Also asked this on Facebook.
I use a KL05 ecu and KL02 vaf.
Near Throttlebody VRIS doesn’t open
Distribution side opens immediatly
When I switch the wiring plugs, the vris works the other way around. (so solenoid is ok)
When using a different ecu, tested KL36 ecu and K803 ecu, both vris are opening (obviously on wrong RPMs).
Even bought 2nd ecu, kl05, same problem as my first ecu.
I also switched another KL02 vaf, still the same problem.
Who can help me figure out where the problem is of the 2nd vris not working?
