My tuner added the entry wrong in my ECU file for wideband. Anywhere to just recalculate the log to find out the wideband?

Here is the entry he added:

WBAFR           , {wideband AFR}                    , 0x381116,  2,  0x0000, {WBAFR}   , 0, 0,  0.014688064,  -7.35, {logging wideband AFR}

Correct one:

WBAFR           , {wideband AFR}                    , 0x381116,  1,  0x0000, {WBAFR}   , 0, 0,  0.014688064,  -7.35, {logging wideband AFR}


Note the "SIZE" of two.  What is this "SIZE" parameter?  and how can I use it to derive the true AFR value?  I would just go out and simply relog but there is only a window of time I can do it because the traffic/cops.

8 bit vs 16 bit word (1 byte vs 2 bytes)]

I highly doubt 1 byte is the "correct" one.

Sorry you are right. I posted it wrong. 1 is wrong. 2 is right. Anyway to convert a calculated AFR?

I emailed you about it but it may have not sent. Open the .ecu file and change the size from 1 to 2 and you will be good to go.

You can't convert a logged 8-bit value to a 16-bit, since half of the data is missing.
