IACV is not hooked up guys. It shouldn't even be running - same for the TPS activity in the logs, I don't have a TPS hooked up.
I'll definitely check the throttle cable when I get a chance.
It does this if I use the stock ignition OR custom harness, stock coils, COPs, stock fuel injector OR custom harness, RX7 550ccs, or the FIC 650ccs.

I run a NGK AFX, Brainy. For the first 20 seconds after crank, it gives invalid data because it is warming up the sensor. I keep getting tempted to throw the RX7's LC1 on the Miata, but I really don't want to tear into the RX7 right now if I can help it since the Miata is torn halfway apart, and it'd mean I have no car.
The IACV on the 1.8 doesn't work/is generally busted.

i think first off you should manually open the idle valve a bit, maybe clean the butterfly while you are at it.
no logs i looked at seemed "good" hard to tell by looking at data only, ya know?

The manual idle valve has been opened a fair bit to an extent where it idles at ~950rpm when it is warm. Should I open it even further, Brainy?
I'll clean the butterfly today, as well as order the FM 1.6->1.8 throttle bracket.

I had to max out my previous 1.6 idle valve to even get it to idle at all during warmup. The only thing the same between the 1.6 and the 1.8 build now is the MS2 and WB (Sensor has been replaced on the WB) :( - even the wiring has been replaced (Edit, at least between the MS2 and the sensors/ignition/injection/etc., obviously I didn't replace wiring on the interior for things like blinkers :P)

Well, Brainy, at this point I don't know where to go with "your junx is busted".
At the behest of various posters, I've been through two engines, several sets of sensors, I've custom wired from the MS2 harness that you made forward, I've tested/checked/tried everything that people have suggested. I've replaced everything in the car at this point that is tangibly related to it running - including being at 3 sets of injectors at this point* and an entirely new ignition system as well as running two separate coil packs from different years.
All that I haven't touched is the MS2 and MS2-specific harness, which I had sent to you about a year ago now to get working, and the WB controller.
(Edit) I've gotten most everything worked out, except then it went to all crap when I tried moving over to the XS3922's. Sure, the idle was a bit rough, startup was a bit touchy, but it all worked, then just changing over to the XS3922's made everything revert back to how it was months ago :(. I don't know if it's plug-specific, or if it revealed an underlying problem somewhere.
*: Incidentally, one of the sets of injectors worked perfectly for another poster - he didn't even need to clean them. One of the coil packs I sold also worked similarly perfectly for a poster.

Justin,
You have a PM.
Any spare parts you want to send us for testing we will be happy to check out. We have an ASNU Fuel Injector test stand here as well as a coil and ignition module tester and can scope out most of your parts. (FWIW, we are a sister company to Wells Vehicle Electronics/Airtex).
I somehow get the feeling that without putting an oscilloscope on the car with transducers to measure the running compression/scoping the valve events to rule out any valve/cam timing issues we will have to assume that there is some kind intermittent in your wiring or some EMI causing problems. I'm sure we can rule out any fat fingering in the calibration and I would guess you've checked to see if you have enough current for the COP's/Injectors.
There has to be a shop that can do the test near you for a small fee.
This is a picture of what I mean:
wiring or setup that's causing problems

Done
I leave everything 0'd out and set to 10 in MS, and then set manually as per FSM. I cannot get the idle to change wrt the timing light when I adjust it in the MS. Does this point to a potential problem?
Done
Done. Thanks Brainy.
has the trigger angle been synced? it's set to zero.
warmup enrichments need to end at 100%
turn off idle advance

Well it adjusts, lines up perfect, then when I hit burn the ignition angle is off again by the same amount yet the trigger angle has changed xxx degrees.

What firmware are you on Richy?
