There are some benefits to Pectel software dont forget folks.

What most dont realise, is back in the 80's Pectel reverse engineered the software that runs the engine and totally rewrote it to suit their own plans, including the fantastic Pectel serial comms output and datalogger as well as water injection drive. Like it or loathe it, the software itself is great, if not a little limited with stuff i wish to do nowadays

They then wrote a front end for it called "IEMS" so that their customers could directly access the maps and map it, and they made it very user friendly indeed, anyone with even an tiny amount of engine knowledge could understand what the maps did and adjust them. In the 80s, this was a serious breakthrough and gave them a real leap forward in the mapping stakes.

What they then did, as stage 1 of their protection plan for teh new idea is design a system that would scramble the finished map, so it wouldnt run a car at all. So when you had done your map, you saved it to a binary form for teh Eprom, but it saved it as a kind of jigsaw, so when you plugged the chip into the ECU, no go, it wouldnt run
Stage 2 was to design the ecu hardware that then decoded the software again into a format the ecu could understand. This is now known as the "Pectel Board"

When the Pectel software was run "Through" the Pectel hardware, it would run just fine.
Therefore ensuring, that even if some gimp came along with a Eprom copier, they couldnt benefit from al Pectels hardwork without buying a Pectel board as well, which is where the profit was, thus protecting Pectels investment and securing their future somewhat. Very clever indeed, and a system we have all pretty much adopted now throughout the industry.

Hope that helps people to understand the mysterious "Pectel Board"
