Hi am I right in thinking that the MAP sensor on a AHY engine is built in to the Ecu. There is a vacuumed pipe running to the Ecu next to the sensor cheers ric.

Don't you just love auto correction sometimes?!?!?!

As to your question....I would assume some companies would be able to do it, but not certain it's a DIY job unless you have good soldering skills.
Taking the ECU apart is a daunting task, as not getting it back together and sealed again means it will last maybe 3 months!

You must be right on the edge, as both my 2000 vans have had the newer ECU.
