DIM Electronic Advance Ignition

Dan,

Thank you for the comments. I use a less that $300, 10.1" minibook with USB port. I have a special application that I wrote for development. It is all in one, for updating code, presenting real-time data with meters and charts, setup and table changes, and data logging. I have other ideas to use what most people carry with them every day. That is another project.

The RPM is measured by measuring the period of ignition trigger signals. The reciprocal of period is frequency, scale to revolutions per minute you have RPM.

Bill,

I will pick up an e-core coil and do some evaluation.

I have always developed synchronous fuel injection based on speed density. I measure fuel requirements for each combustion event. Cylinder filling requirements are determined from manifold pressure, temperatures, VE table, RPM and TPS, with WBO2 for feedback. I found that sequential control reduces low RPM emissions and improves idle quality.
