We have a Maxisys on a Acura 2002 model MDX and it is showing over 5,000,000 engine rpm. Also it is showing over 20,000 on the fuel injector pulse.
I hook up my Maxidas (WIFI disconnected so AUTEL won't lock up my scanner ! ! Yes it will lockup your scanner, just check in the Maxidas forum section ! ) and it reads normally.
Something is drastically wrong in the software for the 2002 Acura MDX !
