i never thaught about the batteries being a problem having put two batteries in my rocket one of the batteries was two years old.
finally i bought two new bats. through a little charge on them (latter regret not checking them) and put them in my 07 and only hook up one would not start with out bat charger so hook up the other bat in parallel then it started up with out a problem.
of coarse i am in arizona wont know till winter if the cold start problem is fixed.

Mine was taken off every month if not used much and put on a optimiser for a few days to charge and bring it back to good condition again , made no difference if fully charged, iv a voltage gauge on there and shows its 13.5 volts on average charging back to battery.

if it is charging at 13.5 while running that is great
however it is when it is cranking that makes the difference.
mine actually started at 9.33 then sometimes would not start at 10.5.
seems to make a difference on how fast it cranked whether it would start r not.
yours may not be the same problem as mine but it sure looks that way.
the ecu would not trigger the 2second coil now i did not test the other 2 because it did not try to start.
now if i put my shop charger on hi crank assist for 30 minutes it would start and run good all day and would not turn over the next day
i would reccomend a new good battery i think it is a better way to go than the things that i changed.
the ecu firing coils is easy to check with the old dwell testers i could actually tell when it was going to start. also you can check with a 12 volt test light if it has the correct ohms.

?????? Don't know the answer to that one ,but surly wouldn't be to difficult to put another relay into the system .What do you guys think ?

I agree ,thought they changed to the extra relay when they introduced the Roadster. ???

i think you are corect and they made a relay as an add on.
so i think that this ecu will work as good as your old one (just had to put that in there)
