This is a rough rule of thumb. That means that you should really determine the proper plug by reading the color of the plug at a minimum.

In any case, he is sending me a special chip to deal with this. After that, we may consider colder plugs. He also considers the difference between "ping" and "knock" to be a question of degree, but thought it a bit odd that I can hear more than a few seconds of continuous "ping" at times.... In any case, I can't fault the service....Josh is going working to resolve my problem. Roger W. Graves RogRacer@aol.com '95 M3, JC Euro Intake, with a special "high compression" early build S50....

Date: Sat, 4 Nov 2000 14:03:45 -0500 From: "NickG" <nikog@MediaOne.net> Subject: Re: [E36M3] JC Euro Intake and Pinging Before I installed a turbo, I ran a JimC chip. If I were to floor the throttle at 4000rpm, it would ping/sizzle till about 4600rpm. Then the noise would go away. If I were to floor the throttle at 3000rpm and rev it out, it would NOT ping at all in the 4000-4600rpm range. I had the chip reburned a few times to reduce the timing and add fuel in the problematic 4000-4600rpm range. In the end, the ping/sizzle was gone. But, my butt dyno said that the car was now slower. It seemed much more responsive with the extra spark timing (and matching sizzle :) I think that when going wide open throttle at 4000rpm, the engine encounters a greater load. Hence, it is more susceptible to pinging. But starting at a lower RPM removes the extra burden in the RPM range with the highest cylinder pressure (between 4000-4500rpm where the torque peak occurs). My opinion is that, as was previously stated, the noise is when the engine is just on the virge of heavy detonation. That it really doesn't cause any damage. Now that I've added a turbo, I can make it 'sizzle' with a mere .75 degrees more timing (again, in the 4000rpm range). While the pinging doesn't sound too good, the car is definately more powerful with the added timing. But considering I'm running a lot more cylinder pressure, I'd rather remove some spark timing (and lose some power) to insure that I'm not running on the ragged edge.

If the knocking\pinging is related to the type of fuel, would a high performance gas additive take care of the detonation? If so, what brands have been proven effective? AJ 95

Nick, maybe > you can help these folks.. I think that it's much harder to stop pinging/detonation once it is in full force, than at the very beginning. It also depends what kind of load the engine is seeing, like what gear it's in. If the car is in 2nd gear and starts pinging in the midrange, there's not much time for the DME to retard the timing and stop the ping before you've reached redline. But when in 4th gear, there's a lot more time for the DME to intervene and pull out enough timing. Nick

#9. Strange problem - fan wouldn't stop. - from GRCouture@aol.com
Top
Date: Sat, 4 Nov 2000 16:37:03 EST From: GRCouture@aol.com Subject: Strange problem - fan wouldn't stop. Hey guys, Strange thing happened today after I moved my car into the street so I could rake some leaves (gotta love fall in New England). After about 2 hours of raking, I noticed that the front fan behind the kidney grilles was still spinning. I turned the car on to make sure that the battery wasn't dead, and thankfully it started up fine. But after shutting the car off, it was still spinning! Well, after about 20 more minutes searching for a fuse to pull, I figured i'd try turning the car on again. This time, I activated my air conditioner, and then turned the car off. Well, this seemed to temporarilly cure the problem - as the fan isn't spinning anymore. Anybody have any ideas to why it was spinning for so long? It just seems like it never got the signal to turn off after shutting the car off. Unfortunately, my BMW dealership doesn't provide service on Saturdays - so I'll have to wait until Monday to ask them about it. Seems like a small problem, but it could be linked to a potential bigger one. Strange. Thanks in advance for any and all advice/feedback.

#10. Knocking - from Monty Baugh

Date: Sat, 4 Nov 2000 15:43:06 -0600 From: Monty Baugh <mbaugh@telecom-management.com> Subject: Knocking My car ('96) will knock all day if I get cheap at the gas pump and put in lower octane fuel. Won't knock at all, however, running 93 octane (Sam's Club Gas, 1.42/gal. this week). Makes no difference if the knock sensors are present and working properly, if you run cheap gas in an engine with 10.5:1 compression, it will knock when loaded, under full throttle, or when accelerating.
