i far i can see from your map file the VVT control is OFF....so your mapper has wired in vvt solenoid in auxiliary output 6 without using cam trigger...i guess the vvt now works as an ON/OFF mode and not as constantly variable timing as it sould be and it just change position from fully open to fully closed and vise versa...it can not get middle pisition as it sould be The old bmw VANOS systems was ON/OFF... in your case probable the problem here is that the vvt changes the camshaft timing too much degrees as i said it only gets 2 postions fully open or fully closed...maybe it changes 20 or more degrees and that cause your problems... my advice is to use proper vvt configuration with camshaft postion sensor or KILL the vvt totaly and find a correct timing for your camshaft specs...i prefer the second method as its more simple and you can achive higher dynamic compression and great pulse tuning on the intake as the camshaft timing will be stable and always the same (as far the timings it make changes the pulse inside the intake will not be never be cordinate)

except filtering you should use very good quality screened wire on this kind of sensor also Trigger Arming Threshold has major fact on magnetic interference

thanks for the quick answer...just check the manual about differential trigger on kurofune...ok thats an option...or i can go totally standalone with just link ecu wired up...and i will use aftermarket rpm gauge but now the problem is that subaru 1-6 trigger pattern cant work without cam signal....so i need to wire up cam trigger too, i think its the same too with subaru cam trigger...i need to check

Hello i am new to link ecu's, i am experienced but on another ecu brand...i have a couple of question about trigger type and trigger signal i am building a Fiat engine that trigger pattern on crank and cam is the same as subaru old models...thats why i am thinking to go for a link ecu i post a crankshaft image from the fiat 1) is it possible to run subaru 1-6 trigger setup but without the cam signal ? (i just want to keep it simple with wasted spark and batch on injectors) 2) is it possible to share the signal from fiats reluctor crank sensor to both fiat ecu and the link ecu as i want to keep fiat ecu to run the dashboard with the canbus etc ?
