need help with a buck issue VEMS

Postby shark_22 » Thu Aug 27, 2015 9:58 am

Hi, we have some bucking issue with my vems and its hard to find the problem, so if somebody already experiment something like this or have an idea of the cause, will be appreciate to have your help!

It happen at different throttle position, always the same duration but different intensity(depend on the throttle). Never 2 buck at the same time, its one after the other at different moment.

Its like all 6 injector ou all 6 coil stop at the same time. No trigger error, nothing special in the trigger log/log.

I re wire the hole grounding system like vems want,re wire the crank and cam sensor just to be sure, and still the same problem.

Its hard to see it on the log, I got one that i provide where we see it at the end(rpm drop and goes back,same throttle pos.)

it start at 2min44

Engine:subaru h6 ez30r avcs-vvl, tuned and run very well (but got the buck issue!)

thanks
