Hey, I have a few questions regarding the MS2v3 assembly process if you don't mind answering. (for 12v VR6 / msd coilpack alternative / FI application)
I went ahead of the install manual and inserted all capacitors into the board (as per diagram) and bent the legs slightly outward so they would stay in, I also did this with the majority of resistors. I now read the steps in the manual and saw this:
I currently have all of the above inserted but not soldered into the board (C10, R10, R11) Can they all be soldered in?Note: R11 and R10 form part of the EGO input circuit (with C10). It is very important that you do NOT install a capacitor across the sensor input before R11 (C10 comes after R10 and R11 and is fine). Some people have recommended adding such a capacitor to 'smooth' the sensor input. This will cause problems, especially with wide band analog outputs such as you find on Innovate's LC-1.
Also, if you have a wideband sensor/controller, be sure to ground the controller to the same point as MegaSquirt!
Do I need to follow this step (optional) and if I do does 'installing a jumper' mean using a piece of the provided wire to connect the JS9 hole to the S12C hole?22. Now you need to make a decision on the first 'optional' component: if you are going to use an IAC stepper motor with MegaSquirt-II, you must install a jumper from the hole marked S12C to the hole marked JS9 (+12C). These are on the bottom side of the board, on the DB9 side of the processor. DO NOT INSTALL THIS JUMPER FOR NON-MegaSquirt-II APPLICATIONS - IT WILL DESTROY THE PROCESSOR!!
Do I populate the high-current ignition driver circuit or not?65. It is choice time again. In this case, you will decide whether to populate the high-current ignition driver circuit. This circuit can be used to drive a single coil in a distributor application. In conjunction with an appropriate input signal (from a VR, Hall, or optical sensor, or even points), it allows you to eliminate a separate ignition module, such as a GM HEI 7 or 8 pin module, and run the coil directly from MegaSquirt.
