FYI: Holley HP ECU to Racepak IQ3s
It was a bit more of a frustrating and lengthy path that I would have hoped for to get this figured out, so I thought I'd help others out by spelling it out as clearly as I can.
If you intend to run a Holley HP ECU with a Racepak IQ3s - this is what you need. Holley part number 558-412 (~$70) Racepak part number 280-CA-EFIHOL (~$75) I had a range of responses from Holley tech from, "only need 558-412", to " you need 558-412 & the V-net module ($375)". Some of the confusion is in the fact that earlier Racepak dashes required the V-net module ---the IQ3s does not require this item - just these two adapter harnesses. Maybe this will save someone else a lengthy conversation. Ultimately Racepak tech got me squared away. I asked them to send a message to Holley's tech group to clear up the confusion as well. |
I had a some difficulty importing the monitored channels as well. Racepak customer service did well and remote logged into my system and had it recognized in no time. The settings weren't obvious.
Took some doing but I've been using my racepak for probably 5-6mo with no issues. |
