Best jb4 map for e85/91 mix - BMW 3-Series (E90 E92) Forum

bmw335idizzle · 11-08-2012, 05:32 PM

Just wondering which jb4 map is best to use for max whp gains when running e85/91 mix. I'm thinking of 70/30 91:ethanol. I keep seeing people run all types of maps but which one is best?

I run map 5 on my 93/E85 mix of about 1/3 E85. Pulls strong.

running dci, jb4, 40% e85 on map 5. Make sure you have the latest firmware and your golden.

agree with above, I run 30 e 85 and 70 93 on the newest firmware which seems loads better for ethanol. Map 5 does great

GTstunna612 · 11-08-2012, 10:30 PM

any new firmware updates for jb4?

Eracer76 · 11-09-2012, 10:51 AM

I run Map5 also and I've been running 50/50 E85/93 for about 6 months with no problems... every update just keeps getting better, I'm currently on the G5 ISO 11C and its great! Then when I want another extra kick, I switch over to Map3

not right now.....seems as tho Terry is working on the G5 mostly right now. But he did state that any new firmware for the G5 that can be used on the JB4 will be passed down.

Looks like map 5 is the best way to go. How do I download the latest firmware?

No idea. But the butt dyno tells me that it feels just as strong, if not stronger, as the car did when I ran it at the 1/4 mile track on 100 octane, on older JB4 firmware. I ran a 12.519 @ 112.77 on that day (really hot in humid, mid summer in south Florida).

Upload firmware and select the hex file you downloaded from n54tech.

Map 5 is weak compared to map 2 when running around 6.5 gallons of E-85. I've tested both and map 2 is the stronger map.

I see people say this but the dyno proved otherwise for me.
