SAI Delete - what are the real pros and cons?

[K04-B6]

The SAI system can be effectively coded out via tuned ME7 software. It can be done for stock tunes, and any other stage of tuning. There are 2 methods of coding it out.

I apologize for bumping this comment back up but I'm curious to know how you do this? My SAI is removed with resistor in place and I never got a CEL, my N112 has always been hooked up even after removal of the system and I've never got a pass for readiness ever since. What is your method?

Thanks

to pass readiness you need to code out the checks for incorrect/insufficient flow, there are a few spots in the me7 some for the mil light and others for the actual readiness tests. There are people that can do it for you for a fee, but if you want to learn more about it I would suggest making an account on nefariousmotorsports.com and reading about it.

Thanks i'll make an account!, sorry again for the ignorance but what does me7 stand for?

its the ecu firmware of said ecu, in the b6 the version would me7.5, just a heads up the me7 system has one of the steepest tuning learning curves of all the ecu's I've ever worked with.

I'm not the best with software's so it'll take me some time to learn lol

Read the community Stg 1 thread for the B6 and you will start to understand. Then search for threads using keywords to fill in the gaps. Once you have a handle on the map names (which do make sense once you grasp the German words involved in the naming convention) and their uses (the Alfa Romero Funktionsrahmen that is translated to English is gold for that) it really isn't that hard. You aren't doing ASM patches, you are just changing map values.

Use TunerPro to start as WinOLS has its own learning curve and you won't be using most of the features to start with anyhow (bonus is that TP is free). Grab the utilities to correct checksums after your changes, Nefmoto flasher to flash your file, and a definition file for the s/w (.xdf file for TP to show the map locations - I use the 518AK 003 which works on the 03-05 ECUs and is well defined) and you are pretty much set. It is all learning by doing after that.

Use the method EuroxS4 mentioned in post 82 if you still have your N112 installed. It will basically change the SAI flow request to zero, so when the ECU sees zero flow it thinks all is right in the world. Readiness passed because the system is working as expected. I run it on my B6 and it shows as passed (although VCDS isn't always correct in that regard). No testing where I live now. I did use to have to pass testing when I had a Mk4 VW. That did pass using the above method FWIW.

Keep at it and you will get it. Just don't expect anyone on Nef to spoon feed you. They all started where you are at some point and know if you are reading and understanding or just want to be led. The whole point of that forum is to learn how to tune yourself, so they can be pretty brutal if you aren't pulling your weight in that regard. If you do your part, they are actually very helpful. When I had to code out my SAI on the Jetta years ago and couldn't find the MSLUB map in my file after honestly trying, someone gave me the location within minutes. Good guys that want to help you help yourself basically, even if that means tough love sometimes...

EDIT: I see you have a 2002 in your sig line. I think the file and definition you need is a 518F for your ECU - do not flash the Stg 1 file to your ECU or use the 518AK s/w. You have a different processor in yours so it will not work. All the basics are the same, so the rest of my post applies. You just need to use a file appropriate for your ECU. Good luck!

Wow very informative! I've been searching the threads on nefmoto and there's alot of things I don't understand yet but like you said, a little of reading and filling in the gaps and I'll eventually understand it.

Thank you for all of this info! Much appreciated
