installing is like 6 wires.
and you can find the ECu pinout diagrams on here and the SAFC should come with it's own diagram of what each wire is or you can download that from the web as well.
install is the easy bit.
during my tuning, Uni group put my car on the dyno, then did a power run with no changes.
took a look at the A:F details at what revs and made changes in the SAFC.
basically leaned it out or richened as required.
the SAFC I had (Blue screen) had tuning points at 500rpm intervals.
so he takes a look at the dyno run readout, and adjusts more or less fuel at each 500rpm point.
then runs it again and makes any other adjustments needed.
it took 9 power runs if i recall.
so.. without a laptop that is mapping your a:f mixture via your expensive wide band o2 sensor, while you are doing these wot runs on the road somewhere, I think it's safer to let someone do it for you on a dyno.
or if you insist on doing it yourself, you can hire out a dyno for an hour I think.
that would cost you about $110 or around that and you use their o2 sensor, dyno, computer readout etc.
