    You can pick the cheapo ones up off ebay as you only need the housing so you can swap in the sensor from the standard maf.

    won't the 850's maf surface area be under size for the housing then, or do you then adjust the scaling to allow for the smaller surface area of the 850's sensor to the diameter of the maf housing, else I could see some massive leaning out is due to happen as the throttle gets opened.. ??

    There is a program (available on the M4.4 wikia site) that adjusts the scaling in the ecu to account for the increase in housing size. Basically the stock values are multiplied by 2.24 for the 3.5" MAF

    Oooh, it's been a while

    So I haven't been happy with the fuelling settings of the ecu. After some research it turns out the VXR 470cc injectors aren't 470cc they actually flow the same as the 'big greens' at approx 440cc. The only difference between the two injectors is the greens are 12ohms impedance and the vxr blues are 14.5ohms impedance.

    Not that much of a big deal though as they were cheap enough and they flow the same as greens.

    Just need to change some settings and hopefully that will sort things out.

    Next project is getting the 3.25" MAF to fit (unfortunately it's not a 3.5" like I first thought but still better than standard)

    Nice to see an update Dave and I look forward to hearing how you get on with the new MAF.

    Also been getting on with the epic that is the 320mm brake conversion.

    The calipers and brackets are a bit rusty so I made my own blasting cabinet out of a huge IKEA storage box.

    Got one bracket done and sprayed up, now to do the rest...

    I'm using a 20/40 grit Garnet media. Not a perfect finish but gets all the rust off.

    Here's my bodged blast cabinet

    Fair do's Dave, looks ok and is a fully functional bit of home made kit, can't be classed as botched in my book, nice work Sir.

    Thank you

    But now my air compressor is dying (making funny noises and slowing down)

    There's a local shotblasting company so may see how much they charge just to get it done as I've got to move onto the next stage of the brakes, brackets
