DIY- EGR Blocker Plate And Finger Stick
 

This modification bypasses important pollution control devices and should be used for race applications only. Use at your own risk.


Here is how I installed an EGR blocker plate and a finger stick. Doing this blocks the EGR passage to the intake thus preventing soot filled exhaust gasses being fed back into your engine.

The following photos show where you'll be installing the blocker plate.

1. I found it easiest to use a 12mm deep socket and a ratchet. The 2 bolts will be pretty tight so be prepared to put some effort into loosening them. Soaking them in a penetrating liquid is recommend.
2. Make sure that the EGR gasket goes between the exhaust pipe flange and the plate. Putting the gasket between the plate and EGR runner could allow the system to leak.

Installing the finger stick tricks the PCM into thinking that the EGR system is intact.

The finger stick itself is very simple to install. I recommend soldering all connections. Use a lower wattage soldering iron (under 100 watts) with quality rosin core solder for best results.

First thing you'll do is find the yellow wire going to the MAF sensor. Cut this wire in half near the large wire raceway on top of the intake. This is the only wire that you will cut. Next, using your wire strippers, open up a space in the Pink and Grey wires going to the MAF and also the Blue/White wire going to the lower terminal position of the EGR valve connector. (LBZ will be Brown/White).

The connection are as follows:

• Green/Yellow of fingerstick connects to PCM side of cut Yellow wire.
• Blue of fingerstick connects to Blue/White of EGR connector. (Brown/White for LBZ)
• Yellow of fingerstick connects to MAF sensor side of cut Yellow wire.
• Grey of fingerstick connects to Grey of MAF sensor wiring.
• Red of fingerstick connects to Pink of MAF sensor wiring.

Make all connections close to the wiring raceway. Tape or heat shrink connections and hide fingerstick inside of raceway like shown below. Remember the PCM uses voltage and resistance feedback to monitor this with tight parameters. GOOD CONNECTIONS HERE ARE A MUST.

This should be completely invisible to anyone looking under the hood or using a scan tool.

Looks good.

thank goodness i dont have an egr :)

nice write up

Awesome Writeup Johnny! Thanks a bunch.. I need to get this done to my LBZ as well...

Just get the EGR delete kit from PPE and EFI Live and be done with it. :pca1:
