just need a new baseline to tune from

MTF as in Mass Air Transfer Function?
Or do you need a base tune in MTF format?


The Mass Air doesn't change until you change injectors.

Here is a base file for ECU Code JFA7 --> https://drive.google.com/file/d/0B4sorV ... sp=sharing
Here is a base file for ECU Code ZYF5 --> https://drive.google.com/file/d/0B4sorV ... sp=sharing


I'm not sure if either will work for you though, and any risk is up to you and you alone.

Thanks yes I was looking for a Mako Tune File, I will look through and see what I can learn.

Car acting weird or what?

If you shoot me the tune file and a log I might be able to offer some help.
