Let's start the discussion about this here. I will try and summarize the following discussion by keeping this first post up-to-date editing it every once in a while. The idea: To have common wheel decoder and scheduler (CWDS) code and multiple plug-ins for various combinations of crank/cam wheels an...

BTW, since you bring up the topic of compilers and xgate, (and i hope i don't hurt anyone's feelings) but a local friend of mine, who designed many many embedded applications in past 20yrs of his career for cars and other stuff (he's one of the most known tuners in bmw world), strongly recommended m...

indeed looks like the job for XGATE

i had that crazy idea once: to try estimating PPP or do some sort of knock detection using just the wheel with lots and lots of fine teeth (i.e measuring and interpreting rotational acceleration patterns). This wheel may bring this idea closer to reality.

Thanks Sean

I've also tried to build them and gotten into few snags.

Ubuntu makes it much easier as the packages are available with apt (i used Feisty).

it's ok if it's just downpipes. It's bit more inconvenient when a hole is in the block

It's certainly a "feature" and not a basic requirement... But that said, it's something that's not very hard to do (look for crossing of 66% of the end current/voltage and multiply by 3)... Several packaged IC's find it worth doing, so it would be nice to develope. It could even go so far...

Yes, i am absolutely with you on minimizing the harmfull effects of input noise (i.e creating smart safety nets, etc perhaps even risk estimation and dealing with it statistically)

That would be all well and great, but what do you do with the 60 I/O pins on the injection/ignition/rpm/engine position CPU that aren't needed for those three functions? Waste them? I would prefer to use them, and I see no good reason not to. All things that aren't time critical just get done when ...

No problems, thats why we clarify things ;) So for the case of no vanos/vvt, i am guessing the only use of the cam wheel would be for the cylinder id. From how i see it (and please correct me if i'm wrong), one tooth is quite enough (and also accurate enough). Besides, the cyl id could be done in th...

As i was saying back in January here ... First off, i am the proponent of having all the extra (non time- and safety-critical) stuff to be on a separate CPU/MCU, to offload all the extra number crunching off the main CPU as well as remove the risk factor of the extra non-critical code somehow underm...
