I was about to name the title of this as “tuning a Mazda” but as mine currently sits being worked on by Track Tek I renamed the post to “running a Mazda…”.
This is going to be an ongoing piece to try and help others with getting their car up and running with an aftermarket ECU (in my case a Megasquirt PnP), and wideband AFR, (in my case Innovate LC-2).
I am going to try and list my “not to do, don’t skimp, you are better paying some money” list but can’t guarantee how quickly I will get this post done as it’s going to be a matter of starting from the beginning for me too.
Only until recently have I enlisted professional help in getting the car properly sorted. The initial build I did on my parent’s drive with the help of my Dad but it has gotten progressively more extreme to the point where I can’t use it as a daily driven vehicle. Hopefully when it is back up and working I’ll be able to work on it to the point I can drive it to work once a week at least 😉
Mantra – if it’s turbocharged, and modified, especially where it doesn’t come from the factory as such be prepared to spend some money!
