Cam raw not changing
Posted: Thu May 03, 2018 10:24 pm
Hi,
I have a problem with 720 sync on an Evo 5 with a Mivec Engine. Car has an 18-1 crank trigger, the standard cam triggers and had been running ok on its first event after upgrade (albeit with low boost).
Exhaust cam (phase) utilises Analogue input 06, and Mivec Cam utilises Analogue input 03.
I noticed we had lost 720 sync and noticed the cam raw was not changing as it previously had.
Sync log shows good cam phase signal, but cam raw remains steady when viewed on guage and on datalog. Can this be anything other than an ECU problem??
I have tried swapping inputs and both cams give good signal when connected to input 06, but no signal to input 03 suggesting wiring or ECU issue with input 03.
I have also tried disabling the Mivec function (taking Input 03 out of use) and still Cam raw on Input 06 does not change.
Anyone have any ideas??
