Lozic ECU + TCU + AWD Tune

[Williamsj41]

I’ve heard that guys engine is toast and hasn’t posted here since august lol

The best shift points for the ecu tunes seems to be at around 5k from 1st to 2nd and around 5500 to 5800 for the following gears.

I already tore it apart and replaced the head gaskets a few months ago. It's running fine now.

Oops.. I’m glad to hear everything’s back together. You’re still at the top of the leaderboard on dragy!

No worries. My hundreds of trial launches and runs on the air strip messing with shift points and octane and all that led to its early demise. It's a good tune I'm sure hardly any other car went through that many runs. The car is winterized rightnow with stock all season tires, sock downpipes and I pulled the meth for now.
The best shift points I found was about a 7 psi launch at 2200-2300 rpm. 1st gear 4900. 2nd 5000, 3rd 5200, the rest at 5400. That got me in the 10s about a dozen times. Obviously the launch is dictated by the track conditions it helps at times to run a reduction in 1st gear if needed to control spin.
The most important part of the race is the 1st 60ft once you get that down it's easy. The rest is like auto pilot just hit your gears. And if you run e30 with 93 mix and 100% meth seems to be the best.
It is higher boost then some but I did find with that octane trying to hold 23 psi through the whole band the best you can provided the best timing advance for speed.

That’s understandable and still impressive for being stock weight/all season tires if I remember reading that correctly from the fb group.

With the Lozic Tcu what was your best approach to launching the car? Did you creep the pedal up to 2300 then floor it or just floor it and let go of the brakes once it reached 2300?

I would wait till the first yellow light on the tree lit up then floor it. And about by the 3rd light it will be crossing over the 2200 range and let it go if you shallow stage you won't be close to red-light. Or you can floor it on the first yellow and just watch the tack and release the brake when it's crossing over 2200 it will work about the same.

That’s similar to what I was doing when I hit the track back in December. I got about 7 runs in the day (all high 11s) trying different things and learned the hard way to avoid the kickdown switch (messed up a couple of my runs).
My best 60ft was 1.7 but I had just installed the Lap3 1.5 ecu that day and the conditions weren’t ideal (I was spinning the tires with awd, had to drop the psi down to 28). I also was only running e30 that day, don’t plan on doing meth/cpi as it’s still my daily. Looking to get mid 11s once it warms up a little here in MD.

Are these shift points when you pull the paddle or the target shift point?

It's when I pull the paddle

Supposed to get some dry days here in low 40s next week. I'll try these on the street and see what I run. Thanks for the tips.

Some Kudos to Lozic - I sent my TCU back to Lozic to have them change the logic of the shifting (I want auto-upshift in paddle/manual mode except for all nannies off - I don't like bouncing off the rev limiter in general). The package arrived Wednesday morning, according to USPS - today (Friday morning), I got my ship-back-to-me tracking number from Lozic.

They are SERIOUS about customer service!

How come you didn’t want it to not auto shift with all Nannies off?

This is perfect! Okay can someone help me understand if I’m way off base here. Most TCU tunes are either -5% or -8%. It’s well documented that our cars (of course depends the tune but in general) are faster when we shift way earlier. Most say out of 1st by 5,000 ish and all other gears 5,500 ish. So why has no one decided to have their TCU tuned closer to these shift points? Is there a downside or a reason I’m completely missing?

Do you know what RPM it’s actually shifting at in each gear? Or no reason to because the pull is timed and all that matters to be faster?

For the people who had the ecu for some time. Any issues? Best bar recommendations etc?

I haven't had mine as long as some others, I installed mine in September and have put about 4300 miles over the following 3 months. It's parked for the winter as I have 2 other cars. During that time it's been on a road course and had 3 separate trips to different drag strips. It's also been to "Mexico" another 10 or 12 times during that span. The car has done everything from bumper to bumper traffic to highway runs in Mexico over 160 mph.

I have had ZERO issues so far and my questions always get answered honestly when I reach out to @sweetboyed.

I currently have the 1.4 bar tune, boost ready (OFF), power by mode (NO). I have been very happy with how the car drives and performs so far. For everyday driving, I think those settings are perfect for me and probably most people. However, I am getting a retune because I plan to run WMI this summer, will be installing more performance parts, and was informed that I needed to go at least 1.5 for that safely. I like having all of the power available to me all the time and recommend it. I may also switch the boost function, but undecided. I have 93 octane everywhere around me so I wasn't too concerned about not meeting a certain power setting. Maybe @Slip_Angle or someone else is more familiar with the octane requirements for the different bar settings.

Hope that helps a little.

Thanks GennyGuy!

Since im from Canada. Going more than 1.4 on pump gas may be a problem since I don't have access to 93 here at all.

1.3 bar may be the only option for 91. Which I use 94 Petro, so far on map 2 jb4 which runs fine.

 

[Slip_Angle]

Generally speaking I would suggest the following

1.3 Bar - 91 Octane
1.5 Bar - 93 Octane

Several people have run 1.5 Bar on 91 Octane with no "problems" including me but it certainly pulled timing. When I spoke with Lozic, he said pulling timing wasn't an issue because ultimately this is how the ECU adjusts - same as stock. The car will protect itself. Of course the caveat being that the ECU shouldn't pull too much timing, which is to say more than 3 degrees consistently. The other important thing to note is that one companies 93 octane is not the same as the next. There is a great Canadian You Tube channel that tests octane from different companies with stunning differences in how much timing gets pulled and resulting power differences. On one he lost 30whp on a stock Audi. Anyways, I play it safe and run 1.3Bar on 91 octane.

Interesting bit of info as well... Lozic told me that his tunes will adjust power up if the the octane used can support more power. So in my case, with the target 1.3Bar at 91 octane, my power would increase if I used 93 octane or even a superior 91 octane. I'm not sure to what degree the power would increase but it's not a trivial amount. Our ECUs aren't trying to hit a target turbo pressure, they are trying to hit target power numbers and use turbo pressure and ignition timing to achieve the power output.

 

[AtomicGTL]

Thanks for the breakdown Slip!

I may go your route and go 1.3, maybe 1.4 to if am itching for abit more power. But good to know the ecu can adjust to the octane levels.

With all nannies off, it will not auto shift. But just with traction off, it will (now). That's so i don't constantly bang into the rev limiter at track days.

Sorry I’m sure my wording was terrible. Don’t you want it to auto shift all the time even when all nannies are off? Or is there a reason/time you don’t want it to auto shift?

He mentioned the same thing to me when I asked about blending E85 in. Said to use for my "special days" and enjoy.
