Hi are the pin outs the same for the IAW 6F.SB & IAW 16F Ecu's?

I have bought a Mcrich Chip for My 1100cc Punto onlt to find it doesnt fit in my ECU as I have the IAW 6F.SB not the IAW 16F, I have found a couple of 16F's for sale on Ebay that are very cheap, if the pin outs are the same lll just buy one and fit the chip to that

Cheers

Tristan
