Nope, overboost won't work either. I found the problem...
I'll post the fix once I figure out how to fix it.
Here's a new .asm to try. Let e know if it works and I'll put it on post #1.
EDIT: removed, wasn't right...

Ill try it out when I get a chance, The van is still parked from it cutting out on me the other day. Im going to re do that ground (again) and throw a coil at it and see if it does it again. Thanks for looking at the code though.

Working:
Rev limiter works in gear at speed. I set to 6k and it's spot on.
Not working:
Launch control limiter doesn't work. I tried 2 different set methods, speed control set and speed control on/off and I did try after I had been moving then came to a stop and tried.
Not tested:
Overboost. Wasn't able to hit overboost as the first time I tried with the stock T2WGDC curve it wouldn't boost past about 12ish.
I did not test free rev RPM limiter...don't like to free rev that high.
Logging results are odd for WGDCC.
MPScan never showed it at 100% even though it should be 100% at 0.0psi to 5.3psi.
For example:
Boost = 5.0 psi
WGDCC = 30%
RPM = 3875
TPS = 3.6v
Temp = 186°
I was able to get the boost up to 15 psi, but I had to lay out the FullThrottleWastegateDutyCycle quite a bit. For example my current cal has 40% duty cycle at 13psi.
This is where my lunch hour ran out...sorry.
Fyi: Rob, I'm using the newest asm and Johnny Lo tpl file with some tweaks for the AIS
I'll see if I can get some tweaks in before I leave to lower the overboost to check tonight on the way home.
Let me know if there is any specific sequence of events/actions you want me to test.
Does it have a switch condition enabled? I think by default, I have it set to look for the brake switch. You might have to turn that off (IE, no switch).Not working:
Launch control limiter doesn't work. I tried 2 different set methods, speed control set and speed control on/off and I did try after I had been moving then came to a stop and tried.
where do you access the wastegate curve? Would this be something to mess with or is it something to leave alone?
I had "launch control" checked under CalCustomConfigOptions2 and
I tried 2 different settings under "StagingLimiterEnableSwitch"
BUT, I missed "bang bang" under options2. I'll enable that and report back, or does that matter?
oh, what is StageLimiterMinTPS? is it tps voltage has to be below this when enabling the staging limiter? I know the description is "fuel added while launch control is active" but that doesn't make sense to me as ( doesn't seem to correlate with the parameter name )

StageLimiterMinTPS is the tps voltage that enables the staging limiter. I have success using the cruise resume switch to enable the staging limiter. I don't see enough tps or rpm to activate the limiter when setting the cruise and it makes a convenient switch to use anytime.

So the voltage has to be above or below StageLimiterMinTPS?
I initially interpreted StageLimiterMinTPS like this:
The TPS volts has to be lower than this to be allowed to enable... do I have that right or does the voltage have to be lower than that setting to allow the staging limiter to be set?
That may be my problem, the delivered setting is something like .765 but my TPSv is like .862 when closed so I set it to .980
... my brain is sooo cooked from looking at this stuff
The StageLimMinTPS is a threshold for the stage limiter to activate. It's TPS over MinThr (MinThr is measured as the TPS volts at closed throttle). In your case, the total TPS required to trigger the 2-step would 0.86+.76 --> maybe too high.So the voltage has to be above or below StageLimiterMinTPS?

I set this so that you could, theoretically, rev past the staging limiter with low throttle opening. For cars that are set with a low rpm 2-step, and no switch to turn it on/off (IE, speed only; usually manual trans cars), it helps to have this so that you can roll away from normal stop without triggering the 2-step.
If you don't want to use this feature, just set it very low (~0.1v should effectivly disable it). I've found that the 0.7v I set it to initially is too high. I use 0.5v in my car now.
Also, I found the error that fixed the main rev limiter, but killed the staging limiter/launch control/2-step.
But, I fixed on the airplane last night. As soon as I can get my notebook to sync with my DropBox, I'll upload the new .asm for testing.

Doesn't matter. The difference is just between the 'smooth' style and the traditional anti-lag 'bang-bang' style rev limiter. I prefer the smooth kind for drag racing - I'm trying to hold a specific RPM more than build boost.
It's under boost control, wastegate settings, FullThrottleWGDC. If you're tuning your boost control, this is the main table you want to adjust...
I need to buy a flashable smec..this removing to program thing is for the birds
New .asm to try...
I dunno about this last version, but so far the staging limiter has worked great for me, I have it set to activate at over 1.00v on the TPS and disables above 5mph.
In the last release, the staging limiter broke the main rev limiter, and over boost, the speed limiter, etc.
I posted a test .ask on a previous page that fixed that, but then broke the staging limiter.
The version above should get both working right.
okay cool, I'll try it out tonight.
Both limiters work for me
