Get me some data, and I'll let's take this out of HPT's incompetent hands, and into the 21st century.

I agree. When two independent methods arrive at the same solution that gives us a lot of assurance.
But when MAF signal is too noisy, you can map SD-derived airflow values onto the MAF...
The moment anyone says 'sometimes it works' what they really mean is 'my tuning tools do not allow me remove the noise, or isolate the good parts to work with.' never stepping outside of HPT limits...
The formulas that HPT allows us to have are 'contextless'. What I mean by that, is they do not let us deal with (unless they've changed things and I missed them) data from any time other than right...
nope, there is NO way to tune 3rd gen IAT+ECT+BIAS model. <-sarcasm

does it always happen in a similar MAP,RPM range?
Matlab with my own code
I dunno, havent used HPT in years, but this thread suggests there's discrepancies.
Highly suggested exercise to verify your math: run the stock numbers through the model (you think) the VVE calcs use. if you end up witha different surface, then the model is off.
@mowton, he said SD, you're giving him MAF derived airmass. plus, might wanna mention that your conversion assumes number of cylinders.

I have beaten it to death 8 yrs ago. What do you need to know?
Speed Density is MAP driven. Thus the elevation changes (and any other conditions that affect air pressures) are calculated correctly.
We know what they do, they weigh the different reaction of airflow to MAP and throttle changes, per VE zone. This estimate model establishes few things:
1. MAF is primary source of airflow
2. ...
I would test with the effective TB position, whatever the actual PID is actually called, not the raw inputs, but the post-modifiers/smoothers/filters. I think the regular TPS on a ETC car tops out...
@Barum, which value are you using for TPS? There's a lot of them to choose from on ETC cars (which is just about anything these days). This would definitely contribute to the imprecisions if you're...
http://www.hptuners.com/forum/showthread.php?47513-Prediction-Coefficients this thread has some very interesting discussion going on, if we figure it out, we should be able to sway blending toward...
The easy way to verify if your run full SD, is to set the MAF table to a silly (but legal range) value like 1g/sec across the full range. If any of that is taken into consideration, obviously the...
so disable the codes for MAF
Does the old 'fail MAF' method work?
Lots of throttle and steering input resulting in power reduction? Sounds like stability control to me.

I have, ages ago, that's why I'm telling you where the problems are going to show up. I'm not pulling them out of thin air. Oh yea, and it was all open source ;)
'throw the table in'...which table? 'the' implies like i supposed to know which one you're talking about.
Generating surfaces out of coefficients is just addition and subtraction, that's not...
We already got the maths for it, we'e had it since 2007, nothing to uncover there. but it would be nice to verify.
