2 cars - 1 m400

[extonson]

I am considering a m84 so that I don't have to swap ecu and file when I want to use either car - question is will the file from the m400 go over to the m84?

It is a NA 13b rotary with a s4 cas.

I would like to know for sure before I spend my cash.

You cant load a hundred series config into the M84 manager and there is no utility provided to convert the entire M400 config into a M84 config. However it is still not a big task - you just need to open both the M84 & M400 managers up side by side and manually copy the settings. For tables like the ign & fuel maps you use the 'save table' and 'load table' functions.
The inputs are a bit more locked down in the M84 so you might find that you have to shift a couple of pins around in the connector but if it's a basic rotary install it will probably be fairly straight forward.
