Thinking about fitting a Gems Ecu to my ex prodrive rally car as the original is Pectal and is not re mappable , are they any good ? Do they have multiple fuel maps and can they run without an afm ?the only reason I'm going or thinking of going for Gems as I can pick one up secondhand for 500.Am I better off forking out for simtek or syvecs ?
