Thankfully the best solution is still very practical: convert the car back to a single 1 3/4" SU carb and eliminate the ECU. This opens up the entire universe of performance enhancements and upgrades that have been developed so successfully over the years.
The basic elements of the conversion process are simple enough: Remove the entire FI assembly and ECU, install a conventional 1 3/4" HIF series carb and manifold, replace the ECU with a simple relay, install a fuel pressure regulator and replace the distributor. Wire and plumb all of this together and you have it! Wiring and plumbing diagrams are provided in the kit.

The temperature gauge is no longer used with this conversion kit.
