ebc rpm duty compensation not working

jpjackson · Post by **jpjackson** » Tue Feb 16, 2010 10:00 am

whats up guys, i am trying to use the rpm duty compensation table to compensate for boost creep by lowering the duty cycle per rpm, i am still running a fixed duty and closed loop is not enabled, is that why it isn't working? do i have to have closed loop compensation on for it to work? or do i have to have boost by gear enabled?

It cant be on fixed duty cycle, or it will be fixed duty cycle. Boost by gear will work. It took me a while to figure out all the controls for the EBC to.

ok, sweet, i got her working. i set all of my duty lookups roughly and set it to gear based boost and it is working great. thanks for the help guys.

ok, i have set up boost by gear, enabled and tweaked closed loop compensation, and tried tweaking the RPM duty compensation maps, but the RPM duty comp doesn't seem to work. so it isn't on fixed duty any more, so do i have to have it set on boost by RPM for the RPM duty compensation to work? i thought the duty compensation tables were for general compensations like the IAT compensation, or does the closed loop MIN/MAX settings have to do with that? i.e. in order for the RPM duty compensation tables to work, it has to be in the closed loop MIN/MAX adjustment range? i.e. if i only have 4% to -4% adjustment on the closed loop settings and i am trying to pull -10% at 7000RPM to compensate for boost creep, closed loop correction is only going to allow that + or - 4%? sorry guys, i am just trying to get a better understanding of how the closed loop and duty compensation tables are suppose to work and how to set them up. and one other thing, what is the target boost TPS multiplier do and how to set it up, i think i read that you can set it so that your target at 100% TPS is 10PSI and 50% TPS would be 5PSI. is that correct?

things i am trying to figure out, how they work, and how i am suppose to set them up? does RPM duty compensation work by its self or does closed loop compensation have to be enabled and set properly with enough range in the duty adjustment to achieve the -10% duty i am trying to pull at 55k to 75k RPM to compensate for creep?

I couldnt help ya here. I dont even use closed loop as it doesnt want to work for some reason on my setup. I went out for 2 hours trying to figure it out one day to no avail. I just use RPM compensation on gear based maps.

rpm duty compensation doesn't seem to work, playing back my logs it doesn't show that it is pulling duty at the certain rpm. closed loop works for undershoot, but not for over shoot. i am still playing with it though.

correct fixed duy is only to setup the psi vs duty table
