okay i got a lt8 , wireing is all in, but only problem is not getting any spark from the leading coil, and tahts the only thing holding me back from starting the car
any one have any idea how to get spark?

 

if your not getting spark your wiring is not right

 

well your rite, we went back to a s5 wire harness cuz the s4 harness had problems with the s5 car so, yah we got spark with that, so i think just gonna sell the microtech its just been way to much

 

did you tie in the 12V Ign wire on the leading coil?

 

It is more of an s4 to s5 incompatibility. Your microtech has nothing to do with it. I have a 13B RE and Microtech LTX8 - that thing fired right up. We had to quadruple check all wiring - that is where most problems occur. But, done properly and some advice from 10secrx7, it works pretty well.
