No obd. It is a FASTEZEFI multiport system. I got sidetracked on some other projects and haven't done anything on it yet. I just set her rev limiter to 6500.
I hope you are right. I know the EZEFI is sensitive to electronic noise. I was hoping some one on here had already one this. When I find out for sure I will post.
I put a stroked 5.7 in my wife's satellite [sorry,not an a body]. I used the tach signal from the MSD Hemi6 to trigger the FAST EZEFI. How do I hook up the tach? Can I trigger it from the same wire without affecting the efi?
