It should be - but my tester had an O2 sensor issue (or something).
If you set up the Manifold scale in load like the AP; all else being equal your fueling will work the same - the air calculations; Like Horsepower etc will be off - but the actual tuning part should work. - Key word SHOULD; haven't tested it yet - but you can play with it if ya want to.
I am waiting on a MAF/Load based EMS (like the AP) to actually verify this information - and make the appropriate changes to my software so all the stuff works.

please let it work and can someone tell me how to set up Baseline for my car so I can try and start the tunning process. I'm not sure where to get a lot of the info it's asking for. I have a map from jeff but it goes crazy lean in first and second gear at weird times and this is making me super nervous
. I'm not getting much of a response from jeff so I would like to get the problem resolved before I go boom. Send me a pm and I'll send you my phone number if this will make it easier for someone to help me set up the info needed to get started.

I'll be leaving for Newfoundland again in a few hours; sorry.
BUT I'll write a real user guide during my 3 days on a plane (seriously - THREE DAYS).
In the meantime - you guys need to help each other - the info is publically available; just have to know what it is.
Injector Sizes - Max Duration all that stuff; just ask what you need and someone can help.
There have been like 200 downloads of this thing; so others are using it.

For NA - leave it at 1 (that will not modify any temps for boost). It doesn't actually affect the tuning fuel side - it is more for knowledge of the theroretical heat gains and later when I add the Efficiency Charts to the software; it will be important.

Most common min injector duration is 1.7ms - since it takes some time to open.
Max injector duration for us rataries is safely set at 16 ms
Duty Cycles I use are .5% min and 95% max - a lot of folks say never go above 80%; your call.

I don't know those two for the stock O2 sensor and the AP;
but if you make a log; let off the throttle (to go into fuel cut) and see how long it takes to go full lean); that is a good guess to AFR latency. For my Autometer it is 560ms and my logging interval for the EMU is 20 ms.

Basically I need two things;
Sampling rate of your EMS (Accessport in your case); how often it logs the engine.
Delay from the engine's AFR and when your gauge catches up. (Latency)
With these two things I know how to line up the AFR readings and the engine readings; since they all have to be shifted to account for the latency of the AFR reading.

this is my timestamp intervals according to ATR-10:36:04.615, 10:36:04.725, 10:36:04.834, 10:36:04.943 -109 millisec
From WOT to full lean the timestamp went from 10:49:02.057 to 10:49:03.586. so my AFR latency should be - 1529 milliseconds
and how do I get my accel gamma.

Let's not worry about accel stuff until we all get a warm and fuzzy witht he basemap.
You have two scales (PSI and RPM) - together they make a 3D map right? Well intead of using manifold PSI - use load and the tune should work out just fine with the AP.

I haven't turned the MAF scaleing window on there yet; but it is in the software. What it does is measure the Airflow directly by using the fueling information (which is pretty exact since we know that 6ms of duration is always 6ms) and the reported AFR. If you have a log that shows AFR, MAF voltage and fueling info - I can reverse engineer and get you a table that shows the Airflow value based on either the Scale of RPM and Load - or just by voltage (all using averages). So you'll get a table that shows x amount of voltage = y amount of air.
Will that allow you to scale it correctly?
