#2. Euro HFM Cold Air Intake Impressions and Questions - from Frank & Kirsten
Top
Date: Wed, 20 Aug 2003 20:10:54 -0700 From: "Frank & Kirsten" <FranKirsten@msn.com> Subject: Euro HFM Cold Air Intake Impressions and Questions I've cross-posted this message because a few people from the different digests have given me information or sold me a part related to my fabricating my own Euro HFM CAI setup. So, I have some impressions, information and a couple of questions. First the impression from driving this new setup is everything positive that I have heard from fellow M3 enthusiasts. The power gain is nice and the sound is very appealing. Normal sound until you stomp the pedal, and then it really tells you that the car is breathing. I had a standard hop-up JC chip with no other mods, so the jump to this setup was not the total wow factor some have experienced, but I am very happy with it. It is quite impressive to feel the temperature difference between touching the intake head shield and say the cruise control or fender well area behind the shield. While sourcing parts for this setup, I bought a JC Euro HFM chip off a fellow lister. This chip was dated 1998 and this is an important fact because the JC chip I was using is dated 2000 and was in the car when I purchased it. So, I swapped the chips and the car would not start. I thought maybe, possibly, I reversed the HFM chip, but still no start for the car. So, I put the original in and it started right up. I thought maybe I fried the HFM chip by running it backwards. So, I called Turner Motorsports and a fellow named Drew set me straight. He informed me that you can not fry the chip by reversing it, and proceeded to ask me if I had the encrypted board for the HFM chip. To make a long story short, the chip that was in my car when I bought it has a little piggy-back encryption board that goes along with the chip, and the chip I bought for the HFM set up did not use one. So, when I removed the encryption board, the HFM chip started right up and the car has been running great. I want to tell you that Drew and Turner did an excellent job explaining what the problem could be, and I really appreciate the information he shared. For many businesses, it would be easy to say you are screwed and sell you a new chip. I'm very glad Turner Motorsports has excellent customer sales and service. So, if you are buying a used chip from someone, be aware that it may OR may not require an encryption board for it to work in the DME. Oh yeah, all those little tabs that hold the DME cover broke. That sucked, but I was told that they really are not necessary and that you can not get a replacement cover. So, I guess I'm not going to worry about that since it seem pretty well sealed up in the fire-wall. My question is what have you people running CAI setups done with the air temperature sensor that valves coolant to the throttle body(it used to reside in the stock air box)? Bypassed the valve, or reinstalled on the other side of the heat shield? I took it off and used a barb to connect the two coolant lines and plugged up the ports on the throttle body. Did I do a no, no? What about that damn carbon canister that is used for the venting of fuel vapors? What could be the negatives if that 'fell off' and the throttle body port was just plugged up (hypothetically speaking)? I went with the ITG filter, is the regular maintenance cycle for cleaning this about the same as an oil change(approx 4K miles)? Thanks for all the information and help on this and many other topics.

#3. Electrical question re. Air Flow Meter - from BOOM,BILL (HP-Roseville,ex1)

Date: Wed, 20 Aug 2003 20:31:15 -0700 From: "BOOM,BILL (HP-Roseville,ex1)" <bill.boom@hp.com> Subject: Electrical question re. Air Flow Meter Sorry for the length... I have a Euro/540i Air Flow Meter installed on my car. Not sure how the Euro AFM kits out there handle the issue of connecting the Euro AFM electrically (since the connector on the Euro is different than on the stock), but the way it was done on my car is there are 4 wires coming out of the connector on the Euro AFM with pins on the other end, which kind of just rest in the holes in the stock connector (which ordinarily would be connected to the stock AFM) coming from the wiring harness, with electrical tape wrapped around it. Not very clean, and I want to fix that. I could just cut off the stock connector on the wiring harness side and connect the ends of the wires coming out of the Euro AFM directly into the ends of the wires coming out of the wiring harness, but then I'd lose the ability to easily go back to the stock AFM if I wanted to. Another option is to find a non-functioning stock AFM for cheap, cut the connector off of it, and connect the ends of the wires from the Euro AFM to the back side of the connector. Then I could plug that connector into the wiring harness side connector... in essence, I'd have a bridge between the stock connector from the wiring harness and the Euro AFM, which would be removed if I wanted to put the stock AFM back in. But what I'd really like to do is just splice the wires coming from the Euro AFM into the wires coming from the wiring harness *upstream* of (i.e., a few inches behind) the stock connector. So I'd then have the wires coming out of the wiring harness, then each of the 4 wires would fork, with one side going to the stock connector as it is now, and the other side going to the Euro AFM connector. Obviously, only one of the two connectors would be plugged into an AFM at any time, and the other would be hanging in the breeze. So the question is: Anything wrong (electrically or otherwise) with doing that splice? - Bill

Date: Thu, 21 Aug 2003 00:19:35 -0400 From: ChuckBrazeau@aol.com Subject: Re: [E36M3] Euro HFM Cold Air Intake Impressions and Questions I had that same question when i was looking into building my own in-the-bumper style CAI... what to do with that sensor? I'm not sure exactly how it's supposed to work, but at normal room temperature the coolant valve is open (allowing coolant to flow through the throttle body). I tried freezing it in my freezer to see if cold conditions make it close... nope. Then i heated the sensor side over an open flame on my stove, and as it got hot it slowly closed. So... apparently it closes off the coolant flow to the throttle body when the ambient air temperature inside the airbox is extremely hot (when would that be?). I was reading through the CAI installation instructions on Benfer Performance's website to see if they mentioned anything about this sensor, and they stated that you could just zip tie it to the bottom of the HFM with the long zip tie that they provide (simple enough). I chose to by-pass the sensor completely (leaving coolant flowing to the throttle body all the time like the sensor/valve would during normal temps) for a cleaner install, since it would most likely be cooler than open flame temps in the intake track of the CAI, and since there's no electrical connection that would send a false reading to the ECU. I haven't had any problems so far, but i'd also like to know if this can be safely by-passed, and if so, should coolant be left flowing through the TB or should it be blocked off?

Date: Thu, 21 Aug 2003 01:11:43 -0400 From: HyperM3@aol.com Subject: Re: Hood shock ?s & Needed I recently had this happen to my car, although it was only one shock. Its hard to tell if its both shocks because the hood is amazingly too heavy for one shock to hold up. This happened w/out warning as well. Just came to see 'goo' oozing down the side of my drivers side hood strut when i opened it one day. The passenger side was fine. I ended up getting a new strut from www.zionsvilleautosport.com and the price including shipping was $26. Hope this helps.

Date: Thu, 21 Aug 2003 08:19:26 -0400 From: "NickG" <nick@tech-nick.net> Subject: Re: [E36M3] Electrical question re. Air Flow Meter Bill, You don't mention what year car you have. If it's a 95, then the Euro/540 HFM does have the same electrical connector as the stock HFM and just plugs right in. If you have a 96+, then yes, the electrical connector is different. Contact Eurosport in Utah, as they'll probably have a jumper harness. But keep in mind that whatever year car you have, you have to have the correct software in the DME to make the engine run properly with the different HFM.
