What is this??

Hi all,

Stripping down my dash to install an alarm and tidy up loose wiring, i find this...
Anyone know what it is?

speed cut defender? where does it wire into the loom of the car, specifically what wires on the ecu, trace them back and see on your wiring diagram what they are, should give you a decent indication of what it does ;-)

What is the number on the chip? that might give you some clues

Also the first two pictures don't work. EDIT: now they do. go figure...

I cant tell where its wired in, its very tight in there and i dont want to dig too much.
What i can see though is that its wires go straight into the ECU plug... there are no wire joins, etc. Strange.

The 8pin IC in the box has had its label sanded off

it's almost certainly a something-cut defender work out which pins it goes into on the ECU and that will tell you (speed sensor, MAP sensor, crank angle sensor, etc)

TOMS.... Toyota Oblong Mounting System.... This Object Modulates Speed.....Throw Out.. Mistakenly Soldered.......This Object Must Stay

Sorry rainy day, and nothing better to do Truly Orribly Massivly Sorry I'll go now... I promise

what car is it that you're working on? and yeah, what pins does it go to?
I have a few ECU pinout diagrams lying around...

[MWP]

Its a FCD.... i traced the wires.
Well, i assume its a FCD as it intercepts the MAP sensor signal.

Funny, if it is an FCD, when i bought it the car had two.
This one, and one that was installed in the engine bay
Some people have no idea

[NORBY]

you had a good defence then eh

[MWP]

Heh, not any more

Both have been removed.
Im not going to be going near the 14psi cut, so they are not needed.

Not that it could go near 14psi anyway, the wastegate actuator on the CT9 is weak... it starts opening at 10psi.
