I've been tuning Duramaxes with EFI Live now for a few months and I have to say its an amazing product for both tuning and diagnostics. I happened to have a newer Case IH Quadtrac 450 in the shop and couldn't help but notice the Bosch ECU on the side of the engine. It got me thinking that with the right bench harness (these tractors all have manufacture specific data ports) they could be read and tuned with EFI Live. Anyone attempted this yet or had any success? Attached is a picture of the ECU tag.
