2.5 TDi max IQ limitation

Postby Ashleymark » Fri Mar 03, 2017 12:00 pm

Hi, I was hoping one of the many knowledgeable people out there could give me a shove in the right direction.

I am trying to raise IQ limits on a 2.5 TDI Audi a4 155 HP aym engine.

I know many people say limit is in pump not ECU but from what I have read the pump limit is higher than the 50.2 mg/str that ECU is limiting to.

I have raised 2 torque maps to bring IQ past 50.2mg/str, and have raised 11 single values of 50 which I believe to be single value limiters. But it has never exceeded 50.2 mg/str. I know it can be done and I must be missing something but for the life of me can't find it.

I know on the Ake engines there are three torque limiting maps and numerous single value limiters. I have found two of the maps and I think all of the single values on my dump but cannot find the third map anywhere (is it there)

Address for what ive found

4e6a2. Torque1
4d9ca. Torque2
52c46. IQ limit 1
52c48. IQ limit 2
52c4c IQ limit 3
52c56. IQ limit 4
52df4. IQ limit 5
52fa2. IQ limit 6
53158. IQ limit 7
540a2. IQ limit 8
54fc6 IQ limit 9
5522a. IQ limit 10
55234. IQ limit 11.


Obviously I have found many other maps. But these are the ones that relate to my issue.

Thanks for reading

Hi, thanks for reply.
I think I should of been a bit more specific/informative. Of the maps that I've found, all the single value limiters are obviously single value maps. Of the two torque maps I have found one is 25x3 and one is 8x3. But after several hours of screen staring I still cannot find the 21x3 map I've searched in every way I know, but I'm still a begginer at this. It's taken a lot of time, reading and brain power to find what I've found, and I'm sure I'm close now. Any advice or ideas of finding it. The only image I can find of 21x3 map is for a Ake engine and Im sure I don't have any maps the same. Again any help is greatly appreciated.
