Found a fuel saver chip from eBay.Basically it's a resistor type of chip to me and it short the air flow sensor to give ECU a consistent fake signal, as I can read from the instructions. It claims it will add 10-20hp in power and save the gas by adding 5-10mph. So two questions:
1. Has any of you ever used that before? If so, what's return result?
2. How to get it installed on a 2003 Discovery, as mine one is using an air flow mass unit, I can't figure out which wire goes to intake air sensor.

Thanks!

 

Did you already buy the chip? How much was it?

 

I got two of them but found basically they are the same, one for $9.99 and another one $23.99 which claims better performance.

 

I think that you were taken, but I hope that I am wrong.
I do not know how to install them, sorry.
The air intake sensor will be on the airbox, most likely on the top of it.

 

Hey, you got what you paid for, a $10 chip of junk, they don't really work, just a waste of money.

 

I've seen that on ebay also.....Sounded to good to be true.......and for $9.99,ya right.....When a programmer for my old ford was $250...

 

I'd like to give it a try and see. Can someone tell me where I find the two wires from the intake air sensor. I have about five wires from the mass air flow module, but don't which two come from the intake air sensor, that where I need to plug in the chip.

Thanks,

 

You are going to damage your truck and am suggesting no one help you. We are not here to watch people screw up their truck and if you won't take our advice, I won't help.

 

you may want to purchase a new MAF sensor, it's my guess you'll lose yours. they are real touchy. Take Mike's advise...Don't do it... How much gas do you think you would save? she's rolling brick

Don't do it!! I bought it off of ebay, had it in there for a month, saw no results. Took it out.
