RE: [Chrysler300] F.I. D on e-bay

Continuing the '58 F.I. discussion - about another 300-D -

A couple years ago, when the generator on my F coupe was misbehaving, I was referred to a fellow who lives near me, Joe Serritella, to rebuild it. Joe has many decades of experience, and was rebuilding a starter for a Twin Six '21 Packard when I stopped by. Having sold his business, he works out of his garage and basement. He also checked out and reset my 5 generator regulators (3 for my F and 2 for my '64 1/2 Mustang) after testing them, finding that all 5 were grossly miscalibrated, 2 of which were brand new.

While visiting with Joe, he related the following story, about a fuel injected '58 300-D he had worked on back in the day -

Hi Noel,

Good hearing from you. We are still in Arizona and will return to Chicago sometime in mid-May, that is if it stops snowing there! Let's plan on getting together when I return.

Regarding my 300D F.I. experience: The car was a white convertible with a blue & white leather interior, owned by one Harvey Pohlie (not sure I'm spelling his name correctly.) Anyway, he mentioned buying the car used and after having nothing but problems that were seemingly unsolvable. At that time my only F.I. experience was on diesel trucks and one Corvette, all of which were mechanical.

After looking at the car I asked if he knew if the F.I. was an aftermarket dealer installed set-up, as it did not look factory to me. The distributor cap  appeared to be a standard AutoLite, modified with 8 small terminals coming out the side. To my recollection the cap was drilled and tapped to accept either 6-32 or 8-32 studs locked nutted on the outside. The whole installation looked aftermarket or at best a laboratory prototype. It was during the warmer months of 1958.  I seem to recall he bought the car used but with very low mileage. Claimed the deal was so good that he couldn't pass it up. He swapped a 1958 Corvette 290 HP for just about even money, as  I recall.  It was loaded and may have been a Chicago Auto Show Special - not positive of that fact. It was a gorgeous car and above 40 mph it was fast.

Ultimately I was paid to remove the F.I. and replace it with a stock dual 4-barrel carburetor set-up. The old F.I. stuff was put in two boxes and left in our shop to be later thrown out.

I would be interested in finding out if the car still exists in someone's collection.

Regards, Joe

Do any of you have any recollection of this F.I. 300-D convertible?

Hi Carl, cannot thank you enough. From this, it started as vacuum tubes, then progressed in R&D to transistors , 4 generations were mentioned.. Inferring from the operating description , actually a very simple thing electrically. They seem to be just adding varying amounts of resistors in a set of non linear sensors of ~ 5 parameters, in series, to an RC circuit that is controlling the injection pulse width. 20PSI rail, solenoid injectors(!); then a power amp, and a distributor to each probably 12 v injector..probably a roller contact. Same as today, in a way, but today a computer with look up tables is far more accurate today, than building curves into the sensors . But ideas are perfect, 100 % on. Correct idea but immature technology has been the bane of leading edge thinkers from the first wheel!

I am hopeful one of us gets a real schematic. They were understandably holding the real workings secret when it was new..probably patents filed. Good ones I think!

Analog circuits are surprisingly resistant to spike noise, so probably not EMI as much as widely varying voltages on a generator system, severe temperature drift effects all over the device and the engine temp /outside temp etc…

Nice try, we give it A+

John, the attached might be helpful from an EE standpoint. The modulator (brain) was solid state. The system was inadequately shielded from EMI. Agree, wish we could find an actual schematic.

Really interesting what a real FI car might get. Even if an obvious wreck now….gotta like the Ford blue hemi and yellow wires, spliced radiator hose. . .Wonder if he has the FI unit in an old box?? I have tried for years to get a wiring diagram of what was in them, how they worked, EE hat on .Really curious. Heard they had vacuum tubes, that would be something. Old enough to know about those, aka Philcojohn .That would mean a vibrator power supply in 57. Maybe very early transistor stuff. Bendix had mil connotations……

Does VIN id a fuel car in any way? Probably had a unique distributor to pick up needed signals…

Roster shows it is/was John Follie’s car, the junkyard guy in Williams, CA that is on the Forward Look site a lot.

I have sold him a few parts in the past.
