I am after late ignition timing for a rally style bang bang antilag instead of a spark cut antilag. Everyone keeps saying that using an ignition angle of -10* is too much but the typical rally style antilag runs timing in the -35* to -45* range. They also employ a throttle kick to maintain airflow and enrich the mixture to cut down on egts. (This would be in a system active, vehicle in motion, no input on throttle situation) As far as timing that negative shutting the engine down, it doesnt make sense. If you fire the spark when the piston has begun its down stroke it minimizes torque input but keeps the primary combustion event in the cylinder, valve, manifold area. The spark cut versions dont fire any spark and they dont stall the engine. They push the fuel to wherever it can find an ignition source, be it manifold, turbo, or exhaust from an alternate cylinder. The goal is to have bang bang antilag as an option when I put the turbo restrictor in.
How about you get some experience before stating these things. Everything you're saying is ridiculous.
40 degrees ATDC, absolutely shuts the engine down instantly. There is no power produced. I don't know where you got the idea about "rally style antilag" you sure as hell don't seem like anyone who has EVER tuned an antilag system before. My company does rally cars on standalone and I can guarantee not a single one of them has 40 deg atdc timing.
Not a single modern car has any "throttle kick", e-throttle is used for antilag and air control.
Same goes for 20 degrees ATDC.
Instead of discussing this stuff here and having opinions about shit you've never even done, how about go out and get some experience?
