He had his injectors cleaned and blueprinted, and the were tested to be 168cc/min. If my math is correct, the factory spec is: 17.5 lbs/hr x 10.5=184cc/min. When they run the car on the dyno, it has an A/F ratio of around 14, so it's running lean. It has the 3.2 US headers, and a high flow cat, and a high flow exhaust, Conforti CAI, and a Conforti Chip. Otherwise, it's a stock motor. He has replaced the fuel pressure regulator, and fuel pump, with no change at all. He added a split sec piggyback controller for the MAF sensor, and while that made a slight difference, it's still running lean. He called AA, and they said they can burn him a chip, but he would need either larger injectors, or and adjustable fuel pressure regulator to increase pressure to solve the fuel issue. Problem is, he runs SCCA STU AutoX, and he must use factory injectors and FPR. Has anyone else seen this issue? I'm surprised there is a fuel delivery issue on such a stock motor. I'm curious why the injectors don't seem to put out the rated spec. Or is that normal? thanks, Chris 97 M3/4 ************************************************* Please help support the E36M3 list by visiting our sponsors: Bimmerworld http://www.bimmerworld.com Turner Motorsport http://www.turnermotorsport.com Eurosport High Performance http://www.eurosporthighperformance.com Rogue Engineering http://www.rogueengineering.com Treehouse Racing http://www.treehouseracing.com Elephant Motorsports Inc. http://www.elephantmotorsports.com DIGEST INFORMATION: http://www.bmw-m.net/resources/digest_info.htm ************************************************* -- No virus found in this incoming message.

I took it to AA in Miami. They installed stock US 3.2 injectors (21.5#/hr?) and dynoed the car about 30 times as they tuned one of their chips. Then they fine-tuned the chip during a road test. The car has run really sweet ever since. I can't explain the original problem, but I highly recommend AA for this type of problem.

I even replaced the VANOS hoping it would quiet down the engine a bit and help eliminate this problem, but it doesn't seem like that helped much (it did quiet down, just a little). My 8/95 build '95 has pinging problems with a Conforti Euro HFM & intake kit. I am using the "anti-knock" version of the software, and it still pings. I think Bora Akyol on the UUC list (or maybe it was Marco) did an informal poll a few years back about pinging problems, in which he found that the 95s almost always ping, with our without intakes, and even sometimes with stock software, and the OBDII cars ping occasionally, I *think* only with software and intake combinations. On my car it definitely occurs more often in warmer weather (as it seemingly almost disappeared over the winter), and it goes away when I use race gas (and then the car runs like a scalded ape, feels great). Is there any off-the-shelf solution to this problem? I ONLY use premium gas (Chevron 91 octane here in CA), so hopefully there is little carbon buildup in the engine contributing to the problem. I will probably run a bottle of techron in the tank soon to help clean anything up that could be there, but does anyone have any suggestions besides a custom chip?

Date: Sat, 15 Jul 2006 07:35:07 -0400 From: "Richard Sperry" <richardsperry@comcast.net> Subject: flow rate. --------------------------- Flow rate of the factory injectors I have a friend with a 1995 M3. He had his injectors cleaned and blueprinted, and the were tested to be 168cc/min. If my math is correct, the factory spec is: 17.5 lbs/hr x 10.5=184cc/min. -------------------------------- If I'm not mistaken, 17.5 #/hr*(1hr/60min)*(1gal/ 6.5# avg)*(3785cc/gal) = cc/min 169.8 cc/min. Just about right on the money.

#6. Underpanel Copy - from jmihal@jt-designs.com

Date: Sat, 15 Jul 2006 08:32:18 -0700 (PDT) From: <jmihal@jt-designs.com> Subject: Underpanel Copy Thanks to the watchful eye of my friends here on Suzy's list, an immitation of our under panel assembly for your beloved E36's has been exposed once again. Every few months I am reminded that people will attempt to capitalize on our hard work. In a market as niche as for your E36 M3's, patenting is not an option due to cost vs return. To date, we have yet to profit as much as would have cost to patent our under panel design. But this did not deter us from developing a product that the E36 needs, we know that you are educated and this is why we continue to provide the E36 M3 crowd good ideas. If Rip Offs like those in Mission Viejo (via Canada) become successful, it will certainly mean an end to any interest in JT Designs developing new product in the future. (I know we have been quiet for a while but that doesn't mean we are not up to something ;-/ ). We here at JT Designs rely on you to weed out what is not right and to support those who suport you.

Date: Sat, 15 Jul 2006 12:26:55 -0400 From: "dhogg" <dhogg@suscom.net> Subject: RE: Flow rate of the factory injectors & Techron Chris, Stickley has told me that he sometimes sees lean conditions in stock motors with clean injectors at high RPM. No good reason why. The Conforti chip exacerbates this condition, from what he has said. Apparently the Shark program leaves no room for mixture or fuel quality variation at high RPM. (Disclaimer: I'm not sure Chuck and the Shark are the best of buddies.) Having said that, I've got a Conforti chip & intake on my '98 M3/4 with 103K miles. It was really getting bog slow until I ran 2 consecutive Techron treated tanks through it last month. That stuff really works! It's much happier now, though it still prefers Sunoco 94 (Sorry, California dudes!) on hot summer days or I hear detonation under load. Dave Hogg In smog-enriched Central PA Is Ozone a nutrient?

I also just bought a perfect / brand-new / never-used 7.5 Contour that was used as a spare for $160 including shipping. I considered this a very good deal compared to other single wheels that have been posted for sale so you might be able to get a good price for the 7.5" if you sell it separately. The autocross or track crowd may be a better group to sell the four 8.5" wheels to as they like having 8.5 inchers on all four corners and don't care so much if the finish is marred a bit. And they would probably not be very interested in the 7.5" spare which would enable you to sell it separately.
