There are three important numbers to change, and one more maybe need to change that I can think of. You need to look at the cal you're running and find the reference angle (should be about 60 degrees) the max advance (should be a negative number) and the max retard (should also be a negative number). Copy each one into the $59 calibration you want to try. If your engine uses the 1X ignition wire you can disconnect or disable it. Don't use the V6 numbers. They may be close but you're better off with the right values.

EagleMark was working on putting DIS on a Toyota at one point. There is a huge thread with a ton of info, but it goes back and forth and may be confusing. This post does have Q4 wiring diagrams: http://www.gearhead-efi.com/Fuel-Inj...ll=1#post31488
