Ignore this post. I added the jumper across D8 and everything has lined out. Running great. Going to finish tuning with tuner studio tomorrow.

MS - 1 Datsun 280ZX 6 cylinder


I have been successful starting the engine. Sometimes when I start the car it runs fine at around 1200 rpm. Smooth with no issues. More often that not I get a fluctuating RPM between 400 and 500 RPM. If I pull injector number one's lead the engine dies.

I have a ...

I now have everything hooked up correctly so I am seeing good data. The tach signal is either spiking or dropping out while the car is turning over. I currently have both diodes in the tach signal circuit jumpered. Should I take the jumpers off and see what happens? I also am seeing inrichment ...

The code version says "MSv30BG" i think, this is on the cpu

I have attached new pictures for you to review.

I have tried the unit in the car but lose my injector firing a couple seconds after cranking starts. Is the fuel pump signal required for the Ms to keep the injectors firing or do they shut ...

Will do, I have to find a camera that meets the requirements of this website. What I have shoots to large a shot.

lance, I have checked for bridges and any cold solder joints. None.
I cleanded any excess flux off the board and it looks clean.

From pin #24 to C12 the resistance to the top(furthest point from (www.grippo....) is 382 ohm, to the bottom(closest to (www.grippo....) 7.72K ohms.

ground pin to c12 is ...

Thanks Lance, I am building the V2 version 2.2 and I am using going to use a negative signal from my coil. The instructions tell you to use C12 and jumpers from XG1 to XG2, and both the D5 and D8 need to be jumped for the Stim to work. All of those are in place.

Once interesting thing. I made the ...

I am putting together a MSII. I have the unit completed but have no tach signal. I was following the voltage through the tach chanel and got to C12. When checking c12 with a volt meter I get an open line. By accident I had the Stim attached and running while checking the resistence across c12. The ...
