    Learning curve

    Hi, I have to learn to tune.
    1992 Blazer K1500 4x4, fresh 5 speed conversion, fresh 6.2L 1pc seal, RamJet cam, Vortec heads, 1416299 ECM, 1.930" TBI, 65# INJ, Tri-y single, high flow cat, second bung with Innovate WB MTX-L .
    Old school SBC carb guy, I've been using pre-burned chips, need to pick/try directions, I'm seeing tons of good information here, getting hopeful I will be able to keep GM ECM.

    The first place I recommend starting the "Tune" learning process is to come up to speed data logging with TunerPro RT. Attached are TunerPro RT .adx and .xdf files. I also attached a stock .bin file (5.7 liter / 700R4) Broad Cast Code (BCC) AWLB.

    Thx.
    I need to get a usb/serial converter, I have the serial/aldl cable, I'll give it a try. I captured some logs a while back when the previous 383 engine was in there, but the data didn't mean anything to me, I don't remember which program I used.
    I'll grab those files, I have no idea how to plug updated files into the chip, first things first like you say, log data.
    Also I'm not finished installing MTX-L and don't know how to pull data from it and aldl at the same time to make use of it, at least I'll be able to look at it while driving and know real-time where AFR is off.

    I'm not a huge fan of the 1614299 ECM. It's not well supported. If it was my vehicle, I would upgrade the 16197427 PCM http://www.gearhead-efi.com/Fuel-Inj...Information-0D and http://www.gearhead-efi.com/Fuel-Inj...st-impressions

    The 16197427 PCM is normally used for either 4L60E or 4L80E, but can be set up for manual trans or non-electronic trans (700R4, TH350, TH400). The MTX-L AFR information can be configured for real time WBO2 into the 16197427 data log. The 16197427 is affordable and supported much better than the 1614299 ECM! I've made plug-n-play adapters to convert from the 1614299 ECM to 16197427 PCM.

    There is a fairly complete hack and matching XDF floating around that I use to tune them. I much prefer the 299 to the 7747. The 7427 is a better unit than the 7747 or 299.

    That being said the 299 is VERY EASY to tune, easier than a 7747 IMO.

    thanks for the feedback, I have 2 299s and I think a 7747, and one from a 1989 stick vehicle. I'll look into 7427 availability.
