Fuel trim Logging
 

Hi,

My car is an Evo 9 EDM, with full BBK turbo, M2 cosworth cams and 1000CC PTE injectors.
ROM : 88840016
I uploaded "88840016-nlts-mod-v2" in order to have "knock cell".
I discovered later on that it has the rear O2 disabled :).
I tried to log my car with evoscan 2.9 but the fuel trims are always "0" :mad:.
I've read in some threads that if the rear O2 is disabled then the LTFT won't work.
I checked the periphery0 (FAA) bit 1 is "0":confused:.
Please advise of a solution in order to be able to log the fuel trims without loosing the knock cel (return to the original Rom).:helpme:

Thanks in advance

change it to 1, change the tephra option to simulate rear o2.

then, make sure you are not in closed loop all the time. (open loop load tables should look normal)

thanks for the reply;
change it to 1 --- Ok:thumbup:
change the tephra option to simulate rear o2 :confused:(can't find it )

then, make sure you are not in closed loop all the time. (open loop load tables should look normal) --- do you mean to alter the tables in "open loop disable below" and "open loop enable above" ??

Tks in advance

v2 does not have the "Simulate Rear o2" patch.

Will the 88580714 resolve the problem ?
Cause I've checked it yesterday and it I was afraid to upload it cause the rev limiter was set to 114 so probably there's something wrong in the xml file ..?
