My situation's even worse. I dont have a manifold shield as I'm running the J's unit - so might have to think about exhaust wrap if things get abit hot down there..

It won't make any difference to the AEM ECU. It won't start using the wideband until the preset pressure, temperature and RPM targets have been reached. It takes a good 30 seconds or so to warm up and give you a decent reading.

ok cool, I didnt know that. So cold startup is closed loop for the initial part?
Trunkz, i would get your exhaust ceramic coated as the wrap will go nasty after a while, it works but just doesn't look very nice after a year or so.

markforrester99

You can change the settings to whatever you want regarding when closed loop and O2 feedback start. I have it set at 50c so if the coolant temperature is below that then the O2 sensor will be ignored and no fueling corrections will be made.

Ok, i will ask Chris how he set it up.

johnckeen

Can i run the three gauges(UEGO, Water, Oil) from the one 12v wire coming from the battery, same with the earth too?

Trunkz

Yes - get a little fuse box so each gauge runs its own fuse.

johnckeen

What size of fuse do people normally use?

Is their a name for these boxes in the car world? As I need to buy one, or even a ebay link!
