HPX MAF is a direct replacement, correct?

mainly:

1- disconnect the negative lead (battery)
2- remove the stock maf
3- install hpx maf
4- put the negatove lead back on

 

^ for that Question. Yes, it fits perfect with stock housing.

 

+1 it fits the OEM bung fine. As others have said, your car need to be tuned to use it though.

 

im interested in the maf as well.. let me know when u fix it.

i hope all go as planned.

 

Hmmm...interesting...91 isn't that bad then. No enough to cause yours numbers to be THAT low.

 

i might end up doing this..

 

Thanks guys.!
i'll update you on how it goes.

 

o btw, ECU threw a SES "P2A00".. it's to do with the O2 sensor, but not sure if the sensor itself is malfunctioning or something else triggering it.

 

another SES....

P0300 now.

 

the good ole' random misfire code

 

Hold on...So your tuner tuned your car without MAF sensor? So which just tune with osiris? If that it is...i take it back about huge leak...I have feeling that it is the sensor.

And code, if tuner knows how to fully control osiris, you shouldn't have any problem after retune.

 

so, what's next??? what should i do about this?


sorry Chef, i didn't understand what you're saying.. can you rephrase please?

thanks

 

SES P0300 went away by itself this morning!.. when i started the car it wasn't there!?

 

Opps, sorry I was little rush when I wrote last post. First dyno tuned, you mention you making really low whp I was asking if that's done without HPX sensor.

 

we didn't do dyno tune.. but we did a dyno run without HPX sensor. and yes, i was getting low HP (15whp max).

but again, the MAF maxed out @ 5400 rpm, and i don't think 15whp is good for just to 5400 rpm.

i'm waiting for Vince to send me the HPX.. hopefully i get it by end of this week so i can start tuning the car again.

 

Ok I hear ya. Humm interesting.

 

Update...

mechanic done a boost leak test, and it was holding upto 13psi. (i wasn't present to witness).

he also replaced the belt with a shorter one.

on my way back home, i noticed the boost looks ready at half throttle.. i stepped on the gas and saw upto 4psi at 4500 rpm on 3rd gear. i didn't wanna shift past 5000 rpm because that's where the MAF max out.

i'm not sure if i should notice any difference before a tune.

thoughts?

 

you wont notice any difference in boost levels before or after the tune.

 

hmmm.... shouldn't i see a greater psi with the correct belt size and being tighter?

 

4 psi at 4500 rpm sounds normal
