I'm looking hard at purchasing a PFS Purple piggyback ECU. There seem to be a lot of these things running around out there, but I see that there appears to be at least of couple of different of the little hand-held controller units. One has the display screen above the keypad, one has the display screen off to one side.
Any input on this would be appreciated, as would general information on overall experiences.

Thanks!

 

Dont waste the money, get a Power FC.

power FC owns... read up on it, you wont be dissapointed.

 

^^^^what he said^^^^

But with the Power FC I lose my automatic tranny's cool hold function, correct?

The Power FC is a full stand alone (unless I am mistaken) and I just want a piggyback ECU.

I've done quite a bit of research into "Peter's Purple Motor Eaters" over the last couple of weeks, and quite frankly I don't think there is a better alternative that suits my needs. Let alone the fact that these $900 ECUs can be had for a third of that (or less) these days. One thing that strikes me is that the PFS unit seemed to open to wide acclaim when it debuted, with the main problem seeming to be that people were demanding ungodly hp output whilst having their cars tuned for race gas, and then crying when pump gas was grenading their engines. I realize from all my reading that there was an entire Peter Farrell saga that garnered intense Internet interest, along with the accompanying rumor, innuendo, and gossip. But nonetheless, there are scores of people that stand by PFS devoutly.

 

Baja, I ran an 11.69 with the PFC unit, stock sequential twins. (And I just so happen to have one for sale. Newest software, new harness, & with the last version if the iInteracq software that gives you adjustable fuel, timing and boost maps.)

Stuff on the software here:

I'm in the midst of going single, which the PFS unit is not good for. So long as you are staying with the twins and so long as you don't run a midpipe, the PFS piggyback is a fine machine. And I also pass emissions with a high flow cat by dropping down to map number 1, basically stock maps, with the flick of a ****.

Map 2 is my street setting at 12 lbs and map 3 is all the boost the unit can make on race gas only, around 17-18.

"Peter's Motor Eater" does not eat motors. I have run it since 1995. Do not run a midpipe, stick with a high flow cat to control spikes, and you will be a happy camper. Tuning, tuning, tuning.

And the whole internet battle had nothing to do with the PMS.

 

^ tcb, thanks for the info, that is good to know. Obviously you have had extremely good luck with yours and are satisfied. Your experience mirrors a lot of others I have read about.

 

And I add, a 30 minute install at most. No fuss, no muss. If you get ready to actually buy, PM me. Extra special pricing for right-wingers.

 

pm'd you.

lol.....I hope that is a discount for us crazy right-wing hawks!

 

But of course.

 

Bajaman,

I don't know much about upgraded ECUs on automatic fds but I don't suggest using PFS purple box. I had one back in 2001.. and 2 months after talking to PFS and the guy who made it, I decided to sell it. I don't know how much better it has gotten since 2001, but if I recall, resolution was pretty bad and like any other aftermarket ecu's, you need to tune it yourself or someone needs to tune it. I just think its not that great of an ECU..

Also, I think I read it somewhere that you could use PowerFC. I would do a search for PFC and automatic.. I'm pretty sure I read something about that..

Matter of fact, I had a discussion about this.. and someone proved to me that people in fact used PFC to control their automatic tranny.. I'd always thought that it wasn't possible..

Good luck!

 

I'd seemed to remember something similar and I searched using keywords 'auto', automatic transmission, PFC, Power FC....all to no avail. It seemed like a senior Forum member/someone who knew their business had posted the information....it drove me nuts trying to find it!
Sigh....

 

With the Interacq software, 13 columns by 9 rows ain't bad. The PFC is obviously a more modern unit and is a standalone and in the limit, capable of more fine tuning. Costs more too.

But I will stick with what I said above: how many sequential twin turbo cars with a cat and stock injectors go 11.6-11.8? Rikki also ran an 11.7 on one of the hottest, muggiest days of summer, also using the same unit, but non-sequential.

A lot of this stuff gets overblown. The factory ecu has a hell of a lot of R&D behind it and the piggyback concept is pretty cost effective when you factor in the lack of hassle. So is the Pettit unit, though not adjustable.

And keep in mind those times of mine are with just the medium stock mount PFS intercooler and PFS cold air intake, also a quick, hassle free, one hour install.

I'm a big fan of the PFS upgrade path. They are not intended to transform the car into a 10 second car, just to improve it. You can go fast with any of the ecus out there. The PFS unit does what it was intended to do, just make the sequential or non-sequential car quicker without busting your ***** to get it all to work.

 

tcb - did you get my pm yet?

 

Yeah. I'm up to my neck in other stuff right now. I just need to check the going rate.

 

Not to muddy the waters but I ran my corrected 10.98 on a PFS gold box .

Yeah, but that's you. All honor to the pioneer.
