IQ Limit EDC15VM 2.5TDI

by **Gregotovar** » Fri Jun 10, 2016 9:30 pm

Hi to All!!!
I have a problem with a friend's car.
I've read that there is a limit in pump for VP44 Bosch cars in VAG 2.5 TDI.
Only here i've seen that isn't correct and limits are in ECU.
I've only seen that there is a 3d limiter located in this ECU at 4D9CA.
I don't know what is Y Axis in this Map.It looks like a selector.
Where are these limits???

I've tried to find everything and in 8bit mode but with no success.

I have a 2.5 tdi Damos but for Transporter and there is the typical 15 39 51,to overpass 51 mg.

ECU is 0281010494-4B1907401D SGD04 AYM Engine 155HP.

Look for 50mg values

Hi remapmaster!!!I will try it but in diag done with 50 value after or before any special value like 1.9???
Factor should be (255/50) x100 to ser it un vcds and un this case it hace to be 255/50 but i can't find factor and values.
Thanks for The reply.
Any direction Or sector for manual codeblock???

yes i've seen 39 80,but i don't know if 2.5 vp44 doesn't go over 50,2.
In this case i can not see it and i've seen a factor for this.
Turbo Diag Factor:53A04 value 980 i supose for 2500mbar.
Fuel Limit Max is possible 53AAC???
Value is 508,and 255/5,08=50,19685 approx 50,2.

In this case is possible to pass 50mg??? or is no limit???
No for diagnostic.
When I finish the file I'll test with vcds.
