93 's came with a 4l60 not 4l60e. 94's and 95's came with 4l60e with OBD1 computer. 96 to 98 came with OBD2 computers. Cars with the OBD1 computer have shifting problems with a high stall convertor.

You could run up to a 3000 stall converter without it. More than that the sensor on the rear of the trans shifted preventing the 1-2 shift under load. Ed Wright or Bryan Herter (PCMforless)can send you a BIN file for the 1-2 Fix. TunerCat and LT1 edit are two software available for loading and tuning files. d |

The 1993 4l60's shifts are controlled by a govenor with springs and weights. The 93 computer is an EPROM chip type computer that can be reprogrammed by Ed Wright,Bryan Herter,etc.

Ed Wright on Class Racer... or Bryan Herter at bryan@pcmforless.com They are excellent and experienced tuners. Bryan sent a Bin Files for my car and it ran great. When he brought the Dyno Truck to Pocono had it Dynoed. Made tiny change which only yielded a hundredth better ET. Dan |

Anyone who wants to get a Car Classified.
Mike Baker from IHRA can send you an IHRA Technical Information Form. He just sent me a copy. May create a Database with one of my IT guys to help move the process along. They have a few already in the pot being worked over. They are earnestly busy for another month or so to finish the season. Dan |
