Are all the VPCs the same with the exception of the internal chip? In other words, can you buy a VPC that is for a MKIII and change the chip to use it with a MKIV?

Different cars you have to change the dip switches, but IIRC early MKIV's use the same setting as the MKIII. As far as that, the injector chip is all you would have to change if you were using different size injectors.
