Question/Prob after installing Apexi Auto TT
Yea, well its more like a feature isnt working..... Ok, what I have is a '03 WRX and mods on my car are the MRT Turbo-Back and silencer removal. I installed the Apexi TT last night and almost everything works... It counts down just fine, voltage meter works fine and my o2 voltage sensor works.... The problem is that my A/F doesn't show up. When I start the car the 1st time, all I see are lines where A/F should be. If I started it again within the next 5-10 minutes, I get numbers (basically 10).... Now, IF the car is OFF, it shows A/F of 15. While I am driving its at 10 all the time. Doesnt matter if I floor it or drive casual... The ONLY time the A/F fluctuates is when I am idling at a stop. It will go from 10 to 10.2 to 11.2 and back down to 10. What I spliced into the ECU is as follows:
Looking at the ECU, I pulled out the 2nd plug from the right, connected the TT's WHITE wire to the 2nd WHITE wire from the right of the plug, and connected the TT's BLACK wire to the Red/Green wire on the FAR LEFT of the plug. Now I do not get it, I get an o2 sensor voltage reading but no A/F reading. Did I connect something wrong or did I not adjust any of the Apexi TT functions correctly? Please help me out asap! I thank you all in advance... ~John

apexi tt
I don't think there is a problem with your timer.
Mine dose the same thing some times. After driving (not just idling, it must have load I.e. normal daily driving) the car for a few minutes the timer will display the a/f ratio. It needs to be able to establish a baseline because all of itls readings are derived from the o2 sensor. hope that helps. |
