Porsche 944 DIY Tune for INSTANT Horsepower! (Bosch MAF Tune) 

You are a very bright and articulate kid! And please take no offense in the word “kid”.....I’m 65, retired military and retired law enforcement.....proud owner since 2006 of a 90 944s2 cab. Your willingness....and yes, some courage....to work on your car - to experiment - is very impressive! And should encourage other 944 owners to do the same. You have the tenacity, and intelligence, that used to impress me of my young Navy Sailors and young Federal Officers--which frankly, goes far in decreasing my concern for “tomorrow”. I firmly believe that you will do very well “in life”! This video was both entertaining AND educational. Bravo-Zulu, young man.....well played! Very well played!

This is the video that everyone should be watching if they need to adjust their AFM. My 944 was running rich, so I leaned it out turning it the other direction. Throttle response, idle and the over all smell of the emissions cleaned right up! Your video was thorough and brilliant. There’s some other jokers that did videos on this. I am glad I found yours!

Young man, you impress the hell out of me! You are most definitely wise beyond your years! I own a 1990 944S2 Cabriolet….I bought it as a gift to me when I turned 50 the same year I was promoted to O6 (Captain) in the Navy. As I live in New England, she is stored for five months out of the year. I’m at that stage in my life that I have neither the patience, tools or a spacious garage in which to work….and I have an income that permits me paying to have my maintenance performed by a vintage Porsche mechanic that restores old cars. Still, there was a time that I did my own work….and your video will help many owners of these cars….keep these cars on the road! So Bravo-Zulu….we’ll done. Oh! By the way….I think those 944s pre-1985….have the coolest looking gauges clusters! I don’t know what your intentions in life are…..and obviously I don’t know you from Adam….but I think you have a great future ahead of you….and frankly, I’m proud of you. I wish you only the best….and a couple times, you made me laugh, while teaching me something! Best of luck, to you and in all that you do!

I bought a chip from Race Pro's that basically did this perfectly without messing with the MAF sensor. Then upgraded my gas to plus and now she's a small beast!

Wow... that is a lot simpler than I thought it would be...

I think it really works! Engine is working smoothly and acceleration is little better. On the occasion I cleaned throttle and setup low rounds. Another modification and great satisfaction when working with it. Thx a lot :)

It's very interesting. I will try this on my 944 soon and share my result. Thx for video Porsche-bro.

What a very informative and educational video! I'm slowly working on my 944S and this video is very helpful for sure. Subscribing.

You could also replace the Porsche emblem on the nose with a sticker(Porsche, preferably). In addition to the obvious weight and aero benefits it will give added status points. Just like a GT3 RS!

Awesome useful and very well done. Thank you

Do not even think about doing this unless you have a wideband O2 gauge, you can play about with where the wiper sits on the track at rest and the tension to very slightly alter the enrichment curve but like I said, without an O2 gauge you have no idea whether the end result is better, FYI, decreasing spring tension runs richer, slightly more at low rpm's, to run richer at high rpm's tighten spring but advance arm, saying all this, there is a factory adjustment which can be done externally, the procedure is covered ion the workshop manual

The best mod to put power to the ground is smaller rims

I think the previous owner of my 944 tried doing this and went over board.. does anyone know how to get it back to the oem settings?

should be noted that this should only be adjusted simultaneously with the DME o n a dyno with lambda .

The only real problem here is you keep referring to this system as a MAF, when it simply isn't. A MAF measures air flow with a heated element which passing air will cool. The 'barn door' on the afm is literally pushed open by air entering the intake. As you might guess, an AFM is inherently restrictive, which is why one of the great upgrades you can get for a 944 is a MAF conversion.

Doesn’t actually make it run richer it just lessens attention on the spring so it’s more responsive or less responsive. If you make it less enough, it could get leaner.

Where did you purchase the round throttle pulley to replace the extended arm version ?

Could I use this same technique in reveres if my cars running a bit rich ?

Beats!

Where did that shift knob and boot come from? Is that mentioned in any of your other videos?

How exactly did you get it to rotate counter clockwise??

I have the same dealer two tone car

I had one time bmw 2.0 v6 bosch afm on 944 for fun. Now days i have it deleted and have moved to use VEMS and wasted spark.

When looking at the sprocket from above, are you advancing it one tooth clockwise or counter clockwise?

take those crosses off the headlights you new kids are so cringe bro

An options for an upgrade

Don’t mess with that, you change the mixture air/gasoline, you ended up blowing your engine. It’s simple, DO NOT DO IT

Is it different with a new modle like a 86

1 tooth?

First! Give me a cookie I deserve it.

I don't know about this.

You sold the car.

DO NOT DO THIS MOD!!! This is a really bad idea and no doubt part of why you killed the car. You're definitely not a mechanic and have proven you have no clue what you're doing. Thank god you eventually sold the car and are no longer giving idiotic advice to 944 owners. I repeat DO NOT DO THIS MOD if you have a 944 unless you want to kill it too
