Thumbnail Filmstrip of 7.3L Powerstroke 94-03 High Current | Voltage IDM DTC HFHCIDM Images
The DTC HFHCIDM is a high-voltage, high-current injector driver module for a 1994.5–2003 7.3 Powerstroke. It is not a stock rebuild. Drive voltage goes from about 110 volts to 140, and current is up about 20 percent.
That opens the poppet faster and holds it more firmly, which is the usual upgrade on a tuned truck or one with bigger injectors. It uses the factory connectors. A P1298 soft code after install is normal on these modules and does not change how the truck runs. A core charge applies. The warranty is 3 years, unlimited miles.
It fits 1994.5–2003 7.3 trucks, OBS and Super Duty.
Fitment
- 1994.5–2003 Ford 7.3L Powerstroke
- 140-volt drive, about 20 percent more current
- Factory connectors
- Core charge applies
- 3-year warranty
A weak UVCH or a bad injector will still misfire. This module drives what is already in the engine. It does not fix a wiring harness.

I read you didn’t need high voltage if you run a chip in Powerstroke forum? I have a TS chip . I want to do full force 180/30 injectors with new solenoids and the full force chip reburn. Is high voltage ok with future upgrades

High Voltage IDM's are a good upgrade for all injectors.

It's not required or needed. Will help throttle response slightly however.

Don't know that I had an IDM issue before this. But I did notice after installing, my idle after start up was smoother and engine slightly quieter. I think I'm going to like it. Nicely sealed unit and built like a tank.

Great place to buy from. Truck has never ran this great idle smoother and throttle response is noticeably better.

If you need a IDM this is worth the small extra cost over a stock reman IDM. My 7.3 only has a straight thru 3.5” muffler and an air intake, not even a tuner yet… I instantly noticed a difference on start up! Throttle response is much more snappy and it’s easier to keep up with traffic now! Plus the purchase from a company that pioneered the HV IDM and actually tests them is a bonus! Don’t waste money on a stock reman.. the 7.3 should have came like this stock.

Bought this to replace my tired IDM. Very happy that it resolved the problem and outperforms the old one. Noticeable power increase and much touchier throttle! I would buy from this company again.
