what is the activation rpm on kpro? my activation rpm is set at 12500 for some ridiculous reason from when it was tuned. when i went to burn out at the track my redline is set at 9200 but the rpms jumped to way about that. i know the activation rpm is suppose to be set somewhere under the two step point, but i was wondering exactly what it does?

also when im driving and around 2-4000 rpms my car will jerk back and fourth a little sometimes. is this the air/fuel ratio? if so how could i tune it myself?

sorry for the noobish questions.
(this thread is on k20a.org i just wanted to see if i could get more input)
thanks.

It's called MAP cut.

 

map cut? and sorry i dont mean a little, sometimes its like whiplash..

 

was she dyno tuned?

 

kind of seems like a problem people have when attempting to "street" tune kpro.

 

What are your mods? You dont need to worry activation rpm unless you are turboed. Who tuned the car?

 

tuned a while ago at rrev motorsports (dyno tuned). the car is in a different area an elevation now so i think its the air/fuel.

but with the activation rpm, would that allow the rpms to jump so high past the redline set when doing a burn out??

Again what are your mods? The activation rpm is used for antilag purposes. At a complete standstill rev limit is controlled by the Launch Rev Limiter. Once you exceed 3 mph the rev limit is controlled by Overall Rev Limiter.

so how can i adjust the rev limit when doing a burnout to not go that high?

 

Datalog and check your A/F ratios. Like I said at a complete standstill rev limit is controlled by the Launch Rev Limiter. Once you exceed 3 mph the rev limit is controlled by Overall Rev Limiter. What are these values in your kal?

 

what are good a/f ratios?? at the time the rev limiter was set at 9200 and during the burnout the rpm tach was jumping higher then that..

i datalogged it today and it is my a/f causing it. i will upload it later. but its only sometimes in the lower rpms. 2500 and under usually. also i ran it up through vtec in 2nd gear and a/f was fine but the INJ was at like 10.19. is that normal???
