when and/or why do you need a pectel board inside a L8/P8 computer...

is this because the standard computer cant drive waterinjection, als, airinjectors etc etc...

someone could explain...please

foreigneRS

i would be interested to know as well please

my understanding is that you don't ever NEED one for any of those features that you mentioned, it's just that it allows someone who has the pectel software to be able to make any changes.

Ive written mini essays on this and simply cant find them
Give me 20...

Ok, here goes...

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.

Ingenious.

The are a few different types of software that do water injection.

Air injectors need a hardware add on that we charge Ł100 for. This hardware IS INCLUDED in a Pectel board.

Only the P8 can do ALS due to hardware limitations.

All teh above modes of operation are simply software mods to the ecu, nothing more. Pectel made it all childs play for their dealers, for teh rest of us lifes a bit harder. lol

So if you have an L8 ECU you can't run ALS???

I've seen saffs with ALS, so they must have another ECU or management??


Cheers for answers

foreigneRS

good read, thanks stu

GARETH T

will normally have a p8 inside them

Mechanic_Wedgie

Is that an complete ECU or just a extra babyboard or something like that??

For those curious, here is a pic of one:

This one is for an Es Cos - Stage 3 greens:

nice 1 stu top read

GARETH T

ahh i didnt know where it all came about,,, nice one stu

s1 2oobhp

does a pectel board solder in or plug in

GARETH T

plugs in mate

s1 2oobhp

cool

foreigneRS

so not only does the eeprom contain the maps, but it also contains the run program?

that is how you can add functionality like closed loop lambda in the eeprom?

so on a p8, what is the hardware that they have that allows them to run anti-lag that l8 doesn't have? as i understand it, you would use the same pwm circuitry to open the (modified) iscv, and just change to different maps for the ignition or fuel?

Stu @ M Developments

iTrader: (12)

Yes. Ist all there, including error mask and fault code operation.

The hard and software is capable of retarding PAST TDC, none of the other ecus are.

foreigneRS

Stu @ M Developments very interesting mate

thanks for continuing to teach me something

that's what makes the site "a reference site for ford enthusiasts"

Dave Henshall

just out of interest,there is also a later type of pectel board for the P8's, it only has 2 chips as opposed to 3.... the second chip is a much thinner squarer chip

Fiecos Dan

So, can any pectel board fitted to l8, can it run

coilpack, water inj, air inj, closed loop lambda?


Also i have a Super 8 p8, can that run the above and Anti lag?


Do they just need a new map/chip.

Do all L8 ecu's have a board?

i've seen 2 which have no board

Stu @ M Developments

iTrader: (12)

Yes. Its a L6 without it.

Mark_1

issue nr 2 pectel board if anyone is curious.

Does anyone know the differences between issue 1 and 2 (and 3?) boards?

Dave Henshall

the issue 2 boards suffer on SOME ecus on SOME cars with an initialisation problem where the fuel pump doesnt prime, unless you switch the ignition off/on again

do you need to have a pectel board to manage air injectors ???

Stu @ M Developments

iTrader: (12)

Not with our software, no.
However, if you have some software that cannot do it, we can sell you a driver to make them work correctly, but they will of course still need mapping in.

so, i need a live map to use it ????

Stu @ M Developments

No, we can do it off teh shelf, but the boost is normally done live for best results, yes.
