Title: Car not doing what im asking of it :( Post by: carsey on February 28, 2015, 10:48:19 AM Got chance to get a log today of my car (1.8T with k04-064) and flashed one of my maps on I made up which I thought should have it at a mid level of power.
The load isnt following specified which I have flatlined at 180 in LDRXN. Engine load requested and corrected are well below what ive set it at. Log is attached. I can see its pulling 8.25CF which is a LOT i know, but ive put this down to the standard timing tables for a k04-023. Any pointers? Just want to get it running safely before I take it for proper mapping in april. Looks like my axis might be set a touch too high in KFLDIMX? Thanks Chris Title: Re: Car not doing what im asking of it :( Post by: carsey on February 28, 2015, 11:44:17 AM Newer log with axis changed. Looks a bit better.

Restore the maps from your original SW and tune them by hand. Title: Re: Car not doing what im asking of it :( Post by: carsey on March 01, 2015, 12:07:28 PM New log. All is well and nice again...Just a bit of correction on engine load top end I need to look into

Feels pretty epic on the road...just need to sort that midrange boost out and chuck some timing at it. Title: Re: Car not doing what im asking of it :( Post by: aef on March 05, 2015, 03:43:00 AM edit: i had a old version of ecuxplot which didnt show the log correct
no throttle cut here! What was your intention behind your KFLDRD? Which injectors are you running? log should look like the attached one (same setup with ldrx 180 too) Title: Re: Car not doing what im asking of it :( Post by: adam- on March 05, 2015, 04:19:05 AM He's running 630cc Bosch's, Marcus. Same as us! :)
Title: Re: Car not doing what im asking of it :( Post by: aef on March 05, 2015, 04:40:47 AM Okay... TVUB is wrong then. Thatswhy FKKVS has such big numbers in it.

What was your intention behind your KFLDRD? Which injectors are you running? log should look like the attached one (same setup with ldrx 180 too) Already mentioned to you but a linear KFLDRL will let the boost I set in KFLDIMX follow exactly that map, instead of DRL stepping inbetween the WG duty before linearisation and after it. See picture below. The FKKVS values are off my k03s tune where I logged over 30minutes/20miles or so to get a good scope of data to work off. Needs doing with this 064 turbo, but will let the tuner sort that out when its in for mapping first weeks of April. |
