Limp Stillen Supercharger dtc p1239

wymoteeZ · 04-10-2016, 12:05 PM

Radioflyer,
I was just reading again the link you referenced Early On to me about p1239 & about the foil shielding on the TB extension cable. JWillis72 has been working with me help eliminate the MAF & filter-shield areas. I had not had a chance yet to say Thanks to You yet. Thanks. Now I see your post reinforcing the idea to shield. That is my next try today. Thank you for mentioning that it also needs to ground, awesome! Did you read my joke about power lines ?? In my p1239 Journey, I have actually had two exact places where it has gone limp. I will be better scouting both of those areas today. (simply because We want to Know)

I was out of ideas when I had the same problem. As a last attempt at *anything*, I looked up wire shielding in case there was any interference getting in the way of the TPS extension cable supplied by Stillen. That's the one that crosses over the front of the motor. I ended up wrapping my cable extension cable from connector to connector with aluminum foil, and letting it ground itself on the block. I used electrical tape to secure it, and made sure there were not any exposed wires. Well, coincidence or not, I haven't had the problem since. It's worth a try, won't cost you anything.

Had this exact same problem, too the T.

Theres a problem with the extended throttle body cable.

Before stillen had the replacement cable throttle body harness, you had to solder them together, I found a huge change in resistance when the wire was moved.

That would definitely cause this kind of problem.

Did you fix the cable or did Stillen replace it?

I work in the aerospace industry as a EE and this kind of stuff happens all of the time unless proper procedures are used for making cables. Our standards are very high but sh*t still happens.........

I've got a couple days, & about 100 miles, on this foil-fix.
It also fixed some power-surging I was getting at full throttle.
Originally, the TB Extension Cable was routed across the engine -> hidden down under.
During the p1239 codes, I had already plugged, & unplugged this cable for connection problems. I never re-routed it.
So, it was either moving it up above the engine, or foil-wrapping, & grounding the wrap that has helped it.
A third possibility is that Z's just respond well to Bling !! They also respond well to a 40 lb. Bag of dog food in the back.

I called Stillen yesterday to price 2 TB gaskets & a new TB ext. cable.
They requested my trouble code & a picture of the cable I needed.
Maybe I will hear from them today about the 'price'.

You might want to consider resetting the ECM if it's a box tune. Mine is still running great.

Have you checked the pump and coolant level for the Stillen intake heat exchanger?

RadioFlyer · 04-12-2016, 05:15 PM

^ That looks pretty similar to mine, only mine is under more of the crossover stuff. I put mine under so the foil grounds itself by laying on the engine block. Either way, believe it or not, I think the foil actually helps this issue.

No problems on today's Drive either. I totally thumbs-up this fix.
I wrapped copper-strands into and around the foil at about mid-point & bolt-grounded it to the block. (nothing is crushing anything). I still have my MAF connections under the hood switched, & untidy too. I will tuck things away before it's all over with. haha I know, isn't that gawdy?

I followed up with Stillen today about my parts.
I guess I didn't convince them that my Cable was faulty. The TB cable was $30. I bought the kit 11-5-15.
The TB gaskets I wanted for Spares were $4 each. Not too bad a price on either item.

wymoteeZ · 04-27-2016, 08:05 PM

I have had the new TB extension cable on for a week or two. I routed it above direct engine-block heat. It is not foil-wrapped.
I did want to offer a small factoid about the extension cable. I don't think it was my specific problem, but I feel it is good info. to pass on.
When connecting any of the TB connectors, there are TWO distinct clicks. The connector is 90% on when the 1st click occurs. Then to fully connect it, & hear the 2nd click, it pushes in about 10% more. I had three different companies with SC Kit experience tell me the same thing. --> That some people stop after the 1st click, & it can throw the p1239 code. It was Stillen, UpRev, & JoTech.

If you use Christmas wrapping maybe you'll get 550hp........

Use something like this....

https://www.zippertubing.com/EMI-Shi...Shield-AL.html

To offer EMI protection for cables. Tinfoil is not a permanent solution, when you crumple it up and wrap it you cause small tears in it, plus the car vibrations degrade it too,

Not to mention that electro magnetic interference (EMI) shielding is useless without a proper ground (drain). Wrapping foil around wires can only be effective if the foil is well grounded.

Following. Just ran into the same code and limp mode after an ecutek tune, so I tried the foil for now and rerouted the wires. Will see if it resolves the issue.
