    Yep there isn't any crazy steps in it, if it's not my VVE then where should I be looking to get my idle AFR back closer to the commanded? Or is it a case of leaving it since it idles happily at these numbers.

    I'm not sure what I'm doing wrong but I cant seem to get this VVE process working. it either causes huge peaks in areas and huge dips in others unless I use the copy and fill process, but when I use that it seems to change my logged data to much and don't get the desired effect in AFR? I have tried to attached a log but it wont so here is the latest tune file after applying this BEN Map.

    Found my problem, if you set map precision to 3 any numbers over 1 become .025 ect if it's set to 2 the number shows 1.02. So every time I would paste and multiply it would cause issues. In the mean time any rich spots have been sorted but all the lean spots never changed as they would multiply by .025 cause a huge hole then get smoothed out once I would gem coefficient and vve

    Yes, all E38/E67 and the general concepts apply to the E78/E39/E39A/E92 with some minor tweaks.

    E92 requires a calc pid for MAP:BARO ratio (which is used to reference the axis of the VVE tables)...

    i.e. define CALC.MAP_BARO to be {SAE.MAP.kPa}/{SAE.BARO.kPa}.

    Make the MAF fail (i.e. force a MAF DTC immediately (you might have to increase the very low end of the MAF so engine can start and then throws a MAF DTC))... and go from there.

    Oh, yes, there's a log joining tool somewhere, I don't remember where it is... if you have multiple logs, the joining tool joins them together... just try it, you'll see how it works.
