Quick exhaust video with the LAP3 2.5 ECU tune and "crackle/pops" set above 3500 RPM. While driving normal I never hear them but going higher up on RPMs and decelerating you can for sure hear them. I set them higher in the RPM with the tune just so normal driving wasn't too obnoxious for me. My exhaust is pretty mellow so others might have it a lot louder with straight pipe. I have HFC primary then stock exhaust with mufflers replaced with resonators.

I've been running JB4 w/ WMI+E30 for over a year and have been very happy. I am becoming more interested in switching to LAP3 ECU and TCU tune. My question is can I still use the JB4 as a WMI controller and for logging? I am very happy with my WMI configuration and don't see a need to rip it out and start from scratch.

Yup, I think that's pretty much what everyone does who switches to Lap3 or Lozic etc...

Latest update after months of having the 2.5 ECU and Stage 2 TCU.

Still super impressed with this tune. I get in, start it and drive and it hits 11.2 1/4 mile pass every single time. No prepping, gutting etc. Just consistent every single pass. I do zero weight reduction on my car. Also I am not running WMI and just running CPI with E45-E50.

It only runs about 18-20lbs of boost. I have had zero issues, headaches, etc.. Just turn key 11.2 second car day in and out.

Nice. If only they had a way to run switch maps, so I could run ca91 when needed.

Or is this something jb4 could do with map 6?

I don't always have E85 available when out and about. So i have ran straight 91 octane with no issues. The ECU will adapt based on octane/knock. It will drive perfectly fine but timing will be a lot lower and wouldn't rip on it.

Also running the LAP3 ECU and TCU-

Is this fastest, stock turbos, full weight, daily driven Stinger in the world?

Dragy- 11.00 @ 125.95mph (peak 20 psi)
No weight reduction. On my way home from work.

That’s great! Seems like a nice setup.

All I can say is “holly shit”. Why didn’t I do an ECU tune from the start? Just received my LAP3 stage 2.5 ECU and Stage 3 TCU. It is seriously a night and day different car now and I am beyond impressed with these tunes.

Up until recent, I was running JB4 with Charge Pipe Injection and bolt ons. JB4 has served me well and I will continue to use it for my charge pipe injection as well as fine tuning AFR/wastegates if needed down the line. With JB4 I made 471whp and 510wtq and would run consistent mid/high 11 second ¼ mile passes and 3.6-.3.7 0-60’s. Simply put, JB4 is great but I quickly learned how much more a proper ECU tune can do.

After doing a ton of research, talking to multiple Stinger/G70 guys with different ECU tunes, I went with LAP3. There are several reason why I went with them. The biggest reason being communication. David at LAP3 answered every single one of my questions in absolute detail. He would then go into explaining how/why their ECU/TCU are tuned liked they are. They are a phone call away and very quick to reply. I hit up several companies to ask questions. 2 of which I never even received responses from after multiple attempts. After my research, I am glad I didn’t go with them as multiple people were having issues with their tunes and had to keep sending it back for revisions.

LAP3 Stage 2.5 ECU review: (plug and play right off the shelf)

ADAPTATION:

• I was very surprised to see how quickly the ECU adapted. It does adapt based on the fuel/octane content that you are running, and it adapts quickly. More octane nets more timing etc. I run E40-E45 which will lean out AFR however I was surprised to see how spot on my fuel trims and my AFRs were after very small amount of driving.

BOOST:

• There is almost no boost taper with this tune. The tune itself runs lower boost (18-19lbs) but it hold all the way to redline in every gear. I do not get any boost spikes when shifting gears and it is very consistent. I did a lot of research and after seeing people with other ECU tunes with some crazy boost spikes, or boost taper, etc. I didn’t want to take the chance grenading turbos/motor with massive boost spikes. A lot of people are hung up on running more boost, but it isn’t key to making more power or running faster times. LAP3 2.5 ECU has lower boost with a very consistent powerband.

TIMING:

• This was the absolute game changer. With JB4 I would get a max of about 15 degrees towards redline. Being that JB4 can’t control timing and the OEM ECU is limited, adding more timing made a huge difference with LAP3. However, adding more timing comes with adding more octane or WMI. The LAP3 ECU will adjust and add more timing based on octane being used. I run E40ish with no water/methanol and I am hitting a max of 20 degrees of timing. The good part is it’s throughout the power band and not just at redline. This alone made the car feel like an absolute monster and a lot of power was gained. (more to come on fuel/timing)

FUEL/WMI/E85:

• After speaking with David at LAP3, we had our concerns with me running the Stage 2.5 ECU without having WMI or running race gas. I run BMS Charge Pipe Injection which allows me to run more ethanol content and not crash the HPFP. No one has tried to run the LAP3 Stage 2.5 ECU without WMI/E30 blend, so I figured I would be the Guinea pig. Well, safe to say that the tune runs flawless with no issues on a E40-E45 blend. Going back to adapting and timing, Plugged the ECU in and went for a drive. I had the standard adaptive timing corrections which were about 2 degrees in every cylinder. Much to my surprised after a little driving, the ECU adapted and I get 0 to 1 degree of timing correction now. This is with having 20 degrees of timing throughout the power band. So, the ECU runs a lot more timing but it does hold up and run safe with a E40+ blend. Needless to say we were both happy and hopefully opens up more options for people wanting to run LAP3 ECU tune without running WMI or race gas constantly.

