Is there any potential for ECU damage in 3 ports without resistors?

There seems to be a lot more people running mac valves and gm solenoids without resistors these days has anyone ever damaged a stock ecu or is it even possible to damage the stock ecu by using a 3 port that isn't matched to the stock BCS in terms of current draw.

I know it's probably been covered a thousand times before but as Ive only got my iPhone at the minute with no laptop access searching is taking forever, just how far out are these type of 3 ports compared to the stock BCS in terms of resistance?

heres a link to the evoecu wiki page. Some of the popular 3 port resistances are listed.

Cheers for the link it seems that the GM is quite close in terms of resistance has anyone tested a grimmspeed as this is meant to be designed to work with the stock ecu I'd be interested to see the resistance.

You do not want to wire it without any resistor because youŽll take the risk to burnout the output transistor in our ECU.
For a GM, resistor has to be 5.8 ohms - 3Watts.

Just out of curiosity if you could damage the ecu by using a 3 port without a resistor what exactly would happen to the ecu would you lose boost control altogether or would it still work but incorrectly.
