It looks like the computer is not talking to the o2 sensor.

Do you know if it's a computer problem, or an O2 sensor problem?

We think its a computer problem. We changed the o2 3 times. We have another unit to put on and see what happens next.

Well good luck, and I hope you start to see some cooperation out of it soon.

Welding on the exhaust system while the battery was still connected, short circuited a friends Holley sniper ecu x2. Was told by Holley tech that the negative post should be disconnected.

I didn't weld the bung on the exhaust I used the strap on.

That's good news

Maybe at some point when you get things ironed out it would be a good idea to go back and weld a bung on. Those clamped on 02 bungs have had a reputation for leaking and sometimes giving false 02 readings.

Let us know how it works out now.

That's good that you can now evaluate how it runs with the Sniper. Any idea if the original unit is repairable? There's currently 2 dead Sniper threads here in our small sample. Hopefully you'll have better luck going forward.

I will call Holley tomorrow to see if I can have it repaired or buy a new ecu.

Is the ECU removable, or does it involve changing out the whole TB?

I talked to Holley today and they gave me a call tag to send back the old unit to be repaired for free. Thanks for GREAT customer service Holley.

That's pretty BA of Holley considering it's a used unit! Good on them!

That should be fixable without too much trouble. Hopefully you're up and running on your own unit soon.
