C950 upgrade confusion, 550-604 or 554-113?

You need to read the Holley EFI instruction manual. The Holley EFI system must use the Holley EFI WBO2 sensor. It's a proprietary wideband O2 sensor (LINK), specifically made & calibrated for Holley EFI. However, Holley's 534-199 4' long WBO2 extension harness is compatible.

So this is actually an Avenger that I bought used, but I'll be using a laptop, so in essence it's HP. Is the Innovate LC-1 that was in play with the Commander 950 not needed with the Avenger/HP? I see the wideband connector is entirely different on the HP as compared to the Commander 950. What style of wideband O2 sensor is used on the HP? The brand new one I bought for the Commander 950 (along with extension) is money wasted I assume? I have no idea if the used sensor with the HP is any good.

Thanks, that sounds good. What option would I need to tick with this crank trigger?

[Danny Cabral]

You can run an MSD crank trigger kit with Holley's 554-118 Hall-Effect crank sensor.
Holley's 554-118 direct replacement Hall-Effect crank sensor (¾"-16 threaded sensor):
http://documents.holley.com/199r10633rev.pdf (Holley 554-118 Instructions)

Or you can run the Holley EFI 36-1 crank trigger kit (Hall-Effect sensor) for small block Fords:

The Hall-Effect crank & cam sensors are wired as shown in the Holley EFI Wiring Manual:

The magnetic crank trigger? How is it connected? Is there a loom ready made to join it? What option would I tick?

[Danny Cabral]

Yes, the Terminator EFI can use a crank trigger kit.

[SCP440]

If I ditch my Commander 950 system, can I use my crank trigger with the Terminator system? Looking at the online instructions there is no mention of a crank trigger.

[Danny Cabral]

Yes, you can update straight to V5 or V6.

[makemeknowit]

I'm buying a used HP harness and ECU. I think it has V3 in it currently. Can I jump straight to V6?

[Danny Cabral]

I prefer the Terminator EFI: https://forums.holley.com/showthread...762#post208762 (Related Forum Post)

I'd think the modern Sniper or Terminator TBI setups would be much better over all than the old low pressure TBI stuff.

[makemeknowit]

It's TBI...

[Danny Cabral]

Is your current C950 EFI system TBI or MPFI?

[makemeknowit]

Would I be doing myself a disservice if I pulled all the C950 stuff and went with a Sniper instead?
