New MAS, need chip reprogrammed?

[Limited Ex]

I have been wanting to get a bigger MAS, but I read somewhere the other day that if you have a new chip and get a new MAS that you would have to have it re-programmed to compensate for the increased air flow. Anyone know of this? I do not want to have to send my chip back to have it re-programmed.

You don't necessarily need your chip reprogged. You do however need calibrated electronics for the MAS.

i the only time you have to have it reprogramed is when you are using a mass air that is not the correct calibration for your truck. like using a mark VIII mass air or lighting mass air.

So a 66 or 70mm, not sure what size, would be fine without having the chip redone?

As long as the electrics on the MAS know it's a 70mm Explorer MAS (66mm is a TB size).

I'm awful at keeping numbers where they need to be. Wouldn't the sensor on the new MAS tell computer what it needed to know?

 

[Alec]

yup, as long as you buy one meant for the X with the stock 19# injectors. IMO you have to make sure what you're buying cause if it's not right it wont work.

Alright cool, I'll be sure to ask some questions before I buy. Thanks for the info!
