Hello:
My first post here. Which is the recommended Dwell Time for the following GM type Ignition Coil ?
Specs
Primary .2-.7 ohms (.45 ohms)
Secondary 6K-11K ohms
Inductance near 2.8 mH

Does the M400 adjust the Dwell time automatically based on engine operating conditions?
Thanks in advance.

It does not look like we have the exact dwell curve for that coil (we really need part numbers, etc.) so it would be best to have it tested to make sure you have it set up right in the ECU.

The Dwell settings in the ECU are in the form of a 3D table. Generally the table is only 2D based on battery voltage.

Hello Mark:
Thanks for your reply. I will like to send one coil for testing. Please, let me know how I can do it. Thanks.
