ER comes close to 50 deg celsius-- which is the max allowed IAT for the PC-16. What was ambient?

Default My car limits the g/sec as well. Hasn't seemed to be a problem-- is it ECU related? Or MAF related?

If it is MAF restricted, swapping another MAF that reads higher sounds like the thing to do. If its ECU restricted, we're SOL.

BUT--

If the PC-16 file isn't written to take advantage of higher MAF readings, having a MAF that reads that high won't do you any good.

My problem with the file is its a very poor daily driver. It makes a ton of power at WOT, but everything in between seems mushy. I think when the MAF is maxed out, it assumes WOT and full boost, and makes the right amount of power.

Default apparently it's MAF related

that's odd, as i feel like mine does very well just cruising around -- much smoother and less surging than the 5-bar program.

Default My gripe is 50% throttle feels the same as 90%. Maybe the PC-16 was smooth and slow, and the PDK is

moody and fast?

I would've thought the FMIC would've gotten IATs down below 100F... especially at 62F.

I'm curious about this though. How else can it know what the engine is doing besides the MAF?

Default good info, but his question has to with what the sw does when the maf is maxed...

in any scenario, scaled or not.

In that case there is still fueling via RPM as an example.

Take my car for instance, when I see my 187g/s limit, the software pretty much dumps fuel at a given rpm to prevent a lean condition.

Default it has to. there is no question.

the fact that its maxed out at 187g/s which is what the stock programming maxes out at, means that:

-he doesnt have the pc-16 file
or
-the pc-16 does no maf scaling
