Megasquirt 2 Hei Distributor Wiring Diagram

Megasquirt 2 Hei Distributor Wiring Diagram - These instructions are for building the V3 board for standard B&G code (for MegaSquirt-I or for MegaSquirt-II). If you are using other code, please refer to the. This provides a direct signal from the MegaSquirt ® EFI controller to the PWM idle valve. Note that the transistor on the V3 main board is NOT sufficient to drive a. The 7 Pin HEI Module. With a GM HEI 7-pin (and 8-pin modules), the ignition module wires you need to know about are: tach signal is a purple wire with a white trace [pin R] goes to Ampseal OPTOIN+ pin #30 (ground the Ampseal OPTOIN- pin #31 at the distributor) ; advance control signal is a white wire [pin E] goes to Ampseal pin #12; override (cranking) signal is a tan wire with a black trace.

Your MicroSquirt® controller can be triggered from the negative terminal of the coil, as long as your MicroSquirt® controller is not also being used to control the ignition timing.. 4L60E Modifications. If you are rebuilding a 4L60E transmission, get a good manual, either a factory service manual, or the ATSG 4L60E guide. Below is a list of the weak points in a 4L60E transmission..
