Do  you know the weight of the GM coils.  If there is a

significant

difference,  I will change if Tracy can be talked into making

the

requisite modification to  the controller.    Jerry

My six coils, with the mount weigh 4.5 lbs (pic attached).  I'll

guess

the
mount wieghs about the same as a 12 oz bottle of beer - maybe a

couple

less - so the coils are about 10 oz each.

BTW; I still have a couple of these mounts if anyone is

interested.

How much do you want for one of the mounts?

Do you need to modify Tracy's controller or will it drive the coils
directly?

Any EC2 can be changed over to the GM coils (AC Delco PN D580) by changing
the controller chips, which are in sockets.  If your EC2 was equipped with
the earlier 3 wire air temp sensor you will also need the newer two wire
type.  There is also a proceedure to initialiaze some new parameters stored
on board in EEPROM as well as a new installation guide. Contact me directly
for details.  I haven't figured out pricing for a 'do it yourself' update
kit for this but it will be less than $50.00.
