Added T9 bringing back trans temp and consolidated the firmware descriptions, I had some of them listed under the wrong firmware version.

G5_ISO_32_12

1) Adjusted boost safety system so that boost safety for map4 (stock boost profile) change over is 3psi over map target OR 1psi before sensor runs out of range. Whichever is lower. The user adjustment boost safety setting is now used only for in dash boost gauge calibration. Boost safety won't trigger unless boost is at least 15psi.
2) Fixed another bug in the 2STEP logic. Seemed to be working much better on our development car. Let me know!
3) Changes to try to fix bug with some logging channels like IAT or oil temp dropping out.
4) Added back map8 for valet/no boost mode. Note if NOT equipped with a BEF you may get a "boost below target" false alarm fault code when running map8.
T9) Put back trans temperature logging

Wont this cause people running E85 BEF on Map 7 that targets 19.5 PSI to be thrown to map 4 who are running factory map sensors?

Maybe. Better than them running off the edge of the TMAP sensor, though. Upgrading to a 3.5bar is very easy.

Hi!
I just bought used jb4 and updated new firmware and now the car works poorly. The old firmware was 27/13/2. When I was updating fw, I didn't know that this update wouldn't work in my jb4

. Is that 27/13/2 firmware for jb4 G4 or jb4 G5?
Can someone send me the old firmware or can I restore the update or is there some another solution? I hope I could get jb4 work again or otherwise it was totally useless to buy that. Too bad I didn't know that it could be so old jb4 when I bought it that the new firmwares dont't work on it.

Now Im confused. I took this photo of My jb4 and this looks like g5-Iso? Am I right?

//2 is G5.

pepper135i · 07-21-2018, 11:36 PM

terry I’m bit confused .. is there a map 8 like before? Or is the new “map 8” the valet/transport mode 4-7?

Terry, as far as IAT and oil dropping out, I have a log that lost cyl 6 logging completely. Also have logs where HPFP drops from 14 to 7 then back to 14. Could this be a bug ? Lpfp stays steady as well as AFR so it doesnt seem like its a hardware issue. Also replaced my hpfp to latest version and still logs the same. Does it random also. Cant reproduce on demand.

Terry @ BMS · 07-22-2018, 03:53 PM

I'd have to see the log myself but no not likely to be a bug especially on fuel pressure which is an analog input.

I have a throttle issue.

With stock flash (OEM PPK N54) the throttle is pretty sensitive. Boost is applied really early. I have the DME on IJE0S and am equipped with a DCT (no INA0S flash)

My JB4is on the latest firmware.

Playing with Menu 11 seemed to change the responsivness. I later found out that menu 10 and 12 were not in default settings (values not noted) and i put them to your recommendation.

DEFAULT SETTINGS:
Menu 10: 3000RPM
Menu 11: 1000RPM
Menu 12: 2800RPM

But now changing Menu 11 isn´t changing anything. 0 or 5000 is the same?!

10% mechanical throttle seems to give me 50% boost. This is horrible on the track.
So i unplugged the white connector and flashed mhd stage 1+ with linear throttle. No change.
Back to Stock and again Stage 1+ with linear or without.

Nothing seems to be helping.

Any ideas why my throttle pedal is stuck in weird mode? I don´t know what to do anymore.

2 step is so much better thanks terry. Mine would bounce around the set rpm for a sec then go crazy much better now but I dont get flames anymore though which is probably a good thing anyway

Ripley · 07-28-2018, 08:20 AM

I hope this may help, I did a menu 6/8 gauges sweep test with my M3 cluster metric version. It stops at 180 km/h when is set to menu 5/8. It works fine if set to menu 5/7

Check out the new anti-lag 2STEP integration if you really want to make some noise and break parts.

I had some questions about the jb4 id like to talk about though dm if possible thank you

Put my support request in the wrong forum by mistake. It's been moved from here and relocated to the correct forum.

PrzeChuj · 08-02-2018, 03:28 PM

Uploaded firmware to T9 to test out. Logs come out blocky or just straight lines with 90 degree angle really funky looking. Also target boost hoost has dropped 2 psi. I was running T2 previously and would hit 18+psi all day every day. T9 barely gets me to 16psi hovers around 15.1 on a few logs I pulled . Something chamved forthe worst. I'm gonna test T6 n the lorning to see if its better but I'm not feeling the T9

Terry @ BMS · 08-02-2018, 04:22 PM

Support requests go in the support forum, and for any tuning issue a JB4 log is required for us to help you.

Terry @ BMS · 08-03-2018, 10:05 AM

Anyone tried map8 on the latest firmware? It's a zero boost valet map. Want to verify its working properly.

cebrailbakan · 08-03-2018, 10:14 AM

I tried for a while Terry , the car is literally 100whp , lol. No codes popped up yet , thanks this great future and please do not take it back , I want valets be shocked when they kicked the gas pedal all the way down !
