that ECU i bought at ebay for alot Pounds... today it received me... and my car always have Engine Fault....

the seller told me that overthere is a Performance Chip installed...

what offers that all:

If the fitting is a 4 pin plug it should fit boost power to around 280-290BhpThis chip will: Raise your boost level to 16psi
> Remove the 112mph speed limiter on Japanese imports
> Allow you to run normal superunleaded safely (no need for octane booster)
> Improve turbo spool up times
> Retain all of the ECU's standard safety features
> NOT make the 'check engine' light stay on all the time
> Give you better fuel economy

and what my eyes seen after i opened the ECU


a crap platine... what was soldered in with 4 cables (+ / -) and 2 other ones... what i cant see where its soldered exactly in... but i am sure that this is a Crapy MAF Hack... ARG

or what you think

Bulldogge

it was soldered in on B43 Pin 4 on the ECU... hmm whats that... but i also see that they tried it on 5 other positions also.... arg

ups sorry i forgot .... pin 4 i checked is the pressure sensor... maybe cause that i have with this ecu the fault code 44 (wastegate solenoid)

thats a pic of the ecu

Dunno what that is.. but it wouldn't go anywhere near my car

A 'Performance chip' should be locted in the IC socket (under the small board). Thats where mine lives, see my scooby!

i know... this is some "Art" of Hacks what i really hate....

i think they had use it to trick out the max. boost...

Could be to kill fuel cut

Thats a Superchip or sometimes called a Superchip ABC board.
Connections are :
Red : 12V
Black : Ground
Yellow : Map Sensor
Green : Map Sensor

It's basically a boost clamp/fuel cut defender, that works in conjunction with a bleed valve (under the bonnet).
i.e Bleed air away from actuator = More Boost
Superchip Board = Removal of Safety Fuel Cut.

It certainly doesn't :

Remove the 112mph speed limiter on Japanese imports
Allow you to run normal superunleaded safely (no need for octane booster)
Improve turbo spool up times
Retain all of the ECU's standard safety features
Give you better fuel economy

And in your case is doesn't even manage :
NOT make the 'check engine' light stay on all the time

Believe it or not the boards and the bleed valve retail at approx £400

Here's one I ripped out of an ECU that was being upgraded a few weeks back :


If you remove the board you need to rejoin the connector pin where the yellow and green wires attach. When this board was fitted they would of physically cut the pin off the back of the connector.
This is best done by cutting the Green/Yellow with about 30mm spare, then join green to yellow, thus reconnecting the connector pin.

If you have just cut the board out then this will give you an error code, probably Code 45.

Bulldogge

is it correct than this is normally on pin 4 ? thats the pressure sensor!

Pressure Sensor = MAP Sensor right?

I still have with this ECU Fault 44 it makes me really sillly

Scott.T@PolarPerformance

Yes Pressure Sensor is MAP (Manifold Absolute Pressure) Sensor.
Code 44 is the boost solenoid.
If you connect the green adn black connectors under the dash you shoull here the solenoid working.
