Remove unnecessary stuff out of the engine bay and relocate coolers.

Posted by martin on 12 September, 2007 17:24 | Permalink | Engine | Hits (1713)

You might have noticed that I've removed N249 and vacuum reservoir. And I relocated the N112 value which controls the EGR valve for the Secondary Air Injection system. It does make the engine bay much cleaner and it would be super easy to check and swap spark plugs.
updated: I removed N112 also. and note, you can replace both N249 and N112 with 30ohm/10w resistors.

And the vacuum reservior is working with N249, once you remove N249 you can actually remove the vacuum reservior. Want to remove N249? Check my post I made more than two years ago. Click here. The first paragraph is exactly telling you how to remove N249.

If you really don't know what N249 is,  then just read document below.

Get pure RPM signal from ME7.5 ECU system without taping the coil pack.

Let us make it short and easy, the key is right in the box, which is just beside the ECU. Open it you would see some connectors in it. Get the *one* of them and tape your wire with one of the pin of this connector then you can get pure square wave RPM signal from it.

Just get it installed today. In fact, I was waiting for the Special Edition of the 4nd generation of HKS EVC in black color for a half year. Suddenly the headquarter of HKS in Japan announced the 5th generation few months ago, and I decide just get the latest one instead. :)

Well, in fact, i wait for this one about two months, but anyway less than a half year. LOL

Aluminum sound deadener installation for a blue bug!

One of my friends made this aluminum sound deadener for VAG A4 Chassis, such as New Beetle, Golf, R32, A3, TT. And the other friend of mine wants to get it installed. So we just installed it today. Drill holes by ourselves. :) Just an easy DIY job.
