    is there anyone out there that is still messing with the 96-97 swap to 98-99 black box or the 411?

    i would like to get my hands on the pin out for the 96 to try the swap.

    I just did a 97 to 0411, 96 should be the same. I can tune the 96 pcm though. Why do you want to make the switch

    I don't have my GMT400 anymore, but I know I downloaded the pin outs in spreadsheet form at one time and I think it was from this forum. I looked and I don't have the pin outs anymore.

    all you will really find is to email that lex guy. that's about all I ever found about doing the swap. I've been tuning cars since the old prom days to the new ish stuff, so I think I have a bit of an understanding of what's needed. I emailed him, ask a few questions, got replies that made no sense. I replied back to him that I read you can sell me a ecm with a starting point flashed on it, so I don't have to worry about the tranny side. the reply I got was him basically blowing me off and he didn't seem to want to sell me anything. so I gave up. he didn't seem to want to be bothered by this internet always listing his name everywhere. I mean if I had something wrong. he could have just told me what I needed, gave me a price and I'd have paid it to avoid the junk yard hassle and starting from a bad base.

    hope you have better luck than me.

    I've done a couple swaps havnt needed yet to do a 411 swap I've always installed a 98-99 black box you have to pin 1-2 injectors at the ecm. Turn vats off and tune. Both I've done have been 454 I just start with a 454 black box. Or 5.7l if that's what your tuning.

    Sounds exactly like the experience i had with him, i can't understand hoarding the spreadsheets privately and making a big post about how awesome you are for figuring this out and then not responding to anyone who actually wants to use your "holy than thou" pinout spreadsheet.

    I gave up on getting any information out of that dude. Its a lost cause. So ive been working on my own conversion spreadsheet for 1997 5.7 liter PCM to 2002 0411 PCM going pin by pin which i plan to make publicly available on this forum when its complete so no one has to go through hoops trying to get intouch with the unresponsive lextech.

    I will say the hardest part of the swap isn't the repining but the the different configurations these trucks had from the factory. Case ground vs isolated ground o2 sensors for example can throw you off as well as anything to do with EGR, EVAP, and a few other little things that were controlled differently on certain trucks.

    If you want to do this swap you better be good at reading wiring diagrams and know your way around a multimeter

    any luck on that pinout? I got this one from a 01 blazer http://www.ppepower.com/forum/viewtopic.php?t=10180 and AutoZone has some wiring diagrams that are good https://www.autozone.com/repairinfo/...96b43f80371563. I just did my swap but having issues with no speedo and trans wont shift, also trying to get a hold of LEX but no luck.

    Still having issues?

    I did the 411 swap on a 1997 5.7 with a black box about a year ago. I ordered the 411, plugs, and spreadsheet off ebay for like $150. The spreadsheet was dead on, and he loaded the Express Van base tune, as well as disabled VATS and a few other items (This was before I had HPT). It was a simple swap, just a little tedious moving pins. At the time, I was running a 700r4 as this is in a 1983 K5 Blazer. I have since swapped to a 1999 4L60e. Added VSS, Cam, headers, etc.

    The 411 alone made the engine run way better and more crisp throttle response.

    4L60e requires VSS to the PCM to shift out of 1st gear. PCM doesn't "need" VSS to run properly, but certain aspects work better with VSS. Coasting, idle in and out of gear, etc.

    Here is the spread sheet.

    I am hoping that the early 1996-97 are supported in the near future also. I got the 1996 0411 swap spreadsheet through another source after I experienced the same sort of run around others did. I see his point too, but I think not releasing the info publicly is costing him a lot of time each week on just bs requests for the information. The 1996 to 0411 spread sheet says the evap system must be disabled or a later canister and pressure sensor must be swapped in. Some parts of my state still have very strict screening for emissions. Yes, I could pull the evap system from a 98, but at this point I would rather just be able to mess with the original black box and would gladly buy the credits to do it even if it was more than the LSx. There are also wires that have to be spliced and added for 96. I guess the 1998 and up are an easier swap, more a repin. There are a lot of threads on the internet for people looking to use what they have with the 1996/97 trucks. Some even mention a "Road Runner" to program it, its $1700! I also know a person who worked in GM vcm calibration. He says the black boxes actually have a better pressure profile for the 4l80e than the newer pcms, because of a staff change after 98. The new guy did soften the shifts up and durably suffered a little. While it can be changed, I would rather just start from the base my l29 had originally. The same person has a "copy" of the software that was used to prototype the calibrations pre-production on the early black boxes, but he says its not user friendly, runs only on XP and is not explained. He can use it, as he is trained, but people like myself would probably mess things up. That's my pitch, just hoping that someone official takes a harder look at taking the 1996-1997 vortec truck owners money after 8 years of posts.

    411 swap is the way to go. It cheap, easy, and will make an instant improvement. If you can?t find a spreadsheet to do all the thinking for you, you can find pinouts online and make your own cross reference spreadsheet.

    The swap was absolutely worth while. I use my 83 K5 as a DD and road trip vehicle.

    Before I order my ?kit? on eBay, I did some research, and you can find the pinouts online. You could easily make your own spreadsheet with a couple hours of google time, especially when I?ve already posted the spreadsheet I used as a starting point, and the 96 to 97 engines are the same.

    My 1997 had the black box, and a painless harness when I got it. The wiring color codes matched factory and it was a simple process. I spent more time organizing individual wires before inserting the pins just to make it look good, and building mounting brackets. Even at that, it was a 2 hour job max.
