IQ3 Setup 

no. will cause engine to blow up. immediately

Your best bet would be to speak with racepak directly www.racepak.com/

Haltech yeah... they have no idea.... I'll be throwing the racepak in the trash. I do not recommend racepak

James Moore wonna sell it?

Doug Lesley sure... and I have two cables for a vipec edu also.

I’m trying to wire the haltech IQ3s, I’m trying to wire to the LS1 ecu but I don’t get readings from the coolant, or oil pressure, or rpm signal, now to configure the dash the ls1 uses a 4cyl 4 pulse signal, also do I have to use the 5v reference and ground for the sensors???
