Hi,
I own a s13 w/ rb25det s1 swap.
Bought new coils replacement for oem.

Everytime i turn the car on and accelerate it a bit, coil #1 seems to burn...
Ive had this problem with 2 coils already which melted. This only happens to #1

Any suggestions?
Car is running a z32 chipped ecu...

Some say maybe a ground issue...or too much voltage?

Any help or comment would be appreciated, thx

Id just check your constant voltage at the Coil. If its high find out why. Also just check the ground continuity.

great advice. exactly what i would do.

check the quality of the coil which you are using, use as per the mentioned standard also do check the voltages properly.
