I am preparing for a turbo swap so i ran the lines for my DD, pyro, and boost gauge thru my dash. i figured since they were there why not hook them up to somthing. I connected my DD to the key on wire under the dash for power, the head for a ground and the harness side of the black wire on the o2. now where it gets wierd is the readings. remember, this is a n/a car
idle - usually flashing red every couple secs
under WOT accell - flashing red
decel - solid blue then drops down
WOT - climbs up to blue slowly

should i be rich enough to see full blue??

engine mods:
4 TBto manifold gaskets
gutted airbox/cai
K&N dropin
ozone generator
2" cat back exhaust
bosch +2 platinums
less than a year old mopar o2
cam timing dead on ign timing 16*

thank you

is this the beauty of "tuned for emmissions, not performance or fuel economy"?

Move the ground to the negative battery terminal, you might get some weird readings since it has to travel through the cyl head to a ground wire before reaching the battery. At idle and cruise, the red LED might flicker once in a while- but under WOT, it should light up the green or blue LED.

If your in doubt, backprobe the O2 signal wire with a multimeter and go for a ride. The voltages for what LED turns on should be on the 3bar Racing website.

im more wondering what is going on in my engine....I believe what the DD says is right or at least close. I'm wondering if its normal for me to go that rich? and if my TB spacers are adding to the difference....i duno....maybe it just the way the cal is tuned

most cars will go rich at WOT

i just got an idea from some spam on ebay.......could i hook up a potentiometer in parallel with the coolant temperature sensor so i can have it normall turned off and it will work normal but then when i want to go WOT i turn it till i find out when i get the best A/F? or is there some other way to lower the fuel delivery?
