Obviously we have fans of both ECU's. I've come to two options, there are as follows:

1.) Replace my stock wiring harness with a new one from Mazda ($778), throw in an HKS Twin Power ($300), and stick with the PFC and have Kan do a tune in February when he is here.

2.) Replace my stock wiring harness with a HALTECH, and have that tuned.

Now, I hear ups and downs... PFC is better blah blah blah, Haltech is better blah blah blah. So I am looking for facts and experience here.

Has anyone used both ECU's and can honestly say which is better to use?

This is my application:

AF61r Turbo
Medium Street Port w/3mm Seals
850/1600cc INjectors
Supra Fuel Pump

Looking to boost 15psi for pump 91, 18psi with 100 octane, and 22 for C16 on track only.

I have friends who use the haltech and are happy, and the same goes for the power FC. I figure I have to spend $1000 to get the PFC to work, so going with a Haltech wouldn't seem unreasonable.

Anyway, please throw me some details on both.

Thanks,

There's really no better or worse between any EMS for that matter. It depends on the personal preference and the tuners ability. I have tune so many different types of EMS that I doesn't matter to me what is better or what. Here're so Pro's and Con's

Pro's

Haltech

Higher resolution 24 x 32 map (768 data points)
More I/O than PFC
pre-defined load points
injector staging (which turns the secondary injectors ON at a user-configurable load point)
More Features (for those who wants to do drag racing)


Power FC

Excellent basemap
Easy to interchange injectors
user configurable load and rpm point
user configurable map sensor
Controls OMP (still debateable)
Easy split timing modification


CON's

Haltech

harder to create a basemap
E6K, A, S still uses dos format
Sensitive to trigger pickup
questionable timing accuracy

Power FC

Less resolution than Haltech
Limited adjustablilities on idle ignition/fuel map
No additional features (compared to haltech)
No additional I/O for other use (unless run with datalogit which from what I heard doesn't work too well)


I think that's about it.
To give you an idea on tuning time, I can tune a PFC in about an hour (low boost to high boost). To do the same on the haltech would take me almost double the time. This is assuming I didn't run into any major issues that need troubleshooting.

hope that helps

 

STEVE!

Going to be at R&R in Feb right? I'm getting on that list, I'll need a tune either way! lol (Dr. Pepper Big Gulps on me) haha

Thanks man, I appreciate your help!

 

Pick the one you can get better (local?) tech support for.
You can't go wrong with that decision...

Pluto, that being said. How would the E6K Compare to the E8 model.

I hear the E8 is a crapload ahead of the E6k - also uses a windows format?

 

The software on the E8 should be the same as the E11 which I have experiences on my 3 rotor FD. It's definately stepping in the right direction compared to the good'o K series.

 

Go E8 if you can afford it.
I just got to play with one, and it's tons better than the E6X.
Full sequential baby!

Alright, now it's between the E8 and E11v2

Is the E11v2 too much for my application? I am still 2 rotor with a AF61r...

I hear the E11 is more for a 3 rotor app....

 

Yeah, E11 is basically an E8 with just more outputs.
No reason to go E11 with a 2 rotor unless you're doing some really funky stuff!

FROM THE GRAVE!!!!!

PFC vs E8 for 600hp.

People say the obvious choice is E8, but... what are all these extensive features that make the haltech that much better? Of course, I am interested in the drag strip... but I don't like the idea of 2-stepping my turbo to the grave =/

 

The most obvious one is 768 data points vs. 400 data points.

You can just do so much more with the haltech with its features (anti-lag, two steps, OMP, idle control, etc....)


Also, if you look at a dyno chart between a haltech vs. PFC, you'll notice haltech has a much smoother dyno curve.
