XTREME -> Need assistance with Turbo Timer (4/4/2006 4:55:17 PM)

I purchased an Apexi Turbo Timer and while going over the instructions I received I was unable to figure out all the O2 sensor and A/F ratio stuff. I do know how an O2 sensor works (closed loop, open loop..etc) but I'm not sure what setting the O2 voltage should be at for my Evo. Does anybody have any advice?[8|] Here is an online version of the instructions:

I haven't hooked up the Turbo Timer yet so maybe I'll discover something while playing with the buttons.

well it gives you a table pertaining to the settings for the a/f ratio and what the o2 sensor voltage is in comparision. For your car it looks like around 950V for the o2 sensor. Or try and set the a/f ratio to around 11. But i have never used one of those before so i dont know how to use it. Or how well it actually works to tune the a/f ratio. But you would be looking for around 11.0-11.3 a/f ratio.

Can you tell me where you got your information from?

I was able to get the ECU pin chart for the Evo IX to finish installing my Apexi Turbo Timer. The ECU connections for the Evo IX are very different than the connections for the Evo VIII. If anybody needs it let me know.

oh wow i never saw the post of you asking me where i got the info. Honestly i now dont even remember where i got it

That's okay. My brother installed his Turbo Timer on his Evo 8 and we were able to get the A/F set correctly which is 14.7 after the engine switches to open loop. Once we figured it out installing it on my Evo 9 was a piece of cake.

My turbo timer is a bit easier to install I guess. Its simply a hornet security system with a built in turbo timer. It works great and does exactly what I want it to do.
