    need to adjust the ve table and check to see if it stays closed loop at idle after you adjust it. the int is trying to lean it out if your blm is close to 128 it will change a lot. if you post a bin I will change it .

    post the bin file you are running I will look at it.with out seeing your bin it is hard to say what to change,I would set afr vrs temp to 14.5 above 60 centigrade.

    rytari I been thinking about how you was doing on your project, I see you are from finland and was wondering how the climate was there compaired to about the middle of texas Huntsville area. I was wondering also if maybe you got a ticket from speeding? if you post a data log with the file you are running I will help you if I can. what I change with tuner pro I can post a saved log of what was changed with tuner cat I cant post what was changed just the bin file I use both tp, tc. ether way it is easyer for me than typing what to change and how much.my worn out v6 does 18-21 mpg and will compete with a lot of unturned v8s in normal driving that is at 65-70 mph and dirt roads and town driving. the way I drive. I plan on up grading my cam and a rebuild,like I said never tuned for a cam so this is very interesting to me.
