I purchased a new crank sensor sub harness after my original one was damaged after touching the exhaust. It was somewhat of an ordeal finding the problem, but tech support suggested I check that harness for damage. I was told it was a common, known issue that they were looking at to try and fix. Instead of sending me a replacement for a part they knew was a problem, I had to purchase a replacement. I ended up adding further heat protection in the area of concern on my own and installed the new harness. It is running again, which is good, but I'm a little disappointed that Aces would continue to sell a part with a known problem without upgrading it. An inexpensive silicone heat sleeve would go a long way to eliminating this issue.

Very happy with the value of the Aces system! I couldn't justify spending $2500 on an ecu, and Aces allowed me to get my project running great at a fraction of the cost.
