LS7 maf and 411 ecu

[freshda9]

Sorry i know this may have been asked around several times before; but i cannot find a clear answer.

So the popular 0411 ecu I know can work with the Slot Maf. I notice their is no patch for the 0411 ecu unlike the E40 to extend the Maf to 15,000hz.

1. -So is their a scaling factor i have to perform to utilize all 15,000hz?
2. -Most say use an external IAT and plumb it into the intake system as the IAT in the Maf will not read correctly by the 0411, correct?
3. -Do i simply install everything above and start tuning the Maf curve accordingly or is there more to this?

^why not go MAFLESS and be done with it.

Because im not asking about my personal vehicle; and have no control over what may be brought to me. Yes a speed density tune would be great but there are also plenty of great maf tuned vehicles also and with the majority of things speed density isnt always needed.

You can't scale the frequency...you can scale the airflow values entered in per frequency...but that's it.

If you need to get the frequency lower, you need to put the MAF in a larger diameter tube.

Gotcha!
