Nexia with 'RED TOP' C20XE
So ...
I need to help with my current config.
Engine "cutt-off" on drag race, when I'm shift up, and I can't see why..
(tps 100 to 0 to 100)
Can anybody help me explain why..??
RPM, VE, TPS and other things looks good in log.
(due to "over-fuel" .. or why ..?)
Drag race start at aprox. 260sec
Thanks.

Re: Nexia with 'RED TOP' C20XE
It looks like when you lift, the fuel cuts off and then comes back on for one quick blip and then it's off for good.
This is just a wild guess, but it may have to do with fuel cutoff. Maybe you exposed a glitch, or maybe your settings are screwy. Your rpm settings with 2500rpm and 2300rpm don't seem to make much sense anyway. I would turn off the fuel cut-off and see if that helps.

Re: Nexia with 'RED TOP' C20XE
You're hitting fuel cut because it would be over 100% duty cycle.
Notice how the "fuel: base" channel is up at ~38ms, when there are only 28.5ms worth of time to inject at the current engine speed.
Now: why are we trying to add all that extra fuel? I think something is going wrong with engine load acceleration enrichment. All your sensors look OK, so I don't see where that extra fuel is coming from other than engine load accel enrichment.
It may be worth disabling engine load accel, and relying on exclusively wall wetting enrichment. It seems for lots of engines using tau = 0.3, beta = 0.3 is a reasonable starting point. Beta controls how much correction happens immediately after a change, and tau controls how long that adjustment lasts for.

Re: Nexia with 'RED TOP' C20XE
OK ...
So, now I see 3 vriants of enrichment.
TPS , Wall wetting and Engine Load.
Now I need to do, is try to use one of them .. (RIGHT .. ?)
Set all to zero in Engine load, then Engine Load Acceleration Tapper Graph will be ignored - at all
Try to disable TPS enrichment, same way..
(tps map have number 37 )
..and then try to run ...
My engine have ITB, just for record.

Something like this will disable everything other than wall wetting enrichment.

Re: Nexia with 'RED TOP' C20XE
Thanks, I will test it ..
..and when I can use TPS accel ..??
Maybe will be better, if anybody write documentation .. on wiki page ..

Re: Nexia with 'RED TOP' C20XE
I found these pages sometime before.
It looks little bit outdated.
and some description for "numbers" Length Cycles, Accel Threshold will be helpful.
I have no idea, if it must be 0.55 or 1.74 or 34.578 ...
(need some hint for these settings)

Re: Nexia with 'RED TOP' C20XE
Thanks.
I will try some settings this weekend, from other configs.
(Online "archive" )
Maybe one wish or hint for accel enrichment strategy ...
about MAX fuel value ...
As mck1117 described me, I have fuel cut due to max duty cycle ...
required 38ms from TPS>TPS table, but max available inj. time is 28ms.
Is able "cut" or "shrink" maximal accel enrichment time to current max. available injection time ( duty cycle 100% ) . ..??
or ...
is possible have inj. duty cycle over 100% when accel enrichment occur / run ..??
WITH NO FUEL CUT
(it is my idea at this moment and if it is not possible, please ignore it )

Re: Nexia with 'RED TOP' C20XE
That's a pretty good idea - I'm already working on improving this part of the firmware, so I'll add that to my list of things to consider. Thanks!JRD McLAREN wrote: ↑Fri Aug 07, 2020 7:55 pmMaybe one wish or hint for accel enrichment strategy ...

Re: Nexia with 'RED TOP' C20XE
Guys ...
I need help with FSIO formula for power steering pump.
Conditions are:
Vbatt > 13V
RPM > 700
VSS < 60kmh
I have set output #1 - 14 GP Out 5 (used as 12V High-side)
and now I'm totally lost ..
I need to "wrote something" into "Setting"
- set#1 700
- set#2 13
- set#3 60
and then "FSIO Formulas" will be:
rpm 1 fsio_setting >
vbatt 2 fsio_setting >
vss 3 fsio_setting <
.......... ?
or it can be set via console:
set_fsio_expression 1 "rpm > 700" and "vbatt > 13" and "vss <60"
