Hello,
It is not a good idea to open the ECU for the motor at all. Ideally it should be done in dust free, static free conditions and resealed with silicon when closing it back up again.
You need to pry the cover off very carefully so as not to damage it so much that it can't be re-installed.
I opened up mine as a last resort when I had starting problems and found that oil had leaked from/through the loom into the ECU. I cleaned it out with electrical contact cleaner and re-sealed it(there was a good 2 tablespoons of oil that had entered the ECU).
It all works well now as the wires(after the injector loom, shortly after where the plug connects to the head on the exterior of the head) are spliced, soldered and heat shrinked so that it forms an impenetrable barrier that the oil can't pass through the rest of the engine loom. It works too......No further issues !
Cheers,
Jason
ok thanks for the advice :)
No worries, i'm opening mine without even unplugging it(just battery disconnected) at least 4 times a year to swap the stage 1 chip with the stage 2 according to my needs and i'm not using any sealant just treating the PCB with naoprotech electric once a year... i've been doing that for about 3 years without any problem.... and i can't see why would that be risky or why seal it with silicone as long as it wasnt sealed like that from factory, it has a rubber seal which is enough IMO, it's not some neurosurgical chip to be infected
Agree 100%.Quote:

If you use a hot air gun or hair drier to heat around the edge of the upper lid to soften the seal, then use a wide thin paint scrapper to gently lever the lid off it's pretty painless. With a bit of care you can get the lid off with no damage. I don't bother resealing now.
