Bosch Motronic Questions

[Brad Anesi]

Two questions for the collective...

1) I've been told that it is possible to lessen the spring force on the door
of the Air Meter by moving the spring back a few notches, which may
somewhat lessen the throttle lag issue.  I've tried to get to the spring by
removing the bottom plate of the meter, but apparently access to the
spring is from the top.  My question....  How do you get the black plastic
top off without destroying it in the process?  I'd also be interested in
hearing from anybody who has experience with this modification.

2) What blank E/PROM chip do I need to order for the ECU?  (I've got
access to a chip programmer and wanted to make back-up copies of my
current chips).  Also, any suggestions on sources?

Thanks,
