Lozic ECU + TCU + AWD Tune

[Slip_Angle]

I'm running E30

Ok, if I'm reading this right it says it's pulling 2.3 degrees across all cylinders. I have also seen this in my logs with the 1.3bar tune. I have heard from another person that has seen this as well. It seems way to coincidental that three or more people all with different tunes see this exact condition. I don't know the cause but it feels like timing is not actually being pulled due to knock detection. It seems almost like a programmed response? or maybe with the Lozic ECU, JB4 doesn't read the ignition correction right in this specific condition??

I just had another look at my log. It appears to show 2.3 across all cyls right when I let off the brake in LC and doesn't change until I let off the gas. Even shifts don't impact it at all and timing increases with rpms and still no difference.

There’s no way the ECU is reporting timing pulled without there being a need for it. To believe the correction factor is inaccurate can potentially prove to be a very costly mistake.

The other people experiencing the same condition aren’t occurring by happenstance; you all have the same bench tune, with perhaps slightly different max boost settings; otherwise, they are identical and therefore exhibit similar timing correction factors.

I don’t know what’s going on with the Lozic tune, but I hope it can be worked out because that’s the route I planned to go down in a few months.

Hopefully, it’s just the growing pains of a new product, and the issues can be sorted out. It does blow to mail the ECU back to Asia for reflashing, but it’s a small price to pay compared to the cost of a new engine. It’s all trial and error until a balance is struck, given the atmospheric conditions and fuel available abroad.

I am so interested in hearing how this transpired. Couple questions for the boys who have it as I’m a bit confused.
Do you have the mode specific tune?


Who went with the burble mode? This is interesting to me as to how loud it is, what modes it works in.

What’s your overall impression of the tune of the car feel fast? If you had a JB4 How would it feel with respect to a map 2 tune?

How many went with the all Wheel drive TCU tune?

Sorry for the questions I just want to make sure I understand exactly what you’re purchasing calm and I want to know exactly what you’re experiencing

There's always Tork Tune. Proven reliability, CONUS shipping, consistently low 11s, 3 years experience tuning Stingers...just have to deal with a shaky personality.

There's also Pressertech if you just want to spend a lot to go a hair faster.

Oh, I agree but I'm seeking to understand. My logged runs look pretty clean overall but this is an outlier that makes me curious as to the cause. Pulling 2 degrees of timing isn't a big deal in the grand scheme. The ECU will always adjust timing depending on several factors, you can see that when logging a stock car as well. It's intriguing that it's not just my car and there is no variation. Typically knock control would show some level of variation. Could this be a torque management?

Does everyone who’s having issues with the Lozic tune also have a JB4 installed to check logs? I’m wondering if your Map 0 is interfering with the new ECU, trying to bring all the values back down to what it interprets as stock? Basically, maybe your piggyback and tuned ECU are battling it out, your engine being the fighting ring?

That’s not how the JB4 works. On Map0, the unit does nothing but log. The JB4 provides no additional input in Map0. In essence it operates as a read only device. Also the JB4 does not “bring values down”, there are no modifications to the ECU when using the JB4. It modifies signal input to produce a desired effect. It’s also worth noting the JB4 does practically nothing in any mode until you go WOT.

I understand, but I think I’ve seen a couple tuners say to not run an additional piggy back, so just trying to rule things out before anyone blows something up.

No, I DO NOT have JB4 And also have the issue . I do not believe it is as bad as redchromastinger but I think his tune was 1.7bar and mine was 1.5.
So nothing to do with the JB4

I get what you’re saying but on Map0, that statement doesn’t apply. What they mean is to not run an active piggy back that would alter the signals produced by a flashed ECU. Map0 does not do those things.

