Pure Stage 1 - JB4 Map 6 Settings

sd306 · 02-17-2017, 10:21 AM

At 100% e85 (tested and verified ethanol percentage) pure stage 1, fuel-it throttle body injection, fuel-it stage 2 lpfp, ngk plugs

Just posting if someone doesn't know where to start for jb4 settings. This is maxed out for me. I have BEF for port injection from BMS on cobb.

The center column (fuel bias) has 0 effect in my setup so disregard those numbers.

Why not replace the Tmap and run more boost in the mid range?

I have the n20 tmap. If I run more boost the average ign goes up past 2.0 and fuel pump chokes at 23psi i think

I can try upping the boost from 3k-5k again and see

At a minimum I would have full boost come on at 3,000 rpm, even if you decide to only run 20 psi.
