As I understood the old Camaro system it would enter into the lean burn mode only under special conductions like a light throttle, and light load, change either of these and it would switch back to normal A/F ratios.
I do not know if there was any other changes like with the timing..
The Jarcar Digital Fuel Adjuster has the ability to be mapped to the settings of the MAF so my idea is to cause the unit to output a signal that tells the PCM the car is coasting like under a light load which should (if I understand the programing) lean out the A/F ratios to the engine, producing a lean burn, any change out of this idea range of light load should put it back to stock.
Also a selector could lock this feature out unless switched on so it would be a user selected use.
Now doing one with the unit I have is OK for me, but I want to offer these to my friends and other thus the need for a replacement system.
