LAP3 ECU and TCU Review

[MMan]

LAP 3 ECU, stage 2,5 will be delivered tomorrow wednesday. Exiting!

Let us know what you think... I've been running the LOZIC TCU tune w/the jb4 map3 for a while now, and I'm still going back and forth between the LOZIC 1.4BAR and LAP3 stage 1.5

Interested to see some numbers from Corleone1 also. If you already have the TCU, I’m struggling to understand how a
ECU Tune, with potentially less boost, can make you any faster than a JB4 with Meth setup. Your TCU tune is giving you boost at launch, so basically a brake snip, and shifting for you at say 5900-6000 rpm. That plus a JB4 with Meth and your at 22 lbs of boost and shifting in the power band. The only thing I can see is if the ECU tune gives you 21 lbs of boost with little to no other supporting mods. Maybe then it makes financial sense. Can’t remember, but have we seen any logs with a 1.5 or 1.4 bar Lozic or lap 3 tune, running 93 octane, to see how the timing is holding up? Is it possible to run that with no meth safely? (Part of this is me saying to myself, I don’t need an ECU tune.). Playing devils advocate in my own mind, LOL.

JB4 is great. but it only has control over Boost, AFR and wastegates. ECU tunes have 100's of maps that are tuned on the back end and much like an OEM ECU will adjust based off certain conditions. (octane, weather, etc.)

Boost isn't everything.

The TCU yes provides launch control (brake boost) like brake snip. But, it also provides higher line pressure for faster shifting and torque limiters adjusted. TCU tunes alone shave about .2 seconds off most peoples 1/4 mile times.

Again, I don't have a meth setup on my car and its running 11.2 and that's with shitty 60ft and 3.1 0-60. I hit 20-22 degrees of overall timing and have 0-1 timing corrections at worst when running on E40. This is on E40 without meth

Again, boost isn't everything.

I just received last week a meth setup and I will be doing a full write up with plenty of Data, Times and Dyno. It should help a lot of people when trying to figure out what the best setup is. The LAP3 ECU is pretty impressive on adapting quickly to the different scenarios and you can really feel the difference when going form 91 octane to E30 to E50 etc.


DYNO, Logs and Times will include:
E30: No WMI or CPI running
E30/Meth: No CPI
E50/CPI. No meth (reason doing E50 and CPI is because with E30 there is no point to run CPI as the HPFP can handle it. Higher E content will need the CPI to relieve pressure from the HPFP.
E50/Meth/CPI
Obviously I can't do E50 with just meth because the HPFP would crash without running CPI.

Looking to get this write up with all the data etc within the next month but we will see. Its a lot of work.

 

[StingertimeNC]

That's strong no doubt. So wouldn't our stock ECU make all these same adjustments? Then JB4 says, hey add 7lbs of boost here, 6 lbs of boost there, etc. and you get all the power? The Dyno's will be great. I understand the TCU part a lot easier than the ECU part.

 

[Avant]

You can add a ton of boost with JB4. But again, boost isn't everything. There is a reason people with ECU tunes are running lower boost and running faster times . There are 100s of factors and boost is just one.

Yes, I will. I will also Dyno at same Mustang that I did with JB4.

About ECU tuning...

The advantage above PiggyBack like JB4 is that all tables that matters in ECU can be rescaled to have regulation with higher numbers. Like in JB4, lets say that max stock numbers in ECU for ignition is around 16 degrees and above that the table is not more changeable, then you can hardly tune and change in these areas. So with an ECU tune you can scale boost, ignition and also probably HPFP to have regulation at higher flows. That will change the basics to have a better tune. Then also all maps inside ECU communicate with each other and then wont be like manipulated numbers.

JB4 is a great tune if you will be pleased up to Map 3. With us with full bolt ons, we have reach the ECU´s inside maps limits and therefore there is a earlier limit in power with Piggys.

First impression LAP3 ECU, 2.5

Drive for 30 minutes for some adaption first:

• Very smooth running and shifts, like stock
• Feels that ignition is higher, better response
• Torque seems to come on faster without spikes
• Tried manual first, higher rpm but gently, seems that rev stop is around 7 k rpm and higher revs dont seems so limited like with JB4. Probably ignition here again that is higher
• Did 1 WOT in auto, feels stronger and log in JB4 looks that boost was around 23 at the most. No problem at all with HPFP, stayed at 10
• From standing still it seems like faster buildup in boost/rev
• So, unmanipulated seems very good and faster in asked figures
• I did leave my Windbooster in "Sport" and it works like I want the pedal. It seems that power is more linear compared to JB4 that will be more crazy when it comes on

It was rainy today so tyres did spun even in 3rd and 4th gear. Will be very nice to do some Dragy soon and also go to Mustang Dyno

"I´ll be back..." so far very impressing!

Awesome. What gas are you running?

7k is pretty high! haha. It doesn't boost taper though nearly as bad as JB4 (even with EWG wires). Usually I shift before 6k for 1/4, 0-60 times. Boost just stays as a flat line on the logs. I love it.

Torque does come on a lot quicker with the tune. I had to get used to launching the car and shifting 1st to 2nd because first and 2nd gear go so damn fast now.

Are any of these daily drivers and if so what fuel do you use consistently and what road performance do you see.?

Of course. 100% daily driven, drive daughter to school, etc..

I run a mix of E85 and 91 octane. Typically I run a blend of E40. Its pretty nice to put 7 gallons of E85 and save some money here in Cali with crazy gas prices!

In terms of road performance it drives like an OEM car with a ton more power. When you pop my hood, if you didn't know what you are looking for, it would look stock.

 

[Flynfishmedic]

Sounds like the way I will go. I want daily driver with good power! Coming from an S4 with intake,exhaust, ECU and TCU tune with virtually no maintenance needed but could catch most cars slipping!

With ECU and TCU it will make your old S4 feel a lot slower.

They are just plug and play. Engine bay would look 100% stock. Add in a few gallons of E85 when you fill up and the ECU will adjust based on octane and unleash some more power.

My friend you are making me grin from ear to ear!

There is a stinger with just an ECU and TCU tun running mid to low 11s with no other mods. Its worth it.

 

[Flynfishmedic]

Just take my money now!!

 

[Flynfishmedic]

I'm actually on the site filling out the form. Which ECU options did you choose?

Depends on octane you are going to run. The 1.5 tune is great for pump gas. 2.5 is great for higher E85/pump gas mix or running WMI.

There are plenty of 11 second cars with stage 1.5 tune.

I have the stage 2.5 because i run E50 with charge pipe injection.

 

[Flynfishmedic]

So this is my question. If I get the 1.5 will I cause issues if I use E85 mixed with 91/93 pump gas or conversely if I get the 2.5 will I cause problems if I don't exclusively use E85 blend?

 

[Avant]

No and No. The ECU' will adapt based on Octane. However, more octane = faster. Stage 2.5 will be faster with more octane. Stage 1.5 is plenty fast on pump gas and more octane.

I have ran my stage 2.5 on 91 craptane only here in cali and the logs still looked good.
