Checked what map I was in and the JB4 said "invalid nap selection" and it magically ended up on Map 1. But when I checked the logs while this was happening it says I was still in Map 6. I had to pull over, restart the car, clear the codes, and switch back to Map 6.

Anyone got any thoughts on this?
This happened to me again twice today during my commute. This time I'm on EWG_15_T5B firmware. The worst part is it disconnects my tablet from the JB4 and I was not able to reconnect.

Terry any help with this?

Not had any reports of it, but I think it's a flash issue. Are you using our off the shelf BEF map or did you modify it?

Using a modified version of your BEF. I can send it to you. But all I've changed is fuel, timing, and fuel scalar.

I had this same thing happen to me feels like you hit a wall really scary. It was the fuel scalars on a modified flash ****ed up something about the fuel mass vs load that the dme didn’t like. I would leave scalars alone use the jb4 e85 or pump scalars

Seriously? So you can't tune the fuel scalars? How did you figure that out?

You can hange them but if you go to far you get these hard core shutdowns. When I changed back to bms bef it was normal again

That doesn’t explain the JB4 switching to an invalid map.

No it doesn’t I just wanted to share when this happened to me and the cause. It was scary, repeatable and very little online for help

So I think I finally got spool up to the perfect spot. I used some WGDC tables from Jeff and now I'm seeing 19.6psi br 3500rpm and 22.4psi by 3725rpm. Prior to this I was lucky to see 20psi by 4000-4100rpm. That's a hell of an improvement. Next step is to dial in the over boosting that's happening. I am so glad I went with the 8374.

looks good, but u should see a good tuner to fully tune ur setup not just modefy few tables, also it will spool faster.

any vbox test 100-200km, 60-130mph?

I donít want it to spool faster. Almost 20psi by 3500 is plenty fast. Iím still having throttle closures in 5th so no crazy pulls.

Did you change scalars? What changed helped he shut down?

I did. I also lowered load back to 160 in the BEF and used the correct XDF. I think I was using a different one than the one BMS supplied.

Both could have effected it. If your using Jeff’s flash it has a ramped load ceiling curve. There’s some benefit to running the bms load ceilings if using jb4. Idk wtf the scalars did that to my car because trim and hpfp was fine there something in the dme that flips out. I’ve been good just running the standard bms bef but I understand about spoiling. Mine spools faster than yours being 7670 but I don’t want lightning spool either. looking very impressive I hope you make me regret not getting the 8k series

This freaking car moves! It feels like a complete beast at 25psi. The only issue I'm running into now is I'm having a major throttle closure in 5th. The car hesitates dramatically at any psi at WOT shifting into 5th. Could it be a torque limiter?

First log is 23psi and second one is 25psi. You can see the 5th gear throttle closure in both logs.

You should be able to pick up a little more power if you lean it out a little bit more. Looks good though. Congrats!

Set open loop to 0. I wonder if you are hitting a limiter of some sort in 5th only. Other than that it looks really good.

Set FOL to zero? What will that do?

It definitely feels like a limiter.

Your fuel trims are negative you are getting too much fuel. Lowering the FOL will help trims. If that doesn't help much you will have to lower your fuel bias.

I'm still getting an initial trim spike on spool up. I was planning on lowering the PI fuel bias by 10 and going from there. But if you think I should drop FOL to zero I'll try that.

Have you modified your load ceiling? I see you are lower than typical BEF? Can you send me your bin please?

The load target in the BMS BEF is 160 across the board.
