Not just leaner AFR targets, but a lot more ignition advance. So you should be making more power with the new E85_IGN boost for boost. On E70 (rather than straight E85) map5 at 24psi peak may be a better option but we'll just have to see the data to know for sure.

Added TEST11 firmware to S55 JB4 thread with revised target blending. Was much better in my testing on Sport+. Load and let me know what you think!

Will get this uploaded in the next few minutes and have some feedback later today. Road around a good bit today with the TEST10 and v13 RACE BEF, driving in a little bit in Comfort, Sport, Sport+, as well as running straight 93 pump gas and E35 mix, in various degrees of traffic and open highway runs.

I will say that Sport+ is a crap shoot right now.
Sometimes the takeoff is smooth from a stand still, other times is jumpy like the car used to be before the GTS DCT flash.
Same goes with flooring it from a gentle rolling start.

Terry,

I noticed after Ive uploaded test 11 firmware, the jb4 still labels as 1.8.4//5? Should it be 1.8.4//11?

No, //5 is the board type. TEST versions aren't labeled internally in the firmware.

Hi Terry. Yup no doubt about it v13 ign on even E70 Map 6 25psi is quicker than v11d 😀. And so smooth too.

Timing is also more consistent. Before one or two cylinders would be slower to keep up with timing. Im still using oem plugs but will soon swap them for the 97506 NGK ones.

Didnt have the road to fully log but did one squirt in 4th. Seems ok?

Ran a few more logs under various driving conditions (highway vs city; mid vs high gear; WOT vs partial throttle), as well as with different mixes of E85.
Will make individual posts for each log grouping.

All logs captured with the same vehicle configuration (Map 5, Sport+, S3 DCT settings) and JB4/BEF versions (1_8_4_TEST11; S55 RACE v13).

Attached logs are running E40.

Try the regular E85 BEF as ign isn't going as high as it we have it mapped, at least based on those two short pulls.

Timing should be around 12 deg up top? You think there is some knock?

I noticed my ff is climbing too after the two pulls. Ive left the duty bias unlocked as well.

Ill do a few more pulls.

Looks very good, I don't see any knock. FF is learning up because you're a few psi under target. You can raise FF to 55 and get another log, that should help you hit target boost.

Oh ok tx Payam.. also boost taper after 6000rpm is quite normal on stock turbos?

Whats the deal with the FF auto-learning? Is that a basic feature, or is it activated in user settings or with certain maps?

Also, seems the duty bias auto-learning is no longer a feature with the latest firmware, correct?

Just want to make sure I have everything set properly to let the JB4 algorithm reach its optimal state and maintain safety parameters.

FF auto learning is on by default, do not disable it. Duty bias learning was hit and miss, do not enable it for now.
