Yes, 13, had originally joined for info on replacing a CPS 2 years later i'm here.

I'm enjoying my e46 just like everyone else, learning, maintaining, cleanly modding, and soon will be manufacturing parts. (quite excited about that, just tested my homemade vacuum forming machine and will be making parts out of petg and carbon fiber) click the sig link for more info.

Come on now!!!!! PEEK. I expect more from you.

Edit: I've read about this so-called strange area of the RPM band on 330's. However, on my 2001, I do not have any such lag or jerk or whatever it is anywhere across the RPM band. Just a F'n annoying wa wa wa wa wa noise that I can't diagnose!

I've been following some of these threads despite not experiencing the issue myself.

I'm just wondering - do you still get the same behavior if DSC is disabled?

Since you're a nice guy, I'll answer.

I've answered/discussed this numerous times, yes. it has absolutely nothing to do with DSC and is nowhere near DSC threshold. Talking normal take-offs getting groceries, going to DMAX's comedy gigs, etc. Normal driving.

I'm not worried or complaining or giving it too much thought. It's not a big deal, just slightly annoying to deal with.

This is interesting info, thanks for posting. Just so I'm clear... you weren't able to remove the "switch", so you're not sure if taking it out will change the kickdown? Cityjohn, if you buy the pedal, I'd be real curious to hear what happens if you remove that "switch".

Huh? No. I did remove the switch. I drive a manual. No kickdown for me. That's why I removed the switch cause I don't need it.

My 2002 manual pedal is for sale. i'll throw in the switch if someone needs it. if not, i'll chuck it in the ocean or feed it to a squirrel.

switch is just a clicker. does nothing but makes noise

Crazy thought...which I'm making up for you...see if you can turn it into a non-crazy thought...and don't yell at me!

02 sensors when bad seem to trigger a signal with a straight climb up, as opposed to a slanted signal increase...I think that's right...maybe the opposite.

I'd guess 02 sensors might trigger a jump, a kick forward from more gas being called for all of a sudden...

Something like that. I'm sure you have newish 02 sensors, but maybe other sensors are giving a dicey signal that's triggering ecu to give it a kick of gas. When AC comes on...I know the idle increases...all this happening without AC?

If that doesn't work, just replace your cooling system to relax you and channel your car's ailments. Have you been doing your readings of Bentley everyday?

ac doesn't play a role. i'm going to unplug my maf and try again (i thought i did this before but not 100% sure)

like i said i have a new throttle body coming. im also thinking about the golf-t mod... anyone know if the flap in the exhaust is in any way wired to the DME? I highly doubt the flap opening or closing would require timing or fuel changes.

whatever change is happening, it's happening at around 2,500 rpms upon increasing throttle input (will not happen if throttle is steady)

Have you considered some problem/stickiness in the actuation of the VANOS? I would also inspect engine/trans mounts, guibo, etc.

I do not think fuel metering (ie. bad O2 as dmax suggested) would create a jerk--more likely a change in timing.

I don't want this thread to turn into a troubleshooting thread. This has been hashed out/discussed numerous times already. The end result is always the same.

No matter what you say or can think of, it's been done. Sometimes twice. The entire car is pretty much brand new front to back. you guys know me!

This is something I'm privately troubleshooting and investigating. I highly highly HIGHLY doubt anyone can come up with a workable solution. This is just something I have to handle on my own (which I am)

I appreciate the help though. I can manage.

I'll handle it on my own unless I need specific specific help--detailed knowledge on something extremely specific.

Also there's a handful of people out there experiencing the same thing on their manual 330s. So obviously if I find a solution, I'll let the community know.

I also have a sudden "kick" in acceleration around 3100-3300 RPM. I didn't notice this until I got in on the AA group buy last year. It's almost like the car is coming onto the cam or the secondaries kick in on a carb'd engine. I'm not really complaining about it, just curious.

I asked AA about this issue but never got a response.

Was this as a result of AA? (tune i'm assuming) or did it do it before?

This may not be the same problem as i am talking about.

No problem. Part of the reason I made this thread is because over the years I feel there was a misconception that there's an actual switch that electronically activates kickdown. people go NOOO DONT USE A MANUAL PEDAL OR ELSE U WONT DOWNSHIFTING!

Wrong! it's just a clicker. we all know that the kickdown "switch" isn't a switch at all. but just a clicker. like something you train dogs with.

Mango, does the throttle response feel different otherwise? Every auto BMW I've driven revs much more freely in neutral than the manual equivalents. I don't really understand why since the DME software is the same. I thought maybe the potentiometers in the pedal might be mapped differently

you bring up a valid point. it feels exact the same as before.. i think these "potentiometers" (I put that in quotes cause I honestly don't know how they work or are set up) are detachable by two torx screws. ill try to check it out. maybe they can be swapped?

now you've got me worried... car seems fine though!
