Ive been trying to get my low trims adjusted for cruising around but my car is just a big bitch and does everything possible to throw curve balls.
I have my SAFC2 points set like this
1k
2k
3k
3.2k
3.4k
3.6k
3.8k
4k
5k
6k
7k
(PROBLEM1)
Now I sit in the parking lot car all warmed up and hold the idle at 1k RPMs. The low fuel trim (lft) goes to 112% so I adjust to something like +8% on the SAFC2 and it comes down around 100%. Now I move up to 2k and the lft jumps to 135% and no amound of adjusting brings in down...
(PROBLEM2)
Sometime the fuel trim will get locked into place. While adjusting it will just freeze on a number and not adjust anymore. Right now it's stuck on 110.4% no matter what rpm or what adjusting I do with the SAFC2.
I think problem2 (and maybe problem1) is related to my "hopefully phantom" knock. Sitting at a stop of I give it some throttle I will read between 10-40 counts of knock. When it get all this knock it adjusts the timin to crazy amounts. 20-30 degrees depending on the knocking... Obviously this has to have some effect on the ECU and fuel trimming
