Lozic ECU + TCU + AWD Tune

[Pearly]

Honestly it could just still be adjusting... is everything else the same or did you end up trying an E30 mix? Does the driveability seem to be changing at all?

This is all still on 91.. but confused why sport is not trying for more PSI.

At this point. I feel like I just look like an idiot and need to shut up for a bit.

Best to ask Lozic what the strategy is... you can include him here or message direct.

I was reading through the JB4 forum and it appears that bit6 is what you turn on for running an aftermarket flashed ECU. Have you tried that to see if it makes any difference?

Also, definitely not an idiot haha you're not the first person to have a less than seamless transition into the Lozic ECUs but I have confidence that you'll get it dialed in and love it!

Correct- I had bit 0, 5 and 6 on. I hope we can get it dialed in. Until remap I’ll probably go back to factory. Thank you!

Also it’s hard to know what I want/need with the re-map when it’s been so weird.

 

[GennyGuy]

Yah it's kinda weird not having cold starts - the neighbors probably like that feature turned off lol

All it did was make me start shopping for an exhaust lol.

 

[GennyGuy]

I think it was just something way funky.. now in comfort and sport it’s 18psi but throttle opens all the way on both. Something is definitely weird!

It honestly sounds like you're trying to do too much, too soon. Be patient and let the car actually learn the tune. Consistency is your best friend when trying to figure out an issue.

I wrote BMS about which bit to run but Ando told me I didn’t need to enable anything, but I’m wondering if he didn’t understand my question? I asked which bit needs to be enabled for a flashed ecu and he said with fuel wires, nothing is needed to be enabled.

I have everything turned off with JB4. Map 0.

I have everything turned off with JB4. Map 0.

But looking at the N54 forum it does appear that bit 0 and 6 need to be enabled unless you have EWG wires with ur jb4.

Definitely this!

Update:
Plugs are installed

Just another update. I was sent the wrong tune. Order form was mis read. He is sending a new tune. I’ll keep you all posted.

Ahh that would make a LOT of sense.. unfortunate in terms of quality control but knowing Lozic they will get you taken care of and make it right!

Now it all makes sense lol Mistakes happen.

I was like Pearly seemed pretty thorough for awhile on ordering his tune and has had alot of issues lol.

Seriously! I was like, no one has had this many problems since 100 pages ago in this thread lmao

That makes a LOT of sense, and as lozic is basically doing all the work himself as far as I am aware, things like that can happen. with that many timing corrections, the tune you received was def meant for 93 or even higher.

Yes exactly.. he said it was 1.5bar and 93 octane. His mistake. And is sending the correct one now. I did change boost ready though. Also told him about cruise control. So we will see.

 

[Pearly]

I did put 4 gallons of e85 in. Timing corrections went way down (2.3-4.5) but boost never would go above 19 for some reason and sport mode felt slower than comfort. Back into factory ECU JB4 map2 hit over 20psi and most timing correction was 0.8

Without resetting the ECU, it was likely still anticipating the low fuel quality and would have continued to adjust and allow more power the more you drove it if I were to guess. With any fuel change like that it's recommended to disconnect the battery and let it sit for at least 5mins.
