'74 C10 w/ Tuned Port Injection on a 350 MRE project
Posted: Mon Dec 19, 2022 3:36 am
My second EFI project.
I put the Tuned Port Injection intake from a '85 Corvette on a '74 Chevy C10 350.
Doing pretty much the same thing I did on the 240Z. Using an HEI distributor and conditioning the tach signal coming out. Using an MRE and driving 2 injectors per injector driver.
The goal is driving it around by Christmas day. Last night we got it running with the wiring just taped together. The timing is way out of whack (8 degrees after TDC) and I forgot about all the vacuum ports, but it we lucked out and it fired right up after I sorted out a tach signal issue.
So this was even easier the second time. The tach signal issue was entirely my fault with a broken solder joint. The ECU/Tuner Studio took me only 20 - 30 mins (already installed of course) to get set up and it was the last thing I did before we got the truck running. MAP input, tach input, injector outputs and generate a VE table. Good to go.
Hopefully I can get it the rest of the way this week.
