Neutral rpm limiter doesnt work

[billybob]

06 with manual, wanted to use neutral rev limiter to help with staging at dragstrip but number value I entered makes no difference

Try setting ref1 to 2000

Does reference 1 thru 4 refer to what gear the truck is in? Also kinda along the same lines to get the "hard limiters" to work do all the PID controls need to be set to disable? I want to see 4000 rpm but the ecm decides that 3200 is enough lol. But I do have the "P" control still enabled.

Well its not the ref1 setting either, when I used that setting it limited in all the gears. Yeah, disable your p control, should have no prblem hitting 4000

I also changed ref1 setting to no avail....Also I changed the "p" control to get it disabled. After those changes the truck sputters and does some strange stuff down low.....Possibly now that there is no PID control I need to ramp in fuel rail pressure a bit slower? Mind you this tune has really been running well for the last couple weeks....albeit with a 3200 rpm limiter haha. Also the truck I am working on is an automatic.
