Lozic ECU + TCU + AWD Tune

Nice. What shift points?

Not sure what you're asking...

Not sure what you're asking...

@ what rpm do you change gears?

 

[BadTrainDriver]

@ what rpm do you change gears?

Whatever it does automatically. 6k or so.

 

[BadTrainDriver]

Speaking of shifting gears, I was a bit disappointed to lose rev match downshift. Did you guys lose this as well?

Stock doesn’t have rev match

The rev-matched manual downshifts are appropriately quick and smooth."

Mine had it...I used it all the time during spirited driving.

I emailed Lozic about folks that were seeing timing corrections: "I’m hearing from folks in the USA that have the ECU tune for the G70 or Stinger 3.3T that they are noticing a lot of timing corrections. Any thoughts on this and what would be the best tune to get from Lozic so it’s a safe tune on 93 octane USA fuel?"

Below is their response:

"No need to worry.

You don't even have to worry about ignition timing.

93 octane is safe.

We also have tune data for 89 octanes.

It hasn't been a problem since I did a lot of testing."




It seems they are confident in their canned tunes.

I can't wait until we have something like a Cobb tuner, so we don't have to send out the spare ecu's.

I don't think cobb is going to enter the kdm world. They didn't touch the genesis or veloster I don't see them taking the stinger

Yeah, that's what I heard as well. That's why I said "like a Cobb tuner". Just something that we can pull data from and upload new maps to.

I think we finally found the right fuel octane for the stinger and lozic tune on the aki 91 octane. It ended up being ms109 mix with 93 no ethanol. Should have been around 97 octane (r+m)/2. Makes me wonder if his aki 89 octane would work fine on the 93 octane here. The first couple short pulls the fuel was still mixing coming through the lines.

I think 93 with meth should work as well

97 AKI? Wow. For those of us with 91-octane-max, using a very simple octane-averaging calculation (not sure if I'm doing it right), and using pure ethanol as 113 octane, and a minimum E85 pump value of 70% yields 104 octane for that E85 @0.7, which would require > E45 mix (with 91 octane) to get 97 octane. If you get actual E85 (which is rare), you'd still need close to E35. Just to run "ok"? That's pushing the limits of the stock fuel system, and it doesn't let you use CPI, which can, in theory, run up to E50.

Any more comments about the TCU / AWD modules (from anyone)? I'm more interested in those + jb4..

 

[Williamsj41]

Well I will say redchromo on here uses meth and 93 even tried 100% VP M1 and his timings are still out with that mix in the stinger. And yes I have been working with Terry and I do have cpi so I have tried up to E50 and yes the octane is definitely there. But since Korea doesn't have Ethenol Terry thinks it's their fuel scaler that is not set right for the E so timings are still bad.

 

[Williamsj41]

I have alot had this tune with the cpi and heavy E mixtures act like the tork tune. where if I start getting much under half a tank it starts acting pretty bad seems to be fuel pickup issues and the lower it gets the worse it is. I would assume since the cpi is sucking fuel before it even gets to the hpfp. Added with the need for more fuel on the E mixture side. I will say I used the exact same fuel and switched to the oem ecu at e50 ran it down to 15 miles left in the tank without a single issue. It was trial and error and I know the other stinger running meth does not have that problem. At this point I will probably switch to meth and just use this as a drag strip tune and run oem ecu with jb4 for normal driving.

 

[Williamsj41]

I will also say I did try strait ms109 and it did perform well on timing. There was several problems tho it actually ran slower in the 1/4 because of the high octane heat resistance and slow combustion. That tune also is not calculated fuel scaling for that octane either because I was put in limp mode. Just cruising at 60mph with a cel the ecu was unsure of how much fuel it needed to inject in the cylinder. So far in testing ms109 diluted with alot of 93 has worked best. I will keep trying other things I'm sure there is more to find. It was also tested with the oem ecu and jb4 on map 5 it performed very well on strait ms109 and I feel like it pulled harder.

That's basically a jb4. It isn't a true flash, but it allows map changes and data logging.

Oh wow. This entire time I thought it modified the ECU directly.

 

[GTdsz]

The jb4 is a really awesome tuning option. It integrates into the CANbus through the obd2 and allows data logging. Then the tuning part has predefined maps specifically for the stinger. It is essentially a cobb tuner without directly flashing the ecu. I like the jb4 more than cobb.
