I have a LT8S stock coil wasted spark unit running on my drag car and i am looking 2 upgrade my ignition system,i am still running stock coils and ignitors on my setup and being a LT8S unit i cant get it upgraded 2 run any other coils,my questions is i have 4 msds coils 8207 and a street fire msd ignition box from another project and i was wondering if i can run this coils on the trailing side(keeping the stock igniter)and on the leading 2 more with the msd box,if this is possible can you guys post a step by step write up or a diagram?Thanks.

 

why dont just run a msd 8224 twin post coil for leading with the street box on wasted spark mode and use 2 of the 8207 blaster coils for trailing with stock igniter.

if you want to use two separate coils for leading you will need to msd boxes 1 for each coil.

 

you cant send it back and have it reprogrammed by microtech?

 

They wont do it,they dont support the LT8S series no more

 

I have all four running with out the boxes(tan wire from igniters going 2 POSITIVE on coils,and black wires 2 NEGATIVE on coils)but i think that i can run 1 box on leading just like factory coils,with stock coils igniter setup you run one box on leading so my setup copies the stock one so it should work.

 

thats bull **** man.. im waited for 8 years for the update and now they completly turn there back on the unit..

you can look into the dynatek there pumping out the most mj out of all the systems if your interested. the dynatek arc-2 is hitting for a wopping 189mj and its the same size as the lt8s, im going to setup with the stock coils and pre water injection.. maby something to look into
