Megasquirt of a '75 450SL. MS1 v3 board
Getting into this project now. I've got the board pretty much built, and most all of the sensors accumulated. Plundered a Saab 9000 at a junkyard for ICV and TPS. I'm trying to hook up with a welder to fabricate a plate to put a wideband O2 sensor in place of a EGR valve on the manifold ('75 is the first year of the cat + exhaust manifold).
I originally planned to go fuel only, but it looks like the spark control would be not too much more to do. I need some input on how / where to get a crank sensor wheel attached. The harmonic balancer has 2 notches that need to be kept clear for access to two water pump bolts, so that is a complication. Does anyone have any suggestions or advice?
