Lozic ECU + TCU + AWD Tune

[Corleone1]

I must be doing something wrong since I can't get better times. Several of you guys are running much better times. My runs are on the street not track and map7 around 21-23 lbs of boost.. HELP LOL

Post a JB4 log in CSV format

Lower boost a bit and you get better times.

I have run map 3 (19 lbs) and map 7 (21-23 lbs) not much difference between the 2 maps as far as times go for me

How are you launching the car, without Brake Snip or a TCU tune I don't think you will see much better then a 4.0 to 60

Seen several guys with less into their car getting into the 11's and 3s without either a snip or tcu. I see stock cars getting my time and some even better

Ok, I got like some 1-4/10 of a second higher times with higher boost. Thats why I am interested of others Map 6, just to compare.

I'm really on the fence about doing the whole thing. But nervous about the language barrier and not much testing done yet. I'm hoping results start pouring in so I can feel confident and pull the trigger as it looks very promising

I’m right there with you. Interested in doing the 1.4 bar with pressure 2 or 3 tcu like robcoconut and calling it done. I only want to run 93 octane as it’s my daily and no e85 pumps near me. Might wait awhile until more people buy it and share their experience.

Good, I will look in some hours... Thanks!

11.25 DA was around 2200That was a 2nd gear launch at the drag strip without brake snip. The 11.02 is a regular 1st gear launch on full interior weighting 4135lbs. The last one was my best pull so far 1st gear stripped interior.

Thats friggin moving!! Again I should be in the 11s I would think without a problem.

Have you tried inquiring in any of the JB4 threads? Or emailing Terry directly?

Either are better options than where you're currently asking.

Seems that we have similar trap speed, (me 117,5) but you have lower time. Maybe it is the TCU that is the most difference as you can launch with boost.

I don't think it's just launch with boost, its the torque limits in 1st and 2nd. there's probably only 14-17psi then 3rd hits 22-23. I'm rwd so I may have more limiting happening. I think why this tune ends up being faster is because it will give you 22psi in first and second then third you can reach 25psi smoothly till 7th 8th. Also torque is limited in the ECU tune so less wheel spin easier traction faster times. unlocking our full 525+ft lbs in 1st and 2nd gear and trying to catch traction might not be as easy so he limited torque for better traction. Just my understanding of what he told me.

Yup just gathering stuff from multiple places and trying to figure it out.

What is the time section under the popcorn config area on the order sheet?

Time	Comport	0.5	second
	Sport	1.2	second

Jaybone and your logs!

Logs seems fine. Ignition is good. I think the map with lower boost can be faster.

If its was mine I had tried Bit 1 and put 125 in Fuel Bias to lean out a bit. Run that in all Maps by click Bit 1 and run several runs for adaption. No need to run under AFR 12, will affect High Fuel Pressure also and sometimes we can have like ignition missings but it is when HFP not can inject for the cylinder pressure is to high, then power goes down.

I think you can try Map 5 with Duty Bias 50 all over and FF WG Adaption start at 50 and then ev. raise FF WG in steps of 5. Boost has to drop more than in the Map with high boost. You can also start WMI at like 3-4 PSI so it starts as early as it can from launch at 1:st gear.

Do you have a dragy som you can figure out if more boost is better at like 5000 rpm and up. I see that you do shifts at 6000 rpm and that is better.

Had some improvement yesterday.

Just my understanding of what he told me.

So is this in the ECU tune, the TCU tune, or both? Are there any options forthe TCU tune in terms of torque limits?

I have a jb4, and I like being able to mix E30 sometimes, other times just run straight CA91 when I can't find E85 - just switch the wiper switch down from map 3 to map 2. It seems like with the ECU 1.5 bar map, I'd always need E30 based on previous comments? That's a no-go.

I'd love to be able to launch with a bit of boost (otherwise it takes a bit to catch some silly cars that think they can hang), faster shifts. I don't want 500+ lb-ft in 1st or 2nd - I'm worried it would destroy the center diff with that hard of a launch (I'm AWD).

Is anyone here on just 91 and using the ECU? If so what bar did you go with

 

[Jaybone]

Anyone on here running a Tork Motorsports tune?

 

[Slip_Angle]

1.3 Bar for me

 

[jakkwag]

1.3 Bar for me

You did 1.5 or something before too right? Im wondering because in another thread lozic said 1.2 is suggested for 91 but that seems a little low.
