howell efi help

[markyyg]

Is any one running the howell efi system with a msd distributor, if so did u do anything different when u put it in. I put mine in and i don't think i'm getting a tach signal, are u using a tach adapter? any help would be great, thank you

do you have a working tach in your bronco now? you should be able to get your signal from the 6a box. when i ran the chevy tbi setup on my bronco i had a 6al box and a msd distributor. it worked good

I had a 6a box loose the tach output. Swapped boxes and the efi worked just fine. I'm not a big fan of MSD stuff because of things like that. I you are connected to the 6a box and do not have a signal suck it up and get a new box or swap in a different dizzy setup. I chased this problem for 2 weeks.

thanks guys, good info. I'm just running a msd ready to run dist and a blaster coil, no 6a box but I might have to check on installing that. thanks again for your input

The 6A should have a gray wire for the tach, I'm sure they're out there but I've never seen one without it.
