JDS Porsche

We at JDS Porsche are Electronics Specialists who have developed a range of reliable products and services for Porsche vehicles. We first established here at our base in Cambridge in 2002 after finding that the 928 Porsche they owned since 1999 had a bad reliability reputation for LH ECU failure, MAF problems and general electrical issues. These problems lead us to investigate the reasons behind these MAF failures, and in the end, we decided to form ‘JDS Porsche’ and offer better rebuilt units to other owners. Founder John Speake had a background in electronics, so had a wealth of knowledge and experience to aid his goal to create products that would be more reliable.

The Products & Services we provide includes:

  • NEW SharkTuner Mark 1
  • SharkTuner Mark 2
  • SharkTuner with “Flash Tuning” modules (PEM)
  • The SharkTuner Alpha-N system
  • SharkPlotter program
  • MAF Diagnostics & Repair
  • LH and EZK ECU Repair
  • KTS300 Hammer 9288
  • 928 Cam-belt Tension Tool
  • Porsche ‘No Start’ Problem Advice
  • And More…

We developed a repair strategy for the notoriously unreliable LH ECU used in the MY 87 and later 32 valve 928’s, and some of our more recent products have been diagnostic testers and tools for the Porsche 928 and other Porsche models, and the SharkTuner. The SharkTuner is one we are most proud of. It offers a full remapping and engine monitoring system, with data logging for all the LH equipped cars – from MY 84 for the Euro 16v and MY85 for the 32v S3 and S4 (MY87 onwards). To complement the SharkTuner, we also have the Sharkplotter program, which provides powerful post processing and viewing options. Another one of our latest additions to the SharkTuner range is the MAF-less Alpha-N system.
