sorry if im hijacking but maybe another alternative just discovered an interesting thing the adaptronic ecu now has an option to supply a plug in loom for the r33 rb25det
New Products: Plug in looms and Igniters
Adaptronic have designed and built a plug in loom for the R33 skyline(RB25DET) which may also suit other R33's and R32's, and a plug in loom for the Suzuki Swift GTi G13B Mk2 & Mk3, we are still interested to hear what other vehicles you would like plug in looms for. We are now also stocking single channel 'dumb' igniters for those of you who decide or need to change the ignition system
http://www.adaptronic.com.au/ $990 for ecu and $350 with loom and mapsensor
so $1340 all up and u can use a laptop to tune and monitor
maybe the new upcoming ecu for all *ponders the thought*
