Pocket Logger what is normal

[hellotbone]

I just started logging my 2g what is concidered normal for the values? Im hitting 20 * timing at 6000 rpm is that normal? I also want to know what o2 sensors should read and fuel trim low and high I tried a search but didn't find what I was looking for.

Also how do I do a knock count with a pocket logger on a 2g? I also want to add when at a light my 1st o2 sits at 0.00 v and 17% my second 02 sits at .84 v and 17% what do they mean? Sometimes the first reads .02 v I just started this morning so It may move around more?

20 degree's timing is good timing. Usually you want it in the high teens at the end of the RPM range.

O2 readings should be around .94 to .98 volts. This is at wide open throttle of course.

At idle it may not read much. As long as its working while you are driving, it should be fine. If its not logging the first at any RPM, then its probably dead.

2Gs can't have the knock monitored with an OBDII datalogger. The timing is a raw value ( not a numerical count, ie 7 counts of knock ) and can't be read by the logger. A DSMlink can monitor knock, but is not really a piggyback or a pocketlogger. As long as your timing curve at WOT is progressive and peaks around 17 to 20 degree's, then it should be good. If the timing is not there ( really low for an RPM, like 5 degrees at WOT at 6000rpms ), then it could be real knock or phantom knock.

Good to hear. I guess you got your money's worth out of that logger ( saving a trip to the dealer ). Hit a dyno sometime and post some numbers.
