Title: Seasoned Mechanic - Total Newbie to Tuning - OHIO Post by: flashburn on August 05, 2013, 08:05:44 AM Hi All,
I'm a big DIY'er and I built my own GT28R turbo kit for my 2004 B5.5 VW Passat 4 Motion 5 Speed. I've built a few toys including a drag bike, RX7 turbo and an airplane (still under construction). I can't bring myself to pay someone else to tune my car, so here I am to learn. My tuning knowledge expands into knowing about AFR/EGT/Timing retard and what I WANT those figures to ideally look like - but I have never dabbled in the actual tuning portion. So I guess I know what I want, just not how to get there. I'm looking to run my car around 300 CHP or about 19-21 PSI on the present setup. I'm not trying to max out the turbo or really really push my stock bottom end. Looking forward to lots of reading and learning. My setup is as follows: GT28R FMIC 550cc EV14 injectors 3" MAF housing Title: Re: Seasoned Mechanic - Total Newbie to Tuning - OHIO Post by: flashburn on August 05, 2013, 12:53:45 PM So as I'm reading all day today - I think I've discovered there is not an ECU definition file for my ecu: 4B0 906 018 DP
This essentially means I'm SOL - no? Title: Re: Seasoned Mechanic - Total Newbie to Tuning - OHIO Post by: ddillenger on August 05, 2013, 01:09:07 PM No, it just means you have to either:
A: Define it yourself B: Find someone you can pay to define it for you. If you choose A, I'll help with any map locations you can't find on your own. If you choose B, I can steer you towards those that won't do you wrong. I personally hope you choose A, but defining a file from scratch is one of the more tedious things you'll do. Welcome, and good luck. Title: Re: Seasoned Mechanic - Total Newbie to Tuning - OHIO Post by: flashburn on August 05, 2013, 01:49:13 PM Can you point me to a good FAQ/read about mapping locations? I haven't stumbled on that yet during all my reading today.

I haven't stumbled on that yet during all my reading today. The tunerpro site has a lot of good whitepapers and stuff on this topic. Title: Re: Seasoned Mechanic - Total Newbie to Tuning - OHIO Post by: ddillenger on August 05, 2013, 02:06:24 PM There is no DIY persay, you just have to whip out a hex editor, 2 similar files (one yours that you need to define, and the other with known map locations) and look for patterns. It gets easier if you use winOLS, but the learning curve on that is ridiculous.
Otherwise, switch to a different file that has definitions readily available. The S4 guys all use either the M box for manual trans, or the L box for tips (8D0907551M or 551L). The file attached is 018DQ, also for a 2003 passat. Not sure if it can be softcoded for a manual trans, but it may be worth flashing and trying to find out. I defined it a while back for a buddy. Has a lot of important things in it, but it's far from complete.
