All, I am installing a megasquirt system in my 81 turbo (has an 82 engine in it). When I hook up the ignition coil, do I keep the factory wires hooked up along with the the new MS wiring? I’m assuming I need to in order to keep the tachometer working. thank you for your help.

All, I am installing a megasquirt system in my 81 turbo (has an 82 engine in it). When I hook up the ignition coil, what do I do to keep the tachometer working? Connecting the factory wiring Along with the megasquirt coil wires causes problems. The spark plugs seem to fire at the wrong time. Without the factory wiring hooked up, the engine seems to run smooth. What do I need to do to get the tach working again. Thank you for any advise you can give me. -
I took the red 12v wire that previously went to the 280zx's ECU, put a 1k resistor on it, then a 2 amp fuse. That wire then fed into pin 28 on the DB37 connector as it should. When the ECU is not plugged in and the car is on, the red wire gets 12V. However, when the ECU is plugged in, I end up getting 0.06 volts (this is checked at the pin coming off the female DB37 connector on the boards bottom side). I used the stock 280zx ECU grounds for the megasquirt grounds, with one unused MS ground remaining, of which i made my own ground point to the engine block. All sensors connecting to MS are unplugged. The injectors send 12V in the pins 32 to 35, the daughtercard is out, and I took out D10 to see if anyplace after U5 was leaking the power somehow. D10 before I took it out still had only 0.06V to both ends. Voltage to C15 is also 0.06 - 0.07V on both ends, and I dont have a C30 installed. Left pin on U5 (when D10 was in) was same as D10, so no burnt trace. Even if the board was fried i figure that I would atleast get the voltage from the stock red wire.

1981 280zx NA manual trans. Currently hooking up a Megasquirt 2 v3.0 PCB to my l28e (which I just did a turbo install from NA). I have 440 cc black tops that I believe originally fit the mk I or II Supra. They are low impendence. I want to just use the PWM mode on MS2 at around 30% like the MS manual states is good. But I don't know how to wire the 6 injectors to the pins. The original 280zx ECU has pins for each individual injectors, so not sure how to handle the 4 pins allotted on MS2. Again, I don't want to get resistors or some "peak and hold module" (stated in MS2 hardware manual) if I don't have too. Do you have 3 banks of 2? For cylinder pairs (1,6), (5,2), and (3,4)? *Final note: I'm using this car as a learning experience, I understand how unethical it is to turbo a NA L28e instead of getting the L28et for dirt cheap. I picked it up for a grand and so far it has taught me a whole lot. Thank you all.

I've recently come into some money and am trying to figure which path to take as a megasquirt controller. I've read the manual and only questions several times but to no avail am having trouble trying to figure out what I want to do. For starters I have a L28e that I turbocharged from a 77 280z. The only thing I'm looking to do is controll my fuel and spark and be able to tune properly somewhere in the neighborhood of around 15-18lbs of boost. I'm just trying to figure which version my money will be best spent in and is the most user friendly. I work for CarQuest so oem parts aren't incredibly hard to come by and I have a budget of around 500$-700$ if I can get any input from current users about their systems it would be much appreciated thank you.
