2WS ecm on MBN?

Yeah we have it sealed up and in an old trailer so we'll keep it around for a while. The MBN really doesn't pull that bad considering it's only a 475/1650 engine but the fuel mileage is killing me. We almost repaired the 2WS but everything was worn out on it and the MBN had a year old CAT rebuild with papers .

 

Thanks for the info guys. I took the 2ws ecm off my old engine tonight and will try and get it on Thurs.

 

Only for the last 7 years

 

Whoops l misread your question. Sorry about that. We did use the mbn ecm that came with the engine. I did get it reflashed after about a month or so. It was running ok and everything worked. It just ran like a typical mbn. Hot and lazy and crappy fuel mileage. The guy that reflashed it used my 2ws ecm to set the baseline settings in the mbn and upgraded the files for better performance and cooler running and fuel mileage. Like l said everything was working ok before so maybe it wasn't necessary but I'm not complaining if he wanted to cover his ### in case there was issues down the road. As l said its been running on that ecm for 7 years now. I finally sold the 2ws engine and ecm as a core for a glider. Still think that was a mistake guys think 550hp ecms are made of gold nowadays. Sorry about the mixup.
