I've decided to continue on with a Megasquirt project I started last year then got sidetracked trying to get a carbureted system to work on my 242. I set my MS 2 board up for driving one canister style coil directly using an LH 2.2 distributor because I was trying to keep things as simple as possible. Now I'm having second thoughts about using a distributor after reading up on coil-on-plug ignition systems and the benefits they have.
My questions are 1) is it really worth the trouble to convert to coil-on-plug for a street driven car that MIGHT eventually see track time some day, 2) is there a cheap salvage yard way to convert to COP and if so which cars have crank position sensors and trigger wheels that fit the old redblock engine, and 3) I assume I'll have to add 3 more coil drivers to my board for COP (right?); what other things would I have to do to the board go from how I have it set up now to COP?
I've read the "K-Jet to Megasquirt" write-up which was educational but the author suggests using some Yoshifab parts which are pretty expensive which I'm not really interested in. Also the author suggests using GM coils with specific parts numbers, but won't any coil pack work with the MS, such as a GM 2.2 engine coil pack? If I do go COP I want to use parts that I can adapt to the car and NOT make it look like a cobbled together hastily put together system when I'm done. Sometimes I think it's a fools errand to try to take an antiquated engine and make it into a modern one: IMO if a person if going to have to go to a bunch of expense and trouble to do this it would be wiser just to switch to a more modern Volvo engine (such as a whiteblock engine). At the very least I want to have a fuel/spark system that is better than the crappy Bosch Jetronic/Chrysler systems that Volvos used on redblock engines (which have left me stranded); any benefits beyond that would be icing on the cake.
I greatly appreciate any thoughts and information on this subject.
