Haltech drawbacks vs PFC
 

Is there anything a Haltech 2500 can't do that a PFC can?

I've done a lot of searching, lots of old info, wondering about the current state of Haltech.

No.

it cant be 90s jdm cool.. as far as im concerned thats a deal breaker. pfc4lyf

Cool, glad it's that cut and dry. Thanks.

These aren't comparable. One controls an engine, the other is a programmed guess. What's this searching you speak of? They aren't even in the same market...

You can certainly compare them. They are the two most popular aftermarket FD ECU options. Not comparing them and looking at the pros and cons between them is somewhat retarded.

Clearly you haven't used them both if you believe this.

PowerFC - Rudimentary Millisecond Based Junk with VERY Basic Sensor Data and Zero Vehicle Control Functionality Beyond AC/Idle Compensation:

Haltech - Modeled VE Multiplier (Not True Airmass, but Calculated Good Enough for Most):

If you are comparing these two things, I'm sure your commute to work is real interesting on the days you decide to take the Giraffe instead of the Honda.

These are not comparable.

Hey, look at that, you just compared them.

Go somewhere else to get your post count up

no offense but if thats what you are going to show as a solid comparison between the Power fc and the Haltech, it doesnt appear that you know what you are doing with the FC-EDIT...

"You can't compare them".

Compares them in his very next post

So between your 7000 Posts, you three sound a bit daft. Haltech is a great consumer grade ECU vs. PowerFC is a great wheel chock.

Back to the same rhetoric.. dont you have anything better to do? Go tune all these imaginary cars you have been claiming to be tuning all day and give it a rest about the pfc.

Costas, you'll never move forward in life if you continue doing the same thing, on the same 90s nostalgic platform and design logic.

Your other stuff is just a personal jab. No point in arguing. Can't please everyone.

Care to elaborate on this baseless bs claim? 🤣🤣🤣
You obviously do not know the slightest detail to make this idiotic claim. Not moving forward? 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
if someone is not moving forward its someone who has this obsession with the pfc who wont give it a rest after trying so hard. I have been avoiding responding to you because it will lead nowhere. When i responded here i had no idea who you were but it didnt take long to figure it out. I have regretted answering to you as I like to avoid people with this kind of behavior.

What other stuff is a personal jab? I have never spoken to you before and im surprised you even know my name lol.. not that its a secret but whatever. I cant wait to hear all of these things

Wasn't this guys other account banned?

Probably.


As for the PFC, there are probably more FDs running the PFC than all the other aftermarket ecus combined. It does a perfectly adequate job for 95% of the modified cars out there. It used to be the only option for stock style sequential control.

Like many people I'm sure, my car had a PFC when I bought it.

Haltech has come a long way with it's rotary support. It wasn't always like this.

PFC is heavily supported, even more now that we have FC-Tweak software and the PFC tuning notes group. It's still a very viable choice, especially if you already have one.

I started this thread to have a simple question answered, and it was answered. Now it's just a bunch of people arguing.

Welcome to the internet. 😂

And just because I’m bored, I’ll throw fuel on the fire. Discounting an ECU because it uses pulse width mapping is certainly daft. Probably 2/3 of the grid at LeMans this year will use ECUs with pulse width mapping. VE had absolutely no benefit to a running engine over pulse width. It’s benefit is that it’s easier to setup and get close because the calibrator doesn’t need to do math on the front end.

The focused part of what I wrote was that one controls an engine with basic sensor data while the other is a calibration for a vehicle. Haltech is still only mid-tier in the real world, but hey, they're accessible and priced accordingly.

The focused part is that you have no clue what youre saying. You are responding like you are a 5 year old.

Calls us "daft" then snivels about personal jabs. What a root smoocher.

In the real world, finding a good tuner who is familiar with the car and computer, and has a record of making cars quicker, smoother and more drivable has a lot to do with the equation.

I'll drop my 2 cents just for fun

Haltech 2500 vs PFC in simple terms, the PFC is cheaper and easier to setup, uses stock wiring and is limited in that sense and does not have protections features like fuel press / oil press protections, etc. Can only run in waste spark ignition, and 4 injectors (can run more but it's not straight forward)

Haltech is more expensive and can be setup PnP with stock engine harness or fully custom harness with whatever sensors you want, direct spark, more injectors, engine protection features, etc

In the end, it all comes down to what your tuner knows and what you're doing with the car. For example some of the fastest drag rotaries in PR run Microtech which some think is ancient and limited.

Not related to Peter Giljevic (harder on housings than SCR) are you?

There is no significant difference in the main speed density input sensing setup and fuel and ignition functionality for the way 95% of people will run a 13b in a registered road car. VE is just easier for muppets to understand than a time to volume flow relationship, both run dead time compensation so it the same thing.

What the haltech allows is fail-safes, warnings, logging and integration with other functions and CAN devices. Also allows people to run baro compensation or IMP:EMP main load table and fuel pressure compensation, flex fuel. Again, great to have if you will use them but none of which were highlighted in your post, which suggests you don't comprehend the basic multiplicative mathematics of the fuel models.

thats a name i havent heard in a while ....i suppose this is a toned down US version LOL
spot on on your description

Someone doesn't understand basic English colloquialism.
In English, "You can't compare them." Implies that the two items are in completely different categories for design, performance, purpose or many other categories. It means that there is an obvious and significant advantage to one of the compared items over the other.

IN THIS CASE: The results of the comparison is 100,000,000% obvious to anyone with basic knowledge on the subject, therefore, what he said makes sense, and you make yourself look like a tool by going off of the literal meaning of the words when the purpose of his statement was obvious.

Yes.
