B5254T Immobiliser issues


Recommended Posts

Hey everyone, greetings from France

I just discovered this forum through the Motronic 4.4 tuning thread and I wish I had found it sooner haha

Anyway, here's the deal : I am nearing the end of my engine swap which is a B5254T (from an '97 850, Manual LPT 193hp, Motronic 4.4) in my 740 Wagon. When trying to start it, it started right up, ran fine for a whole second or two, than died right away. I'm pretty confident I have an immobiliser issue, which I hoped this engine didn't have but here we are.

I was looking for somebody to do an immo off on my ECU, but then I found out there's a ton of ressources to do it yourself, so I thought I'd give it a shot.

However, I can't find a LPT 193hp .bin file with immo off, so I was wondering if anyone knew where I could find one ? I found plenty of HPT .bin files, but I'd rather just stick to flashing the ECU with an immo off .bin rather than messing with other parameters to make a HPT work for a LPT.

Bit of a mouthful, sorry about that. I'll add a few pictures of my project to make it more interesting 😆

 

Thanks in advance !
