what are the differances between the two? is one better than the other?

Neither is better or worse than the other. They are just methods of custom tuning.

Trifecta is done by one guy with a lot of experience, and HP Tuners is done by any number of individuals with varying levels of experience.

Some HP Tuners owners can create a tune that is better than a Trifecta tune, others can't. The same applies to the LNF. If you're unsure of your HP Tuners tuner's experience level, it may be better to err on the side of experience and go Trifecta.

If you're asking about Trifecta Stage 3, then that is not necessarily a tune. It is an operating system that can be used as a base for a custom tune, whether it be trifecta or hp tuners.

 

I disagree. Trifecta cannot take AFR logs on the LSJ. Due to this, someone with HPT Pro with a wideband who knows what they're doing will be far superior to Trifecta. Obviously this doesn't apply to the LNF since it comes with a Wideband stock, and he can log it. This isn't a knock at Vince's abilities, but he can't tune what he can't log.

General rule of thumb:
Good HPT user > Trifecta > Canned tunes (OTTP, ZZP, GMS2) >>>>> Shitty HPT user

 

What exactly are you disagreeing with? I stated the same thing. Some HPT users can meet or beat Trifecta quality, others can't. That means that neither is always better or worse than the other. I merely forgot to mention the part about not being able to connect a wideband directly to the trifecta box.

I agree with the breakdown though. A competent HPT user has more data available to tune with.

 

"Neither is better or worse than the other. They are just methods of custom tuning."

I guess in general terms you're correct since you would count people who don't know wtf they're doing, but assuming you have a quality HPT user with you they're going to be able to do a better job than Trifecta (at least for the LSJ. For LNF it's a tossup).

 

Vince is acually pretty dead on with afr's even looking at a narrow band for afr's my commanded afr is 11.5 and wideband reads 11.6-11.4

 

Yeah I was gonna say, so what about 2.4s?

 

A narrowband will peg below 14 AFR, and is useless to tell what the AFR actually is when going WOT, so it's not possible he was AFR tuning off it. That's why I place a tuning solution that can easily accept wideband inputs (HPT Pro) higher.



As for the 2.4s, I am not at all familiar with the tuning options available. I think HPT has it unlocked, and I know Trifecta can do them as well. Since the 2.4 doesn't have a wideband, the general rule of thumb would apply here as well.

 

Trifecta is NOT arguably better than HPT for LNF cars.... you are horribly mistaken.

He can do tricks that aren't necessary, nor good for the stock turbo cars... PERIOD

30psi on a small ass turbo is just plain stupid... the fuel pressure isn't needed for a stock turbo car...


Now if you are a big turbo swapped car... your 1 gonna run a MBC for boost, then use Trifecta for fuel pressure but that isn't the full cure.

Every one of the highest HP LNF cars and LSJ cars are all done with HPTuners.

I'm not knocking Trifecta or Vince... I will actually be a vendor for him soon... but if you have a COMPETENT tuner use HPTuners if not Trifecta!

 

I was hoping you or BYT would chime in. I'll change my initial post to reflect this, as it's what I suspected. :-)

The trick I was referring to is the Select-a-tune thing where you can press your cruise button and it enables a different tune. (or something to that effect) I'd heard of the AFR disputes, overboosting, etc stuff before, but I don't follow LNFs that closely since I don't own one.

 

From my personal experience. Every car that I've seen come in and dyno with a trifecta tune then leave with a custom tune has gained power. Sometimes 5-10 but in one case of a tvs power ATOM it gained over 100 whp with a custom tune vrs trifecta.

 

My thing.... why would one want to turn off the tune....

Is Trifectas tunes that undrivable... because my HPTuners tune is just like stock driving around town.

I just don't understand why someone wouldn't want to leave it there!

 

For me I like to be able to go back to stock for the simple reason that I compete in stock for Autox. Other then that I dont really know.

 

To be honest I never understood it myself, but Judder makes a very good point. I think the other reasoning behind it is to "hide" the tune for when you go in for warranty work.

 

Theres also the fun you can have with it by having a mild mannered stock tune then switching to an all-out performance tune. Somehow that seems to be a lost concept though.

 

I suppose so....

 

Why would u want a stock tune? Doesnt make sense. My full out tune runs great on the street and strip. And gets awesome gas mileage. The switchable tunes are a gimmick.

 

BlackBaltSw has arrived. Throw all rational thought out the window. This thread is done.

People who can't keep an open mind aren't worth wasting time on.

 

you also realize that trifecta can log a wideband by hooking the wideband analog signal to a spare 0-5v pin

now i'm not saying trifecta is better.. but please dont spread rumors.. plus.. if you have a wideband.. he asks you to monitor the WB values and tell them to him if you dont go the route to hook up your analog 0-5v out so he can log it. not to mention he cant get exact with the NB but it reads in mv's which he can estimate to a CLOSE value of where it is .. he's been pretty good at estimating where it should be on mine based on his NB readins

as far as having a switch tune.. i know why my friend wanted it .. he races for money

he can run someone on "low" boost (gms1) and if he looses he does duoble or nothing and uses the TF 24 psi tune

further more.. the only reason he does the 30 PSI tune is because the customer requests it .. he's made it very clear that the stock turbo shouldnt use it but some people think boost = power.. and the fuel pressure mod is not something thats used on stock turbo cars

now there there are hptunes that put out better numbers but ive also had people go from being hp tuned to trifecta tuned for many reasons. the trifecta tune is only as good as the customer wants to take to do data logs.. unfortunately alot of people just get the tune and are like ZOMG MORE POWAH.. personally I do NOT let them do that

 

When I used a trifecta box at the bash, I did not see a spare pin for this. I could have missed it though.

When my car drops below 14.7 AFR my narrowband flips to 900 mV. At one time, I had my fueling set to gradually drop from 14.7 to 11.8 up to 3k RPM, and still have logs of it. The NB readings did not change in proportion to the AFR changes.

 

vince has said there are readings he gets in the 800s

and theres no separate pin specifically for it .. you wire it up to the ecm just like if you want to have an interceptor read a wideband

Vince can say whatever he wants, I'm pretty sure a narrowband doesn't work like that.

Why the hell would I go splicing people's wires just to get wideband readings?

 

did you just read what that was for ? lol

hptuners

and i could b e wrong about the narrow band.. but vince has estimated my afr before based on the logs and he's been pretty close .. like within .3

 

hptuners regular.

I have hptuners pro. It comes with one of these.

I just wire it up to the box, because I'm not going to jerry rig ****.
