Aug 5 2005 - Starting to gather information. Downloading Megasquirt manual.
First subgoal is to master 18F6722. I am more experienced with the lower end 16F family. Reviewed "silicon errata" of this chip today. Need to better understand the limits of this chip by using an engineering kit issued by CCS and by trying to upset it.
Second subgoal is to carefully review Megasquirt manual and AVR code. Need to better grasp operation of ECMs. Need not use "bleeding edge" version of Megasquirt II.
Have been reviewing wide and narrow band Oxygen sensors. Scared off by cost of wide band but attracted by faster response time and wider range of operation.
Target is a stock Caprice classic with a 305 Chevy engine, turbo 350 tranny. Condition is "rough" so I need not worry about keeping it stock. Contemplating using an electronic carb, but considering the problems with calculating mass of fuel this may be fool hardy. Would like to keep most of the system as close to "stock", accepting mediocre mileage and performance as a trade off. Would also like system to actually work so may toss in the towel and convert to TBI.
Will decide after I review above. With gasoline at $2.50 a gallon I am not expecting miracles but would like a little break on mileage. Also just want to do it.
