Hello,
I?m trying to find a device that I can use with the Roush Data Tool. It says it needs a J2534 pass through device to flash the PCM with the Roush tune. My end goal is to back up the factory tune with the HP Tuner and transfer to computer. Use the pass through to flash the PCM, then back that up the PCM again and transfer to computer. So in the event something goes wrong I can put the factory tune on for warranty repair or updates, and then put the Roush tune back on.
Can I use the HP Tuner to be a J2534 pass-through device?
This would be on a 2017 F150 3.5 ecoboost
