Holley II ECM, is it worth the money?

[SundanceKid805]

So I you found a Holley II ECM online and its not a bad price. I have a 1988 Plymouth Sundance, 2.2 carb, and I'm wondering if this would function or be worth buying. I do need some tips on tuning this engine, I wana keep it for a while. Any advice?

Last carbureted car manufactured by Chrysler was the 87 1/2 Omni/Horizon.
Your Shadow has to be TBI(Throttle Body Fuel Injection)

never seen a carbed P-body

L-bodies and the 2.6 chryslers FWD cars were the only carb cars from chrysler

not sure about the early 84 base daytonas

that Holley II ECM is more than likely just a stock rebuilt computer. Holley not only made performance parts, but they also were in the parts remanufacturing buisness as well. even if it were a performance computer, on a TBI car like yours the power gain would be minimal at best.
you could just bump the timing up a couple degrees and run mid grade or premium fuel and get a small boost in power, like 2-3 Hp. to get more power out of an N/A car you really need to make mechanical changes to the engine. things like having the head shaved to increase compression, a different cam, either porting or swapping out the intake manifold, swapping out the exhaust manifold for a tube header, etc.

Oh ok. It jus looked like a carb. I'm an idiot.lol So it would make sense to jus turbo charge it then? I never had a one these so I'm learning as i go.

Ok. Well this one says it goes.inside and I know the comp is under the hood, that's why I asked.

if you wanted to stay N/A this is what i would do-

swap out the TBI for a 1 piece turbo intake setup. going from TBI to multi port fuel injection will be more efficient, and the 1 piece intake ports were desinged to flow the same amount of air as the 782 head's ports. the flex fuel vehicles ran this exact setup even though they were N/A. you will have to use a turbo computer that is reprogrammed to run N/A, alont with a dual-HEP turbo distributor. Shel-Game can get you a computer, but you will have to add several wires to the harness to make it work.
from there add an exhaust header, those are still avaliable new and arent expensive.
i would also deck the head, and get a cam with more lift and duration to take advantage of the increased compression.

with all of that you would have a VERY healthy N/A car that will be a lot of fun to drive, i've been kicking around the idea of doing just that if i find another good rust free body to play around with. lumpy cams and high compression is almost as much fun as a turbo, sounds cool as hell when you roll up to a stop light with the cam loping away.

if you get a 88-89 turbo Shadow or Sundance as an organ donor you can just plug in everything and go.

Has to do with how nice the car is and what your willing to do for work and so on. A great car in great shape it is worth it. If the car is a $300 beater then maybe just get a turbo car lol.

The TBI is also rock solid as a daily driver, they run for ever taken car of. So I would look at junk yards for a new computer and also look at the fault code threads for learning codes and so on.

Another option is a 2.0 swap or a 2.4 swap and megasquirt, basically a piggy back computer so your not getting an organ donor. Either way the engine is coming out for a turbo swap, the TBI won't survive long.

Megasquirt is a full stand alone ecu. only thing you need to run with it is an external voltage regulator from an 80's era dodge truck or RWD car.
