Lozic ECU + TCU + AWD Tune

[Slip_Angle]

Most automakers do a great job controlling their interfaces so they can guarantee compatibility across the lines. I'm not at all surprised that a 3.3t G90 ECU can run a 3.3t in the Stinger, and I'm not even opposed to it; I just hope Lozic is overwriting all the firmware and not just the parameterization needed to make more power.

@Terry@BMS said, "Yes, the flash side stuff has some differences. Maybe they forgot to adjust a table on the Stinger side" which is where my comment comes from. So far given the insane results on the G70 I'm really optimistic about this solution, but weary about the approach and unknown variables coming in and ruining the party.

How does the AF ratio adaptation work? Does the ECU keep long-term fuel trim in non-volatile memory? Feel free to point me to a more technical thread if this has been discussed already.

Good questions for sure and one's Lozic can easily answer. The issue is language barrier. Sometimes he tells me something but I just can't understand what he's trying to get across. (I'm sure I am part of the problem as well) Based on all my discussions with him, the tuning he does look to be first rate. He's tuning cars for the SuperRace and Nexen series in Korea and it sounds like his cars are winning. He also tunes every kind of vehicle you can imagine - from super cars like Ferrari's to tractors (yes farm equipment). We need someone who speaks Korean and knows a bit about tuning to talk to him directly and then translate.

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

Few more logs

Any updates on your TCU + AWD modules? or anyone else that's running the other modules?

Still waiting on parts from Korea

I was wanting to see if anyone knows what's going on here. Same fuel same adjustments even the same day and almost same weather. First it pulls and acts perfect. On the same drive it's like It hits protection mode and takes 10 psi average. Then when you pull the negative cable for a reset timing goes out. These are the little grimlings the stinger has.

I have experienced all you have, haven't had a chance to send him ecu back.

I think it’s never good to reset the ecu just to correct timing corrections. It’s just fixing the problem temporarily and the ecu will revert back.

 

[Williamsj41]

I don't like doing it. I did see where it said if you are changing octane it can be good to do it. As of right now I am trying to change octane a little on each fill up to see if it will act better or worse with one over the other.

I don't know if he's still around but

I don't know if he's still around but @xot1 is the guy y'all need to talk to. He's in South Korea and is familiar with tuning.

Thanks, I reached out

ECU will adjust to your octane. I was running 91 and was getting -4. I started filling it up with 91 and E85 and now getting .0-.8 corrections. I’ve never reset my ecu. I wish we had 93 here.

I know I responded to you in another thread but I can run 93 octane on map 1 and get 5-6 degrees of timing pulled that makes no sense. Plugs are good so that should not be happening. What version of JB4 are you running? I'm wondering if its the most recent version 21/24/5 is causing some issue on the timing correction side?

 

[Williamsj41]

I do agree I do not think the ecu reset is good all the time. In my particular case I don't feel like it was an issue. Because I had not done an ecu reset in a few day I even adjusted my E mix from E46 down to E36 without a reset. It was running just about the best I have seen it and out of no where on the same drive to work about 40 miles after the adjustment it just decided to go off and reset to factory psi levels. Only after that did a try the reset and it did not do any good it actually made the timing alot worse.

I’m running that firmware as well. Email Terry and them or post a log on N54 tech forums.

 

[Jaybone]

Did both and waiting for a response. I posted in a couple areas as I'm not sure who sees what.

You all running ver 21, can you try valet mode. Just curious, I tried valet map 8 and it was like map 4.

Yeah and .8 is what I see regularly on stock runs.

I spoke with Xot1 and he will assist if there is a specific question.
