Well... with the same tank of E30 and nothing else. I am now having more timing corrections along with timing delta for knock adaptations. I am not sure what is constantly changing with this car that makes every data log completely different than the last.

Shoupe told me my AFR is a bit higher than target (13.5 instead of mid to high 12's). Said could also write me a custom tune with more safety involved but... I am just so curious as to why I am having so much timing corrections compared to others with the same MHD stage 1 tune and mods.

Switched to the E30 stage 1 map to see how it reacts. Minimal to no timing corrections and no knock adaptations. However my AFR went even higher to 14.5. I'm wondering if I run 10 more logs at this map if the car will be wildly different log to log like it does for the 91 map...

Seems to be clean besides the high lambda/afr

Would resetting my cars driving adaptations be advised at all?

Good evening everyone,

I was facing an issue with my boost, the boost was going over the target by 4-6 PSI

I had to tune my car back to stock file after changing some parts, I did a log with my stock file after returning the transmission to the Oew calibration, I need someone who’s familiar with logs to check it up and tell me if there’s any issue or not

Thanks

Here you go

Note, I still have the charge pipe on, the air intake and the down pipe

Looks like a wastegate problem.

Hello! So I just got round to doing a log but I'm not sure what to do to make the correct info avail. I have just mapped stg 2, I have an AA downpipe and a MPPSK. These charts on datazap seem a bit complicated. What's the advantage of them rather than say uploading a screen shot from MHD where everything looks much simpler. Sorry this is my first time using the log. I'm using V-power and using the 91/95 map. I will probs up the fuel map and do another run as I can see i have no timing probs or knock as far as I can tell.

Yeah timing corrections (knock) look great, but boost is very low high RPM usually this map produce 15-16 psi through the entire RPM range.

Thank you for taking a look. Do you know why this would be? I forgot to mention i am also on XHP stage 3. To be honest I'm a bit disappointed with MHD. My plan was to do the TU pump next then I find out they don't recommend a stage 2+ tune with a catted down pipe with more than 200 cel. I am waiting for a technical explanation on this. If it just means I won't reach the max HP then fine, strange though as the AA pipe is good for way more than a ots map can produce.

[IMS-340C]

My only explanation if you were on very low fuel, it triggers safe mode and reduce boost.

You could be a genius! Crazy if that's a thing but I think I may have been on reserve or very close to it. I guess it depends on the level it decides to trigger safe mode. I filled up on the way home. I will see if I can do another run tomorrow, thanks again for helping out peeps like me!

I went up 1 level on the fuel map, 98 RON, first pull didnt produce any timing corrections but by pull 5 I was getting -1.5 on 1 and -1.6 on 6. seems to be pushing more total boost but I dont know how to read the boost vs RPM. This link should contain 3 pulls, 1,7,8. I did a few.

https://datazap.me/u/aball/1722025?log=0&data=5-19

[IMS-340C]

Yeah looks great now and there no relation between boost and RPM so there's nothing to read

Woohoo! thanks, youve put my mind at rest, I will probably do a few pulls every time i fill the tank to keep an eye on it.

Regards the boost I was refering to this part of your post.
"usually this map produce 15-16 psi through the entire RPM range." I saw it was hitting 15 so i presumed there was some evidence of loss at lower or higher.

Very happy now, just got to decide if its worth getting a 200 cel cat and selling the 400 AA.

Hey guys. Buddy’s car is correcting a shit tonne of timing. I haven’t read logs for a while. Could someone spread some light on this log and make sure all is ok!

https://datazap.me/u/bmwaddictt/f23-...og=0&data=5-25

Car is on MHD Stage 2 91oct map. Just your usual bolt ons:

- Catless dp
- Catback
- MST intake
- Inlet pipe
- xHP Stage 2 + Ignition Cut

Thanks!

[IMS-340C]

It's not that bad but better tune it down a little.

Tell your friend to try the following: Flash MHD MAP > MHD+ Multi Map then run Map 2.

How does this look?

I'm running MHD stage 2+ and needed right at an E25 mix to clean up all the corrections. Not sure how BM3 and MHD say it's a 93 tune, I haven't seen any logs that didn't need E to clean up.

[IMS-340C]

I agree, it's because they wanted to take advantage of the TU HPFP in the midrange as this is where the stock HPFP struggled the most, but they forgot about timing corrections.

I was thinking this would be my next upgrade. Do we get lots of corrections on our cars with this map requiring ethanol? MHD.

[IMS-340C]

Yes if you're buying the TU pump just for 93/95 fuel without Ethanol it's definitely not worth it.

Thanks thats very helpfull, I will not be going down the Ethanol route so you have saved me a few hundred quid. Things might change though, I just watched Osprey do the OP500 kit, 520hp on pump gas, one to think about.

[Speeddemon96]

Does anyone know if the Active autowerks dp has enough flow for stage 2 tune?

I have tried ANC91, 91 and added 1.5gal of e85 to my full tank of 93 and still get timing pull, but on stage 1 it runs with barely any timing correction only on one cyl and less than 3°.

Dear B58 fellows,

My turn to share a log, hoping for some advices.

My car suffers from Valtronic issues (range faulty, impossible to reset), and this materialise with the throttle keeping open for a 1/4 of a sec. when I lift the accelerator pedal, or when the engine start. Car runs fine though, no limp mode or so.

The valvetronic engine was changed, the reset procedure (with the pedal trick) done with no success, and the mechanic can't do it either with ISTA software. Next step will be removing the valve cover to check for the excentric shaft.

Anyway, I did a log today, and I saw that the rail pressure actual PSI is much higher than the rail pressure target, at least at the beginning of the pull.

Is it normal and if not, is it a separate issue, or related to the valvetronic problem ? (and why would it be related ?)

Many thanks to the community for you help!

Here is another pull from today, in 3rd gear:

https://logs.mgflasher.com/log/40b43...19&wide=1&vt=0


Strangely, there is 0 timing corrections on both logs, which is great, but is it even possible ?
