Hondata

Installed a Hondata S200b with dataloging. After the installation everything works fine with the exception of no speedometer, no VTEC, no back up lights and the radiator fan is not coming on. Didn't have this problem before installing the Hondata. I checked all sensor connections, fuses, relays and ground connections and can't fix the problem.

Please note that when dataloging wiht the Hondata i do get speed readings on my laptop.

Can this be a Hondata issue? If not, any suggestions as to why should i check next.

The car is a 99 Civic Si with a JRSC and a P28 using an adapter harness.

if you put your old ecu back on ... do your problems go away ?

Yep, with the old ECU (P28) using the same adapter harness i'm currently using i do not have this problem.
