I bought a spare 1981 VW T3 in 2010 that was supposed to be for parts to improve my other T3, but the body was in such better shape that I decided to invest in this one and sell the other.
Long story short in this picture, April 2010 completely stock and Februari 2011 just after new license approval with 115hp 2.0 8v gti engine, 4x diskbrakes, LPG system and poptop. That was one buisy year for me..

I have made improvements every now and then to have it suit my wishes, and now it was time to get a new engine. I bought a 1997 AEB 1.8T 20v with gearbox, which I want to use in the van. Since the engine is in the absolute rear, the gearbox had to be flipped around to have any use.
Engine when I picked it up:

Cutting an adaptor plate to fit the engine and gearbox:

Here is the engine coupled to the gearbox by use of my self cut 15mm adaptor plate:

I bought several parts for the exhaust to make a full stainless 3" turboback system with 2 silencers for a little less noise since I have a little daughter that sits right in front of the engine   I am currently on a 2.25" catless steel system with just 1 silencer, which is not that loud inside the van, but a bit anti social to drive through urban areas when people are sleeping.
I heared the turbo takes away some of the engine noise as well, so I am mainly looking for performance in this 3" system.
Here are the parts, still need to buy the pipes and bends
Rear silencer

Pre-silencer, 4ply flex pipe and bungs

Turbo flange

Working on a power steer delete at the moment, got the bracked hacked up and just need to find a proper pulley for the water pump and a belt.



So about the digital stuff, I found very little useful information about my type of ecu (8D0907557 0261203551 355966).
Even with maps that should be alike, I cannot make links between maps since the axis data will not make sense.
As for the map packs that should be suitable for this old type of ECU (tried 8D0907551G.kp, 8D0907558M.kp, 8D0907557P.ols that I found on this forum) , I still get no usefull descriptions or axis data.

I found the following map elaborations when I searched on the map names via google, however they are not all in my ecu:
0996E 16x16 (inj. time) >found this one, I presume the Y axis is RPM (15-170 with 40 offset displays as 600-6800rpm) but the X and Z axis do not make any sense if I look at it as beeing injection times so it should be something else (g/s or load on X? Don't have a clue tbh...)
09B88 16x16 - Ignition angle (map for normal conditions) > found this one
09CAC 16x16 (ignition angle at part throttle 23) > found this one
0A0C6 16x16 (ignition angle at part throttle 33) > found this one
0A1DA 8x8 - Ignition angle correction due to TCO or TIA > found this one
Then there are a few that are not in my potential map list:
0A22C 16x1 (ignition angle at WOT)
0AA67 8x1 (overboost)
0ACFB 9x16 - Target Load
0ADEB 9x19 - N75 precontrol
0AE7B 8x12 - N75 DC correction due to TIA (coeff)
0AF6B 4x16 - Load limitation due to altitude
0996E 16x16 - Injection correction to achive target Lambda (coeff)
0A22C 16x1 - Ignition angle correction at Full load (additive)
0A73B 8x12 - predicted Load due to TPS

I dont know how reliable the descriptions are since I just picked them off the internet.
My first goal would be to rewrite the standard AEB file to an AJL file since those engines and managements should be identical, this way I can maybe learn what changes Audi has made to the file to receive 180hp instead of 150. If I manage this, then I should feel confident enough to make adjustments according to my own needs. However, before I can do such I need to identify the maps and understand the data...
I know some advise to just buy another ecu, but that is money that I cant spend on other parts. I'd rather work with what I have unless there is absolutely no other way.
Hope you guys can think with me! I'll keep posting my latest mods to the engine and progress in the project  

Ahw, I must be misinformed there then. I thought I saw an AJL with throttle cable? Searched it again but I seem to find the A6 C5 AJL 180hp with m3.82 ecu?
To your edit: thanks for the additional info, I have searched the hexdump for maps but came to 36 maps too so I assumed that winols had done a good job. As you may notice I do not yet master the ECU lingo   but at least you understood what I ment.

My exhaust will go from the turbo straight through over the axle, then with flex part into a 180 degree bend, into the pre silencer, straight through to the back under the axle into a 90 degree bend into the rear silencer. From there it is basically optical, I will figure out how far apart the exit pieces will be by the looks of the rear (they come out both ways of the silencer in 2,5"). If it gets too crammed, I can route the exhaust over the gearbox to the other side, but I need to test fit the whole when I have the engine mounts ready anyway. I hope to find a workshop that will bend me the pieces in between the parts, but I think it will come down to welding it together...But thats fun too  

Okay, then I need to look again how to properly set up a file in WinOls  I'll try later on, maybe this will give me at least some more reference. All bends I want to use will be constant radius, I have learned that these will not have negative effects on gasflow.  I will think very carefully how I make this fit so I will never have to make big adjustments again. Hence the stainless 

Just received my Willem, now I just need to have a serial cable to usb. Should be able to get this thing working this week   the ebay chip is already inserted in the upper plcc32 slot, that will be my first read

Took me a while to get things working with the programmer, but I finally managed to pull the bin.
Any feedback on this? Should be written for a completely stock engine, untested.
I will use it to identify changed maps first, but the idea was to run this file untill I get more insight in how to adjust to my personal needs.
I have found adjustments in all my above mentioned maps, just slight increases in the bottom right at most occasions. There are also showing maps that I did not find yet, but I can tell from the hexdump that differs at some points. At least it is helpfull, and I dont see any wild increases in numbers yet exept in the load table.
Did I mention I ported my wastegate?  

hehe that was fun
Added screenshot of target load comparison
So far I have found about 14 changed map area's (where one area seems to consist out of 3 repeating patterns but I cant get them to show as a readable map in 3d mode individually), I presume the last part of the hexdump is different because of the checksum correction? There is a major section that differs from the original file. I have compared the two by using winols linking the maps together.

No, i'm not sure. This is one I pulled from a website, untill I get my ecu desoldered I cant be 100% sure about the file. In any case it seems to be a somewhat rare file/ecu platform since there is hardly any info to find on m3.2
Havent looked into it for some time, I spent most of my time on other subjects.
Finished my rear brakes just a week ago, and built in my spare rebuilt 2.0 8v because my exhaust studs broke off. Just to keep the van on the road for my holiday, I hope to swap the turbo in mid August.
Thanks for taking the time to look into the file, have you compared the tuned one as well?
New seals, gaskets, bearings and a pretty little cam with 11.2mm lift



Old block out and stripped


New one back in

and the new rear brake, 286x22mm vented/drilled with a 2011 VW T5 caliper


Have added another original file, a bin that comes from this site. Will use this one for reference now.

cool stuff here

Just desoldered my original chip, here is the file:
