No you cant just hook up a mbc and crank it up. Your car/ecu isnt "smart enough" to compensate with added fuel/timing adjustments to make any extra boost over stock useful. 00+cars/ecu's can get away with it by doing the diode mod because there is a map sensor- and the ecu will compensate. If you just crank the boost up on a 97-99.5 engine it could cause very very very bad things. Like severe detonation. Get a chip.

 

Ok, thats what i thought. [:@]

after bypassing the n75 with a mbc is it a good idea to plug the 2 prongs on the n75 or leave them open?????

 

I have mine open still, but youprobablyshould cap them

 

just put a small peice of hose over them and clap the ends

 

soooo what i understood from all this, my setup should be...(2000 1.8MFWD)

DV= 710N
diode= 4.3v?
MBC= bleed/ ball & spring combo? was thinking either

http://www.joepmbc.com/mbc.html the xz one
and not bypassing the N75 for smooth, but strong, accel.

also getting a boost gauge and possible A/F...

sound pretty solid?

 

that sounds good. you want a bleed type mbc cincytt says they are the best for your car. i have never used this type so i cant say forsure.

 

awesome thanks

 

That voodoo one is the knock off of mine and my mbc works really well.

 

should i get the 4.3v or the 4.7v? does it really make a diff?
