Not getting any response on the shop talk forum....project is a blown Type 1 motor. It's a stroker 92/82 displacing 2180ccm and it has the Hideaway turbo kit from CB Performance with a HEI ignition. We put on a Megasquirt-II instead of the Delco ECU to get more tunability. Now I am looking for some pointers for the ignition table. Here is what I came up with so far. Please give me some feedback.

I'd consider running a lot less timing, like 36 degrees as the max. Keith Duckworth used to be very pleased when any engine could run at peak performance with less than 25 degrees of timing. Engines with pretty crappy combustion chambers often need 10 degrees more than that. Any more, and you're most likely working against yourself. It will probably even run cooler. However, I know nearly nothing about Type Is, and absolutely nothing about turbo Type Is.
Those big jumps, like running 20 degrees at 1000rpm and 27 at 1300, at 90kPa, seem odd to me. |
