i havent tuned for e85 since i have AIC2 and it uses tuner pro for port injection. Different software from AIC1.

we tuned on e40 last yr and made 530hp but that was with a massive fuel leak unknown only putting out 36psi of pressure. Also didnt have PI at the time so we were limited.

Are those crank #s or whp? And you have xDrive correct?

Those crank numbers are reassuring $howtime456 so we're on track.

Some interesting news today from David.

He emailed me this:

"I'm trying to get my hands on a definition file with a table I need to adjust your tune. I'm hitting a limiter on the DME side forcing down the load ceiling."

This is exciting if he can find it. This is the issue Alex had brought up to me in regards to missing tables. Sooo... if D Shoup can add some more tables to account for a higher load actual, then we're in for some fun and 500rwhp might be in range. That's gonna be like 725-50 torque nm.

Hopefully we'll know soon.

Finger crossed and hope so, otherwise I think our cars might need JB4 with BEF to run higher boost. $howtime might not be having same issue because he probably got a newer DME as he is on 640i platform.

Just a thought.

Running more boost with a jb4 or BEF will be defeated by the torque limiters thus limiting your load tables. Stick with a custom tune.

These tables exist on the F30 N55. Maybe he can get em from a M2 N55 variant.

What to say that our dme's software will even recognize these tables?

Then we may never cross the 500whp with high e85 blends. Maybe the best that can happen is 450whp with more boost. Or we talk to $howtime456 guy on how to get to 500rwhp on race gas.

The good news is I've clipped the 400rwhp mark on D Shoups tune. He's gonna fix the PSI drop at 5600rpm. My car is much faster now not spooky fast, but competitively faster. 3rd is very strong and 4-5 on the freeway is gone city.

facts. One would need XHP stg3 to remove those torque limiters.

i actually thought you guys had the missing tables already. I know Kevin had to add a couple of fuel tables in with XDi. Made a switch to Spool and even more tables had to be implemented.

good luck. My tuner wont even send me a e85 map now unless the car is on the dyno. He likes to see how the car is running first before any adjustments have to be made. Also i have a weird fuel setup. I run -8 fuel line from the fuel hat all the way up to the HPFP. More volume of flow. Ill DM you the race gas to get.

He did add the fuel tables, but there is a limit issue in DME for load which is separate then the fuel tables issue.

"With the BEF we scale torque HIGHER than actual, have since we released it, to ensure the trans line pressure is maxing out. If you want to scale torque back to actual you'd need to lower the torque-eff divisor factor in the BEF and monitor the calculated torque JB4 output parameter in logs. Those expecting new trans software to improve holding capacity, IMHO, are going to be disappointed. But if it can change the shift points and stuff that will be well worth it.". -Terry

^ and xHP tune, I dont think we would run into the issues that are now with dme load, which we're facing by directly tuning it on the car with flash (let JB4 handle the boost).

$howtime you probably have different dme then us old F10s so that is why you didn't hit into same issue that we did.

Good info... I'm curious to see if David can figure it out.

[Bmwdoubles_]

He just sent me a new rev with the new tables. We're testing it out. Stay tuned. ziekxq I'm sure he'll be adding it to yours too.

Wether he does or doesn't I can tell you it's one of the best tunes I've had in my F10. Could be due to my recent hardware upgrades too but he's got N55's tune dialed in.

Lol my n55 on 93 oct feels like a beast but I was having some over boost issues during gear changes and then ran into same issue that you were facing.

Sounds good, I am waiting for my update.

[BimmerHausPerformance]

Doubles, can you post a video of some pulls so we can check it out? Give us a taste of the world you are living in! Streets are empty man... now is the time! And if you are in CA how in the world are you passing smog?

I have spool...pretty sure spool fx150 is 50% more flow than stock, xdi-35 is 35% more, so you should be good with xdi-60. There's just something unique about spool's tuning, Wedge had to iterate some to get it right, and it's not available through MHD yet although xdi and dorsch are.


(Been lurking on this thread, since I'll hit up David eventually )

I had already bought the FTP inlet and probably still would have just to be safe - you've probably read about all the wgdc/etc issues with stock inlet that I have - but interesting to see his opinion...

AZMcRacer had huge restriction with stock inlet and wasn't able to push more psi high in the rpm until he switched to custom inlet. I have his inlet as well and per David Shoup the inlet is high quality and really good. I am hitting 18 psi and never go above 65-70 wgdc.

[Bmwdoubles_]

I sprung a leak with AZ's inlet. I replaced the seals on it but it's still allowing for unmetered air. In all fairness I hade bend the mounting portion that holds the inlet to the engine (not the bolt to the turbo). This could be causing the inlet to unseat itself.

I discovered it when I tried to perform a leak test and the system wouldn't pressurize and a huge air leaking sound as soon as added compressed air. This would account for my recent wgdc random 100% spikes and slow full boost under 3k.

Switching back to stock inlet for now.
