I have a built low compression y7block with z6 head.. i am throwing a code 14 but i am getting 12 volts at the iacv plug.. so i might need to change my iacv or maybe get a new ecu but i dont think its the ecu cuz i got it from xenocron..unless its from hooking up the wrong sensors.. i gapped my plugs at .045 and i used a y8 basemap with scaled injectors to 320 even tho i have 440s i just want to make sure its running rich.. but my wideband keeps going lean right away and stays lean all the time.. i checked the plugs and they are white.. anyone tell me what basemap i should use or what i should do. thnx. if someone helps me get the car to run rich or figure out why it keeps running lean i will paypal $10.

try your batter offsets int options menu not for the injectors though the one were you select what injectors you have and turn the numbers up a little.

nvm its my o2 sensor.. i have a plx 250 hooked up to the + and - on the chipped ecu.. i have o2 disabled.. however the o2 plx device goes from 14.7 to lean after about 10 seconds.. im not running lean cuz i used a different map and looked at my spark plugs which were kinda black from running rich.. should i go buy a bosch wideband o2 for a vw and hook it up to my plx or replace the whole unit?? and i also read that i need atleast 3amps of current for the wideband.. will it get enough voltage out the ecu's + o2 wire?? thnx

hook your wideband up to a good batt source

just did at the radio.. i checked with multimeter.

its running rich now i can smell it...

ok so i bought a new bosch o2 sensor and rerouted the wiring to the radios ground and positive... still the same thing.. however wen i wiggle the plug that plugs in the display to the o2 sensor it changes a bunch like it will go to 10 afr then go to rich and sometimes lean or free air... etc should i cut this plug off and solder all the wires together?? or just ---- it and save up for a new wideband system

look under your dash at he fuse box a black with yellow stripe use it. your radio will pull power that is the wire that sends power to you fuse box to be distributed. i use the aem wideband and my af were off b/c my radio pulled to much power away from the sensor unless your wideband has been hacked by my car smells fumey at lean afr when its rich its more smokey

i dont even have the radio hooked up.. im using it just for the wideband... so the ground and positive are good.. it powers up and it has a new o2 sensor..
