Link AFM Unit
There has been discussions regarding our AFM unit. Some of what has been written is not correct, so I thought I would put the record straight.
Our unit allows the removal of the Mass Air sensor and turns the system into Speed density. This is a very technical piece, and the calibration is typically beyond most do it yourself types. It was very difficult for us to customer service. We stopped producing them as a generic part, but have decided to produce them as a application specific part. That is, we will provide them alraedy calibrated for the 944 etc. This will remove the prevoius problem of calibrating, but will still allow the end user to modify the fuel map. Link USA did enter into an exclusive arrangement with a company who has agreed to volume purchases giving us reason to produce. This agreement requires them to make this unit available to Trade and retail customers.
Any previous statements regarding non availability, or improper behaviour on behalf of this company are completely false.
If any one is interested in this product, needs further information etc., or where to purchase it, you may contact Link USA @ 949 646 7461.
I hope this clears up any misunderstanding regarding the Link AFM unit and past comments by "Danno" in his posts should be disregarded.

When did you stop producing them as a generic part?

I would buy ONLY from Danno. he has been a great help for a long time and why give the money to somebody that i do not know? I would prefer to give them to a friend.
Is there a reason to buy the same Product from somebody else? any advantange? I don't see any.

Now hold on guys, I think you all are jumping the gun here about what the manufacture is saying (maybe mininterpreting), though maybe it's me doing the same.
What I read here was that the units ARE (or will be upon re-manufacture of the pieces) available to whoever wants to buy them (i.e. - Danno).
The part that concerns me is the "calibration" piece. I thought that the MAP sensor was suppossed to measure AIR, and the measuring of AIR should be the same no matter where you're located, or what car you have, BUT we do not know (as Danno has not stated), whether or not he was using the pre-calibrated piece, or a unit in which he also calibrated himself.
What I'm trying to say is, lets wait and see what Danno's saying about how he's going to get ahold of these kits. It appears to me that the Link-SYS WILL be available to him (for us), so no need for us to get our panties all bunched up, it cuts blood circulation to your vitals.

Isn't speed density a contratiction? It's either speed (MAF) or density (MAP) - not both.
Am I misunderstanding something here?

Yes,
Most MAP based systems use a combination of absolute manifold pressure (density) and throttle position (speed) to calculate fuel values. There are versions that use only throttle position and intake temp only. Mostly for normally aspirated motors.

"Now hold on guys, I think you all are jumping the gun here about what the manufacture is saying (maybe mininterpreting), though maybe it's me doing the same. "
Yes, please calm down and relax. You might be mis-interpreting things as I had done originally and may blow things out of proportion. Link-USA/Performance Developments is the distributor of these AFM-Link boxes and they are in no way a competitor. They were caught in the middle of a tug-of-war battle between us and another tuner and have artfully devised a solution that works for everyone. I truly commend Neil for his understanding and patience in this matter.
Just to expand on Neil's statement on pre-calibrated units; certain 944-specific information will be hard-coded into the unit. Such as the number of cylinders, the TPS, AFM span ranges, MAP-output ranges, and other fixed values. These settings are what have caused them so much tech-support difficulties with end-users.
That said, Travis & I got the unit installed and running in our development car on the Friday night we got it in less than 1 hour on the sidewalk in front of his house using a flashlight and a pair of needle-nose pliers because we couldn't wait for his shop to open up again. These settings aren't rocket-science, but they do require an intimate knowledge of engine-management systems and the specific car you're working on. However, others have been trying to weasel these settings out of us, which leads us to believe that there's not quite enough rocket-scientists to go around, heh, heh...
The important part and real value of the unit, fuel-control will still be adjustable. That's simply because there's so many variations of configurations with turbo-sizing, boost-level, engine-modifications and such, that the flow-correction maps simply cannot be pre-programmed and still be optimal for each and every car.
We will be shipping the kit with our own custom chipset to optimize fuel and ignition for a stock 951 anyway. Then the AFM-Link unit will be used for replacement of the stock AFM and its convoluted plumbing with minimal fuel-adjustments needed because they will be pre-programmed into the chips.
However, I have yet to hear back from the new vendor/retailer as to a time-schedule on when and how many units they can deliver to us.
Stay tuned guys and thanks for all your support!

Pretty much everything needed to do a quick SDS install on 951's is already available (other than the crank magnet). Full base fuel/spark maps are on my site to get you going quickly.
Danno's system is a lot cheaper, since you need some sort of boost control on the SDS unit, where as Danno's system is a piggyback to the stock systems. Both systems should yield the same results.

Seem's whatever you write, you can never get everyone to understand. The AFM units will be available to anyone, Trade or retail. If you are interested in this product, and have been following Dan's comments, please refer your requests for this product to him. Link USA through our exclusive distributor will supply Dan with as many as he requires.
As of this morning, we have 22 finished and are presently working towards having 30 completed shortly. Delivery of the 22 can be next week if required.
