The MAP is not unplugged. I've also blown and sucked on the vacuum hose to the MAP while running the software and it increases or decreases depending whether blowing or sucking. I don't know what to say about the RPM signal. It is a brand new MSD ignition box that has a square wave output. Again the ...

Does anyone have any suggestions? I've double checked the ignition system and confirmed it with spark. I've sprayed fuel (using a squirt bottle) in through the throttle body and the car tries to start. And the spark plugs have been dry when I pulled them and checked immediately after an attempt. So ...

Here they are.

As suggested, I installed the base tune and went through those settings as outlined in the manual. The engine won't start. The engine was run on an engine dyno with a carb. We did the break in and set the timing at this time. I've checked and the engine has spark and I can smell fuel, so I know it ...

I'm looking for a tune as a starting point. I know each engine has it's own quirks and no one tune is the same even if the engines are "the same". I'm looking for either someone here to share their tune, or a place to browse and download a tune.

The specifics: MS1 v2.2 (fuel only)
Engine: sbc 383 ...

I didn't. I bought it already assembled (not from DIY). Problem solved, I ordered a new one fully assembled from DIY.

Do you have any idea why this would be the case?

Should the fuel pump and 12v+ distribution bar (used for injector 12v supply) have power to them when the switched 12v supply is OFF?

I've connected 12v supply from the battery, 12v from switch, and main ground to the relay board. While using a tester and the switch in the off position, there is ...

I'm 90% sure I found the problem. The copper band in the relay board from the switched 12v connection to the main power relay socket appeared to be burnt and making a partial connection. Now the question is, can I solder the copper back together, or should I solder in a new wire on the other side of ...

Thanks Ken for the response.

Yes the injectors are controlled by grounding. On the relay board there is a 12v supply for the injectors (red line on attached picture). This is where I'm testing and only getting 3.3 volts from the relay board to the injectors. I can't return it to the original ...

Who would be recommended to send my MS to for diagnosis and repair? I've sent emails to peter at first fives as suggested in the manual, but I get no response.

I have a MS1 with v2.2 board and the DIY relay board. I have 12v from the battery, 12v from switch source, and solid ground. I'm only ...

I have a MS1 v2.2 with a stim v2.1. Before installing the MS in the car I plan on using it in, I wanted to test everything. I just downloaded TS lite, purchased the tuning cable and DB9 USB adaptor from DIY Autotune. I've plugged everything in using a brand new 9v battery, created a new project, and ...

As the subject says, I'm new to this forum and MegaSquirt. A friend bought a MS1 v2.2 for a project back in 2004 and assembled it in 2006 according to his notes. His project never went anywhere and died as they sometimes do. I bought everything he had from him for a project that I have a couple of ...
