What it does
Adds ethanol-content and fuel-pressure gauges for a compatible installed GJP kit. It is passive monitoring: it does not add power or automatically provide a flex-fuel calibration.
Current file
The author posted the attached GJP Ethanol & FP Monitor 26.2 on August 28 after the original release and V2. V2 added voltage-to-PSI conversion for fuel pressure; use the later 26.2 file when following this post.
Requirements and checks
This thread is labeled for VA. The actual sensor kit and compatible wiring must already be installed. Confirm the displayed units and plausible sensor readings against the kit's documentation before relying on the gauges. The software attachment does not establish wiring, sensor calibration, or compatibility with other kits. The source thread includes the author's installation photos for reference.
