I know the D-jet replaces the MAF with a MAP sensor and is good for 400+bhp but what benifits does the D-jet have by doing this if the power i plan to gain is below the magic 400bhp ???

cheers

none really the only reason you replace the maf sensor is because it cannot measure the amount of air being taken into the inlet.

so if you are just doing 350bhp ish then they will be pretty much the same

I guess maybe the only other benefit is that it will be easier to get closer to 400 without the restriction of the airflow meter.

Oh yeah, and it's not so easily upset by dump valves.

Cheers guys, looking at getting a 2nd hand L-jet with commander and should see a nice improvement w/o having to rob a bank and seems good value.

ps. If anyone has one they want to sell on as they maybe going the D-jet route please PM me :D

the pressure drop over the OE MAF is high. therefore using a MAP based ecu you can do away with the MAF and make more power at the same boost level.

the MAF system is easier to tune though, if you are gonna do it yourself and will do 400hp.

Hi Oli

Why does it make it easier to tune ???

Also i find the D-Jet alot smoother in the way the car drives and pulls as with my old Maf set up the car was more jumpy and stuttered on lift off
