Faulty Stillen Throttle Body extension cable?

Sinister_z34 · 04-11-2019, 08:36 PM

Happened again to me today on the freeway and this was on the new revised one that I installed within the last year or so. Fortunately I had my obd2 with me I was stuck in the fast lane till I cleared the code (p1239)

Let me tell you the story of my people:

I have a 2007 HR 350z now at about 60K mileage. Three years ago (Summer 2016), I had a local shop install the a Stillen/Vortech supercharger. I have some non-HP supporting mods in the engine, hi-flow cats, and a motordyne exhaust. I wanted a conservative tune since this my daily driver and only car, I have about 400 rwhp and 315 tq. Performance wise I'm very happy with it, and I don't abuse the car. Fun highway driving only.

However, I have had multiple problems with the kit.

Problem 1: Bad Throttle cables
A few months after I bought it, Stillen came out with upgraded Throttle Body Extension cables but deigned not to mass inform their customers. These cables were improved to have a much thicker gauge since the original ones were crimping. Crimping may, and in my case did, cause the engine to not turn on, or go into 'limp mode'. We had to buy the new upgraded cables for $140 and install them. Still, this required a tow and a few days down time. All sets bought post winter 2016 will have these new cables

Problem 2: Heat/EMI problems
Maybe about 6-12 months after that, it happened again. Was driving just fine, the next morning for work, car turns on, then heavily lurches, dashboard is now a xmas tree. I get it towed to same shop, the check engine light is a P1239 code. This is a very famous code for this error, its all over google and Z forums. After conducting forum research, the 'new' cables Stillen provided still are susceptible to heat and electrical interference, so a heat/EMI sleeve was placed over the cables.

Problem 3: Now ******* what?
This morning (May 14 2019), the car went into limp mode again. Jesus ****ing christ what now? After several attempted restarts all fail, I call a tow. An hour later, the second the tow gets here, I start up car just fine and it seems perfect, like nothing is wrong albeit with check engine light. It's in the shop now, they are looking at it.

So overall, I'm kinda not that happy with Stillen. The performance is great, but this is my only car, so I care more about reliability. Something is seriously wrong with their electrical division, but its the same problem now 3 ****ing times over the past few years.

Does anyone know if the 370Z Maf cables are compatible with the HR? If so, I have a pile of Gen 2's sitting in a box.

If anyone needs one I will sell them for $20 a pop.

Excuse my limited knowledge, but are MAF cables the same thing as Throttle Body Extension cables?

wideglideleon · 05-14-2019, 02:25 PM

I have had the same issue three times my self with my 370. Always the damn extension cables.

Rev_Night · 05-14-2019, 02:33 PM

What did you do to fix it? Is it still occurring?

wideglideleon · 05-14-2019, 02:56 PM

Just replaced it again. Three times in two year so far.

TopgunZ · 05-14-2019, 03:02 PM

Unfortunately I dont have the Throttle body extenders, only the MAF extenders.

sounds shitty. Do you do the work yourself?

Do the MAF extenders have anything to do with the throttle body extenders? Or are they different systems?

wideglideleon · 05-14-2019, 05:40 PM

Of course I replace them myself, you unclip them and plug new ones in. I have tried insulating them, that lasted the longest. I just replaced it again,its always the same one for me that fails. It's always the throttle body extension cable for the drivers side on my car.

Rev_Night · 05-14-2019, 05:52 PM

dumb question, the cable in question is just the one below right? Nothing more?

Where are you getting the throttle body extension cables and connections? I'm in the middle of tuning with seb and i completely lose all throttle response. Seb Said "issue with the harness adapters from Stillen for the throttle." I need to replace these to continue tuning..

Is there a link where I can buy these on the cheap? These extensions cables?
