ISR DECKPLATE question

[spongerx]

Ok. I did the ISR and Deckplate mod a while back and also installed a True Flow filter. My question is this: doesn't the computer compensate for the extra air flow and in a way put it back to stock running condition? Wouldn't one have to install a chip to set the computer to stay where you want it for better MPG and performance?

When I first did the mod my 4runner was nice and loud and "asked" me to change gear at about 2500 RPM, seeing that I have a stick shift. But now, if I'm lead footing it, it wants me to change gear around 3500 RPM, and I don't get that sweet sound until I get into those higher RPMS. Any thoughts?

its more about the air getting into the engine easier IMO.

What your eliminating, is the resistance of the stock airbox, and the resonator.

Oh and your ECU does automatically compensate if more air gets into the engine. Thats what your MAF (mass airflow sensor) does.

Thanks for the reply. I guess thats part of my question. If the Mass Airflow Sensor is changing things, does that mean that I will not get the full advantage of the mods?

Did you try taking out the EFI fuse and reinstalling it to reset it, so maybe it will relearn how it once was?

I think I did that at the very begining when I did the mods. Maybe I'll try it again just to see if there is any change. But to be honest, I would assume that even after resetting it, it would still adjust itself to the new amount of air flow.

The ECU remaps for the extra air and it will stay that way unless you close the airbox back up.

The deckplate mod isn't allowing a huge amount of air so the ECU can easily compensate for it.
