On my short list of upgrades to get for my VR4 is ECMlink rather than the generic chip I have. I want to use wideband o2 and EGT for tuning, and wanted to check I can do it the way I think I can from reading the wiki. Can I use the EGR input for EGT and after observing what the stock o2 sensor outputs, use it's input for a wideband o2, and use the stock o2 simulator function? If I can it means I don't have to buy seperate gauges/loggers, which would mean more money and hassle getting all of the tuning data together.

There is no input on the VR4 that's directly compatible with an EGT sensor. I know there are some gauge packages (like ApexELEGT) that provide a 5v EGT output, but unless you have that, there's no way to datalog an EGT sensor directly with the VR4 ECU.
That said, once you have a wideband wired up, I'm not sure an EGT will provide all that much more data.
Your other thoughts / plans are correct on the wideband.

OK, so if I skip the EGT can I use EGR in for an LC-2 WB and leave the stock o2 alone? Thanks.

Egr is a output.
Put your wbo2 in the dump and log it in ecmlink and simulate nb. Wire it to front o2.
If you want a gauge to look at in the car, get a innovate mtx-l its cheaper than a lc2 and gauge.
