BM3 CustomROM is Ready!

[Eastwood]

If we can flash back to literal STOCK to pass the OBD-II check, my ECU is going BM3, immediately. Worth it for the flex fuel option.

Not just that but also retaining the unlock. That’s the only thing that’s kept me from getting unlocked with Femto.

Paying to unlock every two years would suck LOL

Right? That's what made a cloned ECU such a desire lol

I ordered a BM3 flex fuel kit for the A90 came in quick but it didn’t come with any instructions for installation. I sent a message and they asked for my VIN and then ghosted me. I know my way around the car but come on man! I guess I’ll send it back.

You guys could always buy a later model locked ecu for cheap and have it cloned to your factory ecu. Will be a couple hundred more but a lot less worries when it comes to the dealership and smog.

YouTube my friend! But thats weird companies don’t add instructions for something complicated as that.

Trust me, Ive been scouring the Internet for a week nothing anywhere I guess because it’s such a new product?

What are you looking for instruction wise?

Thats unfortunate ;/ yeah Id just return it and get another flex fuel kit and see if theres videos on it.

Anyone know if Fuel-it can work with BM3?

Really looking for the wiring diagrams…the rest is pretty explanatory but don’t want to assume this kit is like some of the others. Any ideas?

Can you take a photo of the wire harness?

For anyone that had run the BM3 OTS maps. Have you noticed a difference between stage 1 93oct vs stage 2 93oct? My butt dyno is telling me stage 1 feels faster than stage 2.

How does that work, not being pre 6/2021 or whatever? I'd DEFINITELY do that.

It works exactly the same as if you were cloning an unlocked ecu, prices and all. Difference is the ecu is MUCH cheaper to buy.

Ah, I forgot we need to be very specific on this site ?
This part is new to me: So post June 2021 ECUs can be used to clone a locked ECU. You end up with two, identical, locked ECUs.
I can then have either one unlocked to run BM3.
So, the only advantage to finding a pre-june 2021 ECU is that you can run different tuning software.
Is that about it?
If so, I will eBay an ECU immediately. All I'm after is flex fuel. This whole testing and mixing to get <E30 business is annoying. Especially since It's just to help the car run a bit cooler. It would be nice to not have to be so exact.
