Hey,

Just wondering if anyone has any ideas what is causing this problem. Installed the meth injection and everything works well but as soon as the car starts to get over 15 psi or so my MAF Hz go through the roof and of course throws a CEL for maf high frequency. I thought the cause may be that the MAF sensor is getting wet but I'm not really thinking that is the problem since my jet is behind the MAF sensor quite a ways up the intake. My other idea was that I'm using the snow performance stage 2 kit that uses the MAF signal to set turn on points. I'm wondering if this module isn't back feeding into the MAF signal wire and causing this... I've thought about putting a diode in to stop this but wanted to see if anyone else has had this issue.

I did search for this for almost a half hour and really did not find anything like this so far on the forums.

 

well i dont have the maf tuned kit but i deff think your on to something with the feedback... is there anything else you notice that might be wierd like do you have it set to do something at 15psi if so you might wanna mess with that a little see if it changes anything i dunno but this was a free bump for you...

 

not sure if this will help your problem but all advice will prob help as this time....try tuneing your car for the meth kit to adj everything the right way,...maybe thats the problem right there but thats just my guess

 

I'm not really concerned wether tuning will help things at this point. What I'm worried about is having my MAF read correctly. I just pulled the intake off and it's pretty wet inside so I'm thinking this could be the problem.

well I moved the jet to right in front of the throttle body and it seems to be helping. Although it still throws the MAF high code it seems to be getting better. I think i'll let it dry out and hopefully it will be fine. Has no one else run into this issue?
