Zeitronix wideband in and Tuned
To start i wanted to make a special thanks to Joe, 98blackmax for all the help. I mean a lot of help from this awesome fella.
I purchased a used wideband (bad idea) turned out that the data cable that connects the sensor to the unit was f'ed up so it was not working. And the time this all happened i thought that the sensor was bad and left the cable in because Joe did an awesome job rigging the cable in that it looked clean and stock . I used the new Zeitronix with the new sensor with the old cable not knowing that the cable was bad and tuned my car to bad AFR
.
After a day of trying to tune the car it just did not feel right I figured in between class to jack my car up in a school parking lot change out the cables and see if that makes a difference and SOB it did. Anyway long story short the car is tuned from 2800rpms at about 13.8 till 6500 at about 13.5. I tried to straighten the AFR from 13.1~13.6 all the way to redline. And BTW for anyone thinking to go WB buy new and please get the one that datalogs. Its so much easier to work with.

I made the most power on the dyno from 13.0 to 13.1 when I was N/A and it varies from car to car, but IMO 13.8 is too lean and actually makes less power. Thats where my car was when I started and I picked up around 5hp through the entire curve by adding fuel.
