Wow, a couple days away from the forum and all hell breaks loose. As the exclusive dealer for Trifecta I wanted to shed some light on information which has been posted.

During development of the tune, Vince (TriFecta) logged well over 20 dyno runs in order to test the tune both with an without other after market performance parts. We acknowledge every car may warant a different air/fuel ratio setting for maximum power. The settings Vince uses in his tune are proprietary information so no specific details will be offered. However, when combined with the other tune changes he makes, we found his air/fuel ratio setting made the most power on the dyno with the test car, in Seattle, with local fuel quality, on the day the test car was dyno tuned. While also being a safe tune and not pushing the limits to an extreme. TriFecta prides themselves in offering powerful, yet, safe tuning for customers.

Trifecta has always included data logging and fine-tuning on the dyno via the GT Tuner (or EZ Flash) with every tune purchase. Some customers have chosen to take advantage of it, and have great results. If a customer chooses to send datalogs in and/or visit the dyno to try different tuning variables, Vince will schedule time to custom tune. Though many believe, and are trying to convince the forums members, the TriFecta tune is simply a "canned tune”, this is not accurate at all. With the GT Tuner and/or the EZ Flash data cable, the TriFecta tune is just as custom as ANY other tuning being offered by ANY and ALL custom programmers throughout the world. TriFecta currently is the ONLY company capable of offering "complete remote CUSTOM dyno tuning" in the world. As a customer, you simply need to schedule the dyno time and make arrangements with Vince while your car is on the dyno.

To date, we have sold well over 200 TriFecta tunes. Of those there have been NO problems resulting from the tune. When a customer does experience a problem, it has been determined to either be an issue with an after market part or a problem with the car; bad PCM, faulty injector, sensor, etc.

A customer who has been having a problem, most resently, has several issues going on. Much of the "inside story" has not been made public. However, since one of our services is in question, the TriFecta tune, I wanted to shed some light.

The customer has two different pcm's. one stock and the other purchased as a spare. he ordered the TriFecta tune and up-loaded the tune to the 2nd PCM. The customer was experiencing mis-firing before he up-loaded th tune. Next, he installed a cold air intake kit and went to the dyno. On the dyno his air/fuel ratio was all over the place. he didn't make as much power as he anticipated and he experienced problem after problem. Next, he swapped the stock pcm back into the car and the problems seemed to go away.

The customer has swapped his stock intake back onto his car and expressed to me there was a problem with the after market intake.

So here are some issues which need to be examined before ANY conclusion can be drawn.


1. is there a problem with the 2nd PCM? (Customer has not sent the pcm to Vince to be trouble shot).

2. does the TriFecta tune work properly on the stock PCM? (Customer has not up-loaded it to evaluate).

3. since the air/fuel ratio was so screwed-up on the dyno, has the catalytic converter failed as a result? (This would further add to problems)


Vince has sent several different tunes with different air/fuel ratio settings; four I believe. Each was up-loaded to the 2nd pcm and the customer expressed to Vince, the "original tune ran best and made the most power".

What needs to happen:

1. all stock parts need to be installed on the customers car.

2. Tri-Fecta tune needs to be up-loaded to the stock PCM.

3. 2nd pcm needs to be checked for problems.

Only then can the issue be isolated, detected and resolved.

Until this happens, it will remain impossible to determine what the actual problem is. Anything else is pure speculation.

When one customer of over 200 is experiencing a problem, all fingers point away from the tune being the cause. remember, The customer was experiencing a mis-fire BEFORE the tune was ever changed...

Thanks all.

 

On the dyno here, our choice of fuel mixture *combined with the other tune changes we make* made the most power.

Also note, the new Camaro V6, which is a DI V6 and uses the same ECU as the LNF has a WOT commanded ratio of 11.85 from the factory.

This has already been addressed above - I didn't say this. Lol

Other rumors to address:

"Psykosteveo taught Vince how to tune LNFs"

This is not true. The only interaction with Steve I've had is when he approached us about using the GT Tuner to distribute his LNF tunes but ultimately decided on another solution.

