Megasquirt Gurus, I need you!

Hopefully someone with a little knowledge can give me some pointers. This is for the KL in the Celica.

The Celica ecu and electrical system is still intact. I figure I can get a speedo reading by powering the dash since I'm using the stock transmission.

I have a walbro for the tank, I've wired it up to the stock connector at the fuel sender. I should be able to run the fuel pump wire from the megasquirt to the fuel pump relay in the existing electrical system to get fuel.

The starter should be 2 wires, figure out which is positive, which is negative, and I should be set.

I just need to find a keyed 12V source, wire it to a relay, and run the megasquirt of the relay, yes?

Now I'm a bit stumped about the tach. I do have an autometer unit, but I don't know if I can create a tach signal for it from the megasquirt? I don't have a stock disty, and am doing the 6-1 "grind the crank wheel" mod tomorrow. Any advise?

I'm using the GM IAT. I found a tech article at diyautotune for how to test the resistance at different temps on the stove. I'm not sure I should be submerging my IAT sensor though?

I'll read up on warmup enrich settings. It just adds to the base map, correct? If I was careful to warm the car up before driving, I could get by with something that would allow the engine to idle cold?

I'll try req fuel as was talked about earlier on in this thread. If you have any recommendations, I'm happy to listen. This is with the lower compression pistons we were discussing years ago, on the h-beam rods. I think they are 8.5:1. Will this affect req fuel, or do I just go by injector size? (550cc).

I have no idea how to adjust spark based on coolant. I'll search for the basics. Is it special for a turbo car?

Ego settings. I thought I just had to tell megasquirt I'm using an AEM UEGO. I'll see if there's something I missed.

For some reason I thought TPS enrichment was automatic. Will read up on that too.

Help me get this thing runnin! I'm desperate to take it on vacation with me this coming week!
