Title: 018DC -> 018DH idle problem Post by: 1k.remap on September 05, 2021, 03:40:17 AM 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 :) Title: Re: 018DC -> 018DH idle problem Post by: Blazius on September 05, 2021, 07:43:02 AM 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.

This means that the conversion factor for KRKTE of 018DH will be different - 0.0001666 instead of 0.000111 of 018DC Title: Re: 018DC -> 018DH idle problem Post by: Sandstorm3k on September 05, 2021, 09:46:40 AM Why not just crossflash this ECU?

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.

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.