CONSISTENCY:

• Made this a topic because I feel like the car is sooooo much more consistent. I have done back to back pulls, logs, ¼ mile times etc and the car just performs spot on every single time. Today was 90 degrees out and the car still ran like a champ having higher IAT’s. Now we all know that weather/driving conditions etc. will change how the car acts. That is what is great about this ECU tune. Again, it adapts based on all these much like the OEM ECU making things safer and having much more drivability that is consistent every time.

OFF THE SHELF: Plug and play

• Received the ECU in the mail, plugged it into the car and drove. There isn’t a single thing that I would change about it nor does it need to change. (aka revisions). I know ECU tunes that are available offer “revisions” for X amount of dollars or X amount of time after purchasing. Sure, this makes sense down the line if going to a bigger turbo set up or something much more aggressive. Of course you are going to need a revised tune. I am more talking about the 99.9% of us who just have bolt ons. I have had several people tell me they had to ship their ECU back and forth to the company they got their tune from just to make it run properly with their full bolt on setup. The LAP3 ECU tune doesn’t need any revisions. It is legit just plug and play and done right the first time around.
• No more ISG (Idle Stop and Go) for Stinger guys. They now have the ISG (Idle Stop and Go) delete with their ECU tune. No need to wait for “beast mode” or launch control because of ISG (Idle Stop and Go). (idle stop and go)

LAP3 Stage 3 TCU review:

• Coming from a LOZIC stage 3 TCU, I was curious how much different the LAP3 would be. The main reason I went with the LAP3 TCU was solely to pair it with their ECU. Right off the bat, the biggest difference I noticed were the downshifts. When I had LOZIC, the 2nd to 1st gear down shift was sooo harsh and would take me by surprise every single time because of how abrupt it was.
• Launch control is a lot more consistent. Doesn’t have to be in stages and builds boost a lot faster (much like brake snip).
• Shifts are firm and quick. I went with stage 3 which might be a bit more aggressive for some but I love how fast/hard it shifts. I will increase your 0-60 and 1/4 mile times.

Ok, you just read a lot. What did all of this net me in terms of “gains”. Well, with full interior (no weight reduction), spare tire in, golf clubs in trunk, full tank of gas and on 20-inch 68lb wheels the car ran 11.3@ 120 MPH and 3.2 0-60 less than 24hrs after installing the tunes. This was with a not so great 60ft at 1.7x. With my track wheels/tires alone and cutting 1.6 60ft I see no problem hitting 11.0-11.1. Then maybe if I take all the crap out of my car (spare tire, golf clubs, seats) ill save another 100-200lbs . I have no doubt that it will break into the 10’s and get a faster 0-60. All without race gas or WMI.

My current mods:

LAP3 stage 2.5 ECU, LAP3 stage 3 TCU , JB4 with BMS Charge Pipe Injection, Fuel-it flex fuel sensor, BMS FMIC, BMS catch can, BMS intakes, SXTH Element High Flow Cat primary downpipes, DC catless secondary downpipes, Muffler delete with vibrant resonators, stock mid pipes, VT Snorkels, BMS trans cooler, BMS rear diff brace, BMS Billet strut bars, HKS plugs, 20" Niche Gammas, Eibach springs.

Some draggy times so far. I banged the rev limiter in 1st gear slowing it down a bit. I will update this thread as I continue to go faster.

Seems odd your running 18lbs of boost on the 2.5 ecu tune i have the 1.5 ecu tune and it runs 20-22lbs of boost through most of the rpm range running on 93 octatne. I also was running jb4 previous was big upgrade !

 

[mikegt2]

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

What kind of boost do you see with your lap 3 1.5 tune? just received mine couple days ago mine runs between 20-22 through most of the rpm range on 93 octane.

 

[mikegt2]

Wait - thought that was with the 2.5 tunes. Wow - how are the 1.5 tunes getting that low? Making it harder and harder to resist haha

From what i have seen the my 1.5 tune puts out more boost than 2.5tune ! seen many said there 2.5 tune puts out 18-19 lbs of boost mine is normally between 20-22lbs of boost through most of the rpm range.

boost will change on a lot of factors. I am sea level and 70-80 degrees. Its a bit colder today and I can hit 21-22lbs of boost no problem.

Here is a log from today. Colder weather so its boosting a bit more. ECU is pretty adaptive.

 

[mikegt2]

Ok, about 35 degrees here been seeing on average 21lbs of boost through most the rpm range and about 700 feet above sea level.

Pretty happy with mine then since it's only the 1.5 tune with 93 octane don't have e85 anywhere close so didn't want to go with anything higher plan on going meth next.

Yea 1.5 tune is a beast! Insane what guys are doing with it on pump gas! I have a WMI kit for sale if you are interested.

What's the difference between the stage 2 and stage 3 TCU tune?

 

[Avant]

What's the difference between the stage 2 and stage 3 TCU tune?

Line pressure. Stage 2 is more aggressive than stock. Shifts faster etc. Stage 3 is a lot more aggressive and shifts even faster.
