If you’ve ever had to manually copy injector data from an Excel sheet into HP Tuners, you know how repetitive it can get. I made the GM Injector Template Generator to make that process quicker, easier, and less prone to copy/paste mistakes.
The program takes supported injector data sheets and creates an HP Tuners .htt template for several common GM ECUs, including E38, E67, P01, and P59. It can also handle automatic injector scaling, fixed or vacuum-referenced fuel pressure setups, and fuel composition options where applicable.
Current injector data support includes:
- Fuel Injector Connection
- Injector Dynamics
- DeatschWerks
- Fuel Injector Clinic
- MRP (Added Sept 10, 2026)
The goal is simple: save time and make injector setup in HP Tuners easier.
Because injector manufacturers sometimes change their spreadsheet layouts, always compare the generated template against the original injector data before flashing a vehicle.
If you have injector spreadsheet data from a brand that is not currently supported and would like us to add it, email us at support@horsepowerfactorytx.com.
