E85 Tested (JB4 Stage 2)

Alan l. · 10-10-2012, 10:27 AM

Did you notice more lag at 4.5? I was going through some old posts and some people said the car felt the fastest at 4 and the higher they went the more laggy it felt.

I am reaching here. But it could be an issue because you are tapped into the canbus. I had the cantool for my E60 and if I left it plugged into the port overnight I would get a low battery error.... Was this an issue when you had stage 1? Or only now that you have upgraded to stage 2.

Were those people in a state that suffered from the dreaded limits of 91 octane instead of 93?
I hopped straight into 4.5, I didn't test any other settings so I truely couldn't tell you if there was any difference.

It's only happened with stage 2 so it's probably the canbus

I'm starting this thread up again. I recently ordered the Flex Fuel wires from terry and am going to start running E85 again. Hoping for some noticeable power gains. Has anyone got the flex fuel wires?

Nice car man, i recently installed the flex fuel wires onto my jb4 stage2. The gains are deffinetly noticeable, it took me about a good 50 miles to feel the difference. Although after filling a couple of full tanks now i can say the gains are much more noticeable now, its been two weeks.
