Lozic ECU + TCU + AWD Tune

[rpoffen]

Would be super nice if your company would use the EK1 Device for ECU/TCU Flashing, then we could very easily switch back and forth the different MAPS, and the map revision process would be a lot faster via email and not the old nail mail....... Just an idea.

BMS is supporting back end flash for the ek1 platform

 

[AdrianG]

Lozic claims the ECU tune for e85 will run with 100% 91 as well, or basically any mixture between.

 

[AdrianG]

Also, the numbers he provided me indicate about a 20% increase in power whilst running his tune with full E85 over stock ECU w/ 91.

AND apparently he is running 100% E85 without the upgraded HPFP, just stock with his tune. He stated that he will be going with CPI, I believe, and that the HPFP isn't even a consideration, apparently.

Yes, that is correct. There is actually a few different tuners using the EK1 Platform. But, if you have the correct software & plugins, anyone can use the EK1 Platform to flash the ECU/TCU.

Lozic and lap3 wouldn’t offer that anytime soon because those two has some special sauce for the adaptation values in the ECU that no one else has. But it doesn’t matter if you’re running backend flash with extra timing and JB4 to adjust boost as needed or just an aggressive full tune with CPI/WMI to max out the octane requirement all the time.

Finally going to pull the trigger on the Lozic TCU.. it's been a long time coming.

Curious on your guys opinion/input on creating a custom percentage per gear. Anyone done this? Pros/cons?

Looking back through the archives here, the OG 10 second Stinger stated he would paddle shift at the following:

1st: 4900
2nd: 5000
3rd: 5200
All others: 5400

Due to the paddle shifters being used I'm assuming the actual shifts occurred a couple hundred RPM later during his run.

I don't want to shift quite as short for general driveability but was thinking:

1st: 14%
2nd: 12%
3rd: 10%
All others: 8%

Any input would be appreciated!

You are going down the same road I was.. That is when they pull the paddle but just like you said In actuality the shift is quite a bit after. So if you set up your TCU like you have explained above 1st and second will be way “short shifted” way to much. I did my first TCU at -13% and it was too early. What I failed to realize is the paddle times you have above actually makes the actual gear shift around 5,800-6,000.(all gears) So you do not want to set it up like you have it above. At least I already made that mistake for you. Is your only Tune JB4 and if so what map?

Thanks for the response dude, I remember we were chatting on here before about options but you definitely made the leap before I did.. lol.

Good to know on the 13% being too much. Like I said, I was thinking along the lines of trying to match what, I think it was JWilliams, was doing for his 10 second runs.

Out of curiosity, did you do a dragy comparison or did it just feel like it was too short of a shift?

I'm map 4 running 91 with ~4.5gal E85

I definitely have compared dragy runs. I have now owned a -13, -11, -9 and currently on -7. (Yes I know I’m crazy!) If you have a most recent log you could send me I would definitely give you my opinion/ My recommendation on what you should pick. (801) 318-2380. Feel free to text me. But do remember how this is confusing..
1st paddle pull at 4,900 actual shift 5,800-6k
2nd-4th etc. so most gears are same ACTUAL shift point but different paddle pulls. The fastest g70 in the world target if actual shift is 5,900-6,200. And most other fast ones say actual shift they target is 6k. Wow well hopefully I made sense.

-13% is usually for people with tuned ECU and pump gas alone. The highend output for tuned ECU with tapered boost curve plus 4-6 degree timing pull will make highend output pathetic, hence short shifting makes it faster. Since you’re able to run map4 I assume your log is fairly clean and the highend power is there. You wouldn’t regret -8% especially if you’re going to CPI route in the future.

Hi guys,
I weighed my rims and tires all around they are 269.8 lbs, I have a 2018 G80 sport, and the tires are kumho's, fitted by the dealership when I bought the car. The question is, if I save 80lb of unsprung weight how would it effect my car performance?

Back in the old days a general rule of thumb was every 100lbs was a tenth of a second

That amount of weight reduction will show up best in the corners on a race track. Straight line acceleration will be effected, but it may barely be measurable. I don't think you'll see a tenth drop at stock power levels due to the vehicle already being over 4K pounds. It's a drop in the bucket.

Interesting, the car has a JB4 running map4 on E30, with a TCU tune -8 pressure 1, intakes, secondary DPs, and a Maintec catback the car in map3 is faster than a 2018 392 with intake and exhaust, 40 to 120 I was ahead by a car. Couldn't try map4 with him due to traffic.
I also bought sway bars front and rear, haven't installed them yet

Cuz map4 just supposed to be fast. My map4+meth without BEF is already 50/50 comparing with lozic 1.5+meth. With BEF my map3 is 3mph faster than lozic 1.5 now.

Sorry didn't get what you meant, are you implying that lozic is better than the Jb4 or map3 is better than map 4?

Map3+Burger or sxth Backend flash with 20 deg timing>map4 alone>lozic1.5

I was confused by your answer at first so I went back to read my original response.

I'm sorry, I'm saying that you won't lose straight line speed on just 80 lbs unless you are tuned also. Even so, 80 lbs will not see a tenth of a second drop in a straight. The car is too heavy for that weight to be felt on that metric.

However, around corners on a track, you should see a difference. The TCU Tune is making the difference on your straight line acceleration.

Yea see you lost me again, I have no idea what timing mean, I know that correction is bad, and I know how to maintain the car, but timing retard and advance, sorry it's not my mug of coffee.

So what you are saying is to save the money for more performance mods? Make the car faster by adding power and not removing weight. I just saw IMR turbo kit and they are claiming 900Whp, I'm not sure if that's possible or the transmission can handle that much power but a G80 AWD with 900whp that's a weapon of mass distraction.
