Are you thinking you need a JB4 for some reason or something about flash only that you think won't work well?

There are tons of PS2s out there so I'm surprised you're having trouble searching for non-JB4 logs.

I am very surprised too. Cannot find a single one not running JB4.

Join the BMW N55 group on Facebook group, there are tons of MHD only PS2 PWG cars, both E9X and F series. I will have my PS2 and Helix on soon, just been too damn busy to find the wrench time.

Still in the process of tuning it. hybrid turbo comparable in size to ps2, spool performance HPFP and all supporting mods.

Hi

All my logs are public and all with PS2 so you just click away :) Current BETA-OTS is 0.34. I also have logs from custom map (work in progress) that is targeting 22psi (but capped at 85% WGDC) up top.

I have not been able to experience the my PWG PS2 yet (2013 535i xDrive). MHD Stage 2, Mon, JB4 BEF and JB4. I was hoping it would help on top of the MHD, be I wanted to go with JB4 and BMS WMI integrated for safety.

I have not been able to help my slow spool time and at this point wasted my money on the MHD stage 2 because I found out its not good for PS2's. I bought MHD for the flashing and then performance wasn't good with the JB4, so I tried to beef up the dme flash with stage 2. Long story short, I paid for MHD, Stage 2, and also Monitoring.

I ask MHD about my PS2 and they said they only have OTS for EWG, and that I can pay $600 for a custom tune. There are this I still want to change and upgrade, so it wouldn't be worth it.

Would the BETA for PWG N55 F10 be open still?

Here's mine..

Starting to look good, have a throttle closure towards the end there, but we're working on it. Car feel snappy!

Fabian gave me a file 0.34, and at first I had not yet added my AR downpipe, VRSF FMIC, and Larger custom TURBO intake (I now have MAF to 3" to 2.5" (2.25"ID) into the PS2.

I have the downpipe , FMIC, and turbo intake in and I did some runs this morning and sent them off to him. I still think now I have to lower my gap from .028" to .022".

Hey, would you mind recording cold start and hot start logs, i want to see the rail pressure in your car during these situations

Is this what you are looking for? I started the car cold and recorded it. If it is I will do a start hot.
