Limp Stillen Supercharger dtc p1239

Are you still using the stillen cables? Even with the heat shield, only 1 of the cables is insulated. Meanwhile, the OEM cables, 4 out of the 6 are. Trying switching to those

Edit: For the p0300 code, funny enough I did get one of those in the extreme (Polar Vortex) cold. My car started and drove fine btw, just that check engine light on. The shop said it was because they gapped the spark plugs closer than they could have to protect against premature ignition which can ruin the engine. They said the code would go away 1) In warmer weather or 2) After a few minutes of highway driving.

They were correct on both accounts. I've only see it just that once.

Edit 2: For what its worth, i have stock GTR spark plugs in my 350z (HR)

I'm aware of 3 stillen cables. One to extend the TB harness, and the 2 MAFs. Which ones are you saying to switch?

I'm using OE 370z spark plugs on standard gap... They are +1 colder for my HR. I have not had any issues with them when driving hard. Just idle with the p0300 and this p1239.

I have a turbo smart bypass I'll install and try to screw around with... Heard it's tough to get it right


Thanks for the info.

If possible, replace all of them with OEM. I'm not sure about the MAF, but most def replace the TB harness.

As for spark plugs, they installed oem GTR in my 350z (HR)

How do I get an OEM extension harness?

**edit**
Are you talking about getting OEM wire and just cutting the OEM harness and extending it?

Rev_Night

You are asking questions that I can't answer, since my shop did the work and not me. Perhaps look in the Technical Service Manual in the Electrical section? Look for all SKUs that are wires that go over the entirety of the top of the engine.

Also, I will take a picture tomorrow of my engine bay and show you.

Awesome! Thanks. Pretty sure this will help ALOT of frustrating SC'ed Z's on this forum. I F****** hate this Stillen kit with absolute passion. Close to taking a $h1t in it and sending it to stillen's front door ;-)
