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
Pre-silencer, 4ply flex pipe and bungs
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
