i have used megasdquirt ecu's on rs turbo engines and the 24v v6 cossie engine and the all worked fine. You need a little knowledge to do the wiring and i suggest you creatre a new loom rather than modifying yours as if the MS ecu fries/dies then u will be stuffed...
Check the megasquirt website for all the info.....

And as for the code being basic...wtf it works well on any engine and has more adjustable parameters than many of the leading aftermarket ecu's at a fraction of the cost!
go 4 it m8y!
