i have heard that some 2001 year AMU cars are non-wideband? is that true? Also i thought it was necessary to have a wideband o2 sensor to hook up A/F ratio gauges.....http://www.apexi-usa.com/product_electronics_detail.asp?id=198&pageNum= 1

this is my turbo timer and has a feature by tapping into the 02 sensor signal gives you the 02 sensor voltage and A/F ratio

i beleive JustJeff posted a pic of the o2 sensor signal wire(little black wire) what size gauge wire and what amp rating wire should i use to splice into the signal wire? i know i'll have to extend the one coming from the Turbo timer

O2 output is 0-1 volt

Wideband is 0-5V
Wideband sensors are more accurate, but also way more expensive and typically use a separate wideband sensor in a separate bung.

any recommendation on wire size and amp rating steve? also do i have to use a special connector or just a regular wire splice?
radioshack.com part number 6403053? says for 22-18 gauge wire

You're only dealing with 1 volt, almost no amperage. That sounds fine. i didn't even use a connector, but placed the stripped end in the socket and plugged back together. It's worked fine for 5 years now!

sweet thanks again!! hopefully it works i thought it was a very cool feature for a turbo timer...also calculates based on driving how long it will cool down for.

Honestly i think a Turbo timer on a 225 is a waste of time and incredibly inconvenient....
It's not needed, but if you're going for the gadget factor I suppose it's cool..

yeah well it was the first mod i did to the car before i knew we had a coolant after run pump on our cars....but since i have it i might as well hook it up all the way lol

My 01 AWP is wide band, and sadly my Defi A/F was narrow band :-(

They made the changeover on the mini-motors that year.....:-)

ack, ack!
