So you want to say guys, that my DMTL pump error (2A13), and possibly thermostat error (2EF4) are caused by BMS flash (via MHD)? I have got worse consumption too (by 20%) but thought it is the reason why my car is so fast lately

Im currently only getting 15mpg currently with the e85 flash
But your right about the fast part

I also have faults; DMTL (2A13) and thermostat (2EF4) since I flashed Pump and increase fuel is horrible
Please add option European cars.
Thank you.

Just went and purchased a tablet, cables, paid another 100 for MHD software and flashed my DME and it's now running the worst I have ever seen it.

Got misfire on cylinder 4 and lambda probe errors.

Something doesn't play nice between the JB4 and the flash - and there are no clear instructions to follow.

I have set all AFR bias to zero in JB4, set 4 for I8A0S logging, selected menu 4/2 in dash controls, and tried maps 1 and 2.

The car does not boost well at all, even stuttered and began vibrating heavily. I've ran JB4 standalone for the last 6 months without so much as even an error code.

Previously with just JB4, I've run 98RON on map 2, and up to 30% E85 on map 5 with great results.

What is going on?

On a side note, every time the JB4 interface is updated the settings and descriptions become even more convoluted and ambiguous. There is no thread or instructional on the settings that need to be tweaked for changing from piggyback to flash, and the previous CPS settings have now changed to Duty bias?? err what?

Guessing user error or hardware issue... Provide more info, map used?? Fuel?

got the same exact issue when i tried siwtching different flashes. before, i had the e85 backend flash and it ran great but a little too aggressive for my mods and sometimes i would get limp mode. im on the pump flash and my car doesnt build much boost ,if any ,at all

[Scotty89]

Using BMS pump flash, modified with tuner pro for European car.

Fuel is 98 RON, using maps 1 and 2 from JB4.

There are no "reset to default" JB4 settings, and there are no instructions on which settings require elimination for running a flash.

[AWil335i]

Are you running the most recent updates to the flash and JB4 firmware? Pics of your settings and logs would be most helpful.

[Rushan]

I got my cable and installed the MHD, connected to my ECU and read and backup ECU, my HW showing 7611358?! My ECU should be MSD81 but why I get this 7611358?

Any hints or advice?

Rather than this description of the issue which takes a long time for you to type, and is not possible to troubleshoot with, why not post a JB4 CSV log which takes only a few seconds to attach?

The exact codes would be good too.

It is better for AT cars and upgraded turbos cars. Differences will keep increasing.

Faulty cables-phones can only result in failing flashes. A successful flash cannot be different than another. You need to post in the support section with details to get help.

Either you use JB4 for boost control with a BMS back end, or setup the jb4 as passive to run MHD maps.

No responses or acknowledgement to EU required maps?

Are US customers your only customers Terry?

[ba114]

it seriously takes a matter of seconds/minutes to covert the changes onto a copy of your own stock rom.

There are instructions on how to do this already using tunerpro. Personally i think everybody should be doing this anyway. I want the undefined data in my ECU to be related to my own car, not somebody elses.

Our JB4 back end flash maps are provided free of charge for you do with as you please. Run them as is or use them as a reference to make your own BIN. That is entirely up to you.

Where are these instructions? Having no problems with the canned flash but sounds like a nice read.

I'll knock up a quick and nasty How-To thread.

[Terry @ BMS]

Thx! The only catch might be the XDF files. I'll be sure to update those on the open flash thread shortly.

This may be your approach, however your customers are worldwide. And you're only releasing a BMS flash for USDM vehicles. The only other variant is EU which addresses the rest of the world when it comes to a different DME variant.

You are an engineer and tuner by trade, a respected expert in your field and product you provide, obviously your customers that are located outside of the U.S. Would like a simple EU file which shouldn't be hard for you to do at all.

You would think (from your response) that we're asking for your backend flash to work on a procede or some other piggyback....but we're asking for this to work on your own product. Lol

You are awesome Element! Totally not your prorogative to do, but doing so to help out the EU/APAC/OCEANIA regions!!!

I don't have my car back, but hopefully one of the other EU boys can test it out.

I'm not aware of any significant issues using the canned flash map on EU cars. If you want to host a thread with the details I'll see if we can accommodate changes for it.

The idea here though with these back end flash maps is you'll take the base map and do with it what you will. Be it flash it directly as the 90% do, port it over to your BIN, modify it, etc. It sounds to me like you have an expectation gap on what is being provided.

The flash isn't a BMS product. It's a free, unencrypted file and the instructions to modify it are readily available. I understand the frustration, but from a business standpoint, their effort is better spent on improving the products they make money off of. If you are willing to pay, I'm sure someone could cook one up for you. Or better yet, start hittin' the books and you could be the guy!

What tables are missing currently? I have some updated xdf files but I don't know how recent. Would be nice to get the latest and greatest. Please post a note when updated. Thank you

[Bullitt1841]

Can't find any info anywhere. It seems with these flashes I can't get the JB4 to force the CANflap closed. Is it set to be open all the time in the flash?

[Rushan]

Any idea how to get ride of the code 2FA3 Coding missing after flashing back to stock?

I have a 535 but on my car. 4,4 and 4,5 are reversed for some reason.
