Are all newer map sensor the same? The only difference being eather 1, 2, or 3 bar type? I'm asking cause the one msd sells is like $60, but there are a few on ebay that look exactily the same for about $20. Any ideas?

Make sure the voltage range is the same.

I would say comparable but not the same. The most common is the GM type and that is what I am currently using. That is probably what you are seeing.

Don't buy any MAP sensor unless you know its power requirements, output range, and pressure range. If you want a stock MAP, I'll sell you one for $15. If you want a MAP that can handle higher pressures (22 psi boost), I can suggest a nice one from Motorola that costs about $23.
