Unichip

Has anyone run a Unichip on a '98 LS400 VVTi ?

I'm running one in my '99 SC400 VVTi.
I have it running and have a wideband lambda sensor installed, with A/F display. With all of my mods (ported heads, headers, full exhaust, modified intake manifold), I was surprised that the ECU is able to hold 14.7:1, during closed-loop operation, but it's really fat under heavy load.

There is no Unichip tuner close by. I signed up as a tuner and bought the software, etc.
I was set up to map the car on a local dyno this Fall, but they closed up shop.
With winter closing in, I'll probably be mapping it in the spring.

I had a hard time getting the wiring diagram, from Unichip, but I finally did get it working.
