[Supras] Strange AEM EMS activity

[Brandon]

Any of you AEM guys mounted the  box to a metal part of the car similar to 
the factory ECU?   I am working on an 88 for a customer, and w/ the  EMS 
mounted http://www.transonicracinginnovations.com/gallery/album28/93_G

w/ the key on car off the fuel pump will cycle on for about 2 sec, then turn 
off, and then repeat.  of course the car will not start w/ this going on. 
If the box is ungrounded (unmounted), then everything seems to work well, 
car fires up and seems to be happy.

I don't know what everyone else did w/ their EMS, if they left the lay in 
the glove box or what, but i imagine that someone mounted it to keep it 
secured.   Ideal for me would be to find someone else locally that has an 
87-88 GTE supra so i could test the box in their car and see if there is 
sometihng strange wiring wise that i may have done to cause this.   (the car 
is running sequential injection, w/ MAP, and the AEM is controlling the 
boost as well, or will be).  Oh and yes i've talked to AEM on it, and they 
weren't really sure lol.

thanks
