Haltech injector staging primary hold mode
I am running into a glitch, not sure what the cause is but I'm hitting fuel cut unexpectedly with some randomness.
First off the cause is not overboost cut, antilag, the 2step or any of the other features that I can think of all of those are verified as being off.
It can be seen clearly in data logs, after 4300 rpm the injection times (primary and secondary) go to zero for both injectors, and bounce in and out of zero.
Weird thing is it doesn't always happen.
I am using the current haltech beta, possibly a bug???
I think it could be related too the injector staging mode, thats why I'm mentioning it here...
log excerpt:
PRI is logged primary injection time, sec is secondary injection time, notice the zero's in the injection times for both. 10 seconds later It didn't happen....

This has got to be a halwin bug...
I see a possible cause, even though the settings are grayed out (turned off in halwin) both the 2 stage rev limiter and antilag where set to 4500 rpm. I'm thinking from the looks of things that it was trying to do a fuel cut rev limit.
have you ever known the e8/e11 series to try and use features that where turned off???
The weird thing is that ten seconds later through the same load and TPS areas it didn't happen.

I activated antilag and the 2 step limiter and set them beyond the RPM range that I use (like 10K+) then turned them back off. Problem went away.
At this point this is almost certainly a halwin 1.82 bug. Again both features where grayed out, and NOT activated.
Why anyone would want to use fuel cut as antilag is beyond me...
