the thing is, the spreadsheet does not work on cars with altered maps/injectors.
I have logged a few cars usin gthis and the figures are bizarre in one extreme and believable in the next..
eg: on boost afr of 18 is'nt likely, but was on a k03s'd car by another tuning Co
Not sure I would want to rely on a cal'd figure..
He has Zeitronix, can log actual afr against rpm against boost.
If its leaning out, it either physical delivery issue (pump, lines, FPR,injectors) or map is not asking for enough..
Trying something like lemmiwinks, custom settings uni_settings type programmes will allow some channel adjustment.
Sounds to me a mix match or parts which do not work with the map as set.
Remap it, back at HQ of who mapped it originally once convinced all other mechanical aspects are correct of course
