As a last test, I pulled the O2 wire out of the connector and hooked up a voltmeter to it. Prior to starting the engine, it read about 5V. After I started the engine, it read around 2.5V (some bouncing around between 2.4 and 2.6 really). It looks like the Megasquirt isn't working then. I'm actually ...

Well I'm still having O2 sensor issues. Went to start the engine, and found that the reading was 7.4:1 again. Re-flashed, and it went back to 17.0:1 (but strangely not 18:1 as it had previously been doing). Had to turn it off to put a fuse back in (not related to MS), and turned it back on to see 12 ...

Thanks Matt, when I looked at the Logworks display it says ~20:1, but this is in the exhaust pipe also so it's probably different. I've been digging further into the issue, and took the board out to verify 5V on the processor pin (which was there). Then I decided to reflash the FW on the Megasquirt ...

Yes, I calibrated the AFR map using the LC-1 default settings option. I also thought that free air would be a high reading, but less than 5V since free air isn't 22:1 but closer to 20:1. Using Logworks, I see a reading of 20:1. I'm thinking about using a AA battery or something to connect to the MS ...

So it looks like the EGO ground should be on the engine, not the sensor return, is that correct? That's how I have mine connected. I'm using an LC-1, and I can't seem to get any reading on the TunerStudio other than 7.40AFR. I've set up the project properties for the LC-1 as well as calibrated the ...

OK, I found that it works much better when I put a fuse in the fuel injector fuse holder. Before that, though, I spent more time with the timing light and found my crank offset was about 20 degrees too advanced. It was probably good to figure that out before injecting fuel. After putting a fuse in ...

I've got a sequencer, and am not getting any sort of starting success, not even a cough. I tried some starting fluid, and after some cranking got a cough and a backfire out of the throttle body. An inductive timing light flashes as I crank, it's really hard to see the timing numbers while cranking ...

Haven't heard anything about the sequencer for quite a while. I've been hoping that it would be available soon, but am now considering getting a Powerjection III or something just to get rid of my carb that I can't seem to get right. Is the sequencer pretty close, or still months away?

Will the sequencer be able to control a stepper IAC, or is it the same as the Microsquirt?
