        It would take alot of "E,M,P," to damage your cars computer,
Most onboard computers are shielded going to the cars chassie,also alot of 
todays chips are case hardened.I've had some small problems,i owned a toyota 
Mr2 sportscar a few years ago,the CPU is in the trunk my ham 
transmitter(kenwood ts-440s)was on the floor, if i took the automatic antenna 
tuner off line and maually detuned getting lots of rf flowing over the 
antenna shield (around 100 watts)the car would start to stall out on me.At 
that point i would key up and everything would come back fine,this also 
happened with my Swan 500(500 watts).The other thing is all my cars are about 
40' from my 18,000 watt T.C. Tuned to 105khz never had any problems.So i 
would have to say your alright unless you give it a direct "hit"
