Hello guys
i have some kind of problem with my Passat B5.5 2002 EuroSpec
The engine is AWT, original ecu with partnumber end 018DC
I've got a spare ecu for mods from the passat b 5.5 with the ending of 018DH

Basically everything works ok, but i have idle problems. On original ecu (dc), i have steady idle, no grownups or downs, idle is great. Consumption on FIS ~1.0 l/h
On the other hand, when i put my 018dh ecu, i have bad idle, 1.6-1.9 l/h consumption. I checked KRKTE on ori and mod, and on ori krkte = 0.10478, on 018dh krkte = 0.069819

Can someone help me noob with this problem
Thanks in advance Smiley

Mate read the first section of the s4wiki. You need to port the fueling maps from original ecu , if you got the original fueling system.

You're wrong
In original firmware KRKTE is the same in 018DC and 018DH = 0.10478
CPU clock frequency in 018DH is higher than clock in 018DC.
This means that the conversion factor for KRKTE of 018DH will be different - 0.0001666 instead of 0.000111 of 018DC

Why not just crossflash this ECU?

Why not just log some data like it’s been said one million+ times already?   People are only good as the information they receive. And the information you’re giving is_____.  <. You can family feud fill in the blank here.  Take logs of both good and bad.

018DH is a 6.02 bootrom ecu, where as 018DC is a 5.12.

I still dont get why the need for the second ecu, sure beginner, but you cant really mess these ecus up if flashing through port , and even then a galletto /mpps all you need to recover.