"GT Tuner is a derivative of HPT"

This is not true. To my knowledge HPT is a closed software platform. We developed all of the GT Tuner and EZ Flash software from scratch.

 

hows ur back dan?

 

This thread is fun.

 

seems like people are doing a he said i said he said. lol

 

13.2 is LMT on this motor.

why in gods name would you not work the cam tables? Christ your missing out on mid range punch and a touch on the top end.


ohhh, Hi.

 

Ill be seeing 06black in about a week to get my car tooned.. Should be a good time!!!!

 

[QUOTE=06black;3868422]13.2 is LMT on this motor.



why in gods name would you not work the cam tables? Christ your missing out on mid range punch and a touch on the top end.


Tried intake and exhaust advancing and retarding 3-4* and it made very little difference. It made an extra 5 whp or so in the low end and midrange an lost some up top so they are still stock.

 

This is a ridiculous thread. Why is everyone arguing over this tune anyway? If it makes 300whp safely and doesnt cause any headaches than more power to you. OTHERWISE, to prevent further e-fisticuffs.... I can recommend an excellent tune with a guy whos been tuning LNF motors since 2006/7.


OK, commence the virtual ass whoopings...

 

[QUOTE=Terminator2;3869237]your only working one table?

if your only finding 5whp, your doing it wrong.

by the looks of the dyno numbers, its not making that sort of power.

 

[QUOTE=06black;3870770]All four tables. Retarding the intake cam and advancing the exhaust cam it spooled up a ton better but fell off a ton up top. Advancing the intake cam and retarding the exhaust it started to knock up top and power stayed about the same. IDK spent over an hour trying different settings with very little change any suggestions?

 

[QUOTE=Terminator2;3870792]spend more time.

what spools wont make power, so pick a cross over point and then flip-flop your numbers.

work from there.

 

[QUOTE=06black;3870875]Ok thanks.

 

[QUOTE=06black;3870770]

I'm baffled by this. I have a tune thru GMRC. I have had it since February and have since then driven the **** out of it without error. No CELs, no hardware problems, no bullshit what so ever... ANNNNNND it puts down in the 300whp range at 23psi, AFR between 12.8-13.1 HIGHEST.

Let me give another nickels worth of free advice...

On my HHR .net forum I have seen this nearly identical argument. Some people had crappy luck with the trifecta tune regarding CELs and HP gains (seeing only an additional 20-30whp dyno proven...) Then again I have heard mixed emotions about cam tables and fuel mapping... I, for one, will not bad mouth a supporting vendor but I WILL play devil's advocate and note that I have had ZERO issues with my tune as well as a few friends around my neck of the woods with the same tune... and I am running advanced intake and ignition timing and a larger fuel curve through all the maps.

 

do they have multiple tunes they send out?

maybe some more worked over then others?

if this is not the case, its odd as to why carA makes 30+ more hp then carB

 

I have no idea. I am just mildly entertained by this entire thread. It actually made me laugh a little all the he said she said ****...

Hence why I just went through a private dealer for my tune. GMRC has been tuning LNF motors since the day they were born. Steve Kenniff and Martin Scott are reputable and run a good business. I honestly couldnt be happier, not only cuz of the power gains but because I dont have to deal with any balony sausage.

 

The question of why car A may make more power than car B; as I stated previously, car A and car B would need to be compared on the same dyno, on the same day with the same tune or at the track on the same day with the same tune. A car in Florida is NOT ever going to make the same numbers as a car in Alaska, etc, etc. There are too many variables to consider; again, as mentioned earlier, octane of fuel, air density (temperature/humidity), etc.

Thanks to those for not bashing supporting vendors. However, also please refrain from advertising for the non-supporting tune vendors.

 

Exactly, No two cars are exactly the same and some make more power than other with the same mods, tune and dyno in some cases. It is not unheard of for there to be a 5-10% disparity between two of the same type cars on the same dyno with the same mods and all.

