Default '90 w/ MSM swap first run/troubleshooting

It lives!

Setup:
1990 chassis
'05 MSM motor, stock turbo, piping, FMIC, downpipe, TPS, CLT, injectors
GM IAT in stock TB inlet
Forge recirc replaced the OEM plastic unit
1.6 coil + CAS
Brand new MS2E from Reverant
Innovate LC-2

Initially:
No start. Ignition switched from 99-00 style to CAS (4G63). Oops. Communication error resulted in this one.
Second try. Starts right up. Rich, rich, rich @ 10:1, idles fine enough though, sensors read out about what I'd expect. Warms up, gets a bit hot, fans kick on. Burp some coolant, temp comes down, all good.
Still reeks of fuel, cold and hot.
Re-ran initial timing/TPS calibrations for *****.

Troubleshooting/observations:
Open air recal of LC-2
Standard vacuum leak checks
Disabled knock sensing since sensor isn't wired up
Tried various nipples on IM for MAF/FPR source, with no change. Reverted to what I thought was "known good".
Ambient temp was ~55-60, IAT seemed about 10 under this. Used heat gun w/ sensor pulled to verify increased temp reading in TS. Seems normal. Let it cool off to where it matched ambient, reinstall, start car, no change.
Car seems to idle fine, but it reeks, and the LC-2 matches my sniffer. None of the above steps changed a thing.

I'm attaching an MSQ and Log for your perusal. Your insight is appreciated. Thanks!

Grew a pair, took some fuel out and got expected results.

At least I can leave it idle to check for leaks now. Dat smell was killin' me.