I asked Terry about that yesterday and he did confirm map 0 is jb4 completely disabled and logs only. Even lozic posted in here that the jb4 was not interfering. I did put the lozic tune back in yesterday and played around very cautiously. My car did not make the oscillating sound until I put primary, secondary, and catback on. With the hks bov makes it more clear to hear. It appears watching the jb4 the car is holding 1-3 psi of boost cruising at highway speeds and the bovs seem to be on a constantly blowing off the boost that is not needed in a regular pattern.

 

[Williamsj41]

I did even attempt to run it on map 6 with ewg wires set a boost target of 0. Duty bias on 45 ff adaption to 40 pid gain 20 auto shift reduction 60. And at around 3 or 4 seconds in sport mode of 97% throttle it hit 24 ecu psi spiked 27.7 boost1 but throttle blade was slaming shut boost 2 was only 9.8 at the time. But boost 2 hit 23.1 before that. And fp_h had dropped to 6 1 line before that.

The troubles you guys have sound similar to something I had with my BMW 535i.

I had a blown Diverter Valve and bad Boost solenoid. At first I was having drive train malfunction with low boost issue, car was performing very badly / not powerfull. They changed the Boost solenoid and redo the car adaptation. The problem was still there and now even worst.

They then decided to change the Diverter valve and gave me back the car. After that the car was boosting like crazy but was also getting drive train malfunction and the diverter valve was making rattlesneaks sounds. I ran some JB4 log and the car was always boosting way over targets...

I went back to BMW and convince them to redo the boost solenoid. They did that and now the car was back to normal. It seems like they did not redo the adaptation when they changed the diverter valve so the boost solenoid was compensating like when I had a blown diverter valve which led to over boosting car...

I do not master how the Stinger engine works but it sounds like you guys are boosting over target. Could it be that the sensor that manage the boost and call the diverter valve to open to let go some of the boost go is not "adapted" to the new ECU targets (if that make any sense) ?

 

[Williamsj41]

I am going to assume that alot of the overboost problems atleast on mine is changing the whole exhaust system from turbo back. Really opened it up but lost alot of the back pressure that was helping it not overboost as bad. Since I did not have the tune selected for that modification. I will say I did try the same ewg adjustments that make the jb4 happy and stop overboost with the lozic tune and it will require even more adjustments it's still boosting right through what the jb4 liked. And before that alot of it seemed to be related to the tune needing higher fuel quality then 93 with boostane. More along the lines of race fuel or strong e85 mix with cpi to add extra fuel delivery. So far turning duty bias down to 40 I have not overboosted today. 64 degf ambient temp.

I had tried the adding the e85 but didn't adjust the egw. But like you said tune isn't made for our level of mods. Even though I stated all that was done. I think a correction for out mods would probably be sort with 1.3 bar or lower with 91 which will probably equal to our 93 octane in the states
I found 100 octane near by but that will only correct one issue. Boost level clearly needs to be managed correctly by tune its self.

 

[Williamsj41]

So far today I have not overboosted with the ewg wires and map 6. Boot target 0 duty bias 40, ff adaption 40, pid gain 20, auto shift reduction 60. You can try that if you want.

I was gonna ship lozic the ecu but I will try it
Did you change bit 6 on?

 

[Williamsj41]

Yes I did switch bit 6 to on. You might have to adjust your ff adaption and or duty bias down a bit. Since your tune is 1.7 I'm not sure you might have to play with it a bit. I know lozic said they do not use any ethanol fuel in Korea. He only has a e85 flash from his race team car. Unsure what Mods are on that car.

 

[RedChromastinger]

I will try it until I'm able to get the 100 octane just filled with 93.
Will are you running meth aswell

 

[Williamsj41]

No meth I am actually running 93 15.9 gallons with 51 oz of vp octanium unleaded booster if their mix is right it should be 100 octane. Dose is way to high to sustain daily driving it's just trial. I'm sure it's not quite as pure at 100 octane. I do have sunoco 260 gt plus about 2 hours away I will try it one day soon. My primaries are high flow cats so if you are catless you will probably have to lower it more on the adjustments.
