Settings look okay but your WGDC is really high for that boost level. Not sure what the issue is...maybe a boost leak? Low pressure and high pressure fuel looks fine.

Hey steve

Figured it out. Brand new sensor was faulty had fuel coming up through the pins of the connector. The next day after sitting i could smell the fuel. Thinking the sensor was loose i removed it and re installed it. Fuel started pooling in the pins itself. New sensor ordered. Will report back maybe 3rd time is the charm as for logs haha.

See the first post on the first page.

"4) Use the flash map that most appropriately matches the octane to be used. For pump gas no meth use PUMP, for pump gas with meth or light E85 or race gas mixtures use RACE, and for 40% E85 or more use E85 HYBRID map.

How do you save settings on each map individually? Do you set the JB4 via steering wheel controls into the map you want and then go to the settings in the app and they will correspond with the map that's currently selected?

Hey guys, I just noticed my Bit 6 (hybrid turbos installed) is set to off. I have MMP turbos. The car was dyno tuned and I have not touched the settings since then. Should bit 6 be on?

The answer is yes....bit 6 must be on/activated.... So that the Jb4 can recognise you running a backend flash.

But as The Beast has mentioned to you in annother thread, it depends on how your tuner has set up your tuning and what flash you running. The latest firmware 32/16 changes the Jb4 mapping when bit 6 is enabled. Why not post up a log to assist Terry or Steve to advise you on your current settings.

But doesn't jb4 recognize the BEF because menu 4 is set to 2?

Attached is a log from a quick gear 2 and 3 pull yesterday. Gear 2 is a bit wonky but 3 looks ok. I wasn't testing. I was just passing somebody...

Activating Bit 6 takes advantage of the latest firmware 32/16 and since you on very old firmware 32/9 i doubt it will benefit you.

Talk to your custom tuner but consider updating your firmware and to the hybrid settings.

You can read up on the changes in this thread page 24 post #581 where Terry introduces the latest changes.

Default Pure Stage 2 Rebuild Log Review - 08-17-2021, 09:27 AM

Been lurking for over 10 years but I've finally decided to rebuild the 09' 6MT 135i.

I'm running: JB4 G5 w/ BEF, Pure Stage 2 Hi-Flows, 3.5 TMAP, 2" Inlets, 2" Outlets, DeePees, Walbro 535 LPFP, Bosch OEM Plugs, Eldor Coils, BMS DCI, BMS OCC.

Please take a look at my last run (Map 1 w/ Page 1 Settings) and let me know if you are spotting anything. Comparing a jillion other logs makes me feel like it's ok but I'm iffy on the timing numbers and things like that still.

Also big shout-out to Terry. I upgraded to the G5 board finally but had an old harness. Had the Wastegate Activation fault that was driving me bonkers (even after changing the wiring) and he gave me a discount on a new harness. Now it's running strong. He didn't have to do that and did it anyway. He's a good one.

Nothing jumps out on log as problematic, run map2 next.

Interesting. I've compared a bunch of logs over the last year. Two observations when comparing the last two (with Bit 6 enabled) and all the previous ones (with Bit 6 disabled):

1. For all the previous ones (Bit 6 disabled) boost is on target except for an initial spike at spool, and WGDC very closely follows FF (which is good).

2. For the two new ones (with Bit 6 enabled), there is no initial spike but it is underboosting after 4,000 rpm, and WGDC is no longer following (is trending up compared to) FF.

3. Before enabling Bit 6, my FF/Wastegate adaptation was at 33, and since I enabled Bit 6 it has moved up to 50.

I read Terry's post on page 24 about v16 and how the targets have been bumped. Definitely interested so would like to try. But has the issue been resolved with respect to settings not being saved?

So I reset everything (Bit 6 disabled and reset FF / Wastegate adaptation to 33) and this is what I got on a 3rd gear pull a few minutes ago. No spike, and boost is back on target. FF / Wastegate adaptation did however adjustitself to 45. And WGDC and FF are not perfectly aligned although now back to trending in the same direction, so overall better than with Bit 6 enabled. Undoubtedly can do better with Bit 6 enabled and some DB tweaking, but will wait till next week when the weather is a bit cooler and less humid, and may even try v16...

Does this mean that with certain DB settings it may be better to disable Bit 6?

Should also mention this was a Map 5 run, on Canadian 94 pump gas (which is basically 91 with an e10 mixture), at about 30 degrees Celsius (86f), with IAT at about 36 (97f) and very humid, at an altitude of about 1,100 ft above sea level.

On hybrids , you do want to disable rpm ff gain, raise ff manually or let it adapt.
Once it adapts, boost will be more on target, after that, you can tweak db as needed.
Let it adapt. Do not go changing a bunch of stuff at once.
