I have recently purchased the LTCC from Bob Bailey. I bought used coils off ebay, had sun spec fab some valve cover brackets for coils, and brand new taylors. Well after in stall, car started and sounded perfect. I had no red lights on the LTCC BOX. Well after a week of driving, I am getting 3 red blinking lights. What is the cause of this? How can i test whats wrong? How can I test these ls1 coils? Car pulls hard when WOT but does miss/backfire occasionally, most problem is at idle. It surges from 500rpm to 1krpm and will eventually die if I have my A/C on. Please Help guys, as I have emailed Bob several times last week and no response yet. Thanks James....

 

3 blinking lights means its not getting the correct counts from the opti. Is the opti good? Might just double check the opti connections and opti harness tee in harness to the LTCC.

 

Opti was good before LTCC. Car still pulls to 6600rpms....when my opti was crapping out it was a dogg under 2500rpms and would really miss after 5500rpms.

 

I don't know of any good way of testing. It could be a little piece of trash or something covering one of the slots in the opti wheel but, it would be a pain in the butt taking it off. Mine has worked for 3 years with no problems.

 

It was a dead opti!
