I have no sensors on the Air Box. Just a thermo switch for the throttle body heater. There is a temperature sensor on the bottom of the Intake Manifold - I know that this one will trigger a light since I once forgot to connect it. There is another sensor on the passenger's side brake duct. It has nothing to do with the OCBC - that one's on the Driver's Side (I again forgot to attach it once :-)). I've heard that the passenger side one is for DME ambient temps but I'm not sure. Anyway, my car is a 4/94 built.

And nowhere near as expensive as a Porsche unit. You'll probably get the best 1/4 mile time with a 2900-3200RPM launch, at least with street tires. Just drop the clutch. If you start to slip the clutch on the launch it will usually slip all the way through the gear, causing excessive wear and high times. A good launch shouldn't be all that bad. Just look at it this way.. all us crazy autocrossers do it 6 times an event. I learned most of this by trial and error. Once I was armed with a G-tech and cartest it was much less painful. My car has 50k on the origional clutch, about 8k with a turbo and a lead foot. -Matt --- Milotaks1@aol.com wrote: > Date: Sat, 9 Sep 2000 11:41:52 EDT > From: Milotaks1@aol.com > Subject: Issues at the track > > Yesterday I went up to the local dragstrip, > Moroso, for a simple night of > test and tune, which turned out into a nightmare. > First pass I ran 14.2 > which is pretty good for my car and on the second > pass there were problems. > I usually launch at about 3k, but this time I decide > to do a "super" launch > and I rode the gas up to 6-7k with out being off the > clutch.

#10. Re: [E36M3] AIT Sensor (again) [and again] - from LoweSeaton@aol.com

Date: Sun, 10 Sep 2000 00:54:17 EDT From: LoweSeaton@aol.com Subject: Re: [E36M3] AIT Sensor (again) [and again] I'm with Paul on this one. I think we are splitting hairs. :-) My '95 M3 has a "thingamajig" stuck in the air box. I don't know for sure what it does but it is an impressive looking thing. It has two good sized hoses running to it. I assume it measures the incoming air temperature based on its location. Right? Anyway, I'm not William Webster but I'd say a "thingamajig" that measures incoming air temperature and controls another device is an "air temperature sensor." Oh all right. It is "the incoming air temperature thermo couple that controls coolant flow to the throttle body to ensure that the engine runs smooth during cold weather start ups." Whew! Or "air temperature sensor" for short. Matt says the air temperature sensor for the DME is located under the intake manifold. Sounds good to me. How many total air temperature sensors are there on the M3? As for the air temperature sensors in the brake ducts? Yep, the driver's side one is the read out for the OBC. If you disconnect it or loose it in an impact, your OBC will read -37 or something like that. And I think the silver dollar looking round sensor in the passenger side brake duct controls the heated door locks, heated windshield washer nozzles, and heated outside mirrors. I think all the E36 M3's except for maybe some of the very early models have heated door locks and mirrors. And for some reason I think the '95 M3 does NOT have heated washer nozzles. I think heated washers came in '96?
