Hi.

Are the settings for engine type 47 the ones to use? (crank primary, no secondary and vvt on the cam)

i get 1/2 commanded RPM displayed in console ? vvt angle does change if force random inputs on the cam input but it isnt clear if the simulator is giving out any triggers on the cam channel?

i will try and scope it tomorrow and see

At the moment trigger simulation logic is not aware of VVT

In case of Miata VVT the work-around is a special trigger only for simulation but it requires two rusEfi instances - one running TT_MAZDA_MIATA_VVT_TEST trigger just to produce both signals, the other to consume signals

thanks for quick reply!

im reasonably sure i can just connect my sensors now and see what comes out the other end :)

i was going to use an mpx4250 for map but it would need stepping down. does there exist a MAP sensor that runs on 3.3v ?

Want to start a thread about your car with pics and stuff? MAP sensor voltage is offtopic for "Miata VVT trigger sim" thread. Sorry for my kind of crazy :)
