Hello Graham, I like the Spitronic because it is almost p&p. It was originally designed and built around the 1UZ-FE and is great for what I want out of it. I found the programming side difficult but that is due to me being used to Haltech, Autronic and the like.. Like all stand alones, the more yopu play, the easier is gets as you learn.. Ill tie you up with the blokes from Spitronics, please shoot me a blank mail -barry at gsab dot co dot za. Cheers Graham, Barry.
