ok I need help, I am trying to make it out this weekend.

I have a S300 hondata, I can not datalog while I am using a my msd(digital 7 and HVC coil), as soon as I put the igntion all stock, I can datalog, I know the easy way would be run it stock, but what the hell, I know it is possible to run..
thank you
anybody
seth

 

anybody, what the hell is goin on..

 

It's probably RF noise causing the problem. Twist the power and ground wires into the MSD box, as well as the wires going to the coil. Also make sure to run them away from the main harness, and if they do cross any signal wires on the main harness, make sure they cross perpendicular and not run parallel to the harness. RF noise can make really weird things happen! lol

 

yeah well now I have the coil rapped up in rubber, lol, it is dataloging now, but when I try to adjust anything on the hondata, I get no response, like its not conected..
