Hello,

I am still learning the JB4 and have searched for this but cannot find a definitive answer. I have the Flex Fuel wires installed. What should this value be set at? The Flex Fuel wire installation says 50 and the default for ISO (which I am running) is 70. So, I would assume 50. I have the N55.

To throw another wrench in I have the Fuel-It Stage 2 LPFP.

Thanks! Also if you want to post a picture of your custom settings and map 6 for the Jb4 that would be awesome.

Put it at 70 since you're ISO. If you start maxing your trims out with E85 raise it up to 80. I know some guys have it set to 90 depending on their vehicle and how healthy it runs.

Thank you, it's at 70 now. I will log and revise!

Yup, mine's at 90, and trims look good (running E30 on map 5). Was told not to exceed 90 or I'll start throwing codes.
