hi guys, i recently got a vtec controller apexi vafc I for free off my family friend,
i've installed it accordingly to the instruction i found on the net, works fine, everything seems to be in order, but i had a slight problem,
the rpm on the vafc shows lower than it is on the cluster,
for example, cluster shows 2000rpm and vafc shows 1356, the higher the rpm goes, the bigger the difference is (3000rpm on cluster and 2100rpm on vafc)
anyone know what could be the problem?
Thanks and please dont flame.. I've searched the forums but cannot find any required information in regards to this topic.
Thanks
car is stock honda civic eg9 sedan vti, manual. P28 ecu
