I know this is a pretty old post but wanted to share a finding of mine relating to "02 surge". I recently installed a wideband 02 sensor on my engine which I also recently converted from a 2 barrel TBI to a 4 barrel TBI. Not very long after installing the new wideband sensor I turned on EGO Control ...

Just wondering if anyone ever replied to this as I am kind of wondering the same thing. I've read over, over, over and over the Automatic Mixture control page and at least for me the descriptions of what each setting does seems a little to vague for me to understand just exactly what each setting ...

Would there be a way to build the v3.0 board so that a separate pin on the DB37 supplies power to the RAM only?

That way you could put constant battery power on that pin and set AMC to RAM Update only and not lose your new fuel table in ram when you turn the engine off. Then if the table gets ...

Forgive me if this has already been addressed but I searched all over for an answer, couldn't find a direct one in the forum and the manual doesn't specify. On an MS2 Does the IAC control idle to get the engine back up to idle speed under load such as when an A/C compressor is turned on or clutch is ...

Notice in the log how the cranking pulse width is about 5ms. In the MSQ my pulse width at 160 is set to 3.3. Why would the ECU send out about 2ms longer of a pulse?

I think I figured it out. It appears that ASE is automatically disabled when WUE is off with the MS1. With MS2 you can enable or disable ASE on hot start. It would appear that ASE is reliant on WUE to be on so if you enable ASE on hot start the ECU must turn WUE on in order to turn ASE on. Sound ...

I think I can probably get the starting response figured out by comparing my old logs to the new ones but the thing that I'd really like to know is why the WUE would trigger on hot start and if it would even effect anything above 160 since WUE is set to 100% at (and above) 160?

See attached log. Thank you!

I'm running fuel only. code v2.92. Here's an msq. The log is too big to attach. Is there a way to delete some of the log?

I've been searching the forum for an answer to an issue that myself and this person was having but it didn't look like my issue was answered in this thread. I recently upgraded to the MS2 chip (great processor by the way, very smooth and doesn't show any of the spikes on the log that the MS1 did ...
