I had done 2 logs today, and they show exactly what I fell in the car: Shure it's Much better than stock, V8 has an incredible driveability, but it's missing a little power.
Here are the logs, reaching 15,5 psi, witch is less than I think it should reach, but it's what the DME it's targeting.
My question: what's better: run stage 2+ and keep an eye on the IAT or buy the E30 package, and run stg 2 with E30 (and put a little more E on the tank to reach the E30)?

What are the differences between those 2 ?

Thanks

The 2 logs are in the link below:

You really need a better FMIC before stepping it up, you've gone from 82 to 133 F in a 1,5 gear pull, that's a lot...

IF you have E25 available you should use that.

Anyone know what the .enc file is? Its a locked file in the Debugging folder under mhd flasher n54.
I currently have 1360 .enc files (1.06 GB!) and wonder if I can delete them.

29dc cylinder injection cutout

Hey guys

Just recently went fbo with mhd stage 2+ on my 08 335i, but ive been having some problems with some of the WOT pullls ive done, Been getiing the 29dc cylinder injection cutout code a few times. Anything other than WOT no problems.. No codes when cruising or rough idle.
Changed to brand new ngks gapped at .022 and brand new coils after fbo install.

Ive read alot about the potetial causes for this code on varies forums but i cant seem to find a smoking gun, reed that it could be a few different things causing the issue.. Carbon build up etc

Did a couple of pulls today, on the first one i did a 2.gear pull and caugt the little bastard throwing the code while i was logging.
Deleted the code and went out and did two more pulls from about 2500rpm in 3.gear - and a couple of seconds into 4.gear - No codes this time..

But studying the datas after i can tell that something is going on with the lpfp psi. It dips well into the 40s and the hpfp psi then obviesly follows down low. The lpfp psi also seems to be quite high sometimes when not in WOT.
There is a few other parameters in the logs that also look a bit shady

Im leaning strongly towards a faulty lpfp, but i`ve ordered a low pressure sensor just to rule that out before buying a new lpfp.

Do you guys have any other suggestions to what the problem could be?

Hope some of you with a bit more experience than me could look at these logs..
Did a rookie and missed 4th in the second log..

The three logs im referring to:

https://datazap.me/u/hoff/log-153995...og=0&data=3-20

https://datazap.me/u/hoff/log-153995...og=1&data=3-20

https://datazap.me/u/hoff/log-153995...og=2&data=3-20

I would really appreciate some help/ guideance

Thanks!
