Woo Hoooo!

Thanks for adding me to your friends list! I'm THRILLED!!

Got myself an MPGuino (not installed yet, will be this weekend).
I wanted to dabble in the MPGUino sw dev. Can you give me some simple steps to set up environment for it? I use Kubuntu Jaunty, 64-bit AMD, and I don't see any instructions for env setup for this OS.

re: vss list, I think we are about there, I am going with the doubled values after seeing the single value mode flake out in a metro, and we need to add in the constant "mechanical delay" too if/when we have the double pulse sorted out and then look at the fuel parameter. But we are close.

re: piezo, those are amazing and cheap little things. I use 'em as part of diy midi drum pads too. I should give that a shot

I think its time to start a thread for users to post their settings as far as VSS and injector flow rates based on year and model cars.

Great work so far. Thanks for all your time.

dcb,
if you get a chance with a scope, this just might work to test an injector. chan 1 & trigger hooked to injector voltage.
channel 2 connected to a 'knock' sensor or piezo-mic glued on top of the injector. (accelerometer)
what you should see is an acceleration when the injector pin starts to move and then when it hits wide open a larger acceleration spike.
Upon closing the largest spike will probably be when the pin snaps shut. Don't be surprised if the pin bounces a couple of times when it hits the end stops. John
