You may want to wait a few weeks to send the dog sleds down, it's supposed to be 60 here this weekend.

Well it's definately the MAF. I can take it off and reinstall the AFM and everything is fine. I put the MAF back on and drive 10 minutes and it won't start for an hour. I'm through with it. I just stuck the AFM on for good. I will be taking it in that way for a dyno tune and some numbers. I can't deal with problems. I'll just wait until I get the complete kit and start over. Unfortunately it probably won't be until after the first of the year.

So, let me get this straight..... You installed the MAF without tuning it and expect it to run properly? You're kidding, right? Your are running INCREDIBLY lean.

My guess would be that this MAF came "pre-programmed" from this whackjob vendor and it too has proven to be a piece of crap. Probably nothing wrong with the unit itself, just the moron that prgrammed it. I'm amazed it even started for you Steve.:rolleyes:

It came "preprogrammed" but unfortunately w/o a wiring diagram and with a bootleg set of software. The software won't load so it's kind of tough to get it working properly. The car actually ran fairly well until it develpoed the hot start issue. If I put the stock AFM on it runs fine. I actually got the low end performance to be fairly good. It definately needs the dyno tuning. I talked to the guys @ Lindsey and they were not much help and Professional Mass Airflow Systems who made it are not any help either. I am going to send it to a guy in Norway who paid for one from the same vendor and never received it. He seems like a decent fellow and essentially has zero recourse here in the states. I am about ready to just really tune mine and leave it alone and go out and buy something else. I like the way it handles and I'm just tired of all the soad opera stuff. I really liked my last 911 so I may just pick up another 84-86 Carrera and keep them both. Hopefully some day with the help of our legal system I will recover the funds that are gone. I'm just tired of emails making me out to be the bad guy here and blasting me for not being trusting enough, refund checks being lost in the mail, etc. 9 months just seems long enough to get jerked around. After that period of time it's pretty obvious nothing is going to happen w/o intervention.
I have just been too patient.

Steve

my guess would be that the hot start issues are due to a lean condition. sorry if i came off sounding like an ass. i did realize you were told it was "pre-programmed". If it is a MAF from PMAS (which more than likely it is), it would have been pre-programmed for a 944 turbo. PMAS is the company that Lindsey Racing and Vitesse Racing buy their MAFs. Low end should be exactly the same for a 944 and 951. The only changes would be when the turbo starts to spool up, you'll need more air and since it was probably programmed for a 951 it is giving you a really lean situation.

Don't give up on the project. I'm working on a MAF conversion for my 944S. I'm using a Lindsey Racing ST1 MAF. Which is an 85mm MAF meter from PMAS. But, I will be using a chip that will have an AFM to MAF transfer function written into it. But their will be tuning to get the chip perfect. But it'll be worth it in the end.

I'm just really frustrated right now. I know enough to get myself in trouble with this stuff. I definately do not, and I repeat, do not have the knowledge to go making custom chips etc. I just want a cool good running car. I would never have done anything to this one except sell it but for the fact we are the original owners and it was the first nice car we could afford. I probably should have left it alone and just bought another M3. The experience I have had with money going away on the SC has really left a bad taste in my mouth for the whole aftermarket community. The whole thing was really exciting to me and then to realize it was never going to happen is really a downer, not to mention my wife's attitude about me being "too trusting". If and when I do the SC it will be with someone that can give me maybe not a turnkey deal but at least a cohesive package I can bolt on and take to have tuned properly. That was the alure of the one I "purchased". I have spent a lot of money getting the car ready for the additional power and will probably do something at some point. I'm just tired of all of it right now.

Wow steve, I've been out of town all last week, and it seems I missed alot. How is that MAF wired in? I have a similar hot start problem, but I've only noticed it after washing my car, so I figured there was moisture on a connection somewhere. It seems to drive OK, but doesn't want to idle. I'd attributed this to the factory DME's cold-start fuel enrichment making the whole thing too rich. It doesn't do it if I just turn the car off and re-start it, but it will if the car is off for a few minutes. I'll be the first to admit that the porsche 944 aftermarket is a pain. I've had countless people look at me like a puppy-dog with their heads cocked and eyebrows raised in a state of confusion the moment I say "its for a Porsche 944".

