Good morning Dave,
I bought 3 spark packs off of you several months ago and installed them in my ford think along with your voltage spoof. My controller took a crap last week so I sent it to fsip to have it rebuilt and upgraded to 500 amps. After installing the controller I now get a code 16. Battery voltage is 92.4 volts at the batteries and pin 1 on the controller shows 86.6 volts. I have your voltage spoof installed but it seems it is only reducing voltage by 6 volts give or take. Looks to me like I need a new voltage spoof, let me know what you think.
Thanks Dave
