  • Upgrade DF90 to DF115 by changing ECU

    Hello, can anybody tell me if it is just plug and play if I change ECU on my DF90 with a ECU from a DF115. Will that work?

    Possibly, but cams are different part numbers, so valve timing might be different, negating a lot of what you might expect to gain. I have no knowledge of the cam specs of either motor. Everything else appears to be the same, but valve timing plays a huge role in output. The fuel injection mapping and ignition timing programmed into the 115 ECU might not be very compatible with the 90's cam profiles.

    So I'd say it's possible it'll plug right in, but I have my doubts as to the desired results.
