Check your ECU before you buy
R8 coils draw high current on the signal circuit, so they only work with certain ECUs. Confirmed working with: any MS3Pro, the latest MSPNP2, FlowForce MS2, SpeedyEFI PnP, and Haltech Elite.
Other Megasquirt ECUs (MS3 Basic, MS3x, early MS2, Microsquirt and others) need an additional circuit. Don't run these

High quality kit! It’s been a few months since I installed it but it was pretty much plug and play from what I recall. This was on a ‘94 so I had no tach signal anymore but the support team responded to my question next day and helped get my tach signal going again. The kit looks amazing, works amazing, and is definitely worth the money. With no other changes to the tune minus dwell times, I could immediately feel the car idle better/smoother. I was blowing out spark in boost at high rpm and this was definitely the right way to go.

Packaged well and everything was in working order after installation. I did convert the harness to sequential firing though. Thank you!

Better to have more coil than I need than to have it fall short.
