paulr33 Posted May 24, 2015 Report Share Posted May 24, 2015 hi team, looking for some help on my evo 8. car stalls or nearly stalls on hot start but usually recovers ok, just annoying "rev drop" that id like to try and tune out. ive had a go at logging and trying to adjust the idle table as per below in red highlight to increase timing here in an effort to reducen the variance across the table when warm, but it still seems to almost stall. can you suggest what im doing wrong or how to reducen the stall zone ? logs are here; http://www.paulr33.com/evo/stall.zip Quote Link to comment Share on other sites More sharing options...
paulr33 Posted May 24, 2015 Author Report Share Posted May 24, 2015 This is where i think its getting into trouble, marked in blue Quote Link to comment Share on other sites More sharing options...
paulr33 Posted May 24, 2015 Author Report Share Posted May 24, 2015 i thought about this some more and do i need to do a combination of stepper motor % increase, adjust RPM to be a bit higher and adjust IGN timing error table to compensate?

max Posted May 25, 2015 Report Share Posted May 25, 2015 the idle ignition table looks a bit busy you could remove the y axis altogether to simplify things. on a side note how do you get the screen up with the list of all the different functions where you have highlighted your problems in blue Quote Link to comment Share on other sites More sharing options...
paulr33 Posted May 26, 2015 Author Report Share Posted May 26, 2015 thanks, you are right, i could simplify the table but thats how it was tuned and given to me from previous owner / tuner. the data in colours and with blue boxes is an ms excel dump of the logs and then using the MS excel "colour bars" function Quote Link to comment Share on other sites More sharing options...
paulr33 Posted May 27, 2015 Author Report Share Posted May 27, 2015 would a combination of adjustment of solenoid duty %, increase in idle rpm and adjustment of IGN timing ramp for idle help correct/curb this? Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted June 5, 2015 Report Share Posted June 5, 2015 Hi paulr33, I always use a combination of throttle blade air gap and idle ignition timing table to control my idle and idle load quality. Please find attached an example idle ignition timing MAP I would normally use. Give this a try and report what happens please. Regards Dave.

paulr33 Posted June 6, 2015 Author Report Share Posted June 6, 2015 thanks for the reply, so basically a 3d idle map, will see what i can work out Quote Link to comment Share on other sites More sharing options...
