remove the 4 bolts holding it in. turn it over, and with a sharp knife cut the rubber seal all the way round. then very carefully prise the base plate off the ECU.

Thats it, remeber to re-seal it with sillicone once you've finished.

I could save you some hassle though, its very unlikely a 99 Sei will have a removeable EEPROM.

Do you mean IN-correct? As Arc said that it would probably NOT be removable :confused:

No I mean Arc's instructions for opening up the box were correct but his view that the chip would be soldered is not.

Sorry - my bad. Go with what Michael says, he knows a tintsy bit more about ECU's than I do!

I just assumed they'd be soldered because the late Cinq ones were and Sei uses the same type of ECU.

Wasnt Gaz's soldered though?

I have looked at 3 '99 ECU's all were socketed. Not looked in the one I got from you gaz, but will let everyone know what I find when I do.

If you're after a chip i can supply for a '99 Sei sporting @ £50. Just need to know what is printed on the Label on the original chip. [usual moneyback guarantee applies]

I hope you don't mind me asking but where have you fitted the ecotec, there was a thread on here a few months ago that seemed to say that there was no suitable place to fit one on a cinq or Sei. How do you rate the ecotec?
