installing EAT chip/could somone pls explain how get top board.....

[ryan roopnarine]

off in the ecu? i've tried to simultaneously disengage all 4 of the clips, and the top board is wiggling, but its not moving backward.....i was trying to save swapping it out until i could take it to the track and doing a before and after with time slips, but the track is apparently going to be closed until march....

4 clips? There are 2 clips that you have to move inwards, (look in the housing where the wiring harness connects) And then you move the top board at a 30 to 45 degree angle, and slightly twist it from side to side will pulling it also.

Did you look at the instructions on Bruno's site?

Here are some other instructions that may help:

(installing an EAT chip in an M5, but it's the same dual board system you have)

the two yellow post things by the wire harness. i take it i have to wiggle it pretty hard? thought the clip things in the outer connector were integral to extracting. i looked at bruno's site already though, and logun's e36 page, but that one has a single board.

pop it up off the yellow clips including the center one, lift the back of the board about an inch, then pop in a small screwdriver or paper clip to disengage the side clips (where it plugs into the harness) and pry it back...was a biatch first 2 times I did it but its really easy now.
