"And this one is just right" ~ Goldilocks
UPDATE - With the octane boost the thumping is now gone!
It was raining on the way to work, so unless it's humidity related I'd say that the higher octane has temporarily solved the problem. I added about 1/3 bottle of
and brought the tank up to about 1/3 full to keep it concentrated.
So, is this a timing issue or a fuel issue I can tune out?
Timing- I was super careful during the rebuild to set it correctly (triple checked). Plus, other than this it pulls like a freight train- super impressive. I asked for drop in cams, so not as precise as dial-in, but should be close if not spot on.
Fuel- I just got the PC5. I plan to install it this weekend and load the tune my tuner did for me. It was converted to TuneECU, which is what's in there now. I also have Auto Tune coming in the next few days. My hope is that for what I paid for those used, I can fine tune it further for less cost and time than revisiting the tuner. I brought it in with a borrowed PC3 that gave him some trouble. Also, I remember him saying that the PC5 would allow fuel adjustments to individual gears, which could be good for solving this situation. Finally, someone here earlier suggested I get the POD-300 and I found it on sale new, so $hiite, why not. Now to learn how to use it all. Very glad it is not the Flux Capacitor or Torsional Bearing.
Thanks to everyone for their ideas and help. I think we have it diagnosed, at least.
