fcd what does it do?

[mazdaspeedwerx]

I just bought an fcd from a forum member and I have installed it corrrectly. but what does it do? I ran at the track tonight and I thought that it would not let my engine cut out at 15 psi but i was wrong . is it just for my engine not to cut fuel at a specific speed or is it so my engine not to cut fuel at a spcfic boost setting? I dont really know, and dont say that I am not supposed to be boosting past 9 psi because I know. I really want to boost at 15 psi and any info would be helpful except for the bullshit that I shouldnt be boostin past 9. I know that I will blow my engine at some point and I REALLY DONT CARE SO DONT POST THAT SHIT IF THTS ALL YOU HAVE TO SAY.

try adjusting the hex screw on the fcd ...turn it clockwise for higher boost i think....try it out.(bang)

chill out.

your MAF is still seeing 4.6V+ that's why its cutting. search alittle and you'll figure out how it works and how to adjust it.

I hope you blow your motor.

I belive the MAF is maxed at 5.0V correct me if I am wrong someone.

[Moeed]

yea its probably not adjusted correctly.

thanks for the help guys. I will look into adjusting the maf. also from past experiences posting on here there is usually more post telling me how I am going to blow my motor than actual help. I just didnt want to have to read through all that crap just to get to a solution. thanks again
