When I go to publish new MAF scaling, I get an error 'MAF g/s Values must change at a positive rate'. All of the suggested cor % values are negative or 0.

I'm on OFT v2.066 stage 1 91oct tune.

Here's a recent datalog, FWIW (probably very little).

Thanks very much
1. Use the VGI utility not the yikes spreadsheet, the vgi utility is very easy to use, see links below

2. If the AEM intake is the one that comes with that electronic device to fool maf sensor get rid of the electronic box and just scale maf without it.
3. use AFR for your measurements not Wideband AFR unless you have installed the correct wideband senso/controller in the second 02 position
