richardpalinkas Posted May 13, 2019 Share Posted May 13, 2019 Is there a way to have an antilag feature for deceleration conditions? Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted May 14, 2019 Share Posted May 14, 2019 Yes. Disable closed loop fueling and DFCO. Set the 0 -> 0.2 load cells to 0.5 lambda, decel spark to -20 degrees etc and then set the minimum idle air in gear at high rpm to high number so the throttle doesn't shut. You'll need to play with the timing and fuel to stop throttle hang but it is 100% achievable. Quote Link to comment Share on other sites More sharing options...
richardpalinkas Posted May 14, 2019 Author Share Posted May 14, 2019 (edited) Can you have this active at say above 3000rpm only so it's still drivable on the road under normal conditions? As in only have open loop fuel above 3000rpm and closed loop under 3000 rpm? Edited May 14, 2019 by richardpalinkas Quote Link to comment Share on other sites More sharing options...

Roland@pcmtec Posted May 14, 2019 Share Posted May 14, 2019 If you experiment please post up your results and what settings you played with. It would be very interesting to see! Be ware of heat though, could quickly destroy cat/exhaust/turbos if you went overboard. We killed an old stock turbo using launch control with -20 degrees timing testing here.

richardpalinkas Posted May 14, 2019 Author Share Posted May 14, 2019 For minimum idle airflow in gear, use auf0030? Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted May 14, 2019 Share Posted May 14, 2019 Yes I believe that is the best bet. Be very careful as if you make it too high and you are in gear it will be like cruise control is stuck on. Make sure you are testing on a dyno and can put the car into neutral if required. I'm not sure if the gearbox will stop you pulling it out of gear above a certain load, so increase it in small increments only. 1 Quote Link to comment Share on other sites More sharing options...

richardpalinkas Posted May 20, 2019 Author Share Posted May 20, 2019 I haven't had a chance yet. Will test within the next couple of weeks and let you know how it goes Quote Link to comment Share on other sites More sharing options...
BarraDrifter Posted June 20, 2019 Share Posted June 20, 2019 Did you ever get around to testing this richard i would be interested in seeing how you went with it. Quote Link to comment Share on other sites More sharing options...
richardpalinkas Posted June 20, 2019 Author Share Posted June 20, 2019 I still haven't had a chance to test anything yet. Been flat out with other things as of lately. Over the next couple of weeks I will start to experiment a bit with it. Any findings that's positive I will update in here Quote Link to comment Share on other sites More sharing options...
