Can someone explain Pectel?
Ok, so Weber Marelli make the IAW used by cossie's. You've got L1,L6,L8 & P8.
Where does Pectel come in, who are they, and why are they needed. You hear of baby boards etc, do the IAW ECU's have an I/O port internally?

As you rightly say, Pectel did NOT have anything to do with the original ECU, that was made by Weber marelli in Italy and as std incorporated a lamp output that was capable of sending out flash codes to indicate errors. IE: 10 flashes = CTS. ok?
Pectel, are a company that (i believe) formed in teh 80s and soon became masters of the Weber marelli Ecu systems and their affiliated soft/hardware. Back in the day, the cosworth was fast becoming the engine of choice for fast road and motorsport but the hurdle most couldnt overcome, was making the ecu's run teh modified engines PROPERLY.
Pectel designed a system that would allow people to map it easily, with a DOS based mapping interface. They perfected the mapping and run software and it worked flawlessly in the ecu. The run software like any other, is the "Opertaing System" that runs the hardware that you know as an ECU. PC buffs can liken a chips software to their motherboards BIOS.
This is where Pectel differs from a company like myself, we will make the existing run program do what we want it to do by adjusting its maps and calibrations and then burn the modded program back to a chip, Pectel cleverly designed a whole NEW run software system that bore no resemblance to teh original at all and could be adjusted map by map using the mapping software they supplied to their customers(Pc buffs.. a bit like teh difference between, Award and AMI bios. Both totally different, but with the same end result)
What pectel then had to do was protect all their hard work:
The mapping software (Called IEMS for L1 = 8 and IEMS P8 for P8) was simply that, a software program that would be ripped off in no time. They programmed a dongle for the parallel port and that would ward of most thieves, but still made it a one time only purchase, not exactly business idea of the year, so what they did then was, back in its day, quite unique...
They altered the mapping softwares "Save" program so that when you had finished your maps, and saved them ready for burning to a new chip, the program "Encrypted" the file so it WOULD NOT run in a marelli ecu.
How did you get it to run?
You bought a "DE ENCRYPTION" or "PROTECTION" board that would translate the encrypted message from Chip to ECU. This hardware was copyrighted and only available through Pectel. Now they had a viable product and everytime someone made a new performance chip with thier software, even if they had ripped it off, they had to purchase some hardware from Pectel before it would run an engine. The board is now widely knows as the Pectel Board.
Ingenious.
Hope that answers your questions...

Thanks Stu - that makes sense. Where does the Pectel board plug into?
How about today - do u still use Pectel's software, or do u work with the marelli program?
What did Ford do for factory backed teams in racing?

No we offer an amalgamation of the 2 systems allowing you finally to have full closed loop with the benefits that Pectels new software offered such as the serial output and error code streams.. +more.

Don't forget that Pectel Control Systems (Pi Research) still offer a large range of professional motorsport ECU's (www.pectel.co.uk)..

Top info, thanks. Not having a cossie, never really thought about it, but it makes sense now.
So who makes the software for editing marelli maps?

Testing the future
a babyboard is so called because it's smaller than the mainboard of the ecu that it's connected to (the parent that does the most work). it may also be called a daughterboard 
and yes, in the case of the pectel babyboard, it's function is to de-encrypt eh run program and maps in the "chip"
pectel management - not really as in pectel made ecu's such as they have available now like t2, t6 etc. but i guess that they needed to protect their maps somehow

I don't think many Pectel orientated tuners have bothered with that sideof things - indeed, the same could be siad of most Cossie tuners, until Stu put the time & effort in to develop his lambda package......

Good simple explantion there stu
The webber pectel system was developed for ford motor sport at huge cost.
so back in the 80's and 90's the retail public had the ability to purchase serious software for their road car.
Stu has also protected his maps with an encryption boared to stop the rip off brigade and who could blame him .
