you HAVE to have a datalogger. Without it you are just guessing.
Some people might get thier guesses pretty close but guesses they will still be.
If you have a datalogger, here are some good links to tuning with it.
http://members.rogers.com/mrjackson9/FAQs/SAFC_Tuning.htmhttp://www.vfaq.com/TMO/ Used to have another by Kyle Tarry, but its a big 404 now.
Here is another SAFC install page too. Just for fun
http://www.plymouthlaser.com/safc.htmI have installed mine and other electronic things like 2g maf in a 1g. I find it helps to take a sheet of paper and write out on it what colour each wire that is attached to the component(SAFC, MAF etc) is and where it goes to on the cars wiring harness.
EG: green/red tracer on the Domahickey goes to the brown/white stripe on the harness. (example only, not the real connection)
Put a line down the middle of the page and organize the wires this way. Object on one side and harness on the other.
also remember to solder, not butt connectors, not twist it up. Make GOOD joints, and with that ground, and the brown and black, the order IS important.
Also, remember that an SAFC and the ECU run on smoke.
