Hey guys, long time lurker here out of the shadows with his first post!
Some background: I am the owner of a 2018 GCC spec LC 200 with the 4.6 petrol engine and 6 speed automatic. I'd say about 50% of my driving is spent in the desert and I can't help but notice how sluggish the engine is going uphill on sand dunes. Whenever I floor it going uphill on sand dunes, it tends to up-shift unnecessarily and it loses all power and momentum, even with the shifter on S mode and traction control turned completely off. The up-shifts are driving me insane and I'm seriously considering selling the car because it simply can't keep up with the group during serious desert crossings.
Not sure if this is true, but the general consensus around here is that this is an issue with the 2015+ LC models, and previous year models did not have any issues with up shifting whatsoever. I drove my friend's 2014 LC 200 (6-cylinder, automatic) and the thing will hold second gear going uphill and redline until you let your foot off the gas.
Do you guys reckon an ECU tune will fix this issue? Perhaps a throttle adjuster like pedal commander?
I was reading through one of the older threads on here about how one of the user's was able to locate the ABS fuse and remove it for a better sand dune driving experience. I'll try testing this and see if it makes any difference and report back to you guys.
Let me know what you guys think. Is there a fix to this issue? Or are my dune bashing expectations too high for this car?
