🦅 2018 Jeep Grand Cherokee Trackhawk, 6.2 L, V8 🦅
One not so ordinary Trackhawk with a lot of unknown aftermarket parts, that has been revived and returned to dominate the streets after many faulty diagnosis and auto mechanics.
The vehicle came with CEL and DTC "System too rich" and it was going into limp mode on WOT. The customer has bought new bcm, new PCM and T-case due to wrong diagnosis. 8 hours, one fuel tank and about 100 files later, the vehicle was back in full health and ready to dominate the streets. Software was showing about 900 hp. The vehicle has smaller pulley and bigger injectors (at least that's what we saw).
A lof of people will be like "a whole fuel tank, 8 hours and 100 files??", this is because of the "Artificial Neural Network" and we wanted to do it the proper way, not by hacking it. We needed to go through all of 25 maps in the ANN and modify them.
We have changed the thermostat as well, with a Mishimoto one that opens at 82º and tuned the system for it.
📍 Thermostat Mishimoto
📍 Unlocked the PCM.
📍 Unlocked the OEM OBD port for aftermarket diagnostics.
📍 Tuned the fuel map with ANN for smaller pulley and bigger injectors.
📍 Tuned the cooling fans for 82º C thermostat.
