Lozic ECU + TCU + AWD Tune

[Avon]

Did you try your stock ECU again and see if the sputtering still occurs?

I had like 3 ECUs from lozic at one point because had no problem with stock ECU. I changed spark plugs and problem went away so we then knew it wasn't lozic tune. Problem is the sputtering came back after few thousand miles. So would take out plugs clean them up and problem would go away for few hundred miles and return. Finally did what lozic recommended and got new coils. Since no problems at all. Been several thousand miles now and still purring.

Btw lozic was awesome whole time. It was a big expense for both of us to send all those ECUs across the earth.

Yep! No issues with the stock ecu.

 

[HoosierStinger]

Yep! No issues with the stock ecu.

The electrical load on the coils may not be as high for the stock ecu as it is for Lozic's tune. Maybe you can ask Lozic if he can get you a good deal on OEM coils. I heard he can supply OEM parts now.

How much are coil packs for the stinger? Lozic recommended I change my coils aswell since my Stinger has 110,000km.

Im in the semi same boat, as of today, I will have 3 Lozic ECU's and my OEM ECU at the same time. Granted, at least two of them are going to be sent back soon, but my most recent revision is out for delivery today.

Not sure if this was posted already, but Lozic has their own EVC Catback exhaust now. H-Pipe instead of the tradition X-Pipe gives it a much different tone.

I just bought an oem set off of Albert Hwang (Facebook) for $355 shipped from Korea. It takes about a week or so to get here. He’s an oem parts dealer who lives in Korea and very easy to work with.

So purely based on that link above, about $50 in savings going through him. If shipping times are roughly the same then why not save some money!

Hey everyone- just an update. I received my revised tune yesterday. I have only drove in comfort mode so far. (Power by mode option D-so 1.2 bar) The comfort mode is running strong. No big timing corrections etc. To me it feels a touch slower than map2. My map2 peaked at 20 and this 1.2bar peaks at 19. But overall about the same power. I’ll be doing sport mode 1.4 bar later today. I definitely like boost ready not always on. Always on was too much for me. This one is set at above 3k rpm- feels great. Also the cruise control not showing the speed you are set at is still a problem. When I set cruise it just shows - - - (but cruise works) so it’s not a huge deal. I’ll keep you posted after I try sport mode.

My car is in the shop for a front collision with a deer. The repair shop had to take it to kia to recalibrate the front radar senor. Will that affect my lozic ecu tune?

At Concept 3 Performance website, they have 6-HKS M45il with 6 OEM Coil Packs for $331.33 plus Shipping & Taxes make it roughly just under $400. Decent price and they are here in the USA

Alright everyone.. opinions/help needed. I just did my first few pulls in Sport mode (supposed to be 1.4bar)- maybe I need to let the ECU learn more? But the peak boost in comfort mode is actually higher than the peak boost in sport mode? That was the issue with the last tune as well. I thought it was because it was an incorrect tune etc.But there now has got to ge a reason for this right??? Also this tune has the same throttle readings.. meaning comfort mode it rarely makes it to 99. But in sport mode it makes it to 99 just fine. So my guess is this has something to do with power by mod and how it’s controlled. Regardless I thought I would feel a nice difference in sport and honestly I didn’t.. I could do some draggys to be sure? Or maybe be more patient? Also today was the hottest day of the year here as well. All thoughts and opinions would be wonderful. TIA

Forgot to add timing is wonderful with this tune though.

so 1.4 bar is just over 20lbs of boost. I assume you are logging with a JB4 to see peak boost? also to confirm timing is not being retarded?

with the stock ECU, the "comfort" setting basically changed transmission logic, IE quicker shifting to higher gears, as well as reduce throttle response, lighter steering, softer damping, etc. With this Lozic tune, was he also looking to reduce boost in Comfort, vs sport, vs smart, vs. eco, etc.?

Logically I would think if you floor it in any mode, you should get max throttle, max boost, etc., right?

Also, does it even matter what peak boost is in comfort mode? you wouldn't be driving it all out anyway, and with RPM's not building as high based on the transmission shifting sooner, you won't get to peak boost anyway, right?

Also, JB4 map 2 typically peaked around 18/19 lbs of boost, which is really the limit of 93 octane. If you are running good 93 octane, then you are at the limit as far as timing goes.

Yes I log with JB4. All modes except sport are 1.2 bar. Sport mode is 1.4 bar. Peak is basically the same in both 19ish. (Actually a touch higher in Comfort) My TCU tune shifts close to the same rpm in all modes. The throttle thing just has me confused- even though it says less than 99 the car feels in go mode. Side note I would peak at 20 in map2 when just on Jb4.

I'd say since you have jb4 if you want more boost and you have the octane to do it just add a few lbs via map 6.

Not a bad plan. Just thought the tune would of already accomplished that.

For me the lozic tune was more about additional timing advance the stock ECU would allow. If you have jb4 and lozic tune you can push limits of timing, boost, fuel and octane.

Here is the response from Lozic so far- in case any of you are curious.

Let's check more about the cruise control mph indication.

You are right that the Boost Gauge is higher in eco comfort.

The boost and power of ECO comfort are not made by direct setting, but you can think of it as a method of forcibly limiting the maximum power of Sport.

And since the boost gauge is a sensor mounted on the outside of the throttle, it is displayed higher because of the throttle limit.

The boost pressure of the actual manifold is lower.
