Absolutely correct. This is the normal usage of the tweecer, the only suggestion I make is that you save (Write Changes) your changes to disk now and then so you do not have to re-edit your binary if you loose it or overwrite with a not so good tune.slowblown5.0 said:I have a question regarding the use of my tweecer. I have written the A3M bin file to my tweecer. Stop me if Im wrong--It seems like I can make adjustments to whatever I want---hit WRITE and then the tweecer is rewritten correct? Then I just plug that baby into the ecm and it will then run on that program correct?
I test each unit on an EEC and depending on which one I have on my test bench at the time, it could have any number of different binaries in the default position -- the othe 3 custom positions will be blank. Either way, if it does not match your processor family, the fuel pump will run continuously and the car will not run.
What would happen if you took a tweecer right out of the box and didnt write your stock bin to it and plugged it into the ecm?
Yes, that will work fine, you will be writing to the 1st custom position everytime until you get the switch.
The guy I bought the tweecer from spaced sending me the five position switch so I want to change my timing before that gets here. Is what I described above the correct way to do it?
