Hey all! Just joined the forum to hopefully be able to learn about the GM TBI FI system in my 1990 K2500 and get the most out of it! Last year I swapped in 383 replacement engine that was designed to utilize the stock TBI system. It has ran pretty well, but I think it can be better. I'm only getting into logging data right now, but I hope to be able to understand what the data is saying and be able to improve it on my own!
Depending on how busy I am, I can sometimes help with a posted data log. Other members have also helped with posted data logs.

I just posted a data log in the GM TBI section. I'm really looking forward to learning about how powerful this data is. I have no idea what kind of program is on the new chip that came with the motor, but I'm sure it can be read and saved to be modified if needed.
1990 Chevrolet K2500, RCLB, Blueprint 383 TBI (16197427 ECM / 61 lb/hr / 16 psi FP), NV4500, NP241C, 4.10
