If your Wideband uses a Bosch sensor, you can get away with a LC-1 control module only. A LC-1 is basically the same as a LM-1 minus the box. It has analog and digital outputs to feed either type of gauge in addition to a serial line obviously. I run an analog gauge because they are cheaper.
You should be able to rescale any of the maps for your configuration. You don't have as many tables as the STI, but should have plenty of latitude to make a closed loop and even low boost open map.
If you have the injectors mapped, mapping your intake is the next challenge to get it to hunting less or not at all at any point in open loop.
I have a spreadsheet that does double interpolation from logs to try and build the intake map based on trims and targets. It still requires some manual trimming of idle and off throttle data, but works for me.
