depends what you fiddle with?

if you recode the clocks to your new ECU, it won't work until you recode it back

It sounds like the engine ECU might not be connected to the CAN-bus loom; even if the ECU needed to be coded to the clocks, it's still allow it to be interrogated by the OBDII

I know of vagtacho, but I've never used it

I did have an SKC reader, but I never tried it for fear of cocking up the ECU

i will soon try to swap an ecu on a mk3 ibiza cupra (it's immo 2 if i'm right), do i need a skc code to do it ?

the procedure for immo 2 seems really simple, i thought you had to read some values from old ecu and write it to new one.

also will there be a problem with the radio (need radio code) ?

thanks for helping me to be sure i will do it correctly :lol:

Jay,

You don't need SKC - it's Immo2 & it's so easy you can do it in your sleep.

No radio code on the Mk3 HU

i might b swapping a 225 LCR ecu with a 225 LCR ECU with revo stage 1, is this just the imobi code and then everything works perfectly or is there anything else....

Hello guys,
I have a 2009 Leon Cupra with an APR fully loaded ECU, I'm planing to change my car for a brand new 2011. Can I swap the ECU between both cars using this procedure?
The reason I ask this is because the new Cupra only accepts one APR program...it seems like the new ECU has a smaller EPROM....
thanks!!!

How's that supposed to work? :)

Your 2009 had a completely different engine that the 2011, also the ECU is a completely new generation with different pin outs etc. The problem here is not that the ECU has a smaller memory (the opposite is true), but APR hasn't figured a way to do switchable programs on the MED17 yet. ;)
