This AFC controller that I am working on will allow you to dial in the maximum fuel allowed and the duration of time that it takes to reach the max fuel setting. There are two knobs, one sets max rack travel by limiting the afc's travel distance, the other knob dials in how long it takes for the rack to travel to the desired distance(a mechanical fuel map). this kit is a Semi DIY kit as it will require plumbing the lines and mounting the two valves. the kit will come with everything needed materials wise. All that is needed are some basic tools.
The knobs can be remote mounted in any location for a very clean and desecrate look. The other option is a mounting plate that I make that will delete the factory cup holder that slides out of the dash. This plate bolts right in and allows for a very clean install that requires no drilling. If your cup holder mounting tabs are broken let me know and I can send a plate that does not have the holes drilled so it can be cleanly epoxied into place instead. This plate only fits 94-97 trucks with the earlier dash and dash bezel. the dash and dash bezel were changed in 98 and the mounting plate is still in the works for those trucks, the 98 12v's and any p pump converted 24v engines.
There will be a option to add a MAX fuel switch which will bypass both valves and allow the pump to achieve max rack travel rapidly.
The last photo is of the remote mount setup. It can be mounted anywhere on the dash, the best place I have found is the lower kick panel on the right hand side of the steering wheel as pictured. It does have both adjustments as well, the fuel map adjustment is just to the right and back behind the plate. It is easy to reach without having to lean foreword so your attention stays on the road.
Another benefit to this system is being able to shut off boost to the afc easily netting a nice mpg increase when the power is not needed. Also being able to control max fuel available will allow you to have much more control over your egt's and allow more extreme fueling mods while still keeping the truck very use-able. if you have any questions or inquiries please message me as these currently will be a assembled when ordered part so i can custom tailor them to your application.
