whats going on guys i need some info if ur willing to help. my mafs went bad on my sr and i had to switch it out about 2 weeks ago i put in a used mafs from a single cam ka like its called for and just today i blew it out. i drive this car daily so this wasnt the first time i drove it since i changed mafs's. what might be the cause of this?? the mods i have are just basic turbo back exhaust front mount and fuel pump. i have been running about 13 to 14 psi. i am going to buy a z32 mafs but is there any other mods i need to do in order to make it run using that?? (tuned ecu ect.. . . ) and what might it be thats making it blow out? thanks alot guys and maybe girls

If your using good known maf's and they are going out you should probably check your wiring first. Something it causing them to short out OR you just have a bad string of maf's. I had the same problem a little while ago. I am on my 2nd SOHC KA maf and I keep my stock SR one for backup. If you plan to run a Z32 maf, you need at least a SAFC if not another method of tuning.

 

check your wiring..

people have gotten bad mafs in a row before, but mafs generally don't just go out one afte rhte other.. clean all of your electrical connections, make sure you dont have any shorts

try your bad mafs in another known good car!
