Take a look inside my “Tune the Trilogy” Holley EFI training course in this video, as we diagnose and repair a bad oxygen sensor.

Good work joe
here for broken spark plug pics
DUDE NICE BEANIE
If your on the fence about Joe's course, it's definitely worth it.
Woah live comparison data, that's slick!
Great info thanks
I'm not on the fence about Joe's course I do need to finish this engine and get it on a dyno with a carburetor to make sure everything is correct. I've heard some pretty bad stories of people trying to do a first start with EFI. That won't be for awhile unfortunately.
BTW this problem would have been very hard to find without a Dyno.
I understand closed loop can save your bacon but it can also screw you over big time haha
Joe's videos are the best!
What you’re saying makes perfect sense however I like to take a different approach with my own car. I give closed loop and learn a bunch of authority, my logic is, when something goes wrong, it goes a long way off making it very obvious something is wrong straight away, if it’s only allowed to go 20% it might not be noticeable straight away and be 20% lean under full power and melt everything.
Was this a TermX car or HP/Dominator? You said you swapped from a Bosch to an NTK sensor. I know the TermX harness has the right plug for the NTK, but I thought the ECU just couldn't run the NTK sensor.
Can you go over the different NTK sensors? Have heard about Lab grade vs other ones. How many NTK ones are there? Have been wondering if one from rockauto would work with EFI systems. A lot cheaper than getting them from Holley or Fueltech, etc.
I have a Terminator X system and I'm using the narrowband bungs on my longtube headers as the location for my Wideband. I feel like I've got a heater control strategy issue. Are these safe to run at 9 or 3 o'clock? Or do they need to be pointing down just a touch?
