I'm only up to the 9th/10th map though, so I can still tailor them to the WI.
I like the idea of adding TPS. I'll do some logging, and see if I should add it.
I'm only pulling about 126 (raw air volume) on the stutterbox. I'm going to try turning the WI on ~144 and see how it works.
Now, I'll have all kinds of time to talk about DSMs, because I won't be busy fixing mine!

I think that triggering off of boost would be more consistent. In my logs I've found conditions where I would be in the highest fuel/timing map at different boost levels.
I have my WI triggering on in the following coditions:
TPS>75%
RPM>3000
Boost>2bar(~15psi)
Still tuning it though. You could also toss is a check for if the car is moving, that would disable the WI if you're using the studderbox.
Later, Vlad. Nice, I am guessing that DSMlink can trigger the WI on for the functions above, or are you using something else?

I'm using the speed density chip created by pudhed from the dsm-ecu group with some slight modifications.
I'm triggering the WI with a negative pulse to the relay from the purge solinoid on the firewall.
The only thing I have to work out is that there's a momentary trigger of my pump when the key is turned to ON. I'm guessing the ECU is running solinoid checks when the key is turned to the ON position, I'm sure that this can be eliminated if I looked into the disassembly a bit more.
When I first started using WI I was using a pressure switch to trigger my WI, I find controlling it via the ECU gives us more flexibility.
Later, Vlad.
