MAFXtender Users. What DIP setting should I use for around 510rwhp?

[Dominick32]

Anyone that is using MJ's Mafxtender, what do you have the DIP setting on?

Would you use the ONE DIP SETTING that extends the MAF range to 5.0 - 5.5 volts?

Or the TWO DIP SETTING that extends the maf range to 5.5 - 6.0 volts?

I plan on installing and tuning my 4# lower setup tomorrow and I am curious as to what setting I should use.

Thanks,
Dom

Start with the first setting. This should work fine. However, if you end up pegging the meter still then go to the second setting.

The first setting is:

SW1 - ON
SW2 - OFF
SW3 - OFF
SW4 - OFF

...and this scales 5.5v down to 5.0v. This should be good for around 590rwhp.

Ideally, you should use the least amount that you can. That way your low speed MAF_transfer_function retains better resolution & drivability. If you find that future mods cause the MAF to get close to 5.0v again, you can always change to the next setting.
