I forgot to ask,what ignition system are you running and is the timing controlled by the Holley ECM?

The Hyperspark is controlled by the Sniper.I put a sniper and hyperspark ignition kit in it
Yes I have the hyperspark which I was actually thinking a bit, the motor manual calls for 10 degrees idle 32 WOT for vacuum wouldn’t it differ from hyperspark timing? I don’t remember if it was this forum or my other that said they had a sniper on a 350 with vortec heads, was gonna see what kind of timing they use and what they have it set toI forgot to ask,what ignition system are you running and is the timing controlled by the Holley ECM?
is that your WOT timing? What are your timing values set at on the sniper screen, cranking was one that I wasn’t sure on so I left it alone, I’d like to use it as a reference to mine, I think (not at the truck) idle:10 WOT:32 Cruising:36(I believe) cranking:15(not sure on cause I did not set/touch it I let the sniper wizard do that)I'm running flat-top pistons with a stock deck height and untouched Vortec heads. If I don't run at least 91 octane I get pinging, so I have the timing on my Hyperspark dialed back to about 24° max. My compression ratio calculates out to about 9.7:1.
You can probably increase your idle timing to 18,liven it up off the line a little. Add a couple deg. at cruise. WOT looks like a good starting point,you can bump that up 2 deg. at a time till you get knock then back it off 4 deg. Your starter will last longer if you back the crank timing down to 0I’ll def keep an eye on all that I do run 93 octane in the motor cause that’s what the motor manual calls for, I’ll also play with the timing after a learning drive to see how that works

What’s the knock sensor labled as in the logs, it’s not tied in with stock still is it?Yes,knock sensor!