 

i'm more or less finding there are two distinct factions of your tunes, ones that preform(and well at that) and another that has issues and week power.

not much, or anything in between...just two distinct groups.

5%, sure. 10%...meh, ok.

but were seeing changes of more then 10%, some as close as 15%

seeing how its an exponential change, those few % mean allot.

 

I hear you and I think a ton of it comes down to. 1. How sensitive these cars are to changes and issues. Ex. leaking pcv fittings on a lot of these aftermarket intakes. 2. We all know how weird some dynos read. Also some of the numbers you see are uncorrected numbers and some are corrected and that adds another 5-10% error to the mix.

 

add thouse up, and then i could see it.

its more the people with overly rich tunes or cars that dont run in an a-typical fashion that indicate an oddity to myself.

I've never had one car run peachy while another like dog ****.

and trust me here, I've tuned enough cars in my days to battle this argument out with any one on here.

 

I have a feeling... that HAHN intake is causing your issues... but yes 11's are WAY to rich!

 

What exactly are you basing this statement on?
The tune sent out to all customers is the same tune developed on the dyno. That car had every possible bolt-on performance part available used individually, all together and in every possible combination of parts. The tune was tested with the car in stock trim as well as with each and every part bolted on to make sure there were no issues. The tune was flawless in stock trim, and with a down-pipe, exhaust and boost tubing installed. The only time there was a problem with air/fuel and engine codes was after a cold air intake was installed. We trouble shot the intake and realized the breather hose was not secure enough. It was leaking and allowing un-metered air to enter the system after the MAF. The intake was removed and the car checked again. No problems. We installed the intake again and the problems were repeated. We removed the intake and the problems once again were resolved. This left no question as the what caused the problems with air/fuel; it was 100% the fault of the intake. This is exactly why we chose to NOT release the intake for sale.

Now, it is a known fact other intake kits being sold have had the same problem with the breather hose. Owners have had to create their own solutions to hold the hose on. With this being said, there is no way we are going to accept the tune as being the problem. In pretty much every case where a customer has experienced an issue, they have had an after market intake installed. Vince actually called me well over a month ago and told me: "Dan, in what i have seen with after market intakes for these cars, I think you should forget about selling an intake.". Not to mention other companies intakes by name, but Vince told me every one of the in takes available has caused some type of air/fuel problem on several customers cars.

When the same tune works beautifully on hundreds of cars with stock intake, there is no way the same tune is the problem on those few cars, with intake kits, having problems.

May I suggest you contact admin to become a supporting vendor and market your own tune.

 

What gear is everyone dyno'ing the car in....That could play a huge roll into this...In my experience Turbo cars are always done in 4th, as well as RWD (typically its 1:1) or 5th for cars w/ a 6speed. Dyno'ing for many FWD's is done in 3rd...which could lead to higher numbers

@ 120-130 mph my car ran out of steam (I blame lack of air movement and 6th and final run) 287/342 are great numbers considering I didnt have the fan blowing on the engine anymore (the switch went out).

Car has had no issues since being tuned (and has been tuned for 2500'ish miles)...Its just recently been running the stock ecm to get a baseline (and was at the dealer for 2 weeks getting some rattles fixed)

The only question really comes up as to who is correct w/ the A/F setups....Seems the leaner is winning, but I trust Vince and will have better same setup run next time I get some a day to run over to the dyno.

 

i agree that there are multiple intake issues, it seems to be a recurring issue.

what i've seen tune wise is based of looking around and reading posts on issues with this.

from both the cobalt world and rest of the LNF/delta community.

i'm not bashing on your tune, i never said i was, i'm simply seeing that group 1 is happy as hell, and group 2 runs across issues from idle quality, to power out put and such.

it just seems odd.

i would never become a vender on this **** hole. I've seen how the owner/operater works this place when people have issues, and to be honest. I dont have the spare time, nor the need for the cash.

tuning peoples car's as a side deal allows me to turn down whom ever i want. i simply just dont like people.
