Anybody heard ofhttp://www.perfectpower.com/products/prs.asp
Is it any good?
I was considering going with SDS but then I found this system
and I think it looks kind of intersting and the best thing about it for me would
be that the Canadian distributor for it is only 5 miles from my house and
they have a dyno.
I would realy like the KitCarlson but I am running out of time
if I want the car back on the road this spring.
I have to make a decision very soon.
What do you EFI guys think of this system?
I'm pretty sure Ben M. (airsix) is running that system on his turbocharged 1.7
almost all of the available EFIs are similar that are within the same basic price range...buying from a local rep. might be advantagous when it comes to tuning.....
I think they would have done better in the US if the original importer was not such an idiot (a group buy was set up a few years ago directly from the manufacture and the new US importer/distributor totally screwed things up.....this got out among potential buyers and we looked and bought other EFI products instead)
I have the SMT6 piggyback for my 944 turbo. I haven't installed it yet so I really have no feedback to give. As much as I like the guys at SDS their system is really archaic for the price that you pay. It's priced around $2200 canadian when all said and done and for that kind of money you could get a Haltech, Autronic, etc. that data logs and has many more features. Just my $0.02
P.S. Don't get me wrong...I really do like the guys at SDS as they are in Calgary (where I am at) and many club racers use their product. In my opinion it's used more for the technical support these guys give than the actual capabilities of their product.
Ray: Look into the Haltech E6K or E6X. I'm sure it would do everything you need (and more) and will cost around $1300 with all the parts (wiring harness, etc.)
Yes indeed, I am running EFI/ignition from Perfect Power. The fact that you are close to a rep with a shop is awesome! That will be a very important benefit. My local rep was... in South Africa. Having someone local would have been killer. Anyway, they are good honest people (Klaus and his kids run things. Klaus is a German inmigrant) They really bent over backwards to help me out and fix the issues with the moron US distributor (he's not a distributor any more). I'm running the MIC3 which is an old design and the grand-daddy of the system you're looking at. I'm very happy with my ECU. It does everything I need and more. The software and physical construction are not as refined as say a MOTRONIC, but at pennies on the dollar it works awesome. I got laptop-tunable digital injection and ignition running and on the road for a total cost of about $500. It's hard to complain about that. Digital EFI/ignition for less money than carbs. I'll still be laughing about that one when I'm on my death bed.

The local guy here has a brand new in the box (2003 model) PRS 4 that
he will sell me for $700. Which includes the wiring harnesses.
I thought that sounded pretty reasonable.
I figure I could round up the sensors and pigtails for another couple hundred.

I thought it came with the sensors. Should have a TPS, air-temp sensor & coolant temp sensor. MAP sensor is built in. The TPS they use is just a potentiometer (at least it used to be). You should only have to provide the injectors, fuel pump, relays, and ignition parts. -Ben M. |
I have a PRS-4 (not yet installed) It comes with the Brain, wiring harness. (does not come with any sensors) The Serial cable and developer software package were extra. Let me know if you want a copy of the manuals on CD.
It was the most for the $$$ at the time I bought it.
I looked at this recently, and it looks like they raised the price significantly over what Ben paid, but even so $700 with harness but no sensors is still not a bad price. The SDS system is about $1200 for pretty much the same thing (includes sensors and a coil pack worth maybe $150 all told). The KitCarlson is $1400. I've seen the Autronic priced at about $1200, but I don't know what it comes with. Dunno what a Haltech runs. Pretty sure the Electromotive TEC3 is over $2K.
We sell the Haltech E6X for $1284 USD
there are lots of great options for engine management nowadays

Ok, about the sensors... I just went and looked. The new PRS is SWEET! You can user-configure the sensor signal interpretation. Basically that means you can use whatever sensors you want. Cool. Want to use a head-temp sensor instead of a coolant temp sensor? Just program in the signal range and go. Neat stuff.

big deal...you can do that already with the Megasquirt |

as for Perfect Power, I couldn't find any US based websites for it.....someone must have really screwed things up for them... |

Yes, but you can't do it through the tuning interface can you? I thought you had to actually hack the firmware and reflash the chip. -Ben M. |

The PRS system can run closed loop, they claim it can self tune (we'll have to see about that) Don't know about the wideband controller part, I don't think it's built in.
I bought an LM-1 to help with the tuning when I get this thing togeher.

The LM-1 is my Fairy Godmother. After I was reduced to my last nerv and ready to set the car on fire, cackling wildly as it burned in front of me I got the LM-1 and in minutes my 914 went from "runs like crap except at WOT" to "quite nearly perfect" in about 20 minutes. Money well spent.*
-Ben M.
*I'm referring to tuning an ECU from scratch. I'm not saying to get an LM-1 if you have stock injection. Save your money.
Does anyone know if the Haltech requires a crank sensor to control spark? or can it use a signal from the dizzy?
What about Perfect Power?
Tommy,
I didnt forget your pm, just havent repled yet. The haltechs need a crank sensor, even with the dist. Though you may be able to get a dual synch dist from accel, Not sure if they make one for a 914, the do make a 911 dist though.
after dinner Ill shoot you a pm
I'm sure you can use the Haltech with a dizzy sensor. Look at how Mueller put optical sensors in a Mallory dizzy to emulate the D-jet trigger points. You can do anything if you want to. Perfect power will run off just about any triggering setup you want to try. I ran mine off of mechanical points one day just to see if I could. I also ran it off a magnetic pickup in the dizzy (which I took out of a Mitsubishi at the junk yard). Then I ran it for about a year using a Crane optical sensor and shutter-wheel. Currently I'm using a hall sensor on the crank (which has been the best method so far).That's one of the cool things about these digital ECU's - you can use your imagination and come up with lots of different ways to accomplish the task.
-Ben M.
mah bad, yea you can use a distributor for the signal to the ecu, we did an SC with a similar set up. Its just a matter of telling the software how many pulses it will see per engine cycle.
Just to throw another one out there that I was looking at, what about the Micro Tech??? anyone using this unit? www.microtechefi.com
