93 Corvette / Camaro LT1 16159278

Introduction

The 1993 Camaro / Corvette LT1 PCM 16159278 is an oddball.  It was not used before or since.  The $DA2 mask was used in Y-body Corvettes and the $DA3 mask was used in F-body Camaro/Firebirds.

Hardware for Tuning

  • G1 Chip adapter and C2 27SF512 chip required to reprogram ECM
  • BURN2 Chip Programmer programs 27SF512 chips
  • ALDU1 with CABL1 required for datalogging
  • Ostrich2 required for real time tuning
  • APU1 AutoPROM All-in-one device works great, taking the place of BURN2, ALDU1+CABL1 and Ostrich2

Software for Tuning

Recommended Hardware to Buy

  1. G1 + BURN2 + C2 = most basic
  2. G1 + BURN2 + C2 + ALDU1 w/ CABL1 = basic with logging capabilities
  3. G1 + APU1 = Chip tune / realtime tune / datalog – full capabilities
  4. G1 + APU1 + MTX-L = full capabilites with wideband logging
