Apologies if this runs outside the V8 focus but a friend said very nice things about the LexTreme products so I thought I would ask.
In Dubai I have been restoring a 2 door 1999 manual 90 series Land Cruiser.

It was pretty rough and the wiring was pretty shot, so I found a 2001 donor and we swapped in the wiring harness at the same time as a full engine rebuild and now we cannot get it to run properly. I can get it to start and idle with one ECU but despite trying a bunch of others that should have worked but with no joy.
The shop in Dubai suggest we do a standalone ECU such as a Link. I keep thinking I really would prefer a Toyota ECU.
Does LexTreme do any work with 5VZ's? I was thinking that if they have a package to use the 5VZ in an engine swap this would work well for my particular problem.
Any thoughts or suggestions would be gratefully received.
