i'm trying to do a little bit of antilag using the map. i'm not sure who had succeeded on this portion of venturing. i used to run an ECU that's tuned by FEED. it's still with me. amazingly it has anti lag built in....

it reduces the EGT quite significantly when deceleration. but in return.. it'll make the bumper really dark by giving misfiring on deceleration.. alot of back firing...

i'm trying to tune my PFC to mimik that kind of situation, i know that by bumping fuel into the N17:N18 P16:P17 will give alot of backfire.. but it's not right.. it'll rob alot of power away.... i tried doing it on a Toyota MR-s, and found out that it can be done by adjusting N16:N20 P02... that's the part where the Injector duty cycle almost got cut off....

anyone able to force the injector to switch on around P02 or P03 during deceleration? when decelerating, the map jumps too fast.. unable to read anything between the high load high rPM and the deceleration P02 row... while P02 row are all 0 for injector duty cycle.

any solution ?

 

dude......... you got it all backwards , decel fuel cut reduces EGT (during decel)

 

oops... :P my bad....
aren't the dumping fuel in the rotor housing during deceleration cools the rotor up ?

 

People, look up the real definition of backfire! Most people use the term wrongly.
You are talking about afterfire or afterburn.

The PFC uses the the 3 fuel cut values to set the not throttle change rpm when the injectors start working again. When you lift off the throttle, the ecu cuts off the injectors until you get back on the throttle or the rpms drop to the set points.

If you set the 3 FC rpm values at 9000, there will not be any FC and you will have all the flames you want.

It is used as a way to save fuel. If you defeat it, then the engine still gets fuel but with a close throttle.

 

If there's no combustion (because there's no fuel )then there's nothing to cool. Buy a EGT gauge and you'll see what I'm talking about .
