Lozic ECU + TCU + AWD Tune

[Williamsj41]

It would be nice to see why the log I posted earlier today with the 1420 time stamp. See what in the tune caused it to go from the 1.5 bar tune boost level for 3 pulls down to factory boost level on the last pull. I can't see anything that would cause that on the log.

@sweetboyed - Can you review post #385 logs and answer williamsj41's question.

@xot1 - Would you mind helping translate from Korean to English and with the technical details?

Thanks. I am suppose to get the new tcu tune in tomorrow. I am going to see if it shifting me at 5600 - 5700 rpm and shifting faster it might actually clean the timing and stuff up I do hope. He did tell me the power peak for the tune needs to shift at 5600- 5700 at WOT. I do know when I started paddle shifting trying to get around those points most times it did behave better. I hope it also helps my awd tune also.

Do you mean here?

I would like some clarification about the possible fuel differences and if we do actually need to be running a higher octane

 

[Team Tonka]

Could someone with Lozic tune clarify how the launch control changes with just the ECU tune?

How does the launch control work with the Launch Control Torque Limit OFF for their TCU tune? Does one basically use it just like the OEM launch control I’d – but it will build more boost/rpm since it’s not limited to 2300 RPM? If so, why not just set the RPM a little higher to say 3000 RPM vs. having it OFF?

Launch setting at 3000rpm is not possible.
This is related to the amount of slip of the torque converter.
Since the launch torque limit is turned off in Lozic TCU, when raising the torque converter slip above 2300rpm, the rear wheel slips and raises it above 2300rpm.

If you write it in the order form, it will be reflected in the setting.

 

[sweetboyed]

I defentally agree with you slip angle on that. I run into the language barrier with him as well.

Haha.. I know it too.
That's enough to make it easier to understand by running Google Translate several times.

This is the one I have says it's for a g90.View attachment 58987

Why did I use G90 ECU?

It is difficult to obtain parts.

So, ㅑ purchase ECU TCU AWDs from other vehicles that use the same model ECU and change the data to fit the vehicle type.

simply the part number is different.

G90 ECU is more expensive. hhhh

 

[sweetboyed]

My stock ECU was labeled Hyundai, as was the one I received from Lozic. They were different part numbers though.

Why are ECU part numbers different?

Same for AWD models I'd assume - rear wheel slips above 2300 RPM?

So I'm assuming those that get the ECU and TCU tunes are leaving the launch control torque limit to "OFF"?

Yes, this is a faster way to start.
When the brake is released, the torque of the rear wheel slip is transferred to the front.
If you release the brakes at too high an rpm, all 4 wheels can slip.
If so, would it be slower?

I might not be saying this correctly as well but, is 93 octane in the USA going to run the same as having 93 AKI settings on the tune. It seems people are having to increase their octane rating with either methanol, E-blends and race fuels to lower timing corrections. Maybe someone else can say it better than me

93aki is 93octane (at least how its measured in the US is my understanding). I think someone else mentioned it, but Korea might have 100 RON more readily available which is 95octane. And in the US our 93octance generally can have up to 10% ethanol in it, where in Korea they won't. Could that be the reason some are getting timing corrections - I don't know.

 

[Slip_Angle]

It's also important to note that a low level of knock based timing correction at times is normal, provided it's not too much.

If you need a remap, we can do it for you. It just takes time for delivery.
There was no need to modify the ignition time except for the current specific area.
High octane fuel in Korea averages RON 97.
Between 95 and 100 RON.
Regular fuel is RON 91~93. There are also settings tailored to regular fuel. It goes up about 55ps.
RON91 is AKI 87.
You don't have to worry too much about ignition timing. It was set up after going through many harsh tests.
Send me a log file or if there is a section where there is a knocking sound, I will solve it.

Hey everyone just tested the Lozic TCU tune with my JB4. Very happy with it, but need to play around some more. My 0-60 was 4.13 (3.88 1 FT) (That will get better) used launch control. Best ever before this was 4.41.

I spun all wheels today.

 

[Team Tonka]

For those with the ECU tune, I already have a valvetronic cat back exhaust system in my 2019 G70 3.3T (see link below). It already has a little bubble and pop when downshifting, so I’m assuming if I had you add BUBBLE to the ECU tune it might actually make it a bit louder? I would only do it under around 3000-3500RPM, but if it the BUBBLE makes it a bit louder I likely wouldn't do it. Thoughts??
