    HP Tuners

    Cool, I will have to pick up a 411 box and connectors next time out.

    HP Tuners

    I guess from the reading I've done and the segment swap talk and such I just figured it would be easier to have the computer with the "right" architecture to start. I have the 99 7.4/4l80e and 4x4 so there is a bunch there to fool with to get the thing to work. I've come on several 411 boxes at...

    HP Tuners

    We have the hptuners. Handy as we have several gm vehicles that it can be used on. My son bought it to tune his sc3800 swap into a fiero. I used it to disable the vats on our 99 suburban and 03 cavalier. And we have a 2000 Malibu if that vats gets acting up it'll get the axe too. Downside is in...

    Trans issue after 0411 PCM Swap

    If you move the lever down to 2nd and first, does the trans down shift? You say it was rebuilt, but a "lesser" quality shop might not have replaced the shift solenoids and electrical stuff on the vb and when it heats up it causes probs. What are you doing to get it to down shift, then when you...

    cam options?

    Are you planning a 411 swap or staying with the "black box"? Either will require a retune when going to a "larger" cam but the 411 gives the ability to be more precise as it has more tables to tune with and a faster processor.

    When my GMT400 isn't enough...

    It is a nice looking truck in the pix. I have a 1994 half ton in that color combo. Might be worth $8k to someone, but not me.

    When my GMT400 isn't enough...

    Depends on what we bring along and where we go. Mostly it goes to the drag strip with our car in it. I bought the 28' thinking i would fit a junior dragster or golf cart in front of the car. Neither of those materialized. It has moved us to Wisconsin, and back to dfw, then to houston, then...

    New to me project truck, need help with transmission and other questions

    Is it using the "black box" computer? or something else? I would be hunting a trouble shooting tree for that 96 stuff and see where it leads you with the trans not shifting. Look for a 96 service manual, I would think someone has it hosted online somewhere.

    When my GMT400 isn't enough...

    No doubt tire failure is a conundrum. This is where the sway control and weight distribution hitch are worth the money. I come from further back starting with an 83 454/th400/4.10 suburban pulling our toy box. Single digit mpg was the rule and even unloaded around town getting 10 was something...

    NP246 Autotrak in a K1500 99 Suburban..... is this bad news, good news, or wha?

    Pix of the hole(fixed with some jb weld), the pieces that were in there, the special pump half with the "feet" to prevent the pump rub, and the big bearing with no ball separators they I guess melted out as there were just gone. And not sure if you "need" the autotrack II fluid(smurf fluid as...

    NP246 Autotrak in a K1500 99 Suburban..... is this bad news, good news, or wha?

    I did an over haul on the np246 when ours leaked all the fluid out due to the pump rub issue(and pretty much ate itself up inside). I had bought another np246 out of a half ton. As mentioned above the half ton is a 27 spline while the 2500 with the 4l80e is 32 spline. These are...

    12200411 PCM swap for 1996 to 2000 GMT400 trucks

    Y'all are full of info. Thanks SO much for sharing! I'm going to the wrecking yard in the am if it doesn't rain. The yard we are going to has an 02 express van on their inventory listed on the website. I hope the 411 is there and I can get the red and blue connectors. We are also hunting...

    12200411 PCM swap for 1996 to 2000 GMT400 trucks

    This vid talks of having to license if you want to be able to modify and rewrite. Devin Taylor I guess had the license to his 411 box so he was able to write to it. Im not sure exactly as they(hptuners) are so cryptic about it and steady have the pop up to try to get you to license. Either way...

    12200411 PCM swap for 1996 to 2000 GMT400 trucks

    We have emission testing until the vehicle is 25 yrs old in the county I'm in(deemed a high emission county by the state). This is a 99 so only a few more yrs until safety only annual inspection unless the laws change. I have a line on what is purported to be an 02 express van 411. Is there a...

    12200411 PCM swap for 1996 to 2000 GMT400 trucks

    All right, I've been poking around in the vcm editor and came up with these instructions for changing the vin through the help section tips and tricks. The last 3 lines is where I believe you are right about the needing two licenses, one for old vin/box and one for new vin/tune to be loaded. I...
