Holley Sniper EFI systems - Troubleshooting help page

How did you do your firmware update? I just did mine but it took me forever to figure out, even after watching the video. And it took me a few tries at saving a configuration to the SD card and finding it on the handheld. This stuff needs to be more user friendly.

I used my years of experience playing with file relocation....after watching the video several times. I paused and tried to catch what was said and done.....but in the end I just winged it. It worked.
I did accidentally re-install the SD card with the ignition on.....nothing happened, but it goes to show how easy it is to slip up and make the mistake.

This is the video I chose to follow.....,he seems to know his stuff, but I did have some trouble with his accent and how fast he talks.

When I first loaded the file I got an incompatible touchscreen lol. This was after I deleted the old files. C'mon Holley!!!

That happened to me also....I repeated the exercise.

Try this video I watched last night....a little clearer....

I will chime in on questions as well. For those that don't know, I'm a Holley EFI dealer and tuner. I've gone to Holley dealer training and have tuned a bunch on my dyno. Most of the issues I see are from guys not following instructions and not grounding properly. The positive and negative leads must go directly to the battery, no ifs ands or buts. The engi e must have a dedicated ground going from it to the battery. I'll help as I can and to the OP, great catch and fix.

Can you tell the +12v switched ignition source you used?

Can you tell me what my options are for a +12v switched source. I have a 1972 Dodge Charger 340 with electronic ignition.

The 2 wires coming into the ballast resistor. I use a relay those wires turn on.
