Lozic ECU + TCU + AWD Tune

[Pearly]

1.4bar should equate to 20psi.. so yeah you're getting some extra boost from comfort it would seem. I do think the ECU will continue to adjust as you drive as many on here have seemed to report. Do you have any logs to post?

Maybe it’s not boost by mode.. I have a 3rd gear full pull (short log)

Pearly at this point, send it back to Lozic and tweak it.

Maybe someone who's sent ECUs back for a retune can chime in but, would it be helpful for Lozic to see good log of a pull through a few gears?

And yeah, it could be that it's 1.4bar across all modes. Depending on how severe the timing corrections are, you could try it just to confirm. But like @AtomicGTL said, since you're already wanting boost ready turned off, could be worth it just to send it back if you already know the adjustments you want made.

So.. I'm not an expert at reading these by any means so someone else can chime in. There's definitely some timing corrections occurring. Before I added E85 I was seeing 8s and 9s and after adding I now see .8 so to me it shows you don't have adequate fueling for the boost that's being commanded.

The odd thing to me is your "throttle" doesn't ever seem to show that you're fully flooring it. Only comparing to mine, it shows my throttle at 99 during my WOT runs.

Have you changed the plugs yet. The HKS should clean up the timing a bit

You don't have the gas for that kind of load, unless your foot was not actually pinned to the floor during the log, you're not getting anywhere close to full throttle

Is that what those low throttle numbers mean? Didn't realize the car would actually reduce throttle input like that..

 

[G70LEbyAdoom]

Yep, that's exactly what that means. Typically, the throttle will only go from 99 to 95 or 91 or mid 90's even high 80's. I have never seen it barely want to kiss 70 before. Something is very much up with either your tune/gas, or something else @Pearly

I’ll throw in some better gas and do a little more before I send back.

Do you guys get use to the boost ready? Constant blow off at low rpm is just too much I think. Something about it just feels too un natural. I think I’m going to have it turned off or do the 3,000rpm (so at least there on a roll race). Advice is welcome here! I just took it on a nice long drive thinking it would grow on me and it didn’t..The tune runs strong on the aftermarket denso plugs just an FYI. I’m still changing to HKS soon.

I don't hear it much to be honest. I have mine set not to turn on until 2200 rpm however. When I'm using it, I'm in a loud environment anyway because I'm racing or driving aggressively at that point. Usually with having dropped a few gears for a roll race. One "benefit" of boost ready is that the drone from my muffler delete is less. Idk how it is, but it is and I kinda miss some of the noise. Tune will run on Denso, but they usually wear out fast. I'd rather just have the better stuff (HKS) in there sooner than later

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

Better gas? where you not already running on the best gas available around you?

 

[Pearly]

Yes. I was running 91 (best available besides race gas) so I’m going to add race gas or some e85 and see how it goes.

We might have already discussed this, but are e85 and race gas readily available around you at basically every station? if not, then I wouldn't bother, cuz if your tune only runs correctly when you have extra spicy gas available, then its not worth daily driving the tune.

Yes they are.. but I don’t want to run them. I want the tune to run on 91. So I need the tune to be dialed down regardless. I just want to see if that helps currently.

So I have some interesting information.. I’ll make a log go show you all.

In comfort mode the throttle won’t open all the way.. but request 20-21psi.

In sport Mode the throttle opens all the way but only request 18-19psi. Like WTF???

That's really odd.. I'd like to see the log. I guess that does show there is some sort of boost by mode settings but they don't appear to be set up properly. Unless reducing throttle is actually how Lozic tunes the more "relaxed" feel in Comfort and eco..

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!

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?
