So I wanst ever planning on posting screenshot in this thread, but his deal with removing pilot and getting white/blue smoke is really getting at me.
Below are a stock main timing and stock pilot timing tables. as you can clearly see with the main timing, the (-) values are injection timing ATDC and the regular values are timing BTDC. Pilot is referenced from main timing.
So if you look at the first cell on the pilot table 0mm3@650rpm=13.0 degrees of timing before main timing. Main timing in the cell is -3.0 degrees which translates to a total injection timing of 10* BTDC at 0mm3@650rpm. Remove that pilot event and your firing the main event at 3*ATDC. which can and will always cause a unhappy engine.
Looking at it further at say 2000rpms and 55mm3 which will translate to medium throttle and 2000rpms...with pilot active your total timing is .5*ATDC on main and 28.9*. Take pilot away and your running again your main event ATDC...never going to be a happy engine like that.
My real point is that unless Marco can rescale the main timing values to compensate for pilot loss...its never going to work properly and can have very adverse conditions.
First is stock pilot timing.
Next is stock main timing...
Again the point of this post is not to bash the SSR product or Marco's hard work...its main focus is to help people undesrtand why their vehicles act as they do when pilot is taken away.
