Camcon VVTi Cam Timing Controller Thoughts? - Toyota Yaris Forums

I was able to install the wiring through a grommet so no drilling! It's definitely a little more aggressive in the mid range but i'm a bit on the rich side after 5000rpm, i'd rather play a bit conservative at first than run lean.

Overall the installation was not as frightening as I first thought!

^^ Sweet I just picked up a camcon about 2 weeks ago and im about to wire it up sunday if my Aem wideband gauge gets shipped in time . Can you please tell where the existing grommet in the firewall is and also help with the wiring . Thanks

No problem! I'll start working on a post and put it up tomorrow!

Ok so here is my short and simple install guide.

So you'll obviously need to disconnect the negative terminal on your battery before doing anything, don't want to get any nasty surprises!

Next- You should definitely memorize/refer back to this picture during installation.

The ECU we will be hijacking is located on the passenger side firewall under the hood, there will be a long and short connector. Go ahead and disconnect both as you will be doing the informational wiring on the long connector and the 12v source on the short.

I initially did some research on the Yaris repair book to get the correct existing ecu wire colors but once I actually started doing the splices I threw it out. The color codes are pretty ambiguous and as long as you double/triple check which wire goes to which port you should be fine, i.e. count from left to right, big or small.

On the above diagram all but the "cam" and "a/f" wires will be using the wire taps provided, these are a piece of cake and require no cutting. The "cam" and "a/f" wires do require you to cut them in order to intercept the signal and allow the camcon to do it's magic, you will use a male/female splice connector on these. The included instructions are pretty clear which color from the camcon harness goes to which wire. The following URL has the wiring schedule ---> http://www.powerenterpriseusa.net/pr...on-english.pdf (Page 10 of the PDF)

When all is said and done make sure to reconnect the ecu harness into the ecu and reconnect the negative cable to the terminal. Then proceed to follow the camcon instructions on proper starting procedures to make sure everything is up and running.

I routed the actual camcon harness wire through a bung located in the passenger footwell, under the carpet. You can just pull the plug out and run the harness along the firewall, taking care to keep it away from the exhaust manifold (mine is roughly 5-6 inches from the manifold). I installed it right next to the cigarette/power adapter on the bottom of the center console to make sure it was out of sight at night and still be accessible.

The following is the chart I followed in programming the cam angle/ a/f values and will be fine tuning.

Honestly it was not too terrible to install and this was my first time splicing a wire in my life. I would certainly recommend researching splicing techniques prior to installing.

Good luck to any fellow YW members who decide on attempting this!

Are you going to tune it or just use those numbers?
