I dint have any traction loss I know for a fact super dry pavement sticky tires, and you could feel the car hook up nicley it just shifted almost right away under load around 3 to 4k rpm ill note it happened also from 2nd to 3rd gear too.
I have had loss of traction a few times before and the car dint shift early any of the times.

weird I hope its not a major problem.
for me it always happens at ~5500RPM.

Red is stock boost and blue is tuned boost. Should be a good bit quicker than stock... Map 2 will probably be more to your liking though.

The JB4 can't effect shift behavior directly. Short shifting is the result of the DME perceiving wheel spin and shifting up to the next gear as a result. You should be shifting N55s around 5700rpm anyway for optimal acceleration. Sounds like it's doing you a favor.

Thanks very much!

Got a quick map 2 log in this morning. 93 octane only. Seems to pull a tad harder than map 1 but not much according to the butt dyno. Maybe it's just placebo effect, who knows, lol.

You're hitting 15lbs of boost which is nice

So, tested the 3.3 a little bit more! I got a lot of Drive Train Errors on the dash! Back to 3.2 no Problems! Seems there must be something wrong here!!l

Attached is a second log of map 2.

Seems like I'm only hitting the 15-15.5 psi in 5th gear. Back when I had a FBO N54, the only gear that wouldn't hit target was 1st and sometimes 2nd.

I'm thinking that maybe the combination of the stock turbo and the shorter gears in the 8AT transmission just doesn't allow the turbo to load up enough to hit the targets. I could be wrong, maybe Terry could comment on this.

Not sure if it's a N55 JB4 User/Interface thing or not but the "Target" logging PID seems way low. Anybody know what's up with the target PID?

Torben,

Do you have the EWG specific board, Flex fuel wires, and EWG wires??

Hi Nick,

yes the EWG wires and Flex fuel but not the EWG upgrade board. Only the normal one! Put JB4 to Map 0 everything works fine! Onyl in Map 1 and 2. With 3.0 and 3.2 no Problems!!!

No known issues. So next time be sure to read the fault. Probably just a setting on your setup.

I think I saw this same log in the support section. Which is where all logs should go. But looks basically on target to me. In lower gears you'll have less boost especially with additive maps like the new map 1 and map 2 because the DME has a lower target there & since duty cycle is being run by the DME it takes some time for EGT to get up high enough to allow the car to hit those higher targets.

Makes perfect sense Terry. Thanks for taking the time to explain it

Yeah, it does seem a bit weird. I'm use to the way the older maps worked by targeting a set psi regardless of what the DME is targeting.

Not sure if I missed it somewhere or not but how is the BMS FSB wired when running a EWG board, FF, and EWG connectors?

It's in the EWG specific thread. But the blue wire goes to DB9#9 (data cable) instead of DB25#16 (JB4 main connector).

I am not seeing the install guide for the BMS Stage 1 N55 install.

For the MAP sensor, should the brown or purple harness be connected?

The F30 instructions (only one I can find) says brown; however, the purple fits perfectly. Brown doesn't snap in as OEM.

You must have the wrong harness type then.

Why the change to additive maps? Sorry if there was an explanation somewhere but I couldn't find any more info on the change other then what's in the first post.

Thanks! Very helpful. I couldn't find this on the BMS guide site.

Terry, I believe I have the correct harness type (A) for my 2011 F10 n55. It is odd that the style of connector for my TMAP is A, but my MAP is B. The brown harness will not fit for my MAP. The purple harness does fit perfectly. Should I not install this? Oddly enough, I used this tune for a year before I removed it a few months ago for dealer work. I must have had the purple connected for the MAP before. No issues.

Unfortunately the instructions posted does not mention what color harness to use for the MAP. By elimination it would be brown because the purple was said to be unused.

Terry, just to confirm how the FSB should be wired for peeps that are running the EWG board, FF, and EWG wires.

Blue FSB wire to DB9 position #9
Orange FSB wire to DB25 position #3
Green FSB wire to solenoid ground wire
Black FSB wire to chassis ground / shock tower
Red FSB power wire to under hood 12V post
Red(thick) FSB to pump and solenoid power wires

Is this correct?

Feel free to post photos in the support section. You've mistaken your MAF for your MAP. The MAF uses a "type B" style connector but should not be touched as its not used for the JB4 installation. TMAP and MAP always use the same connector. Should be TypeA for a 2010.

Sounds right to me. The FSB RED wire on the same side as the ground is the +12v. while the other one goes to the pump & solenoid.
