I would try a code scanner and see what pops up. Then call EVO

 

Did you plug-in the ECU without disconnecting the battery ?

 

Try disconnecting the battery, check ecu fitment and install, reconnect battery and test. I got a pasm/psm failure when i disconnected the battery, it cleared up after a couple minutes of driving.

 

You don't have to disconnect the battery to plug or unplug the ECU.

 

Ok I had the same problem...
If this is a spare Ecu (2nd) you have a progblem with the sasi number (Vin). They have programmed something wrong...
Now on the other hand if it is your old Ecu I dont know what it is wrong..
Now with the error codes you have to see what it says.. When this had happened to me it had error codes P2188 P2190 which is system too rich at idle.. From then I havent found yet what is wrong in order to erase these codes..

 

The pasm error happens all the time when you disconect the Battery..

 

Yes I did disconnect the battery.. I plugged the orginal ECU in and the car starts now but PSM Failure is comming up..I'll try and drive to see if it clears up..

Thanks everyone!!

Ofcourse if you drive it a little bit it will be ok.. Everything is ok with your car... You should have both PSM and PASM error... It is ok...

 

Just drove it off and its back to normal so now its Back to Evolution Motorsport!!!

 

PSM/PASM errors are normal after disconnecting the battery... I learned the hard way (thought I messed my car up).

 

Hi,

Reading the forum I have seen that you had p2188 p2190 in your car. Last week I had p2190 after refueling. It was clear and yesterday again I had p2190.

Did you finally discovered what was the problem in your car?

I will appreciate your help.

With respect,

Antonio

 

Was this a new ECU that we modified, or was this ECU running in your car before it was sent in for the upgrade?

 

This sounds like you sent Evo a spare ECU. If that's what you did, the dealer has to reprogram the new ECU with all the cars options. That's probably why it won't start.

Before sending it back to Evo take your car and spare ECU (the one you want programmed) to the dealer and have them code the new ECU. THEN send it to Evo and when you get it back you'll be good to go.

Been there and ALMOST did that.
