Insert the device in the lower right corner, and move up towards the middle of the unit to start prying. Remove the underpanel.Ĥ) Remove the four screws and the brackets securing the lower glove compartment to the glove box rail.ĥ) Remove the pin holding the inner glove box to the glove box damper.ħ) Remove the cupholders as shown in this post.Ĩ) Unscrew the six TORX screws holding in the upper glove compartment and remove the upper glove compartmentĩ) Remove the Climate Control Unit using a plastic knife or some other prying device wrapped in cloth (I prefer to use a Craftsman rivet puller wrapped in a rag). Make sure all the parts shown below are there.ģ) Remove the two TORX screws (not sure of the size, sorry) that hold the underpanel below the glove compartment. E90/1 shouldn't be much different.ġ) Download and read the BMW iPod installation instructions found here.Ģ) Open your iPod retrofit kit. Running Comp's MOST aggressive lobes calls for either more spring or lowering the max RPMs.OK, here's a DIY for the installation of a BMW MOST iPod adapter for (in my case) an E92. Of course, one can always pump up the valve lift by making changes in the rocker arm ratio. So although long(ish) durations use to always accompany high valve lift cams, the most recent cam offerings have taken a big bite out of that requirement. Of course, the entire valve train has to be up to snuff to be able to repeatedly handle those lobes and, according to Comp, stock valve train parts won't cut it. It's a fine balancing act, to be able to achieve that without going too far but the Big Boys have nailed it.Ĭomp's been doing it for a while with their XE and XFI lobes and Lunati is now offering lobes of a very similar design. The trick is to open the valve as quickly as possible, accelerate it quickly but not so fast as to cause the lifter to fly off the lobe at max lift - only to come crashing down on the closing side of the lobe. They increased, what we usually refer to as the aggressiveness of the cam's lobes. One of the major benefits of recent (within the past several years) testing done by the major cam companies is they have been able to create camshaft lobes which result in higher valve lift while, at the same time, keeping the duration on the short(er) side.
