I have a 2006 350z I just recently put a momentum turbo kit with a haltech platinum plugin play ecu and we can get the car to crank and run fine but after about 15-30 sec the number 3 and 6 coils and EXTREMELY HOT to the touch but it's only those 2 we have replaced the coils and it still does it I've read it could be a ground issue looked at every ground cleaned them put them back on, put new spark plugs in, bought a grounding kit, turned the dewel time down to 1ms done everything I could think of still burning coils so if anyone has an idea or ran into this problem please let me know trying to get it running for my buddy before he gets deployed thanks!

 

edit: max dwell time is 4.4 ms. It has to be either the ground wire for the coils or ECU (ground triggered I believe, so the ECU is supplying the ground) or there is oil in the spark plug tubes from a leaking valve cover gasket. Make sure the ECU is properly grounded. If you are running the stock ECU with the red haltech, make sure the stock ECU is properly grounded and not lying on the carpet.

 

Do you have the proper impedance set for your injectors within the Haltech?

 

The haltech is mounted in the stock ecu place and we pulled the spark plugs and put brand new plugs and coils in there and we have set the dewel time from 4.4 all the was down to 1 and still nothing and yes the injectors are.
