Hi can anyone help I'm looking for a garage to check out a misfire I have on my 1997 300zx twin turbo it has had a lot of modifications made to it including piggy back ECU so I need a garage who will look for the problem and not just say the system needs to be put back to standard I have owned the car for 4 months and its been running great then last week it started to misfire I have changed the spark plugs and checked the coil packs which are OK but misfire still there

Please contact me with any info either about local garages or suggestions on things to try to solve misfire

Thanks

Malcolm

Hi, welcome to the club :)

 

Your best bet is to pop across the bridge into Bristol and visit Jimmer @ PowerZed. One of the best in the country with these engines and relatively close to you.

Yup, Jimmer @ PowerZed is not far from you at all and the place to go.

 

Does it have an Emanage or Unichip fitted?

Thanks for the replies guys does anyone have a phone number for Jimmer at PowerZed

Noz I take it that your asking about the piggyback ECU if so i really don't know what's fitted or how it works or what the advantage of having one is

There is no advantage to a piggyback ECU on the 300zx, the standard ECU is fully mappable. It was probably fitted due to your '97 Zed having a 16bit ECU and the prior owner/tuner not knowing how to map it.
