Lozic ECU + TCU + AWD Tune

[G70LEbyAdoom]

Currently the Denso (1 Step Colder) that was recommended by BMS gapped at 0.022. Ordered the HKS m45il and Lozic said not to gap those.

Good. I was going to suggest the same thing.

I appreciate you taking a look. This community is fantastic!

Oh also I live at 4,500ft elevation. Which may have an impact?

Setting catalyst heating to 'Off' should make your cold starts much quieter, not louder. The factory ECU wants to heat the catalytic converters up as quickly as it can when they're cold, as they work much more efficiently when they're hot. To do this, it dumps fuel into the engine with a richer A/F ratio, and idles the engine at a higher RPM to stop stalling. This is why cold starts are normally so damn loud. If you have this option off, the ECU won't try to quickly heat up the cats, so the engine will sound like it does after a warm engine start (that is, much quieter). If your car still has its converters you should probably keep this on, but if you removed the cats then turning this off will make your morning starts much more tolerable for the houses around you.

Yup Lozic replied to me. He confirmed that if I choose OFF for catalyst heating the cold start will be quieter. I'll keep it ON. When I originally ordered my ECU I chose ON for catalyst heating. Now I'm ordering a remap due to performance modifications. But I have observed that even with it ON the factory ECU seems to have a louder cold start. Has other observed this? And thanks for the detailed explanation.

that could be, because the air is thinner. I don't think that it would be the cause of the sudden timing variations though, as those would be there from the start if that where the case.

the boost ready feature also keeps the cold starts quieter from what lozic has told me. so if you got boost ready enabled, that's why.

I ordered same 1.4 as you!

Ahh and the picture becomes clearer. I do have boost ready ON. That would be a logical explanation. Thanks!

I guess more exhaust passing over the turbine reduces exhsust dB

That's the exact reason he gave me, though the way he worded it was more technical haha

Real quick- does anyone notice their TCU shifts out of 1st gear around 200rpms (ish) higher than all other gears? Example shifts out of 1st at 6,000 and all other gears shift 5,800.

So, random question. I have the 1.5 bar and it’s been showing up to 24 psi, which Lozic said should be available below 4,000 rpm. I’m a very new car guy (I don’t know crap), and I had this shower thought/question. Stock boost usually was 12-14 psi, and I know some people have had issues with their turbo blades looking like garbage (stock). I have also heard that the stock internals are trash as well. So my question is, would doubling the amount of boost on stock turbos have long term damage? Probs a dumb question but I am learning a ton just reading random threads in this community. Thanks y’all

Considering how many people in FB groups claimed OCC is scam and intakes are just for the sound while slapping a JB4 on and running 22+ psi with stock filter, I’m not surprised that many failure posts. Stinger owner community is really weird and fully loaded with misinformations.

Remind me when you launch are you leaving it at the 80/20 split? Or moving to 50/50? Pros and cons?

I didn’t know it would adjust if better octane for more power. I love that! I only have 91 but can sometimes add some E85. So that will be good. I just sent my order form today. Slip didn’t you have an exact tune made for you? And to clarify the 3.69 was the standard 1.3 Lozic tune?

I'm not sure I follow your question on the split. Can you elaborate?

My bad! When you launch are you always just full sport mode so 80% power to the rear wheels and up to 20% power to the front wheels…or do you do what some others do and put it to the custom mode— everything sport except the AWD setting is set to comfort. So then the power is 50% to rear wheels and up to 50% front wheels? Hopefully that makes sense on what I am asking.

Sport mode
Stability and Traction off
Floor it and send it to Jesus

Love it! Have you ever tried the other way? I’m very curious if it helps 60ft times or not. I’ll have to experiment.

The stock internals are forged. they are extremely overbuilt from the factory considering the 365hp the motor is rated for. Kia/Hyundai knew that people where going to mod this motor. Now its not built for 1k horsepower or anything like that, but there are 500whp daily drivers out there doing just fine for the most part, and when they do fail, 99% of the time its the head-gaskets, which are a pretty common failing point in all turbo cars, especially subaru's.

If by other way, you mean custom mode with the 50/50, then no I have not. I might if I remember at the strip next time.

I thought I read about our cars having forged internals but can't find it anymore. Where did you view the information? It would be great information for everyone I think.

Yup! He's just the nicest guy and bends over backward to make sure his customers are happy.

He's offered to send us KDM Kia parts for the best prices too. I saved so much doing business with him!
