16valver

Howdy Rennlist,

As mentioned, the car in question is a 1987 944S. Unfortunately it still retains the archaic 'barn door' AFM. Normally I'd just do what everyone else does and hope it keeps working marginally well as it has for the past 28 years.

The twist is that I have a 968 MAF sitting on the bench, as well as the wiring harness. In addition, I would absolutely not be opposed to a performance chip of some sort that would hopefully give the stock motor a little more modern feel (and hopefully pick up).

I know from some searching around, that the 968 MAF and 944S computer likely won't play well together. So, is there a solution that will encompass both of these ideas? Perhaps the chip making community has the ability to custom bake something that will read the MAF's outputs?

I could be completely off my rocker but I figured I'd ask

Thanks all!

I would love to see some MAF solution for the 944S. Mine still has the barn door as well, and to make it worse the PO, when converting to a conical filter, actually took a saw to the plastic mounting area where the original air box tube would normally mount to. So it's kind of a hopeless mess at this point.

Joshua at Rouge Tuning (http://roguetuning.com/home_-_news) was working on a MAF and software for the 16V motors, but he is a one man shop and has been very busy with other things for some time now.

I'm hoping he finds time again one day!

16 Valver,
Have you tried John Vitesse.

Hopefully soon! I beta tested that setup on my S and it was quite nice.

Haha, I thought this thread died a slow painful death! Forgot about it.

Yikes!

I'm hoping so too. I've been eagerly waiting the 16v version of his stuff for a LONG time.

I have not. Perhaps I should.

I hate you so much! Man...this needs to happen soon...haha.

Are you opposed to migrating to a standalone setup? It's 3rd party, but so is a MAF. Lots of doors opened and you no longer have to report to Bosch. You can run whatever you can make work (I say that as I'm running a MAF made for the 944 piggybacking on Bosch EFI so I'm one of the cheerleaders sitting on the bench).

Only because of the cost, but you're quite right. In terms of waking the motor up and making it more usable, modern tuning and sensor hardware go a long way. I have an engine build happing right now that involves VarioCam. Once completed I will most certainly want a stand alone so I can play with all the cool timing and valve goodies that VarioCam offers

For my motor at the moment (orginal S unit) the piggyback intrigues me... Any more info on that?

I may take a stab at the Megasquirt DIYPNP option, since they have one that fits the S DME connector. See here: https://www.diyautotune.com/diypnp/models.html
