MS Trigger (to Pin 24 on DB37, or Relay Board TACH terminal) Thanks to Chris Lupkin for permission to use this drawing Distributor Wire Colors in the OEM Wiring HarnessД¬olors of the wires on the distributor side of the 4 pin round connector, versus on the harness side.

This diagram assumes you are splicing the connector from the OEM Nissan wiring вЂ“ color designations are for the Nissan wiring harness, not the MegaSquirt wiring.ДЄnd alternately, hereвЂ™s a diagram for how to wire up the relay board if you choose to use it: HereвЂ™s a diagram of how to wire it all up if youвЂ™re laying out your own wiring harness. The input side of things will be the same as mobythevanвЂ™s setupвЂ“ itвЂ™s the output side of things that will change. You will need to change the spark output pin from JS10 to D14. Note вЂ“ if using MS2/Extra, you can also build the board as shown in the MS1 example.

If you do not have a BIP373 transistor in the Q16 slot, install it.

Remove the jumper from JS10 to IGN or the center hole of Q16 (if exists).

The only change is to enable the IGBT High Current Ignition Coil Driver Circuit to directly drive the coil.

For a V3.0, connect TachSelect to OptoIn, TSEL to OptoOut.

Build the ECU up to trigger from the Hall/Optical Input (all of my MS230-C units are by default configured this way).

For a V3.57 board, this wire goes from pin 7 of the U1 socket to IGBTIN instead.

For a V3.0, use this wire/resistor combo to jumper the вЂtopвЂ™ (top as in when you facing the silkscreen side of the PCB, with the text so that you can read it normally) lead of R26 to IGBTIN on the opposite side of the PCB.

Heatshrink wrap this wire/resistor assembly.Melt the tinned wire tip to one end of the tinned 330 ohm resistor tip and let it cool.Cut a 5вЂі piece of hookup wire (22ga is fine) and strip just a 1/8вЂі or so.Tin each end of the resistor with a bit of solder.Get a 330 ohm 1/4w resistor and cut the leads down to about 1/2вЂі at each end.Cut out R57 if fitted (this wonвЂ™t be there on my units though).(Only needed when triggering from the вЂ“ terminal of the coil, which you are not) Remove D1 and jumper it, or just install a jumper wire across itвЂ™s leads.For a V3.0 board, jumper IGBTOUT to IGN to send to IGBT ignition coil driver signal out of pin 36 on the DB37.Flash ECU with MSnS-E version 024s9 or later.For a V3.57 board, put JP1 in the 2-3 position and J1 in the 1-2 position.For a V3.0 board, connect TachSelect to OptoIn, TSEL to OptoOut.Make sure it is set for Hall / optical input.If you are building your unit up from a kit you can implement these changes during assembly. This is assuming you are starting with an ECU built up like I build my assembled MS130-C MegaSquirt-I PCB3.0 units.Using the MS-I PCBv3 or V3.57 with MS1/Extra firmware

These modifications use a BIP373 ignition transistor, sold separately from the kit.

You can use an MS3 with the MS2 mods shown here, although to take full advantage of the MS3вЂ™s capabilities, it is better to use our L28ET trigger disc upgrade to allow sequential injection. ItвЂ™s choice time, MS1 with MS1/Extra firmware, MS2, or MS3. It needs slightly different mods and settings see this article for how to set it up. Note вЂ“ want to trigger a distributorless ignition or sequential injection from the stock distributor? We now offer a bolt in trigger disc that gives you that option. There is already a great write-up by вЂmobythevanвЂ™ at on how to MegaSquirt the 280zx turbo using the MegaSquirt-I PCB2.2 ECU, combined with an HEI-4 module, but what about the more recently released PCB3 ECU? Certainly you could use it the exact same way and follow the same document combining the MS with the HEI-4 module and end up with the same result, but what about that snazzy new IGBT High Current Ignition Coil Driver thatвЂ™s built into the PCBv3.0 ECU? I was recently contacted by a customer that wanted to try and go this route, and I told him IвЂ™d make the necessary modifications and document the process for others to followвЂ¦ so here we go! Level of control: Full Standalone EMSвЂ“ Fuel and Ignition Control These same modifications work for the вЂ™84-вЂ™89 300ZX, both turbo and non turbo. Directly driving the coil with the MegaSquirt-I PCB 3.0 and MSnS-E 024s9 or later or the MegaSquirt-IIДЄpplication: 1982-1983 280ZX Turbo, or conversions using the 82-83 turbo distributor
