Here's the results results of my custom e30 tune flashed via MHD
Mods:
DP
VRSF 7.5" FMIC
DIY intake
XHP stage 3
Stock fuel system
All runs were done in 4th gear.
Red run is the MHD stage 0 flash with e30 in the tank.

+97 whp and +160 tq over stock

Do you have any comparison to stage 2+ E20 ots?

Red is ots e20. Blue was one of my early revisions, was down on power up top because it was a little on the rich side.

This is a PWG, not an EWG.

Nice increase from ots👏🏻

So what is with the wonky power curve?

Aren't the M2 Turbo'folds different from the non M models?

I think an inlet would help me get a little more flow up top, my turbo is tapped out up there.

Yeah it does look weird. Torque absolutely plummets in the upper RPM.

Datalogs from the runs?

Looks like it makes barely more power than OTS map also

WOT808 · 10-04-2021, 01:50 PM

Here's shots of the logs.
The OTS maps were surprisingly aggressive but there's gains.

Can you send me the datazap links please? Yeah there are gains vs MHD OTS since its slightly conservative to avoid HPFP crash. The dyno chart makes sense with ~2psi increase. I'd like to look at the rest of the log though, especially the final iteration vs OTS map.

Also did you measure ethanol content? I'd be surprised if you didnt have HPFP dips/crashes with E30 at that boost level.

Allegedly. I can show some for f22/f30s. It just seems of to tap out so quickly before 6000RPM.

That would be great. I have an F15 X5.

Huge deviation in requested boost and actual, as well as load control. This is thejeremyman9 Domain though, so I'll wait for his thoughts.

None of those graphs have rpm on the x axis. The EWG graph doesn't make as much tq as I did so the tq drop in that graph isn't as drastic as mine.

I don't like boost/load actual to ride target.

Yeah, a couple of things. First, HPFP is crashing from 3500-6000 rpm, which is exactly why MHD OTS map doesnt run more boost. They dont push hardware past its limits lol.

The map basically looks like they just added +4 psi boost target to the MHD OTS map. Generally follows the same curve including the taper after 6500 for a "soft limiter". Maybe added 0.5-1 degree of timing target as well. WGDC is in the upper 90s so turbo is basically maxed as well (especially at 5200 rpm, its literally maxed).

The boost drop off up top seems a bit more than you would expect. IIRC, BM3 stage 2+ logs show people holding nearly 20psi more consistently throughout the pull, not falling 5-6 psi below target in the upper RPM. For example in my log i just took yesterday i have basically the same or slightly higher actual boost in the upper RPM despite this target being higher.

https://datazap.me/u/thejeremyman9/3...=0&data=4-5-17

It is what it is i guess. I wouldn't run the tune, its way too aggressive for stock turbo and HPFP IMO.

Peak power right around 5.5k so a little higher rpm than mine.
The custom tune power curve follows the OTS power curve on that graph.

X5 has a different inlet designed than the f2/3x. That could be why it peaks a little lower in the rpm range than the f2/3x turbos. I haven't seen a stock turbo pwg car hit 17 psi on a single gear pull and I've tuned a few of them.

Also, the dyno rpm scaling could be a smudge off. The dyno log revs out to 6.7k before shut down.

WOT808 · 11-17-2021, 09:31 AM

Upgraded to an FX180 hpfp and run pump e85 now.
Haven't been back on the dyno but have been making some progress with my 0-60 and 1/8th mile times.

Not bad for ~5k lbs with me in it.
