Help with map, trigger issues

Can any of you guys give some input on why this is happening? See below:
I see that "FALSE SEC TRIGGER, FILTERED" and my car's idle just surges, doesn't stay constant. Been working with Scott at ATS Racing, but figured a post here can't hurt.
This is a 93 MR2, Gen2 3SGTE with pretty heavy mods. I can post my map and logs if need be. TIA!

Why don't you try to disable camsynk above 600 rpm?
The camsynk is located in the distributor right?

It is for this car, yes. Currently, now that I am looking at the settings...the camsync cut off is 15,000 RPM. So, I am gonna change that real quick and see what happens.

Do that, it will help. Or try change sensivity switch to 600 rpm.

It worked! That error is now gone from the log! Now I only have to deal with that surging idle, I don't know much about getting that down so I can at least drive it

Go in under idle ------ idle ref table ------ increase the whole row

Tried increasing, a few times. Still surging between 1900-2100.

Played around with it some more this morning, still no luck. It revs straight to 2k and stays there for a good 3 seconds, then starts to surge. I haven't broken-in my motor yet, I hope this isn't hurting it

Hows your afr and ignition angle? Sounds like a tuning issue

To be honest it hasn't ran long enough for AFR's to read on my external Wideband gauge. I hooked up the Analog output from the EMU to my WB output, although the voltages bounce around, as seen in the original post. I am running full e85. Ignition Angle is 0...guess my base map doesn't touch that.
I am waiting to get tuned, but there is a wait time...I am just trying to get the car to move under it's own power before I have the tuner try and fix any issues I have.

It's just hitting fuel cut. Idle needs to be set with throttle body, then adjust TPS.

Posting this since I fixed the problem:
IACV was letting in too much air, even after adjusting the throttle body.
Solution - plugged the IACV, car idles at 1100 now.
