E-Manage Ultimate rev limiter cut

[j.oe]

Througout a whole afternoon we tried to get the rev limiter cut work on my j-spec tt to rise the rev limit to 8k. Whatever we changed the values for wait time, factory rev limit (6500 to 7000), always the stock rev limit occurs between 6950 and 7100.

Injector durations in the table are properly set to what we had logged at the rpm level before the stock rev cut occurs.

 

Has anyone here an idea how to proceed to get this work ?

 

Thanks

Jürgen

I got mine to go from 6800 to 7200 with the attached settings

 

 

(and yes, my durations for 1.6bar are impossible, but I only run 1.4bar tops so it really means 'uh oh, overboost, maximum fuel please')

Thanks mate

 

Am i right on the assumption that your inj. values are in milliseconds ? If so, then 17,7 @ 7200 rpm means more than 100% cycle and is used to shut an overboosting engine down by fuel

Do you have any experience wether there's a difference in changing the scale to milliseconds or percent inj. cycle that generally makes it work or not (correct and sensible values provided)

? I ask because we used the %cycle scale and typed in the values we logged right before the rev limit cut occured.
