Topic: Enhanced Charge Prediction- New Tuning Feature

[BNRacing]

This was posted several months ago on the cobaltss.net forum, and we thought it would be good to post it here also. This is a new way of tuning the LNF so that you can run atmospheric BOVs, custom made intakes, etc. without needing to do a MAF relocate. It's SORT OF like Speed Density tuning- but there are some differences. We still use the MAF for some stuff, like humidity and temperature.


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)

Yeah I think there was already a thread about this here back in like June.

Ok I just want to make sure. I saw some misinformation about needing to do a MAF relocate to run a BOV and that just isn't true anymore.

Sorry, but THAT'S misinformation. ANYONE that knows anything about tuning wouldn't run a MAF in front of a turbo with an external bov. Actually, anyone that knows anything about tuning wouldn't run a MAF in front of ANY turbo setup. Blow-through MAF's work better for many different reasons. What Vince is doing is what he usually does, goes about trying to fix something the wrong way. Sorry but this type of tuning on the LNF has already been shown to be not necessary at best, and at worse, not even close to the drivability of a solid MAF tune. How hard is it to move the MAF anyway? Pay some local welder $20 to weld in a MAF mount and you're done. That's the RIGHT way to do it. If you've put in the time and money to do a big turbo, or external bov, going to a blow-through MAF is not only fairly cheap and easy, it's WAAAAAAY easier to tune and get perfect drivability.

I've said this many times before, and I'll say it again here... Vince is probably a decent guy, and probably a decent programmer, but he is NOT a tech that understands basic engine operation. The way he goes about things is just plain wrong. Look at his LNF E85 tunes. Horrible. Look at his "fix for all the fueling issues on the LNF". Totally bombed because the theory behind it was wrong, or actually non-existent because he didn't actually understand the "fueling issues on the LNF". I see this new idea he's pushing as the next "Infiniboost". Just a matter of time until motors start blowing. There's already been a few frustrated customers that have gone back to their regular tunes. This is a band-aid to an improper hardware setup that should be made right anyway. Vince should not be doing this kind of tuning without constant logging on every single customers car. Oh wait, his logging doesn't show half of what's needed to be seen anyway. You can't tune or even understand what you can't see.

Sorry if that's a bit harsh, that's just how I am. Straight to the point and no BS. What I've said here is the truth. Sorry if the truth hurts sometimes.

Well, um. Yeah. I dont understand why there is a need to remove the MAF. If your putting on a new intake that makes the car run like crap, its not the right intake. Do it right. But i dont have a clue about all that technical stuff.

Everyone is entitled to their OPINION. But we have thousands of ECP tunes out there on LNFs and others. Believe what you want, but the facts are the facts- ECP runs great.

Well say it then

[Gentleman Jack]

What am i saying?

[elff]

That Pink is the new Red

[Sol Asylum]

That Pink is the new Red

Does that mean Sammy Hagar is now the Pink Rocker?

[elff]

I am kind of scared to think about that.

[tazz]

What !!  The Pink Taco?

Looks like we're there.
