F10 M5 MHD Stage 2 E30 Misfire HPFP?

[AgentE]

Hello everyone. After our endless MHD correspondence, I wanted to consult you here. I used 91,93 and 95 oct maps. I bought ECA for the E30 map. I set the mix to be E30. I got a misfire warning on my first try. I shared the situation with MHD and they still asked me to log even though I got misfire. As a result, there is a possibility of damage to the engine while doing this. When I spoke to the custom tuner, he said that the HPFP of the F10 is insufficient. Anyone using the E30 without upgrading their HPFP? Do you think the problem is insufficient HPFP?

I’m running Mhd state 1 e30 and the car runs perfect and pulls extremely hard. You can try stage 1 and see how it goes. Both stage 1 and stage 2 e30 target 22psi. I think the big difference is torque down low. The codes you getting are similar to when my lpfp was crashing on my e92 under high boost.

How do you guys like MHD overall? Been debating on getting it as well

Hello.
All problems solved!
For some ridiculous reason... I wanted to let you know, maybe it can happen to others. But it happened to someone on the F10m5 forum.
I bought the original spark plug and ignition coil 500 km ago and had them fitted to my vehicle in order for my modification to run better. Later, I started to experience misfire in the vehicle at around 4000 rpm in 3rd and 4th gears. When I ran into this problem, I had them removed to replace the old ones. The parts were identical down to their numbers. Then I read a post on the forum. Regarding ignition coils which are Slovak is causing this. I went back to my old igniton coils. And now the E30 OTS is running smoothly. And super fast. Thank you for everything.

This is why forums are awesome! Good investigation work and glad it was an easy fix.

Primary reason I buy my parts from BMW dealerships and then have my local shop do the work.

I bought my coils from FCP and they are delphi coils. Metal body. Are these any good? or should I return them for bosch ones? They were sold as OEM..

Although I do not have a clear knowledge about this subject, I heard that the metal body ones are original

MHD Stage E30 map with E30 blend

Hi everyone. I experimented many times on the MHD Stage E30 map. Many times the car stalled at the top rpm of 4th - 5th - 6th gear and gave a drive drive error. When I checked the error codes, I always saw the same error code. I got error 11A002 "High Pressure fuel, plausibility Pressure too low". Taking into account the upgrade suggestions of the users in the forum, I bought the F90 M5's Hpfp and installed it in my vehicle. My car is currently running out of breath on the E30 map.

So even f90 hpfp didnt help with e30?

No, It supported the E30. Then I upgraded to E50. It supported E50 too. No problem.

[blazarov]

Is the f90 hpfp install hard and labor intensive? Is it plug&play? Ive seen references for adaptors but not sure if they are needed. I guess you need a tune after the f90 hpfp? I currently run BM3 st2 OTS and see there is a setting for aftermarket hpfp but Spool only.

It's not a difficult connection. They just soldered a socket on the end. Just plug and play. No adjustments were made.

I use MHD. In my country there is no fuel option called E85 mix at the fuel station. There is only 95 ron (91 oct) fuel here. We mix it with 100% Ethanol compound that we buy from outside and create the ratio ourselves. For this I have an ethanol content analyzer in my car so I can see directly on the gauge that it is E50.
