Does anyone know if there's a free utility to flash a modified BIN file for an N54 DME? I'm looking to load a BIN that has the 29F4/5 DTCs disabled for aftermarket downpipes, and I don't want to load any sort of modified performance tune to do so. Basically want to keep the ECU stock, just suppress the DTCs thrown by the DPs...

Ie. Like BMW Flasher for E46 M3s.

Does any such option exist?

Edit: Well I successfully flashed it via Bimmerlabs and WinKFP! Can confirm the 29F4 and 29F5 codes were disabled (along with 2FA3 for good measure). However, the "stock" IJE0S file I downloaded and worked from did not seem to be stock. The car was making way more boost/power and immediately threw a few misfires on the first pull. Flashed it back to a factory ZB file via WinKFP for now.

Does anyone have a stock IJE0S binary file from a 335i (not 335iS or Z4) then can share?

Don't know of any free DME flashers that allow custom flashing.

I bought MHD even before I went stage 1. Was running stock tune with MHD installed. It's handy even if you are running a stock tune, for logging/monitoring DME parameters.

You have downpipes and you want to run it on a stock tune?

Why didn't you keep the stock downpipes?

If you ever flash a tune, you won't want to revert back to stock tune.

You can use the Bimmerlabs RSA delete:

Lets you flash custom files with WinKFP.

Depends how comfortable you are with coding. The MHD flashing license is cheap and will let you delete cat codes and cold start within the app.

Can't see anything about N54 or MSD80 listed on there,

Are you sure it allows you to flash custom map on a N54 MSD80/81?

I’m confused as well to why you would run aftermarket DPs and a stock tune...

Yes, has a tool that allows you to convert bins into 0da files for flashing.

MSD80 and MSD81 are supported.

Not everyone wants to power tune.

Some people install catless downpipes just for a louder exhaust sound.

It should spool a bit quicker too, even without tune, and probably a better turbos life (less backpressure).

What about the BB flasher?

Thanks! Just saw that Bimmerlabs shows support for MSD81 and I converted my modified BIN back to a 0DA. I've used their SW in the past with great success. Will report back with results if this does the trick

To others: I am doing the DP mod for sound, that's it. This is a family member's car that's otherwise bone stock and has been for years, with keeping it reliable the biggest priority, not extra performance.

Way too unstable from what I've read. Failed writes, bricked ECUs, and sometimes doesn't even run on Windows 10...

Downpipes make a significant difference with a tune, without a tune its marginal gains if any.

Ok, but WinKFP requires someone who knows what they're doing. Could cause a whole load of issues otherwise.

When i first got my downpipes installed, without making any change on the present tune, on my way back home, i immediatly felt a quicker spool or better throttle response.

That said, i didn't speak about power gains, but it spooled better and that was noticable, so i guess on the stock tune that aspect should be noticable too because of less back pressure.

Just my own observation.

I mean, it’s free... buy MHD FOR 80 bucks and stop being a cheap ass. It’s the best in the business by far.

Bimmerlabs is not really that hard to use.

All of the flashing uses BMWs WINFKP which means the process is very safe. It's all scripted through batch files, so you really don't need to know that much.

Probably done 100 flashes through the Bimmerlabs and never had one fail that was not my fault, bad cable, stupid tune etc.

Never liked the idea of a vender changing the access keys and locking me out of my own DME. Bimmerlabs does not do that, everything remains open.

WinKFP is pretty foolproof. Besides I've been doing coding on these cars longer than most people have owned their E90s on these boards, so I'm not worried.

Yes you'll probably feel a difference, I wasn't saying you won't. But the difference is small compared to having downpipes with tune.

I don't see the point of spending money on downpipes and not getting a tune. If owner doesn't want to tune stock catted downpipes are fine, backpressure at stock tune was never a issue.

But each to their own.

is there a guide on using it?

He said he did it for exhaust sound.

Less backpressure is always better IMO.

Well he's missing out on the performance, and it's quite a major performance difference between stock and tuned, even if its just stage 1.

Does anyone have a stock IJE0S binary file from a 335i (not 335iS or Z4) then can share?
