Default Evry mod : Holy Cow!

Just completed the Evry mod on my 02 Jetta 5-spd. Used a small 1k ohm 15-turn potentiometer from Radio Shack. Super easy to do. Measured the resistance at the point where the engine began to shudder slightly... turns out on my car 470 is the sweet spot. Anything more and the idle is terrible. Moreso than I'd be comfortable driving with. At any rate... I'm IMPRESSED! I lined up against my buddies 03 Jetta Wagon (he just bought it). The other day we were dead even against each other from any speed. With the Evry mod I flat out walked away from him - in a cloud of black smoke! LOL! Tomorrow night we're gonna wire up a switch or some other method of avoiding the CEL..... and he's gonna do the mod to his Jetta as well. Thanks to this forum for the wonderful info!!!

one thing i'd recomend from personal experiance is a boost gauge, and a boost control device. as you're adding more fuel the boost will go up, and spikes will increase.

how do I know? I'm putting in a new head gasket this summer from boost spikes caused by evrymod over fueling.

Turbo gauges can be purhcased for REALLY cheap. there are really nice kits avaliable for the A4's with everything needed for less then 100 dollars.

It tricks the computer into dumping more fuel into the engine.

Thanks for the advice. I will probably order a "Dawes Device" very soon. I am going to wire up a switch for this Evry mod... I'll only play with it every once in awhile. Although... never hurts to have your bases covered.

Hi.
Im from Sweden and im new here in this forum.
I just want to give you a friendly advice, back off and dont go so high!
The 90 hp TDI, can take it better than the 110 hp engine.
Im a manufacturer of lots of different tuning boxes and CPU:s and i have learned it the hard way...

Hi Jorgen!

Don't go so high? I'm not sure I understand what you mean. This is the 90hp TDI engine. Maybe that advice wasn't even directed towards me.


In other news, I wired up a micro-switch... mounted it under the dash... and while it's off there is indeed no Check Engine Light. Flip it on while driving and there's a sudden blast of power. Couldn't be happier! My boost valve will be here next week. So til then, not much playing.

I love my TDI!

We are selling a low cost tuning box that works in a similar way. It is the same adjustment procedure, pull it up on idle until it stutters and then pull back a bit. My experience is that if you drive with an adjustment too close to the "stutter" and "shut off" limit and often drive like you stole it, your pump will eventually bite the dust.
I hope i did properly understand what kind of mod you have done. My english is a bit rusty.

I just wanted to share my experiences...

I've been interested in making an Evry Mod, but the thought of getting the right parts and putting them together is a little intimidating. A detailed write-up would be nice.

I don't think it would be hard, just need to know where to hook the pot to and how to dial it in. Someone help please

It helps to have a multimeter. This is what I got from radioshack:

Multimeter:

1k Ohms Potentiometer:
http://www.radioshack.com/product/in...entPage=search

On/Off Switch:
http://www.radioshack.com/product/in...entPage=search

And then some thin wire. I had some laying around. I'm not sure how important exact gauge is.

Here is a horrible diagram i drew in paint, hopefully this will give you an idea of how to wire it with a switch. The switch I used has a light in it, so i had to connect it to a 12V source.

Why do you have it going to a 12v source?? for a light? a 12v source is not needed with a simple switch setup.
