I recently installed a raptor shift light in my car. It has the LTCC, so the ignition module and coil is deleted. Install was simple, but when i started the car this morning i'm getting a code 42: Ignition module. Since I tapped off of the white wire going to the LTCC (btw its the right one because the shift light works great), I'm assuming the PCM is now seeing an intermitent ground now, therefore throwing the code 42. Should I just delete code 42 in tunercat and load to the PCM and all will be okay? I hate having the SES light on, any opinions.

Thanks,
James

 

I would ask Bob Bailey. He designed the LTCC system. You may have to tap into the wire from the PCM to the stock tach.

 

I cut my signal wire to the shift light and the SES turned off. So I went ahead and just disabled code 42, don't really see a point to it anymore since the igntion module is deleted anyway. SES light gone now
