baker402 Posted May 6, 2012 Share Posted May 6, 2012 hi on the weekend i installed a apexi vafc unit to my mb6 but i have noticed the revs on the vafc is 500rpm less then the one on my speedo . so when im at 6000rpm on my speedo on the apexi its saying im at 5500rpm which is putting the vtec out any ideas why this is happening?

knight Posted May 6, 2012 Share Posted May 6, 2012 Speedo is proberly out not the apexi as that reads straight from the ecu. Quote Link to comment Share on other sites More sharing options...
noodels Posted May 6, 2012 Share Posted May 6, 2012 thats along way out, any chance to calibrate revcounter or swap with another to get real true rpm could it be the apexi at fault?edit as above Quote Link to comment Share on other sites More sharing options...

baker402 Posted May 6, 2012 Author Share Posted May 6, 2012 i had it fitted by a auto electrician so cant see why its not reading right but i can most probably will be able to get hold of another speedo to try Quote Link to comment Share on other sites More sharing options...
