BMW arent that dumb to release the M44 with a weaker engine than the M42 .. the M44 is supposed to the Evolution of the M42 just like the M40 then came the M42... ! __________________ -----tEso----- ..::bmw E36/5 316i ...Hamann 17" HM2 Rims.....K&N superflow filter....Hamann E36 Exhaust.....Mtech body kit with a Rieger M E46 bumper.....E46 M original Electrical folding up mirriors....

It is fun, but seemed like I had to work the hell out of it to get power (Clutch is probably reaching end of life too). Once I added up the cost of adding all the Sport body stuff and Seats that I wanted, I decided to just by a Sport and found a 97 Sport (120,000 miles). Now the question. The Sport (which I just got a few days ago seems to have significantly more power than the 95. Both appear stock, no intakes, stock exhausts. Any idea what I should look for to explain the difference? I'd like to have the 95 running as strong as possible when I sell. | | | 07-18-2006, 01:08 AM | #34 | Senior Member Join Date: Jun 2003 Location: San Jose, CA, USA Posts: 253 | Quote: Originally Posted by SporTi I bought a 95 Ti 64000 miles 5 speed about a month ago.

My 91 318is seems to make a lot more power than when I bought it a year ago especially at the top end - I think the M42 is finally really getting broken in as it passses 130K. __________________ Andy Chittum - Mad Man Motorsports | | | 07-18-2006, 02:32 AM | #35 | Senior Member Join Date: Apr 2004 Location: Pennsylvania Posts: 218 | Quote: Originally Posted by bmwpwr I have had both a 95ti and a 96ti.

In 96 big brother mandated OBDII and a smog pump. These changes caused the M42 to lose a bit of power. To compensate BMW changed the stroke to add some torque to the motors to keep them up with the previous years models. The quicker reving 95 has a lot to do with not having to drive a smog pump which has parasitic power. As far as power differences there was something on a dealership level that cars taken in for service were hooked up to a computer and downloaded a milder program which robbed them of power. A shark upgrade should help out with this. Also there was a trick in spreading the cam timing out that helped out as well. | | | 09-02-2006, 05:40 AM | #37 | Senior Member Join Date: Jun 2003 Location: Halethorpe, MD Posts: 1,028 | OK, couple of problems here: I assume when you say smog pump that you must be talking about the Secondary Air Pump, which is not belt driven and therefore causes no parasitic loss. The last time I looked at my M44 the only belt driven items were the AC compressor, alternator, power steering pump, and water pump. The other thing you're talking about was a Technical Service Bulletin to deal with customer complaints of a rough idle. It involved a software "update" and a slight adjustment to the timing to smooth out the idle. The uncofirmed(AFAIK) internet rumors about this adjustment indicate that it causes a slight reduction in power, but I've never seen anybody back that up with any kind of before and after comparison. | | | 09-02-2006, 05:52 AM | #38 | Junior Member Join Date: Sep 2006 Location: House of the Mouse Posts: 20 | Sorry about the pump being driven by the motor. Meant to say the addition of the pump and OBDII caused a reduction in the power of the M42 like the M50 so BMW upped the torque to try and keep the same seat of the pants feel. As far as the software update that has been verified by a number of people arround this area, on previous ti boards and by a number of BMW techinicians that I associate with. | | | 09-03-2006, 12:39 AM | #39 | Senior Member Join Date: Jun 2003 Location: Halethorpe, MD Posts: 1,028 | What's the difference in HP and torque before and after the "update". I only ask because I've never seen any actual numbers. Does anybody know what model years it affected. Was it all of them? | | | 09-03-2006, 02:17 PM | #40 | Junior Member Join Date: Sep 2006 Location: House of the Mouse Posts: 20 | The update affected the M44 engine in the ti, z, and 318i/s autos from '96 to '98 I believe. Ten years ago somebody did do the test on the dyno and found it to lose about 5-7 rwhp and a couple twisties. Cannot find that discussion now because it was on a ti board I use to run which I let go a few years ago. One of the BMW techs that I have known for years was able to get the power back by splitting the cams 1-2 degrees. | | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
