JB4 install first impressions

Took the plunge and installed my JB4 last Wednesday (while g/f was putting up my roof Xmas lights - now that's dedication). The install required the video and the hard copy instructions. It took me 2.5 hours, although I took my time to make SURE I got it right the first time. I can honestly say it should be about 45 min next time. It's kind of scary digging into the guts of the DME.

I wanted to try Map 5 with a blend of 40% E85 (which is available less than 5 miles away) and 60% 91 octane, but I ran out of time. I ran on Map 1 and Map 5 and didn't notice much difference running straight 91. I logged about 400 miles on a long weekend trip and I gotta say I'm very happy with the results. First time on WOT, I saw DTC lights and heard tires chirpping Power delivery is smooth and strong to redline.

I'll report back when I get some E85 in her and autotune on Map 5.

Any reason to not just clear codes and leave JB4 in for routine trips to dealer (I'm CPO for next two years)?

You cant leave the Jb4 on anything but map 0 if you plan on leaving it in for dealer visits due to the fact that the JB4 disables the obd port.

Yeah, I would set it to map 0, but I'm asking about physically leaving it installed so I don't have to mess with removal/reinstall each time I visit dealer.

Obviously if I have something related to turbos, DME, etc. when I bring it in I would remove JB4.

Glad the install went ok. Installing a piggy can be intimidating the first time. Now i could do it with my eyes closed. For oil changes or warranty work totally unrelated to the motor it's fine. I've left my procede in for such things with no issues.

What JB4 do you have? G5 or G4? You are going to LOVE the E85. You won't see much more boost if any on CA 91 and Map 5. With Map 5 and E85 set your boost limit to 18psi and you should be able to peg that with a 40-50 mix and perfect timing. When you need more, think about a DCI and an FMIC.

My JB4 G5 is on it's way. Already have DCI installed.
When can I start pumping in E85/93 Octane blend to run map5?
Also how do you exactly know the mixture percentage? Is this eye balling it from total volume of the tank?

You can run E85 with no other mods on map 5. Assume 16 gallons in tank. I fill 8ga E85 and then the remainder with 91 and then reset the Map (do this by selecting a different map and then switching back to Map 5). Have fun!

I would say take it out when you go to the dealer just to be safe. After a few more times installing and uninstalling it you'll be able to get it all done with no instructions and in 15 minutes. My first install also took around 2.5 hours and I followed the video and printed instructions. I can now do it in 10-15 minutes max including the USB install into the glove box

That’s interesting my car pulls much stronger on pure 100oct and map 7
then E85 mix on map5 which I only get about 13-14 psi
I guess time for me to do some logging. Add more E85 maybe?

Which firmware version? There were really big changes to the Map 5 within the last 6 months. I think even Map 7 has been changed to be more aggressive (19 psi iirc).

You probably need to re-adapt the car. Map 5 will run conservative boost until you do at least three WOT runs in 3rd gear, throughout the rpm range. I reccomend at least E20 for there to be a difference.

I recently installed the G5 board and I love it. I am only running DCI and going from G4 to G5 is a big difference. The smoothness in daily driving is much better, and the car pulls much harder as map5 adapts more and more.

JB4 + G5 installation completed!

I can definitely feel the difference and that's before mixing E85! After installation, I took it for a test drive with map5... (I have BMS DCI only)
first few WOT runs were very impressive until car jerked and threw a code at me. 29F2 - Fuel Pressure....!! I pulled over and searched for the code immediately and found out it was a common issue. I guess running map 5 with no E85 mixed is too much...?
But I was told that you can run map 5 with no mods... ??
So I switched to map1 restarted the car and did few more WOT runs and no codes.
(Keep in mind that I have less than 1000 miles on my 335is so bad fuel pressure is not likely the case...)

I'm confused though... I thought G5 was suppose to fix minor code issues..?
Oh and also, when I start up JB4 interface on my computer it does say, "interface settings does not match G5 board"
Was I suppose to update the firmware?

Please advise!

Are you running ISO? Update the interface (software) and the firmware to latest version. I don't know about that code, but I'd keep driving and if it pops up again email Terry. If not, it may just be adaptation tbh. I have had weird stuff pop up once when I switch big things. You can run Map 5 on 91 only no problem. That code doesn't have anything to do with that.

Post and read up on here and most of your questions will be answered. I only have DCI as well, but I have not gotten that code. I have done a few pulls myself, and it seems to get better every time. Only thing is when the car is cold, it shifts a bit rough. After warming up it gets better.
