.....it seems like guys will always mess with the tuning, and the madness never ends.
Just like I said, engine dudes are never satisfied. From the negative viewpoint, it's like an addiction, on the positive side it's a hobby that keeps you busy with endless possibilities.
Jimmy, here's the basic scenario to shoot for:
Run slightly rich for starters. This is the safe approach, running lean will burn up your engine.
Tweak idle for good starting, idling, and transition to off idle.
Tweak for smooth, steady, acceleration
That's basic carb tuning, too. With the above scenario you're good to go for years and years, no need to mess with anything. At that point you stop listening to and reading all the threads that the motorheads post. If all you really want is steady reliable running like a passenger car. This is all I want. No more roadside breakdowns, no worries about what's going on under the hood, hop in, drive, enjoy life.
Others regard these cars as "toys" and beat the crapp out of them sports cars. Those guys will never stop tinkering and replacing parts. Hey, that's okay, each to his own.
Nobody makes aftermarket stuff that makes your car run like a daily driver, there's no money in that, cars are already designed to be reliable daily drivers. The problem with many of our 50 year old Opels is that they often aren't reliable, trouble free, daily drivers. FI can make them that way. We're right on the cusp of it being possible to make any car FI reliable. The remaining stumbling block is that many old cars don't have decent FI manifolds. Hopefully Charlie's mass produced manifold will work out and the last piece of the puzzle will be in place.
Basically, you just have to be patient and wait for the new manifold to pan out, then someone will come up with a decent tune for the 3-4 basic CIH engines and everyone will copy it. Sure, the tune will get refined over time and even better tunes will get developed. But, it's easy to upgrade to them. Copy the tune to a thumbdrive, load it to your ECU, go for a drive to see if you like it. I did this like 20 times last year, it took like 5-10 minutes and I never had to touch a wrench. Now, my effort failed due to a quirk of the manifold shape and the forcefullness of the injectors, but I almost had it. I was this close: ( ). If I had been using a normal FI manifold I would have been done and up and running in a month or two and I'd be driving modern FI right now.
