That heavy voltage draw in cranking could be from worn bushings and brushes in you're starter motor, never hurts to pop them apart an clean the armature and such. 25-30$ in small parts can often bring them back to life for another 50 years

You need to find a better ignition source for the pink wire. Mine did exactly the same thing until corrected.

Thanks for posting this. I haven't seen many videos talking about these systems over the longer term. I'm having one installed in my car, though it's been in for almost 2 years, so I'm hoping to find out in the next couple months or so how well it performs on my own car. I'm having the Sniper 550-866K small bore unit installed to replace the Chrysler lean burn carb system.

I think it's like anything electronic these days, they're hit and miss, but I've personally had good luck and I think my car runs well with the Sniper unit. I think it would run a little better with some small things like an upgraded alternator and such, but that's minor stuff.

I added twin cooling fans to my Chevelle and boy do they draw the alternator down. A good yellow top optima or really any deep cycle battery designed to carry additional loads will help your alternator and buffer the momentary dips in voltage when fans kick on. Does it matter if the ECU is disconnected from the battery for long periods? That doesn’t erase any settings?

Think u are right could also have lower fuel preasure due to dead battery too . I'd try starting it after it has like 12.5+ volts. U should get a battery tester to tell u how many amps the battery has. I use one everyday at work.

I'll have to check my fuel gauge, I think it's okay though.. could be a little lower due to my small leak. I think this battery is starting to see it's way out, it's holding a charge fine, but I think it's amperage is dwindling. A new alternator wouldn't hurt though, that's for sure. I need to find someone that can rebuild it with higher amperage.

I have the MSD atomic system. If it sits for months it will start immediately then die. Will do it twice before it stays running. If I cycle the key 2 times letting it prime each time, it will stay running on the first try. A friend has the holley system and does same thing. Your fuel mileage improvement is because your carb was running richer than the sniper.

I adjusted my target AFR's before selling the sniper (bumped them, the sniper seemed to read richer than it was actually running) and the car ran a TON better. Probably lost the gas mileage.. never checked. lol

60 year old wiring is always been the problem that I have seen. Was the holley system wired into factory wiring? With electric fuel pump, fans, fuel injection, the entire wiring needs to be modernized.
@RamblinGarage
@RamblinGarage Жыл бұрын
Holley has its own wiring harness, power and ground are direct to the battery. There is a wire that is tied into the key in the hot position, which generally goes to the hot side of the coil. I have not checked to see if I have 12v constant there, that could also be causing some of my issues. I'm upgrading my Pertronix unit, which will also need 12v constant, so thats why I havent dug into it too far yet.

I've abandoned the project for now as I'm thinking of going more of the restoration route on my car. I do have some spacers that are cnc cut and made of aluminum if you're interested, but they weren't cheap. They were about $130 shipped when I got them, I'd let them go for $120 if you wanted them.

if you totally disconnect the sniper from the battery you clear the memory to the ECU requiring it to go throw the learning again, try driving awhile and let us know if it improves?

I thought it stored that tune on the SD card? I don't think it should clear tuning preferences after sitting unplugged.

Just like all computer cars when you disconnect the battery totally it clears the data causing it to go into a limp mode then you need to drive about 30 to forty miles to recover data before you can do an emission test. If you look at the instructions, you will see the ECU has a direct connection to the battery for constantan power. It does not reload from the chip unless you reload it.

I see you have return springs on the throttle. Is that in addition to the spring on the EFI or did you remove the EFI springs and add your own. My Sniper has a very stiff spring and gas pedal as a result. Just wondering if you had that problem.
@RamblinGarage
@RamblinGarage Жыл бұрын
Mine are in addition to the springs in the throttle, my pedal is a little stiffer, but it's not bad. I will say since it's a little heavier, it has exaggerated the touchiness at low throttle, so I have to look into getting that fixed.
