Did he send you adjustments or change the map? I just looked at the zip file and the E85 map was last modified 2/2/2018 7:47PM.

Because of ISO mod.

Have to agree with @Cloud. Customer service is definitely not an area where Terry/BMS are lacking. I've emailed logs/questions and made forum posts at all hours of the day/night. Replies are almost always back less than 24hrs and typically within just a few minutes to an hour.

If they aren't getting back to you almost immediately, there's likely a good reason for it. I'm sure the guys have stuff going on in life outside of the forum.

The problems came in the minute I flashed and went away the minute I flashed back to stock. Just curious if anybody else has had similar issues and if you found a resolution.
Lots, including some of our development cars. So you'd want to evaluate your specific logs to see what's going on there.

We do what we can to help everyone. But, we're not MHD flash support. We provide FREE maps that are intended to be used in conjunction with the JB4 tuning tool. In most cases what we provide is more than enough but if you have special needs or requirements on a tight timeline then hiring a custom tuner to help you sort through whatever you are trying to do is probably a good idea.

Thanks all in advance
1) It's on the user adjustment page and does what we said it does in the first post. Tells the JB4 you have a BEF map loaded.
2) What is your software version?
3) MHD suggested we inform customers to flash that way, but if the flash loaded and car starts after, it's probably fine
4) In that case would best to start with Map0 to disable the JB4 all together.

PWG is a unique case and since the vast majority of F series are EWG, we ask PWG guys to ask their customers in the PWG specific thread to avoid customer confusion: http://www.n54tech.com/forums/showthread.php?t=47223

To answer the question though on map0 you'd also put the boost solenoid connection to stock, to fully bypass the JB4, with PWG ISO.

Martial, where are we on disabling the PWG boost under target code? That false alarm code is a huge annoyance for our PWG customers.

Not sure if this would be a question for you Terry, or Martial, but is there a way to code out the MAF sensor for those of us that run with it disconnected. The only reason my CEL light is on is the MAF being disconnected.

By no means did I expect to be a special case, I just haven't seen much talk about PI looking through the thread and was polling for other experiences.

Since I've been running without the BEF I have noticed some of the same symptoms although much less drastic. So if anybody saw my post and started questioning their purchase, ignore it Time to start throwing money at my car until it works right.

Thank you.

I’ve been using BMS E85 bef since release. It’s already faster on uphill going street with full weight than it was on drag strip using ACF flash.

Have to update the signature... :D

Not yet but I've been bugging Martial to figure that out as well as the under boost fault. Hopefully, soon!

Terry or someone at BMS.
It seems as if you have changed the trim scaling with the MHD-flashes.
Previously with the stock software trim over 40 was maxing the fuel pump which would cause the car to start going lean.
What value should i look for on the trims with the Race BEF?

Trims should fall between 0 (-33%) and 50 (+33%) to avoid effecting AFR targeting.

First link is before BEF and second after/with your race BEF.
It even shows signs of running "lean" when trims are hitting 10-11.
So if what you wrote is correct there must be an issue with the BEF you are providing..

I know this will probably get Zero replies. But does the MHD flash remove the overrun/burble when vehicle is in park.?! For wth reason it does not function on my car. With MHD flash JB4 stack, even when all burble options are at max and rpm at zero. Thanks

Mine has those with E85 bef when dtc is off. Havenít enabled them in MHD app and would love to get rid of them. After all itís Bmw, not Honda Civic.

Sounds like you're just confused. Obviously with the BEF we adjust the fuel trims and AFR targets. Logs in the link look as mapped.

If your trims are sticking at 50 or 0 then may want to make an adjustment. If not then AFR targets are as mapped within the BEF. Is there a link to your specific log with the "problem" you want me to look at?

If your question is why do we run the N55 motors so lean it's because the fuel pump is weak and can't maintain pressure well at richer targets, and due to DI the motor tends to run better leaner, in our years of experience tuning it.

Which version of the MHD app are you running? The initial public release had a bug where burble effect would sporadically stop working. An update has since been released that fixed the issue.
