Hi, I have E36 m54b30swsp with ms43, but the engine rev is limited to 5500 , where is the problem?
But sometimes specially when engine is cold it can rev higher
Thanks in advance

You're missing vehicle speed signal to DME, so it goes into diag mode. Or any other missing signal. Very common of these swaps.
You need a proper tune. Very easy to fix if you know what you're doing.

Thanks, its my first, sorry, but can i fix it without ecu tuning?
You don't have to be sorry (I hope you didn't take it as me being offensive).
I don't think you can easily fix it without tuning. But the tuning isn't too hard. That was my point. If you pull the partial flash from the MS43, I'll do it for you.
