Yeah, somebody here was a bit lazy about that draft diagram.
Unfortunately, although I've done TFI setups before, I didn't have one on-hand to do field-test confirmations when I made that outline for Speeduino. It was all from memory and conversion to Speeduino terms. I was waiting for the inevitable minor correction or simplification feedbacks for a final version that never came, but it appears to have been sufficient for others that have used it real-world. Typically, when things go well, people go quiet as they move-on. If you'll provide the feedback to each part of it, we can finalize and remove that watermark.
For example, expanding the short note of setting base distributor timing (e.g., 10°), with a simple procedure for setting Trigger Angle
to get controlled timing accuracy. The issue is if setting TA at 10°, you may be reading auto-triggering by the module, instead of commanded timing from Speeduino. Not a big deal (set TA at 15° instead), but something the diagram outline should include with a simple and proven procedure for first-time success.
Once set-up and running well — I'd appreciate testing to confirm a shift to 0° base timing, with removal of the START power wire, allowing true 0+ timing. As it is, base timing is the minimum timing available, but the shift would allow reduced advance for those that wish to optionally use stuff like that. While this would defeat the self-triggered cranking-timing benefit
, it would allow features such as Idle Spark Control
to provide retarded timing for idle speed management.
