Can anyone help me. I decided to send the ECU of my Volvo to Inmotion Tunning so they can modify it. How do you remove the ECU, what precautions should I have when doing so, and at the same time, is there any risks when removing it and installing it

 

Let the car sit with the Key being off for over 5 minutes.
Then remove the black top cover. The ECM is teh one with Bosch on it.
The TCM has AW on it.

Slide the arm over the top of the computer and slide it out.

All will be fine as long as you don't turn the key on with it out.

 

I usually wait about 15 minutes after disconnecting the negative battery cable before removing the ECUs. I distantly remembered that somewhere I read that the ECUs are still powered even after the battery has been disconnected. However, this may not be true.

After removal, make sure not to touch any of the pins with your finger, as some electrostatic sensitive devices may be damaged. Wearing a wrist-band type static discharger would be perfect, but I haven't found one in the States. I'm sure they are available somewhere, but not at Radio Shack.

Holding your foot on the brake pedal for about 30 seconds will ensure any residual stored voltage(s) is eliminated by allowing the stored voltage(s) to dissipate through the resistive circuit of the brake globe filament.

 

+1, just make sure you discharge any static electricity by touching the battery´s negative connector with your bare hand right before proceeding with ECU removal. In practical terms that would be equivalent to using a wrist band static discharger.

Also make sure you protect the ECU using anti-static bags during transportation.-

 

This is correct.
Disconnect the battery, and wait 5 minutes if your paranoid.

For anti static staps try a company called RS or Farnells.
Both are expensive but have (normally) top notch bits.

Or you could just run wire (with a 10ohm resistor) from the cars metal work to yourself.

Static damage to car ecu's is very rare. (used to repair them - never saw one with static damage)

 

Thanks for all the info, but there is something that worries me, if the chip modification is done to the ECU, wont the engine and the turbo have to sustain more stress, since they ar both working harder to deliver that extra power ?. In resume, is it worth it to get the ECU modified ?.

 

It will work harder but might also give you a little better gas milage as well.
It all depend on your driving.

 

And how well you keep up with scheduled maintenance.
