    400 SBC Tune

    Greetings! I wanted to get some ecm ninja's to take a look at the Bin I am running on my 400 SBC. Runs really good but I think there may be some room for improvement. Application: 1989 5.7 wiring harness and TBI (i know i know 454 TBI would probably work better but im not made of gold). High rise intake, full headers, A/C and 3 speed T350 Transmission. All stock sensors and O2. I am running a 27fs512 chip using a Burn2 programmer. Thanks!

    I do not have a logger setup at the moment. I plan to make my own adapter for this info. Obviously with that info would come a more precise tune, I wanted to be sure obvious parameters weren't overlooked related due to the 50 extra cubes, etc. (Heated o2 btw)

    Yes, the tune will be more precise. See attached data log pics.

    nice, I guess I need to bust out my solder gun and attempt the home made cable..I was reading where the displacement was defined in the bin but I didnt find a reference unless it is called something completely different. I was trying to get some of the obvious snafu's.
