No real issues on a race E Type but only after experiencing some troubles. You know French, they read the manual after and not prior to installation. Accurate and reliable if you follow the intructions step by step, better on rubber mounts and away from heat.
Only real problem, its not always compatible with after market rev counters like Stack but there's a small device to buy which solves the problem.
If you own/drive any carburetted Ford take care there's a nasty resistor hidden in the original wiring loom feeding the coil positive terminal! You read 12V think its OK then it becomes 9 or 7,5 V just enough to start and vastly enough to get into big troubles. Better replace the wiring and may be have a swithch on the dash board. Dont ask me how I know!
