Looking for advice or thoughts on O2 sensors and what alternatives I should consider. I am currently wiring up a tuner series wolf ecu building a new harness and had planned on using wide band sensors, yes Gloverman I am paying attention and yes, I should have bought a Link.
I just can’t get any information from wolf support and their documentation is seriously lacking.
Wolf previously claimed they supported wide band sensors and wires were there but they actually didn’t and I can’t confirm if the current tuner series does, the only documentation is only for the older ecu not the current one, there appears to be wiring for one wide band channel not two, although it supports two narrow band sensors, but no wiring for heaters and was told the heaters also need to be controlled by the ecu and not just 12v from the battery, can anyone confirm this?
I currently still have the crown log manifolds which have single wire o2 sensors which has a shielded cable back to the ecu. I am guessing they would be original 89 ones as the motor has only done 96k so will probably need replacing. So looking at what to wire it up for?
The one wire sensors don’t seem to be as common these days and it appears most 1uzfe use a four wire versions with heaters, so also looking to future proof.
Wide band sensors probably wouldn’t work for long in the current sensor locations in the underside of the log manifolds, so I am guessing I would have to located further down the exhaust where it runs in a long balance pipe and just use one wide band sensor on the off chance the ecu does support wide band, or try to use later type of narrow band sensors, I don’t really want to buy an additional wide band controller.
I should also mention there are no cats in the system. so any advice is much appreciate.
