Broken Quarterhorse or Something Else?
Posted: 2023 Mar 20, 22:21
I recently installed a quarterhorse in my car and have been fighting with it so far. It’s left me wondering if my device is broken or too old and suffering from software compatibility. It’s an earlier quarterhorse without a battery socket. I bought it used and had to solder in a new battery. Binary Editor shows the device to be version 1.6 and displays serial number 0. Initially I set the quarterhorse to basic mode, cleared its ram, and loaded up the base t4m0 calibration. It did not idle well and after a short period of time just wanted to fall flat and stall out. This is not normal, my car has run surprisingly well on the stock computer with the calibrated maf and always started fine. After trying a few different things, I eventually thought to try other quarterhorse modes in Binary Editor’s hardware settings. I manually changed it to advanced settings, mode 2 and tune 2 (where it automatically loaded to when in basic mode). After this, the car started fine as it always had and ran like normal. I figured on my first attempts it was trying to run on blank tunes. A few days later I load in my first real base tune with the idle adjusted, maf transfer, and injectors parameters. It ran like crap again, was extremely rich, and was flooding the engine, and wanted to stall just like my original experience after the install. So I let it sit for a day and reverted back to a plain t4m0 calibration. Same results, tried a different tune number, same results, wrote the tune to all 8 banks, same results. Now I’m feeling the need to remove the quarterhorse and go back to running the stock computer for now. Maybe change over to a newer ecu system. Any thoughts on my experience with this?
