I have IQ3 display dash with a xfi 2.0 interface, the issue im having is the rpm sweep is delayed, I have tried changing the filter under the dash rpm, that did not help, I tried changing the raw data B 1 will become 1 thru 5 and that helped a little bit but anything over 2000rpm it gets delayed more and more, Is there anything else I can try?? everything else is working fine just the RPM is very delayed and lazy, or do you think there is a issue with this dash?? Thanks Todd..
