Public Service Announcement for Caterham Owners:
Attention owners of Caterham USA supplied Zetec engines equipped with Pectel T2 engine management systems.
MSI Motorsport has recently been re-mapping several Zetec equipped Caterhams. On more than one of these, we have found that they have been factory equipped with low impedance injectors.
Low impedance injectors will eventually burn out the Pectel T2 ECU, generally sooner rather than later.
If you have a Caterham USA derived Pectel T2 based system, you should immediately identify the injectors in your car. If you cannot do this with part numbers, suitability (electrical, not necessarily flow rate/mapping) can be determined by checking the resistance between the two small harness contacts in the injector. Correct impedance should be in the 16 Ohm range, whereas the incorrect low impedance units will show something in the 2 to 3 Ohm range.
We now return you to your regularly scheduled program.
Cheers,
Woody Harris
