okay so, if I need a new ECM anyway, what are my options?
any improvements over the original?
thanks to everyone who's been giving me advise Colorful Colorado now includes Black Rose Metallic! ESR RF02 WHEELS 18x9 / 18x10 in Hyper Black Toyo Proxes T1 Sport 275 35 18 / 295 35 18 tires
AFAIK there is no upgrades for the 92-93 speed density ECM. You could upgrade to SFI with 94-95 wiring harness and PCM oem would require adding MAF with relate ducts or custom reprogramming to keep speed density. Other option is stand alone and adapting it to car.
How much re-wiring are you willing to do? What is your goal with the new system (Do you own tuning, self learning, be LS Based, etc.)? That may determine what the recommendations are.
I am using Dynamic EFI's EBL on my TPI. I like it so far. It basically turns the factory ECM into a flash based ECM running the same logic. Not sure if this works on the 92LT1s or not.
ECM UPGRADE? 93 base
