well guys my MAF sensor just went out the other day so i got online and searched for the usdm equivelant and found the 94 maxima (vg30de) to be the same part number.... so i ordered a maxima maf and got it today and found the maxima maf to have 4 pins unlike my rb20 one that has 5 pins.... in addition the plug is much larger then the rb20s....

im tryin to find any other options on maf sensors for the rb20det.. any help would be greatly appreciated...

im thinkin that the maf i recieved may possibly be the Z32 maf... after lookin at pinouts.... another question... how bad will my tune be off if i wire up the z32 maf and dont tune it till this weekend??? im assuming the car will run much leaner.... but i will just adjust my fpr and watch the wideband .... any input??

1) what maxima maf are you using...saying you have the maf and which one you actually have are 2 different things. what is the last 3 digits on the maf?2) the z maf and maxima maf share the same footprint so you'll need a maxima plug if you're trying to use it on your 20...3) dont put a z32 maf on the car and expect it to work, it will run lean and cause damage. and dont turn your fuel pressure up to compensate thats just bad tuning.
