Very impressive #'s! This is the best of my JB4 only runs on Map 6. Was running around E40 blend.

Anyone having post shift boost issues? 3rd gear and 4th gear logs i can hit 20psi boost no problem. Doing 2-3-4 though I only get like 14psi. Stock turbo

[Mikaeldarer]

Just got a baseline log back to back with current custom 93 oct tune revision. Very happy with how things are looking and can't wait to see where we get on the E50 tune!

I took a 3rd gear log today and plugged it into VD. This is in map 5/e85 flash with around E40.

Johnny,

Do you have a gear to gear (like 2-3-4) CSV using the latest firmware and maps?

I can boost 20+ PSI in 3rd or 4th gear, but once I start shifting I loose 4-6psi that never comes back.

Terry thinks it's my DV but I didn't have this issue two maps ago. And we have similar cars...

Here's a log shifting from 2nd into 3rd gear. I let off after I shifted into 4th.

fuel and boost all over the place

I was testing a flash from Terry. I will work back with him to figure out what's going on. Thanks for the feedback.

I was thinking the same thing.

Thanks guys. I have flashed back to the previous map for now. I will be putting in straight 93 octane and logging that this weekend.

For right now I can put out more power with the JB4 because:
1) stage 2 maps not out for MHD yet
2) timing is a bit more aggressive on the BEF than the OTS tunes from MHD
3) meth control (but any controller can do this of course)

I plan to keep things stacked and optimise my own BEF as every car will be different.
I will also unstack jb4 and try MHD stage 2 and 2+ when it is available. to compare to my custom maps.

Either way, both are great products individually or stacked! Keeping them stacked allows more flexibility and some extra safeties on the jb4.

How did you disconnect JB4 when testing MHD OTS only? Keep us updated on further testing comparing the two options, thanks!

You have to completely remove JB4 to run MHD only

Couldn't resist the black friday pure turbo deal.

Car will be dropped off ASAP for PS2, inlets, DV+

What would I be looking at if I use JB4 with MHD?

I'm currently running FBO with MHD e30 map and I'm pushing 18-19 PSI. Would it go up any higher? Is it safe? I want to know more about the JB4 BEF with MHD

[TheXeve]

I have the same questions. I have a 2010 E90 N54 FBO with JB4. I run E60 with 93 Ocr. Is it better to flash the MHD E60 Map and run 4/4 on JB4 or flash the MHD E85 BEF adn 4/2 on the JB4?

Are both viable options or is the E60 (non BEF) map not suggested without pulling the JB4.

[Peen]

Mine's running well on MHD BEF. Targeting 22 PSI stock turbo, on map6

Going PS2 this week though.

Peen and thexeve, I didn't think you were supposed to run the MHD maps with the Jb4 and it sounds like both of you are. If running a JB4, I think you're supposed to use the BMS BEF correct?

Correct

[Peen]

This is the BEF, hence the thread name.
