MegaSquirt CEL popped on?

From my understanding it will not. I have never seen this but thought it was worth mentioning in the rare case the previous owner did this to pass emissions:

From what I have read most states that still do emissions checks on the 95 and down cars only look for the CEL to come on when the key is put in the run position and then to go out in 3-5 seconds. Would be easier to wire it to a timer than to parallel the two ECU’s.
Installing MegaSquirt in Parallel With the Stock ECU
While there are many cars where MegaSquirt can completely replace the stock ECU, on some cars you’ll need to leave the stock ECU in place. There’s several reasons why you might want to do this. On some installations, you might want to have the MegaSquirt control just the fuel and would rather...

Thank you!! I will check it today!
Well, I’m unable to find anything in tuner studios for light output or check engine light under canbus. I’m using a MegaSquirt gen2.Yes, you can enable a CEL with Tuner studio that will trigger the check engine light. It doesn't quite work like a normal check engine light.

Yep that’s the one I’m running. I’m using TunerStudio MS Ultra v3.2.05
I have that pulldown but the check engine light option is not there.SO you do not have this menu under this header at all?
Check this for Esses and Geez:
If you don't see the Check Engine Light option:
