Makes sense, I will just go into slice and dice mode as the Holley Terminator seems to be the best option for me after weighing all of the factors.Extra wires and customizing seem to be part of the game when modding an old analog car to FI. My present car has a 1990 Motronic system and I had to eliminate half the wires. There were a lot OBD1 diagnostic wires, plus ones for controlling a modern electronically controlled auto tranny, anti-lock brakes, etc., that all had to go. If I had decided to run my oem system with an aftermarket controller, I would probably have had to cut off many, if not all, the plugs and graft them onto the new system's wiring harness.
I like this idea. the passenger side footwell is the future planned home for my Opel GT ECU.Consider mounting your ECU and extra wiring in the passenger side footwell, which would require cutting a decent size hole in the firewall on that side. I'm customized and don't have the heater there anymore, so I have plenty of room to mount all that stuff behind the dash.
I acquiesce. After a bunch more research, I agree with you, there is not that much of a difference and I will just go with readily available / compatible injectors. I have not yet acquired the fuel injectors. But that day is coming soon. I will focus more on getting the lbs/hour right and fabricating my fuel rail.I understand your fascination with the latest, coolest, injectors, but, remember: You're rigging an old, weird, car for FI and you're making your own unproven manifold design that may or may not have the optimum injector positioning and general flow of air. Plus, you're thinking of throwing a turbo into the mix? You've got all sorts of variables going on and almost all of them are unproven. The older, larger, injectors were used for decades and nobody complained, I hardly think that the latest gee-whiz injectors would make any noticable difference. The oem FI had the injectors squirt right at the head ports, your concept has them a few inches farther away, Holley Snipers have them all the way at the beginning of the line before the throttle plates, my system will have them just after the throttle plates, carbs introduce the fuel before the throttle plates and various carbs set ups are near and far from the engine, and they all seem to work just fine.
I downloaded the free Holley Terminator X software, and it is actually quite helpful in figuring out what is configurable. Also, the 4th Holley call I made I talked to someone really helpful. He pointed out that on their web page if you select the picture of the item you want and scroll down to the bottom there is an area called "Tech resouces" that has all kinds of info that was helpful for me designing my system.I contacted Holley late last week to ask how to configure the system to run the spark and injection like a 2-barrel Holley Sniper. They said to wait 3-4 days for a response and I'm still waiting.
My research indicates that the main wiring harness that comes with the Holley Terminator X does have a place to plug in knock sensor, but the knock sensor itself doesn't come in the kit.Are there knock sensors also?
Agree! This is a fun project with much problem solving on the way.But figuring all that stuff out is half the fun. 😀
