so its coming from aussie. damn hope you like waiting. ok if you get an lt8s take a look at the wiring detail for it. the lt8x which is what i have. can you use aftermarket coils like bosch. but the lt8 has to use the stock coils. this is because on the lt8x the ignitor for the coil is built into the microtech on the lt8 it use the stock coil ignitor. i dont know about the lt8s so make sure to look at the wiring details that comes with it. 1000 shipped is a good deal, the software is free your paying for the cable and adapter. make sure to get a laptop with a serial port. i know some new laptops dont come with them anymore.
