Some analysis please

[JasonNA]

Car is a 1991 MK1 1.6 MX5/Miata with:
- T28 turbo conversion
- MSPNP gen1
- 550cc injectors
- Innovate LC-1 wideband
- Magnecor 8.5mm HT leads
- NGK BKR7EIX Iridium spark plugs

I just swapped in a replacement engine and it seems to be running very rich, the smell alone would give it away.

Attached is the datalog and the MSQ that is on the Megaquirt at the minute, this was tuned professionally and not by me.

Can anyone please have a look at what's going on as I'm very much a beginner when it comes to engine management.

First try giving the LC-1 a free air calibration. The readings are bouncing hard from 0 to 5 volts, and that sounds like the wideband may not be getting a proper reading. If it's not reading correctly, that will make it harder for me to interpret the data log.
