  • can't edit wiki, so here is the OBD1 tuning update

    Brad is out taking candy from strangers...and the site is fuxored! hahaha:P

    What equipment do I need to tune OBD1.

    ALDL Cable
    This is for any pre-1995 (OBD1) GM vehicle. Everything except the 1995 LT1. You should be able to datalog all of them, and reflash the 94 LT1 as well. Comes with XtremeALDL and NewCABL1 (RJ45/Moates-specific new style). There's a switch on the side which allows you to select 10k (across pins A&B of ALDL) or 'Open' mode. You use the 10k mode for older TBI and TPI setups, and the 'Open' for newer Speed density and LT1 stuff. This item can be used with TunerPro RT, TTS Datamaster, TunerCat reflash for LT1, WinALDL, and EFI Live V4(OBD1).


    Chip burner. Currently $85.

    Chip
    Works fine as a drop-in replacement for the AT29C256. These work great with the G1, G3, F1, etc. This is the max size for a 28-pin chip. When the C1 isn't big enough, such as Ford EEC-IV applications or later-model TBI GM systems, this chip will do the trick. 90ns flash drop-in replacement for 27C512 EPROMs. Make sure your programmer supports it, there's a funky programming erase voltage required (BURN1, APU1, or PocketProgrammer2 should be fine, APS1 is not). Works fine with 1227165, 1227730, and other similar ECMs. If your car normally takes a 27C128, 27C256, or 27C512, these should work for you. Just adjust the 'Start of Device' value when programming. (For 27C128 original, set to C000 hex. For 27C256 original, set to 8000 hex.)


    Adapter (for 1227727/1227730 style memcal chip)
    The G1 adapter bypasses your factory tuning, and lets you insert your own custom programmed chip without tearing up your stock memcal. Works with a wide range of GM chipped EFI applications, namely the 1986-1993 TPI & LT1 and the 94/95 TBI trucks.


    Freescan (scanner) for 91-93 3.4 DOHC and 91-94 3.1 VIN T

    -Use 410b file
    -set ms delay higher for slower laptops. P3-800 works well at 1. P-100 needed 50-100ms.
    -use interact

      When the wiki is up, you may add all the other options I had an email to reply to and I prefer to just update the wiki with the answers.
