We've been working on this for well over a year and we've spent lots of time testing and ensuring it's correct, but we've finally nailed it down and it's almost ready for production, and we're really proud of what we've come up with.

I'd like to introduce Trifecta ECP, or Enhanced Charge Prediction.

As everybody knows, one of the biggest challenges in modding LNFs, is tuning them for various intakes and especially blow off valves (BOVs). These mods can result in sporadic setting of P0101 codes (or other fuel related codes) and disabling of boost (or limits to 3psi) largely due to the sensitivity of the airflow sensors on these vehicles.

We've come up with some completely new tweaks that work with the vehicle sensors to allow for more wider variety of operating conditions when they report the data to the ECM. These new tweaks solve several problems that have plagued the community for a long time, including different intakes throwing codes and requiring re-tunes based on how the air filter is rotated (think the K&N SRI), not being able to run an atmospheric blow-off valve without relocating the MAF, and even then having trouble with the car not running right and hitting limp mode all the time.

So far the test results are very promising - we went out and broke every single intake rule there is for the LNF without ANY DTCs, CELs or boost limp mode. You'll be able to run a BOV with no problems, be able to run any intake you want without needing a re-tune for it. You could literally run a piece of pipe and a sock monkey as your intake and it would run fine. (We don't recommend doing that)

And here's the best part- If you already have a Trifecta tune AND own a Trifecta cable, this update will be 100% FREE. (your local dealer may charge you at their own discretion. If you do not own a cable and need to rent one, you can do so at the normal minor re-tune cost)

Now as I said earlier, this is NOT ready for production yet. We're in the beta test stage. So we need you- people with persistent P0101 codes, people running atmospheric BOVs, and people having limp mode issues related to intakes or other charge issues- to test this out. If you own a Trifecta tune and a Trifecta cable and fit the criteria above, please reply to this thread and we'll contact you. You do not need to own a Trifecta cable if you live in south florida and are willing to drive to me to get this installed.

Will you be running a group buy on sock monkeys as well? lol

This is huge news!

Really? welcome to 2004 of the internet.

This seems very promising. But, is it actually good for the car? Or is this more that people that just don't want a CEL.

Its meant as a funny comment....and yeah, its something that clearly isnt GOOD for the car and thats why Trifecta has spent a year perfecting it and making it available for testing.

You have an LNF...you should know better

The implication here is that the MAF is being circumvented. This is otherwise known as Speed Density tuning. Cars have been tuned this way for years, but never with such an advanced ECU as the one in the LNF (E69).

Trifecta has taken a huge step here. Time will tell, but given the fact that Vince owns an LNF-powered vehicle, and a BOV, and sock monkeys, chances are once this hits production it will be spot-on.

I'm thinking EFR with an air filter strapped directly to it...

Yeah this is GREAT news. This means I can keep my BOV VTA and have no skew or weird diveability issues, then Im all in

I like the way you think sir!

Maybe this can help me move my maf back to the intake and stop me from getting the maf wet after rain.

I am down for testing

Very interesting indeed. Subd

Can someone give a quick break down of speed density tuning. I have a decent understanding of MAF tuning.

What sensors does it use for the tune?

That's exactly what this will do. Shoot me an email with your VIN- customersupport@badnewsracing.net

It basically more or less works off of air mass calculations through the map sensor(s) and volumetric efficiency.

No such tables exist for the lnf unfortunately, however they do for basically all other gm ecm's.

Edit: No such tables are accessable through HPTuners at least. Everything is basically tuned via air loads, and through the maf.

Well its not really SD. Thats just kind of what it resembles based on BNR's post. As far as I can tell this is something all new.

For speed density tuning you need a 02 sensor, a map sensor, and an iat sensor.

NM, found a nice quick read

So Speed density is the ECU comparing RPM and volume/pressure/temp of incoming air.

Seems like this would help a lot especially when considering variations in setup. (air leaks, reading points etc) Which i guess is exactly what you said in the op

Would it be as reliable as a normal tune? Or an hptune?

Also, if were going off the other sensors, what happens if a map sensor blows or something?

Make the same power?

Pyros777

To my understanding Vince has customized the OS (hence the Enhanced Charge Prediction), so I would not forsee "hptune" being an option here.

This is not available using HP Tuners and probably never will be. It has nothing to do with tuning ability, these tables are not available through that software. Much like how Trifecta pioneered E85 on the LNF, and HPTuners had to develop something for their users to be able to do the same. Though I doubt HPTuners will develop anything to answer this with since this is essentially a dead platform to them since the cars aren't being made anymore.

We actually tested this scenario. You lose boost but the car still runs. Basically the same as if it blew on your current tune.

sponge14

Yeah that would NEVER suffer from heat soak.

Someone should make a "side winder" turbo mani and bring that bush to the front. Lol.

sub'd.. maybe I will be using my trifecta cable on my LNF after all

any expected timeline on when its suppose to be released?

Depends on how fast we get some testers
