MAF Alternatives

Does anyone know of an upgraded MAF or alternative we could use for the MS43 (3pin). Mine is maxing out at 4800 rpms....

Perhaps from another vehicle. I dont want to scale it down, I want more air...

I had the same problem. I test currently an Audi RS4 MAF . This works so far, but the tests are not yet complete. Others here want to use a HPX MAF

You need to do the maf hack mod That enables the ecu to read/understand 2048kg/h.

On my actual setup I`m reading 1150 kg/h at 5500rpm. The Audi RS4 MAF should be able to read much more. I will give more Infos when they are proven.

Came across this and wondered if we could adapt it into our MS43 platform. I do know the HPX maf exists, just taking a a shot at a cheaper, more available option. This is an 85mm MAF sized for the 7.4L american trucks. It is also 3 wire. I am guessing we should be able to make it work if we find the MAF scaling table, correct? I was searching the modified truck forums and some of those guys have 700+ hp on their stock mafs (this one). I am conducting a search for the scaling....

They are abundant and easily replaceable....So, what do ya think...doable? (Daniel, Alex, Paul)

Dont want to reinvent the wheel, but for a fraction of the cost new, and even cheaper used, I figured its worth a shot. I have seen these used for $35. That beats $250.

Still havent been able to find the MAF scale for it.But if its as simple as getting the hardware and finding the MAF scale...I say why not!

Not looking good....

But I have seen the PMAX here for a bit less. Right in line with the cost of the ebay MAF

I personally think when you consider the cost difference of the HPX, and the fact it comes calibrated with transfer data, and the fact that a number of people have it working correctly with MS43 (and these people are very helpful and always offering assistance on this forum), the HPX would be the less time consuming option, and cheaper to get working with the car, regardless of purchase price.

Yea, true. I originally saw the PMAX for $250...Now it appears to be $119...so I would have to agree. But, all it takes is one person to get the other working and we would have another option. Its more trouble than its worth because it appears as if they operate a tad differently and it still wouldnt read as high as the PMAX.
