TCU options for a mid level type of experience

[ante]

Hi guys, first-time poster here. I’m living in Australia and I’m about to buy a 2019 Kia Stinger GT for $47,000 with around 40,000 km on it. I’m super excited — even though it’s a bit pricey, I fell in love with the car and I’m even getting a loan for it. I work in the mines, so I won’t be driving it often, which I’m a bit sad about, but that’s life.
I’ve been at work researching all the mods and, to my surprise, it seems I can modify the car quite cheaply with a massive horsepower-to-price return. I’ve seen that Burger Tuning offers a 450 whp kit for around $1,800 AUD, which I’ll probably buy.
The reason I’m here is to ask about the Lozic TCU tune options. I want to get the TCU tune eventually for better shifts in Sport Mode and stronger launches. I’ve done some research, but I’d really prefer an opinion from someone with actual experience. What are the best mid-level options for someone who wants good performance without causing too much wear and tear — and maybe be able to beat those annoying Mustangs I see everywhere?

The BMS kit is a great start, with intakes + plugs + tune (don't remember if it comes with the catch can, but that's worth doing at the same time).

My recommendation would be to work your way up incrementally, learning to read the logs as you try out Map 1 for a week or so, then Map 2. Then depending on your octane/ethanol availability and whether you're seeing corrections, try 3/4/5 as you get more confident.

Then reevaluate what you want out of the car. It might be firmer shifts, or more grip, stiffer suspension, etc. What I wouldn't do is buy the car and immediately jump to Map 4, aggressive TCU, and (say) lowering springs immediately, because that's a lot of variables at once, without having a well-balanced starting point.

Thanks for the info mate im more wondering about the options you have to pick when buying the Lozic TCU.

Post in thread 'Lozic ECU + TCU + AWD Tune'

Mar 12, 2025

Evening folks, hoping i came to the right place as I see this is a pretty active forum..I've had a Lozic TCU for a couple years and it was working great, I took my car in for some warranty work(oil feed tube) end of last year and put the car back to stock..Just recently last month or so I installed the TCU and I'm no longer able to build boost, 1-2 pounds any more than that it falls on it's face ..Stock ECU/Modded ECU same results, any ideas what could be the issue? Thanks in advance

Are you simply talking on the launch?

There’s a few threads on the forum specific to lozic. Lozic also has recommendations for a mild vs more aggressive tune regarding shift point % and shift pressure.

Check out that post. There’s alot of good info.
