    larger throttle body tuning

    I tried searching, but I'm not coming up with an answer to my issue. I have a 99 TAHOE with a 5.7L vortec, 0411 PCM swap running an 02 OS, dual electric fans, Camaro segment swap(modified the request...

    For LML EVERY segment MUST match perfectly or else you WILL have problems.

    I have 2 cab & chassis tune files, but neither one has the fuel system segment's mapped out. The H&S probably doesn't have a dual tank fuel system segment in it which would cause your issue because...

    I would start by swapping in a 02 LM7 engine segment. There's alot more changes than just VE and cylinder volume between an LS1 and LM7. Then I would be checking your wiring for your O2 heaters. The...

    You might could try the 98 ls1a pcm to see if that works. I use my tech 2, so I don't know about efilive doing it. I do know externally 96/97 looks the same as 98-00, but internally they're...

    I found a list online of a company auctioning off trucks and it had vin numbers listed. That was how I found the 01. From what I've found, 1500's were 4.3's, 2500's were still 6 lug, but had the 5.7l...

    I know most just use the van OS, but here's an 01 L31 manual trans from a GMT-800 truck out of Mexico. I'm still on the hunt for an 02 to compare to the 02 van OS. I did see quite a bit of difference...

    If you want to tune an L31, the 1st step I would reccomend is an 0411 swap(unless you're tuning an 01/02 van that already has one). The 96/97 pcm is only tuneable by 2 programs I believe, 1 is no...

    If you can get me a VIN number of what you're looking for, I can flash either an 0411 or my 1mb for you with my TECH2, and read it back out with my V2. And FYI, there was never a pickup tune with an...

    The injectors did change, but it's not a big change. You could have just as easily have loaded the 1256 02 os into your 99 pcm. You can disable vats, or do a vats relearn, and run the 02 as is, but I...

    Seed key/unlocking

    Does the seed key get altered/changed even if locking isn't selected? I'm trying to get the .bin file out of my 0411 PCM to make some changes and I'm getting a locked message.

    For idle and off idle the calculator doesn't work. Your going to have to work with it until you find what it likes. Your going to need to increase pressure at idle. But my experience has been pilot...

    All of them I'm looking at are bosch 4.9 sensors. I had read serial was better than analog for datalogging, so that's why I was wanting to get one that had a serial port. It's new to me to need...

    Do you have a V2 to flash in tunes, or are you looking for a tuner. I'm guessing you currently have longhorn since you said it has a smoke tune, and that's there signature tune. If you have a V2,...

    You might want to look at an 02 3500hd. They were still the older gmt-400, but had the 8.1l in them as GM discontinued the 7.4l in 00. I don't know if they were dbw or dbc, but I think they switched...

    Pretty sure the LQ9 came out in 02 with the 0411 red/blue pcm. Heres a copy of an 02 LQ9 file on dropbox. It is a DBW tune, so I wouldn't segment swap, just compare and swap.
