I have been reading messages on this forum and though I would let you know what I have been using.
I purchased a ecu package that includes eprom reader/writer, daughter board, and software and documents.
I now have 390KW @ wheels on my sr20det powered 180sx.
The kits are really good value for money costing $150US and included the eproms with 4 maps pre programmed, which I can switch while I am driving.

It works out alot cheaper than the jwt ecu I was using and I am getting more power just from programming it, the standard maps gave me a better power curve.
