Hi people.

I am hoping that someone will reply to this post as the last one i did i havent had any luck or replies.

what it is that i initialy had problems with what the lc-1 wideband sensor readings in logworks was saying compared to what the megatune software was saying were totaly different by a quite a bit.
i.e. like in logworks it will read 14.7 but then megatune said 12.8 ish.

this problem has now been fixed BUT when i am going to do a log using megatune and then play it back in the viewer, the values are miles out... like 14.7 in megatunes window is then about 12 in the .xls file.

How can this be.

has anyone got an answer for this ???

also has anyone got a GOOD O2 log of their engine i can have a look at to compare with mine . as i am finding that when i had the narrow band one the readings were a log flatter than what the readings are in the wideband setup.

please if anyone can help then please do.
thanx
davey

Davey,

Is this MS-II? If so, have you calibrated the AFR table under tools in MegaTune.

I believe the LC-1 has some options for outputs, and these need to be chosen correctly. There are a number of threads about how to use the LC-1 with MegaSquirt, search for advice in those.
