Thats is true but you set targets for AR and idle when warm and when wide open, every engine is different, and this target was my biggest problem as y blocks are differentThe self-tuning software will only get you so far. If you want every last bit of performance manual tuning is needed. I download logs to a remote tuner who can optimize the tune on the car remotely from his house in Kansas.

and is a little bit of a pain to do all the input
, timing readings on mine there is no adjustment as timing is controlled by the MSD brain. so at 15deg idle and gets to about 38 degrees when cruising. The only other is at what temp the electric fan kicks on and if you want the fan to run when you turn the air on.
They say it takes about 800 miles for the computer to fine-tune and the first 500 miles
I was not happy but after 500 miles that car never ran so well.
I spend more time watching the computer than the road, I'm addicted to the screen as
it tells me everything the engine is doing.
