If you take his log I listed E20 map and he's running E30 and calculate hp at 5800 which is about max Hp @ 590nms = 480Hp... so comparing to actual slip time I listed above of 487Hp running BM3 E30 pretty much matches up... this is only running with XHP... I don't get the same results without XHP...

P.s. ... this is crank...

There’s not an XHP tune for the M2 DCT. Some say they have something coming, but they just released it for M3/M4 DCT, which is different than the M2 DCT, so I’m not optimistic.

Well you still can use the MHD tune/logging and figure out if any of the add-ons are adding power or not with out the XHP tune... just won't correlate with actual Hp... That's what I'm doing now... I want to compare one more log when my IAT's are the same as they were last november (55f ambient) to see how much more Hp the Fabspeed Dp added that I just installed... then I'm gonna flash it XHP and log it and then run the E20 map... I'm running 95map now ... boostane/93gas...

Looks like BM3 has “Clutch motor torque value“ as a channel.

At first i thought maybe, but im not convinced because i just took a quick look back through logs and things don't make sense. For example in the logs in the VD thread there are higher torque nm values on the IC+CP stage 1 and IC+CP+DP stage 1 logs than the IC+CP+DP stage 2+ logs when the stage 2+ tune was obviously making more power...

Also i looked at more recent logs, and all the sudden it went up from high 400s to low 600s on logs taken about a month apart and there was zero change (hardware nor tune) between those two logs. The only change was a change in MHD app version (not tune version, app version), so they must have recalibrated something or change the PID for that data channel.

Compare these two:

https://datazap.me/u/thejeremyman9/4...0&data=4-25-37

https://datazap.me/u/thejeremyman9/4...0&data=4-21-32

So I dunno...

Honestly, VD is a much better tool for this purpose (delta between tunes/hardware changes). Or, use acceleration times as a proxy, which is more or less what VD does in the backend.

I notice from mine to yours is when you and everyone else flashed XHP... before that they were in the same ball park except the E20 was at the higher end in Hp ... so what is Virtual Dyno saying about your HP on your log I listed... at the crank?

Also want to point out that guy had coil overs which I bet contributed to .2-.3 shaved off a stock suspension car due to time for weight transfer and wasted torque etc...

XHP does not explain the differences between my logs though. I installed XHP 4/26/2020.

This is before: https://datazap.me/u/thejeremyman9/4...0&data=4-25-37

This is after: https://datazap.me/u/thejeremyman9/4...0&data=4-25-37

The frist log is 91 map, the second log is E20. To your point the E20 does show slightly higher torque nm. However, I also installed XHP between these two logs, and they are both reading in the high 400s. So the XHP install does not explain the sudden change in torque readings to the low 600s with the same hardware.

I went back through my logs chronologically and the only thing that explains the sudden change is the update in MHD app version from 1.48 to 2.11. The next set of logs i have after the two above was about a month after the latter log, and it has the sudden increase but no change in hardware or software.

https://datazap.me/u/thejeremyman9/4...g=0&data=21-32

Not sure which log you listed but after i recalibrated by VD inputs my stage 2+ E20 logs show high 300s whp and wtq, which is on par for exactly what i think it should be making... lines up with the ballpark figures for MHD stage 2+ 95 maps, and the E20 should make slightly more power. I would re-emphasize however that i dont use VD to try and figure out how much HP im making (irrelevant) but only as a tool to see the delta.

that's weird... I'm in the high 400's and I just reflashed my car just a month a go... I reset my phone and had to even re down load the app so I hope I have the latest version... says V1.08 on Datazap I have... how do I update?

Again im talking about app version not tune version. v1.08 is the tune version. 2.11 is the app version it seems. Both are listed on datazap logs. Take a look at the last one i posted.

I just check for updates through play store; dont do anything else fancy. I think the major update was when they revised the gauges and whatnot. Perhaps around the time they changed the purchased structure as well.

This guy has V1.54... I figure it's PWG?

Here is my screen shots...



So if everything is upto date then I don't know why our Torque Nms don't match... I figure XHP but from what you say I don't know now...

Not sure; maybe we can start a new thread or you can PM me. I think we derailed this thread a little. Sorry OP, hope this was helpful at least marginally lol.

Every thread has someone raving about MHD it seems.

One advantage is it's load based... thejeremyman9 can tell you all the advantages being load based over in the MHD thread... lol...

Actually, its the opposite generally. BM3 users typically advocate heavily for BM3 whenever a new person asks what tune to run, while MHD users are relatively silent. In any case, we weren't raving about MHD here at all or touting it as a superior tune, we just derailed your thread a bit in the discussion for torque nm in the logs, so apologies for that.

[FastF30]

So getting back on topic... is it worth upgrading the fuel pump... IMO ... if you have the cash... most definitely... this guy is running MHD and upgraded fuel pump and he walked.. no... ran away from the other guy ... N55 has a lot more power than people think...

Now granted the other guy was just stage1/manual but the way the 335i pulled it will stay with the guy even if he had stage 2 pump gas... maybe a little more... I'm impressed...

Damn that thing moves out on a stock turbo

Just watched this video. I assume he has a stage 2 HPFP for full E85, but surprising it seems to work since the other member on here said he couldnt get above around E70 without LPFP issues. Also not clear what custom tune he is running. Too bad these people never provide details or logs...

According to the recent kies video the F80 M3 made 460whp/531wtq with just the stage 1 tune...(although hub dyno) I dont see any way the F30 is making that on stock turbo even with full E85 and custom tune. He doesnt even have an inlet or anything besides CP+DP+ 5'' IC.

Just seems strange. I think the manual and the extra M3 weight are the major reasons it won.

in a quarter mile a manual is .2 slower than an auto... for every 100lb's add .1 ... .1 = a car length... so giving the passenger weighed 200 lbs = .2 ... add the stage 1 which is probably 35+/- horsepower and 10hp = .1 in the quarter it's basically like racing a stock M4 DCT .... which it still majorly walked on... still very impressive... gonna try to contact him on instagram even though I vowed never to use it but this is an exception... lol...

I watched the video again and he said he's running a "Spool" & Full E85.... like I said before I'll try contacting him thru instagram... just gotta create an account now... lol...

I got that part. But no further info on tuner (it just says "MHD" but there's no way its a OTS map), stage of HPFP (although almost certainly stage 2), etc. Interested to see what you find.

Here is his response on instagram...

"Thank you. I am using full E85. My tuner is pureboost.de he is based in Germany and his turnaround time is usually 1 day. He is also the most affordable. Also don’t upgrade your LPFP until u upgrade your turbo."


So there you go.... looks like I'm going Spool.....

"I went Spoolfx150 it’s enough for full E85 and max out the turbo"

Bet you any money that was the trick and LPFP still working... shoots out 1.34cc .... Dorche stage 2 shoots out 1.465cc.... Dorch stage 1 = 1.221 Supra pump 1.1.... Spool must be in the sweet spot for everything to work...
