Puffwagon Posted August 23 Share Posted August 23 You don't need to log it but if you were to log it you would look at "spark total advance". Progressively lower numbers in the decel table will go from no decel noise, to a bit of a rumble, a bit of popping, lots of popping, a fair bit of loud banging and popping to machine gun like banging. Start by chucking 5 degrees through most of the table and see how you like it. Make 5 degree changes to see where it needs to be, then adjust it by a couple of degrees if you feel like it. You will need lower numbers at lower rpm for the same effect. You want it to return to normal around 1000rpm otherwise it will keep running lowered timing and might stall when coming to a stop. You need to let the fuel keep flowing on decel for there to be any explosions and this is changed by adjusting "Minimum DFSO time delay seconds" to as many seconds you want the pops to last for, providing the car is decelerating of course. If you wanna decel from a couple hundred clicks then set it to 20 or 30 seconds, it doesn't really matter. That is the basic run down and should help anyone get their car making some noise. 1 Quote Link to comment Share on other sites More sharing options...

Roland@pcmtec Posted August 30 Share Posted August 30 Also E85 vs 98 tends to "crackle" differently. So if you have a flex fuel/dual fuel tune, you want less spark retard on the 98 tune as it tends to be louder due to the flame speed being faster. 1 Quote Link to comment Share on other sites More sharing options...
