ZR1 oem tune @ Holden Crazy.
I thought maybe you were boosted based on the big assed injectors. But I see you have a 402. What are they, 65 lbs/hr?
Anyhow, you're dumping fuel at it because your VE table is way too high...
I'm no expert but here's what I see.
I'm guessing your IAT really isn't -39*C.
There's nothing coming from the MAF?
Your o2 sensors are reading 900+. They ought to be around 450-500mv...
You shouldn't have to drill a hole. If you think you need more idle air, increase that, but don't drill.
Done & glad I could help out.
Man O Man. Hard to believe.
This has been pointed out in the past when someone insists there's only one way or one right way to skin this cat.
