Sniper EFI - Advantages (1 Viewer)

[Alan Kiecker]

What are the advantages of converting from the carburetor to the Sniper EFI? What things would I notice in driving my FJ40? Starting? Gas Mileage? Drivability with elevation changes? Drivability with temperature changes (hot summer weather to cold winter weather)?

Starting, throttle response, elevation compensation.

I will caveat this to say: if your engine isn’t in good shape and a good tune before the sniper, it will likely be worse with the sniper. I think a lot of people have a poorly running engine and instead of doing the work to properly get it running, they throw a sniper at it then say the sniper is junk.

Not saying this is your case, just putting that out there.

@Skreddy pretty much nailed it. It is a great upgrade.

Biggest thing for me is I take mine to Colorado and wheel it way up at elevation (as high at 13K). Did it with a carb a couple times and it is possible, but requires alot more work. Always making adjustments and starving out on steep inclines is a real problem. The sniper relieves those issues. Still need to add some advance, but that's the only high altitude tuning I have to do now.

It starts almost immediately.

Fuel economy is not something I track or really care about in this vehicle. I can say that I went wheeling a couple weeks ago and still had a 1/4 tank after 8 hours. That's with about 1:20 of highway and the rest on the trail. 16 gal tank.

I do carry all the spare parts: filters, pump, injectors

Starting and driveability under different temperature scenarios is the biggest advantage for me.
The engine starts up all the same whether its 100 degrees or below zero.

Most peoples carburator is so bad you will be able to see a noticeable difference on a healthy motor.

My 1998 FZJ70 has a “modern” carburetor and there is no way I would swap it for a Sniper even though I’m a huge fan of the Sniper
