Map Fooler and EBV fooler

My TS Performance chip is arriving soon so I need to fool the MAP. Plus Im getting rid of the EBV.

I know you can do it yourself by putting a resistor or diode. But I wanted something that plugged in cleanly.

dfuser.com sells them but $40.00 for a MAP fooler plug is pretty steep. Does anyone else make or sell them for less? Thanks

There is a zenor diode mod you can do, that if I wasn't so tired I would explain. Alabamafrog has posted a ton about it. Search for it, you'll find it.

Other option to fool the map sensor is an overboost annihilator. Check with itpdiesel for that... I know theirs is cheaper then 40 bones.


The EBV if you really want to delete it then you have to pull the turbo... do you really want to do that?

thanks man I will check with ITP. I have to pull the turbo anyways to change my leaking orings on the pedestal. So I was going to order a new pedestal without the EBV and gut the part in the turbo.

out of curiousity....when you use this MAP fooler and it shows a max of 22psi to the ECU. What happens when you're boosting more like 35psi how does the computer add the right amount of fuel when it thinks theres 22psi instead? If you add bigger injectors to compensate...then it will run rich as hell idling unless somehow you can pull back injector pulse width at idle or non boost rpm range.

Im coming from the gas engine world so please bare with me!

With a programmer...your already "overfueling" a little...and the MAP sensor isn't good for anything over 22 psi anyway. Diesel's operate on compression ignition so you can't "lean it out" like in a gasser. If you don't have enough fuel...it'll just shut off. Like if you spray too much nitrous...9 times outta 10 it will just shut down. Now if your spraying 500 hp worth in a stock motor...your risking popping HGs. I dunno if I expained it right...sounds good to me though.

oh ok I see because of the compression ignition there really is no dangerous lean conditions..just more of the damage for higher EGT's?

So am I right to assume these diesels arent as accurate or dont need to have as accurate fuel to air mixtures that gas engines do? Im so used to seeing Mass air sensors, speed density, o2 sensors etc.

How do these diesels run their fuel maps? Is it based off the MAP sensor pressure or just throttle position or both?

With the gas engine throttle position is averaged along with the engine load map. Meaning 10% throttle doesnt always yield the same amount of fuel being injected. 10% throttle in 1st and 3rd gear gives different pulse width as the computer senses more engine load from the amount of air passing through the MAF. Of course I'm probably complicating this more then it really is.

If I'm correct...diesel's use peddle position, intake air temp, boost pressure, and a few others that I know I'm missing to regulate amount of fuel injected. Though I am NO expert.

I would say to call either tony wildman or dp tuner for a real good explanation and then post what was said for future references. I would give it a stab but I don't want to make an as$ of myself.

I use the ITP overboost annihilator and I can tell you that my trucks PCM sees 22psi when it is making over 45psi of boost. It works quite well.

I have a TS 6pos chip & I installed a air pressure gauge in front of map & behind my boost gauge on 140 hp setting all stock eng w/af 4" exh it pulls 32lbs boost no cel.

I am sure you know this but at 32psi of boost your stock turbo will not live that long. It is out of efficiency after 28psi and is not made for over 28-30psi. I killed mine in 3 months of 30-33psi.
