Too much corrections.

Attached there are 2 short pulls. One in 4th gear and the other going uphill under WOT (on this one there are some corrections, wonder why). Lmk what you think. Both pulls are 10 min apart.

Wow that's a fast tune. Surprised railpressure holding up really well on tu hpfp. That wgdc tho, your turbo startin to sweat lol.

[IMS-340C]

Yup, stock turbo pretty much maxed out and yeah the TU HPFP is a champ.

In this log I managed to reduce WGDC a little with even more boost:

Hey guys,

Recently my 340xi has been acting weird on both E30 and 93 BM3 Stage 2 tunes. Poor throttle response, and I actually got a drivetrain error and had to limp home after a car show. I pulled codes thru BM3 and am constantly pulling “100001
Throttle valve, function: sticks briefly” and “100501
Throttle valve 2, function: stiff, too slow”

I did 2 quick pulls in sport and the logs are below.

Please let me know. If my motor is bound to blow I want to stop driving this POS lol

Hey guys. Currently on a custom flex fuel tune from CD919. The car performs well in normal cruising and semi-WOT (50%ish throttle angle), but WOT has issues as of recently. When shifting gears at WOT the car will pull timing, and sometimes set off the Knock Detection. Can anyone help me out?

Car is currently on E50 (X85 Mixed with 100 Octane to get an E50 mix) pushing 500hp and 500 lb/ft of Torque on the stock turbo. Pure 800 turbo is coming in a week.

Mods:
VRSF Downpipe
BM3 Flex Fuel Kit
MST Cold Air Intake
MAD Axle-Back Exhaust

Log #1 w/ Knock: https://www.bootmod3.net/log?id=67db...02fb3bd428b927

Log #2 without Knock: https://www.bootmod3.net/log?id=67db...e26a0c627c36e3


EDIT:
Figured out my turbo seals are going bad. Oil pressure dips as soon as boost is built and then overshoots once I let off. Car is also burning a quart of oil 2 weeks after changing my oil.

Hey guys, I have just flashed MHD state 1 95ron, how do my logs look?

Worth trying the 98ron map?

Looks very good, yeah you can give 98 a try.

Great thanks.

I shall get a log on the 98ron map and report back.

Timing corrections look good but fuel pressure dropping and ignition timing crashing.

Unplugged the JB4 w BEF and flashed stage 1 93 MHD. Felt stronger. 93 shell and couple gallons of e85 — prob e20 or less. Can I just add more e85 to get rid of the corrections shown? These runs are 10 min after the flash — maybe it just has to adapt

I was low to mid 14 AFR w JB4 throughout. This is better but still high?

possible hpfp crash? moved to california and i needed to add e85, so i added 2 gallons. It looks fine in after the initial throttle stab though so idk.

Stage 2 91

[IMS-340C]

Yeah HPFP struggling, but at least timing corrections looking good.

[Bondy]

Yeah I measured the e85 to be right at 85% so I should’ve been careful, oops

do you think if i try the e30 tune and get my mix right it would be alright? or i'd run into timing issues then because of the bad gas...

[IMS-340C]

If you reduce Ethanol you will get timing corrections and you will need to run Stage 1.

Not the stage 1 e30 right? Just 91? But do you think a TU pump would solve it?

Edit*. Shouldn’t the e30 maps have less boost at lower rpm to keep the fuel pump ok?

[IMS-340C]

Yes TU can handle it easily, it can push E42 at 22 psi or E50 at 18-20 psi.
