MPGuino release one workspace

[orange4boy]

I'm a weiro/geek/person/thingy and use a Mac...how much of a pain would it be to use my Mac for setting a MPGuino up?

I'm using a Mac and Arduino works fine. I had one little problem in that the sketch was to big when loaded with my Mac so I had to trim some lines. I have no idea whether my sketch is stable now but Arduino pointed out an error when I first did it, I cut that line out too and it seems to work. I'm hoping dcb will check out my code to see if it's o.k. He seemed to think that the different platforms might change the code. It's only 10K over so there's not much to cut.

10K over, "not much"? The whole thing is 14K!

Sorry,

Binary sketch size: 14346 bytes (of a 14336 byte maximum)

Shows what I know about programming.

I'm actually rolling with 10.5.5 =)

I'm just gonna go for it, but money's tight right now i so i don't want to just go and blow Xnumber of dollars and not be able to do anything with it.

I assume your tercel is fuel injected, not sure if you have a speed sensor on that car or not. You could possibly add one if not, but I don't know if anyone has done that yet.

If you dont have speed/distance, still if you have a regular commute it can be useful to keep track of how much fuel it takes to get to work and back and try and beat yesterdays score.

Ah, you're over by 10 bytes. 10K would be 10,240 bytes.

You are officially forgiven.

The Tercel should have a speed sensor, as long as it's the 3E-E (fuel injected) engine. If you need help finding it, let me know, I can take some pictures of where it is.

And yes, even if you can't find it, it's still useful just to see how many gallons/hour you're using. My speed sensor connection wasn't hooked up for a few days, and you can still get a pretty good sense of how much gas you're wasting just with the injector signal hooked up.

I got my iDuino soldered together on the first try--my first soldering project. (Well, it passes the Blink test anyway..) However, after agonizing over how I was going to breadboard the rest of it and where I was going to order the other parts, I came across the lovely MPGuino kit. Methinks I'll be ordering that and using the iDuino for other projects.

Does the arduino have an input that could be set (on/off) when a bank is shut off so that the increase in the recorded injection duty cycle could be cut in half, or whatever fraction is required, in order to display the correct mileage?

[dcb]

do you mean like a cylinder deactivation scheme? (not easily)

or like in one of those setups that do some injectors simultaneously when cold but sequentially when warm? (it should already work regardless)
