Shifting pattern: when (on what RPM) the gear changes/upshifts .. so if stock TCU shifts at 6750 rpm automatically, the tuned TCU will automatically upshift at lower RPM (5% or 8% sooner/earlier than 6750RPM) , which results in more power/ better accelerationIs there a good explanation anywhere on the Lozic TCU options? I want to learn more about what the shifting pattern, shifting pressure, and "more powerful sport shift pattern" actually means. For those with one, what options are you guys choosing?
Shift/Line pressure: how strong/fast the shifting happens (results in less boost drop between gears) results in faster acceleration but less comfort on full throttle
More powerful sport shift pattern: means how the sport mode behaves with shifting in general (upshifting and downshifting) .. here Lozic can switch your regular sport mode with the new sport plus mode (like in the Genesis G70 2022), which holds gears much longer and the revs stay higher on moderate throttle and the car downshifts earlier to always stay in high RPMs to be ready for you when you step on it
This is very useful on track days if you don’t want to manually shift gears or want to have more fun with the car in general.
Just note that adding sport plus will replace your regular sport mode and on full throttle there shouldn’t be a difference in power just better throttle and boost response when you first step on the gas pedal because the RPM is high.
Torque limit Off: choosing torque limit OFF will remove launch control and the car will build much more boost on Launch if you want it to and will also do burnouts (can be useful for AWD cars with very good Tyres and for record chasers)
I don’t recommend it for RWD, as you will likely still be having traction issues while launching even with torque limit ON
Note that your car will still build boost on launch even with torque limit ON, it’s enough for RWD
Auto upshift when manually shifting: here you should be careful, if you choose “Yes” (even though it says “like stock”) the car will ALWAYS upshift automatically if it hits the the maximum RPM -5% or -8% .. you can never hold gears yourself (drifters take note as the car will upshift mid drift if hits max RPM)
On a stock TCU the car will automatically upshift unless you put it in sport and turn off traction and stability control off (so you have the choice)
But with the lozic TCU if you choose “YES” it’ll always upshift automatically even in sport mode with stability controll OFF.
And if you choose “NO” the car will hold gears for a long time and not auto upshift until you pull the upshift paddle (talking about manual mode of course) there’s is still a safety limit where it upshift eventually but it’s much longer than stock.
I have talked with lozic about it and he said he could program it to whatever you like if you told him specifically to, that’s why am explaining it here in detail for you so you know what to write in your order sheet.
He might add the option in the order sheet to make the auto upshifting by choice like the stock TCU (by turning ON/OFF stability control in sport mode for those drift events)
I personally went with (shifting pattern 5%, line pressure 2, torque limit ON, auto upshift, regular sport mode and no sport plus)
