Anyone still using an AFMlink?

[Pettybird]

I got the one offered for free on the recycler here, and I've since picked up the tuning module. I'm pretty smart, but I've never messed with something like this. Is it kinda-sorta intuitive or am I just setting myself up for headaches untold?

I know it's an older technology, but I have a grand total of $60 wrapped up in it...seemed like it would be worth a shot. I'm not deviating very far from stock, so I'm not looking to tune something out of left field.

Thanks

I've got one... It actually came with my car. I believe you need need a set of chips also to use the link, not any set but map base ones.

IF you don't have the instructions... here it is.

Would one of those work, along with the ostrich2 that I already have, for a MAP conversion (from my current MAF setup)? I'd LOVE to have a 100% clean intake run, from cone filter to compressor inlet.

I read the instructions, and it looks like you set it up in parallel so that it can "learn" what the AFM does at various vacuum levels and RPM's. I'm not certain, though. I may just try it in the spring and see if I can get it close enough.

There's actually no learning. You can use in parallel with the stock system to do datalogging of boost, AFM-voltage, TPS-position, O2-sensor output, etc. But all the adjustments have to be manually entered. Don't forget to hit the SAVE button or else all those adjustments disappear when you turn off the power. Although that's a handy feature for dyno-tuning. If you've botched a run with non-effective adjustments, just turn off the power and it goes back to the previously-saved settings.

The MAP-specific chips adds additional fuel to go with increased boost. The output MAP airflow signal scales across the same 0-4.6v range as the stock AFM and to prevent running into the edge of the map prematurely, the chips have more fuel at the same data-cells than stock. The path through the 3D map is also different than with an AFM, so certain areas are rotated relative to the AFM chips. For example, full-throttle at 2000rpms results in different output-voltages for the AFM versus MAP and the look-up point on the chips will be different. This is the difference between flow-vs-RPM and load-vs-RPM mapping.

Send me a pm/email and I'll send you the 951-specific instructions. Out of the box, they didn't work well. Needed some specific settings to work. I also had customized firmware made for the 951's AFM voltage-curve as well as the 3.75v TPS. If you have the generic span & alignment box, it can be programmed to work as well.

I don't see why it wouldn't work. only down side is the slight lag in responce. motronic and the link dont like eachother like cats and dogs i guess..

I used one for years with pretty good sucess. Lots of people had stumble issues off idle. I was able to overcome most of those problems. I really liked on my car with a 27-6 turbo.
