I have UTEC and Tuner.. ant I can get a log of A/F with rpm from UTEC's log but if I switch to Tuner display to look at Tuner's log, the RPM stays at zero?

Anyone got the same issue?

Maybe I should try disconnecting UTEC from Tuner and see if it will work properly then..

 

Disconnecting the tuner from utec would make the tuner a stand alone at that point (and it won't be able to see anything except AFR, no RPM)...

When I first connected mine together, my utec wouldn't see AFR, but the tuner did.... After awhile, the utec just started "seeing" the AFR from the tuner... Wierd. And has worked ever since.

So I guess my only advice is to just fiddle with it til it works. Remember the utec needs to be fully booted before the tuner comes on line... Or else they do wierd stuff like one not seeing RPM.
