Self-Tuning Fuel Injection

[davepl]

Does anyone have experience with any (or ideally, more than one so you can compare) of the self-learning fuel injection systems?

I'm trying to get a feel for how "good" their learning is for a few things, such as:

- Just getting the base map (VE) table right for each load v RPM cell
- Getting tip-in enrichment (like an accelerator pump) right
- Timing

It'd be pretty easy to do the first bullet point. The second one is harder, the computer would have to try various amount of enrichment and look for a bog to occur a little -later-, which makes it harder code to write.

Without a knock sensor I presume no timing "self-learning" is possible, correct? Do any of them actually do it with a knock sensor?

Thanks!
