I just wanted to help out anyone that might be wanting to install a turbo timer on a 2010 Mazdaspeed 3. I did a lot of research and eventually found out that the ignition wiring harness on the 2010 model is significantly different. I did find the correct wiring diagram for the 2010 and proceeded to wire my TT in properly. The car locks properly using the keyfob. Only issue I had is with the RPM mode. It adds time way too fast
Wiring Unit/Car
Red/Orange - 12V Const
Blue/Pink - Acc1
Green/Blue - Ignition
Black/Ground - used bolt behind the throttle pedal
Brown/Purple - handbrake
Purple/Orange - Speed Sensor, I used the wire in the radio harness
The method of accessing the ignition harness is the same as the previous gen. The only difference was the wire colors. If anyone has any questions, I'll be happy to help out
I'll try to post some pics later
EDIT: I forgot to mention that i have the non-tech version. Also, I've been experiencing a CEL with code p0606, ECM processor failure, every once in a while. It causes the car to go into limp mode. The only way i can get it out of limp mode is by disconnecting the negative terminal on the battery for a few seconds, just long enough to reset the processor but not lose all of the settings on the car. If anyone can offer any advice on how to remedy this, it would be awesome.
EDIT2:The limp mode happens very rarely for me now a days, I think I've pinned it down to leaving it in accessory mode after shutting the car down or putting it in accessory mode for an extended period of time with out starting the engine.