I want very badly to do an LS1 swap, but want to use a turbo for the taller gears and tranny cooler.

That is exactly how mine has reacted to starting. It will fire off immediately within 4-5 minutes then not start again for at least an hour. It fires and dies. Idle is fine. right @ 900 RPM. I totally fu..p up when I did not do the LS1 last year. I had negotiated with Renegade to pick mine up and do a turn key for me to pick up in Vegas. $18K for everything to include 1 way shipping. I planned a trip there w/ my wife to pick it up and fly her back. I would be one w/ the car for a 3-4 day drive through Colorado, stop in and see a buddy that lives in Aspen, you get the picture. I shoulda woulda coulda. I got sidetracked with the SC thing. I also was a bit apprehensive about no power brakes and putting that kind of horsepower to an older VW Rabbit suspended car. Oh well, I should have done my homework!!!!!!!!!!!!!!!!!!!

Steve

you dont *have* to lose the power brakes when doing the ls1 swap.. i've seen swaps where guys can still fit the brake booster in there..

how did you pay, steve? money order? paypal? is there no means of getting your money back from whatever payment method you used?

hey Steve.. just got your last PM.. that's bloody hilarious... the polar bears living in my back yard are still laughing.

Yeah all of us cousins that are having relationships here in the Missouri Ozarks and running around with a big piece of straw sticking out of our mouth even find some humor in it.

Steve

Well I got bored last night after Mrs 944 went to bed so I decided to rectify the poor instrument lighting. I took the speedo and the tach out and took them apart. I sprayed the inside of the guages w/ chrome spray bomb paint and put in new bulbs from Porsche. The difference is amazing. They look almost like reverse lighting with the white faces I have on them For the first time in 22 years I had to actually dim them. Total cost:

(4) bulbs @ .85 ea from Porsche
(1) can chrome paint $3.99

I drove out to visit my father-in-law @ the farm this afternoon which is maybe an hour from home and with the 45 degree weather, top off, heater on, the car really runs good. I took the rest of the MAF stuff off and pulled out the boost guage and the ridiculous moto-meter air / fuel light show. I have a kind offer for a replacement center guage console and I am going back to a white VDO clock and a cig lighter for my cell phone. The way the car runs now I am just going to dyno tune it and use it.

My MAF kit is being boxed and sent to Norway no charge to another guy who did not receive his product. Hopefully he will be able to sort it out. I am sure it's just me and he seems pretty much up to speed.

Steve

Quick Thanks
 

Nemesis:

Thanks a ton for the console. I really like the black look w/o the silver, so much so that I removed the silver from the rest of the interior pieces w/ lacquer thinner. I really like the contrast w/ the white gauges. I also found a Blaupunkt CD player for $80 on Ebay and got the SONY out. The SONY worked fine it just looked weird.

From downunder here in Oz your tacho looks different :)

in north america, our numbers are written with a 90 degree twist CW... this helps differentiate between our math and ROW math. ;)

For some reason I always liked the tach to be straight up @ redline, something about it being more fun w/ high RPM.

Steve

I just fixed something that was driving me crazy. My alternator light has been on dim, especially w/ the lights on. In addition it has been cranking slow. Today it did'nt start for the first time in 22 years, I got stranded. After looking closely at the battery connections I realized that the battery cable was wasted. I got it to start and came home to the garage and then took the Durango to Auto Zone and picked up a 2ga X 72" starter cable and a couple brass battery terminals. It took a few minutes, maybe an hour, after getting the car up on blocks to take out the old cable and reinstall a new one. After getting it done the car cranked like never before, lights are bright, no warning light. I was getting ready to buy an alternator but after looking at the wire close (it was green) it is amazing it ever worked. While doing it I also redid the grounds and used a good dielectric on everything. I guess that the simple things should be checked first.

Steve

i just rebuilt my battery terminals... they look quite good now... but now I'm wishing i replaced the entire cable (battery to starter) because my alternator light goes on extremely dim (you really have to look at it at night) if i'm driving with my headlights on...

is the wire attached on the starter via just a regular washer connection?
