Perrin CAI MAF Scale

[Kodename47]

I know that the 3in intake scaling can be found here:
http://perrinperformance.com/i-14448...-fr-s-brz.html

Does anyone have a basic scale for Perrin's normal intake or is it close enough to stock scale that the basis can be done from that? I've tried looking but no success.

it would be the last post on that page or post #44

Thank you very much!!

I'll be curious to see what results you get. I scaled mine and am running a little lean.

Cheers for the heads up. I will bump up the scale by a couple of % so that it's running richer and then reduce it if needed.

I posted this somewhere else, if you guys make a different MAF curve that seems to be working better, send it to us to test out, we'd like to see it, thanks!

Here are my torque logs for the past two days using the scaling provided by Perrin for the 2.5" Intake. I think the MAF looks ok, but please let me know if you think anythings off.

Is there a way to record throttle input, fuel trim short, and fuel trim long? That's what we'd need to see to make sure it's running right.

Is the highest sample rate really one per second? If it is, it might help to delete the some of the line items that aren't needed, GPS time, the G x, y, and z.

@moto-mike just finished tuning my 3" perrin CAI for my Innovate SC. not sure if this is something that would be beneficial for him to share though.

I will log those tomorrow and re-send. Not if I'm running the fastest sample rate or not...

Here is the requested data at .1 seconds (increased from 1 second). If its missing anything, let me know and I will connect my OFT to log it.

Milhouse, the log looks good to me. Just normal fuel learning in there, and no high trim levels, so looks like you're good.

Great. If you want my Romraider file to copy the MAF scaling, let me know. No other changes in it.

And thanks!

@Kodename47 did you ever end up doing your own scaling? Going to do some scaling with VGI tool next spring before hitting the track
