Re: [Amc-list] Moates' APU1 "AutoPROM" system.... for OBD1

First one's easy -- "small pickup" with 4.3L is the Chevy S-10 and the GMC S-15 (later called Sonoma). That would also include the S-10 Blazer and GMC S-15 Jimmy (Blazer clone). 

Once you get the EFI systems figured out for AMCs of all sizes you might find that you have a decent niche market for sure, especially after I print and article on it... which I'll run first, then pass on to the clubs...  I still don't think you'll get more than 3-4 a year, maybe an initial surge of a dozen or so. The EFI conversion is only good for a driver, not a restored car, though a lot of people or mixing the two -- restored looks, but more modern safety/convenience/performance features. A flat head six with a 1V TBI system isn't exactly a "performance" car, but if it adds 10+ hp, increases economy 1-2 mpg, and makes it much easier to start and more reliable, and reduces maintenance, it's a worthwhile performance increase for $300 or so total. 

EFI will allow longer oil change intervals because it doesn't pollute oil like a carb (which generally runs a bit rich) does, though that may not be a really good idea with the 196 partial flow oil system. Any full flow oil filter system can go from 3K to 5K oil change intervals once the EFI system is tuned properly and the oil is checked and known to be noticably cleaner at 3K. You WILL have to check it first, and an oil analysis would be best before extending. All modern engines call for 5K or more oil changes because the fuel delivery system is that much better AND the oil itself is that much better. Of course us old car guys do have that low ZDDP "problem", but really only for engine break-in or if the engine is run under high load/has heavier than stock valve springs.

ALDL connector and all. GM ECM 1227747. They're really common, but I 
have no idea what the application is other than "1987-1991 GM 4.3L small 
pickup". (My problem is, I do not exaggerate when I say I have NO, ZERO 
knowledge of car models after like 1970; so when I go to RockAuto and 
see 10, 20, 30 different models under "GMC", I have no idea what's what.)

I'm taking notes. I have one immediate project: tune up the classic 
wagon's Howell'ed 232. Then I wanna put the same setup on the 195.6OHV 
American using junkyard parts (Rambler Mentality), then the 70 Hornet 
(258), which, ironically, the Howell kit would have bolted on directly 
and been pretty close to the correct application, but it's the car I 
drive the least and ought to sell.
