First one to 60 wins?
Let me get out my calendar. Let me know which week you hit 60 and we’ll compare notes on the winner.
This is a very good point.

Never been in a situation like that and dont believe I really ever will. Though if I ever have problems with my carb again (after I get my JimC rebuilt back) I may say F-it and grab one of these Sniper kits. Considering the cost of the carb (which I got for a steal) and then cost of the rebuild, I am already 1/3 there. But everyone says how awesome these trucks run after the JimC so I am excited to see how it turns out.
Mine still runs well, but still has the problem of hard start after sitting for a while (1-2 weeks) and the same issue I have with my KLR. so expected I guess. Driving it around on weekends it does preform real well. No idea at high elevation yet and I have not been off road with it yet.
But like others this thread is getting off track.
I think for me the sniper kit is interesting and the install seems rather straight forward. I am still up in the air about it. Only because carbs are rather simple and need very little to function. There is a reason my KLR650 is a carbed vehicle, simple to repair anywhere.
That said the EFI does removed the need for a huge number of things.
Heat riser in the exhaust, even more vacuum hose, no carb fan etc. Although it will add the electronics.
I see hit and miss from others in the muscle car and truck forums, but overall better experience than the the FiTech kit. Most is around the customer support and the lack of spare injectors (you need to send this to Holley).
How has the experience with Holley been, anyone else have experience? I know Affordable Fuel injections is good. Holley being such a large company, should be better, but being a large company could change easily with outsourcing.
I know my old Holly carb on my car was a beast and never gave me any trouble.
@Dustin Messina Have you had to call much other than the relay? I was chatting with the only other person I know who had a sniper kit installed and he really likes it, but had a shop install his.

Putting my shopping list together and hit a wall with the Downey adapter plate. Any source for this? Simple enough piece...could likely make my own if I could get the specs..dimensions...scaled drawing.
He still sells them but I will send you a PM
OK you gurus of Fuel Injection.
The OP is not using an electronically controlled distributor so the ECM is only controlling fuel.
With the 60 series electronic distributor how is this an advantage or disadvantage. IF someone were to do this would you not want a distributor controlled by the ECM?

I was talking to Howell about this since they don’t do distributor control on their setups.
His take was that without a knock sensor, computer control is a waste of time. You would need a ton of trial and error to get it to run as good/better than the factory vac advance setup.

Interesting information Cam! I think that the AFI unit CAN come with a knock sensor but that is the only one I remember seeing.
AFI doesn’t for sure (edit: I missed “CAN”. They might be able to.)
99% of the magic is in the rest of the system.

Since we’re also talking about JimC carb rebuilds, can someone give me a ballpark on what he charges to go through a typical 2F carb?

Using something like a Mallory Unilite would certainly be better than the OEM unit. No idea if anyone makes one that works with 2F.
@ $400 for rebuild + 4-6 week turn around.
Be prepared to tell him your setup..desmog or smog.
Nice, thank you.
So there is there no advantage with any of the 3 systems (Sniper, AFI or Howell) to have the Distributor controlled by the ECM?
Assuming the computer adjusts the timing according to the map reading, the advantage would be if you frequently change altitude.
If you don’t, you can just use the appropriate vac advancer port on the dizzy and switch between high & low as required.
When the ECM controls the distributor it advances or retards the spark as needed based on driving conditions and feedback from the sensors (O2, MAP, etc.) so it 'should' provide better drive-ability, fuel burn and reduced emissions.
I pieced my system together using a Howell computer I found and went with a Performance distributor controlled by the ECM, so I can say for sure that the Howell will control the distributor. I'm guessing they don't change that part of the programming when they add whatever they do.
What I didn't like was the idle with the Howell, it was terrible. I have since put in an AFI chip and the idle is way better. I can't say that I noticed any difference between the two during normal driving.
Following this thread as I'm looking at the Sniper for my 60.
