Lozic ECU + TCU + AWD Tune

[Yves998]

Yep, need that proper pump gas. Also Lozics suggestion is to launch at 3000-3200 rpm. But I found my sweet spot was definitely 2600-2700, to each their own. Also upshifting around 5-5600k rpm which I never got to do (( lol

Slip_angle launched fairly early in the 2000s and upshifted at 4700 from what he mentioned to me. You can try that since you both own the same car.

Ok now I know why I’m only doing 4.1 sec constantly while everyone break 4 sec so easy. Guess I’m being puxxy for launching at 2200-2300. I’ll go launch at 2700 and see how much gain it gives me.

Here is the response from Lozic so far- in case any of you are curious.

Let's check more about the cruise control mph indication.

You are right that the Boost Gauge is higher in eco comfort.

The boost and power of ECO comfort are not made by direct setting, but you can think of it as a method of forcibly limiting the maximum power of Sport.

And since the boost gauge is a sensor mounted on the outside of the throttle, it is displayed higher because of the throttle limit.

The boost pressure of the actual manifold is lower.

So, the way I'm interpreting that, the difference in throttle input you're seeing between modes is actually how Lozic is creating his "boost by mode" capability. So the car is tuned the same across all modes but he limits power by reducing the throttle input effectively reducing boost?

Exactly

If I go look at logs.. now I look at boost 2 column instead of boost. And this makes more sense.

 

[Seeing_Red]

Exactly

Interesting! But as of now, you really haven't noticed a discernable difference between comfort and sport? Seems like you'd notice a difference right away if that's how it's set up

What is boost 2 tracking? I've never paid attention to it. I looked at one of my logs and the numbers in boost 2 are very similar but slightly off from the regular boost column. Although the differences are +/- .5 at the very most

They are only different in comfort mode. Sport mode is within .5- Comfort mode example will show boost of 19 but boost 2 will be 17ish.

Sport didn’t seem faster but could of been subconsciously.. I’ll do draggy tomorrow

Alright everyone.. opinions/help needed. I just did my first few pulls in Sport mode (supposed to be 1.4bar)- maybe I need to let the ECU learn more? But the peak boost in comfort mode is actually higher than the peak boost in sport mode? That was the issue with the last tune as well. I thought it was because it was an incorrect tune etc.But there now has got to ge a reason for this right??? Also this tune has the same throttle readings.. meaning comfort mode it rarely makes it to 99. But in sport mode it makes it to 99 just fine. So my guess is this has something to do with power by mod and how it’s controlled. Regardless I thought I would feel a nice difference in sport and honestly I didn’t.. I could do some draggys to be sure? Or maybe be more patient? Also today was the hottest day of the year here as well. All thoughts and opinions would be wonderful. TIA

Forgot to add timing is wonderful with this tune though.

Maybe the air temp is to blame for the car not feeling faster in sport on your first try? How hot was it? Also if the boost gauge reading is skewed as lozic explained, leading you to believe it shouldn't be faster. I just got my stinger, but my previous turbo car was noticeably faster in cooler Temps. Perhaps peak boost cannot be reached with the low air density on hot days? Someone who's run in warm Temps chime in?

How are launches with boost ready turned off on low rpm? I'm not entirely sure what he means by:

"However, if Start RPM is not set to ALL, Launch Control Boost cannot be operated"

 

[StingertimeNC]

Boost is actually higher in hotter temps, and lower when cold. Colder air is more dense, so the engine can create more efficient power at lower boost. In hot weather I'm seeing up to 23lbs, in colder weather I see 20-21. Both in map 7. Either boost level can create the same power.

So without having the TCU tune.. you can launch on boost with just the ECU tune- if you have boost ready always on. If you don’t have boost ready always on you would not be able to launch on boost since launch mode doesn’t go past 2,300 rpm. That is what he means by that. Hopefully that makes sense? I have the TCU tune as well so that is why it’s okay for me. If I didn’t have the TCU tune I would chose boost ready to be on after 2,000 rpm that way it’s not too aggressive for a daily but can still launch on boost as well. (Some people love boost ready always on regardless)

That makes sense now, thanks very much. I'll be tcu as well. I think I'll do 2k or 3k for boost ready, unless 2,200 is an option to allow me to cruise at 83 without, yet still launch without having to hit 3k. I asked lozic, waiting on reply.

I have a question about boost ready. If you choose 3k, does that mean the car will not build boost at all prior to 3k? Or is boost ready a separate function all together?

2,200 is an option. Several here have it that way actually. Mine is at 3,300. Also it is supposed to deactivate when cruise control is set. 2,200 is a great spot I think! The best way I can describe Launching with just an ECU launch without the TCU is it’s like a medium launch- meaning faster than factory by far but not full send like TCU torque off etc. Or also kinda like a safer way to launch on boost. So it can be nice feature to have. Although once you have TCU it’s hard to not just full send anyways!

Boost ready is a separate function. It definitely still builds boost before 3k (same as factory) Just after 3k boost is achieved way faster and with less throttle- I’m not mechanically inclined enough to explain how it is achieved. Although I know logic said the blow off/bypass valve is more used when boost ready is going.

The best comparison that I can come up with of boost ready, its like having a pedal commander or one of those devices, but without actually having said pedal commander.

Pearly should go the WMI route too

I also found out lozic bases the 1.4bar etc off of 4th gear. So peak boost will be low rpm in 4th gear. So this is why my peak I have seen is only been 19 ish. Just is interesting when map2 has a higher peak in lower gears. But maybe I use map6 to up it just a touch. Wish I could up in in gear 2-3 only!

Peak boost doesn't mean faster. I guarantee the Lozic 1.4 will be far superior to JB4 map 2

I feel ya. I can have some fun and do some tests.

 

[Pearly]

I'd say since you have jb4 if you want more boost and you have the octane to do it just add a few lbs via map 6.

Have you tried this yourself?
