Go with a megasquirt.. you will get better performance and the price is about the same.

Just do a search on the V6 section. This is a very commonly asked question.

KL-31 (Usually from Efini MS8 with Manual 5-Speed Transmission)
(Only works on manual transmission wire harness)

KL-36 (Found on Automatic Transmission J-Spec vehicles Efini MS8, Xedos9, etc.)
(Will work with both Automatic and Manual Transmission)
If used in the Manual, one connection is not used on the ECU, and the VRIS RPM points are just slightly different but it shouldn't really be noticable.

It's important that you pair these ECUs with the right VAF/Intake Manifold combination. Best for fuel efficiency and power in my opinion would be:

ECU: KL-31
Intake Manifold: Millenia/Xedos9 (Curved Neck with Square Runners)
VAF: Stock MX-3 Vane Air Flow Sensor JE-50
