I got my ECU today. So the bracket is zip tied to another wiring harness below the two harnesses connected to the ECU so it isn't convenient to pull it out to remove the three 8mm screws on a bench. I highly recommend backing out the screws with your fingers so the lower one doesn't drop into the abyss.
So the fun part. It took about 10-12 miles for the Regen cycle to complete. I took the Jeep on a loop I normally take in my 997TT. A mixed of highway and a nice backroad curvy pass with good elevation change. I normally drive with Eco mode on so I kept it. Tip-in throttle is improved for sure. Around the pass the power band felt really good, the transmission didn't do anything funny, stayed silky smooth (had it reflashed with latest TCM update) and the truck ate up the runs up hill. In Sport mode throttle response improved some more so I like how Green Diesel Engineering set this up to offer varying driving modes.
The power? Green Diesel Engineering did a tremendous job of keeping the torque curve as linear as OEM. It feels like a bigger motor and 40-60 and 60-80 runs feel a lot faster. A ton of grunt and I was grinning the whole time.
Around town the motor makes about the same noise as before. Never aurally pleasing in my opinion but I'm glad it didn't worsen. The tune is docile and drives just like it did before except the noticeably better throttle tip in.
My hat off to the team at Green Diesel Engineering. For $850 it's a solid value proposition . This truck is fun now
