ECU change or upgrade
Discussion
What are you hoping to achieve? Don't think you will get any massive BHP gains all else being equal? From what I gather most might consider if if rebuilding/upgrading to 4.3/4.5L options. Think it is expensive to do so doing it to a standard engine doesn't seem a popular upgrade from what I have seen. Think some people get a different 'chip' or get a remap if they go for decats, bigger bore exhaust and/or upgraded airbox or any combination of these....
Might be worth talking to Matt (M4tti) on the tuscan/speedsix forum who has done a svecs and fff head on his own. Reliability and drivability are the main advantages, the original MBE is quite antiquated with batch injection, no idle control and some reliability issues. Have a chat with him he is a great guy and will tell you what he has done.
