My good friend had a supercharger installed on his Sky this winter. The car has not run properly since this conversion. It is running very rich and almost feels like following a diesel when I follow him. Can drive gentle in the car but any agressive driving will send a code P300 and if continued will go to transmission protect P100. Some GM neighbor folks have put this on computer and found that all cylinders are missing and sending the code.
Supercharger installer said they would repair in Canton but spent minimal time with no results. Reprogramed and changed plugs in Canton with no correction. Since Canton the coils, fuel injectors and Mass Air Sensor were changed with no change. A promise was given that installer would come to friends home over the 4th and stay until corrected. 4th has come and gone with no contact, so therefore no correction.
We are not savy enough to do anything further so can anyone suggest a local garage or someplace the car could be taken to correct? I doubt that any GM dealership will have anything to do with this since it is an aftermarket install. Or any conversation or ideas would be great to hear. This car owner is getting very frustrated after spending so much for this mod and car actually runs worse!!

Is this SC DDM installed?

WickedMike · « **Reply #2 on:** July 06, 2010, 10:42:41 PM »

Yes, a 2.4 automatic

Read on the BB that it's a DDM supercharger, but he's got a tune from another company... That could certainly be the problem...

WickedMike, are you getting boost? Check the bypass valve to make sure it is operating smoothly or at all. It is normaly open when running & not under load, if it does not close then you do not get enough air flow (boost) for the extra fuel being sent to the engine during heavier throttle conditions. Make sure the vacuum line to it is connected & has no leaks. You can operate it by hand WITH THE ENGINE OFF. It's just a butterfly valve you can push open with your fingers & when you release it the spring pressure should close it.

If this is in fact true, it most definately could be the issue. Don't know where you are located but a trip to DDM's facility might be in this "other" persons best interest. At least by running rich it isn't going to detonate.

I don't know why one would purchase a SC from DDM and not use their tune. Trying to save a few bucks?

Critterman · « **Reply #7 on:** July 07, 2010, 09:10:47 AM »

I don't either, you aren't saving anything as the tune comes as part of the kit.

Lastoy · « **Reply #8 on:** July 07, 2010, 09:28:55 AM »

The werks tune was added at the nationals in Denver(2009) prior to DDM installing the SC this spring at thier shop.

Critterman · « **Reply #9 on:** July 07, 2010, 09:30:57 AM »

So is it running the Werks or the DDM tune at the moment, that is the important question?

Lastoy · « **Reply #10 on:** July 07, 2010, 10:05:50 AM »

I cannot answer that qusetion. I will have to let Kona chime in after he comes home from work. Do you know how to tell???? I would have figured DDM would have wiped out any previous tunes to make sure the sc would operate correctly.

WickedMike · « **Reply #11 on:** July 07, 2010, 10:38:48 AM »

Werks tune done at 2009 Denver nationals
SC installed by DDM winter 2010
Doesn't DDM tune override Works tune? If not then this could be the issue. Also had high flow cat installed and has SOLO dual exhaust.
We just want to get Kona running again!!!

Critterman · « **Reply #12 on:** July 07, 2010, 12:40:53 PM »

I replied on the big board things to look at and questions to ask.

JimmyBaja · « **Reply #13 on:** July 07, 2010, 12:57:39 PM »

Who's driving here anyway

Who's in charge

Who needs help

WickedMike, Lastoy, Kona???

We're trying to help here but everyone is talking in third person, maybe this is why DDM isn't helping. I find it hard to believe they won't help WHOEVER it is that needs help, I installed DDM's SC kit myself & Dave & Randy are more than glad to help whenever I need it.

GaryH · « **Reply #14 on:** July 07, 2010, 01:45:07 PM »

I have an automatic with the DDM stage II and a Solo hi-flo cat and Mach exhaust. Have not had any of the problems described here. It seems to run rich, but I think thats somewhat of a safety feature to prevent damage to the engine.

TecSolOnt · « **Reply #15 on:** July 07, 2010, 01:52:51 PM »

I have the same setup with the auto, same exhaust and have really no issues with my S/C installed by DDM and tuned by DDM. The programming on these cars is so important the first thing I would do is revert to a DDM tune just ensure the playing field is level if that's not the case. I don't understand the advantage of the Werks tune given his setup. I had talked to him about this issue he was having a couple of times at a Michigan run and at Canton, never mentioned the Werks tune or I would have said then to ditch it. The S/C cars do run a little rich, a little carbon out the back end is normal from talking to the folks who have them as well as the ones that follow me and see it when I step on it. The spark plugs look great on my engine when pulled so it shouldn't be an issue being a little rich.

The software on these engines is key, by example a few weeks ago my MAF was found to be contaminated (a cleaning fixed it) , the ECM software talking to the TCM started impacting the way my transmission was shifting, giving me some really hard shifts and acting like the breaks were being put on at low speeds, go figure. The software just didn't know what to do and when to do it based on the ECM readings off the MAF. With variable valve timing and the sophistication of air and fuel injection then getting that setup right is so important.

On a side note I did find that vacuum is extremely important to the tune working properly on the S/C, had to seal the tube that goes into the side of the S/C with high heat silicone as it was friction fit and kept finding a way to pull out of the S/C unit, this impacted performance pretty dramatically, including idle and high rev performance.

Good luck , I would find it hard to imagine that Dave wouldn't bend over backwards to get this working, does seem odd it has went on this long , thought for sure when I saw him at the DDM tent at Canton waiting for Randy to look at this issue that would be the end of it.

Critterman · « **Reply #16 on:** July 07, 2010, 04:17:33 PM »

I'm begining to think the Werks tune is a red herring in this issue a non starter. Unless DDM cannot write over the Werks. Kona needs to touch base with Dave at Works and Randy at DDM and find out.

don't know who did the install, but it sounds to me like they need to start on page 1 and run through the entire installation making sure, every connection is snapped into place and every bolt tighten correctly. Start there and see what happens.

Critterman · « **Reply #17 on:** July 07, 2010, 07:23:30 PM »

Talked to Dave on the way home, their internet is down aind he gets voice mail when he calls. Bill give Dave a call at the shop

WickedMike · « **Reply #18 on:** July 07, 2010, 10:49:26 PM »

Werk's tune wa installed in Denver as a performance upgrade. Then Bill decided to have a supercharger installed by DDM this spring. Assumption was that DDM SC tune would replace Werks but this may indeed be the issue. Dave has tried to to get this issue resolved and scheduled to do so in Canton but did not spend the time to resolve because he was very busy. He then promised to come to Bill's home since he would be in MI during the 4th.
It seems that Dave should be contacting Bill explaining why he was a no show and figuring a way to resolve this issue. I'm sure when Bill reads these threads that he will contact Dave, if he hasn't already. It is understandable that Bill is becoming very frustrated.

Critterman · « **Reply #19 on:** July 08, 2010, 08:54:26 AM »

We can speculate all we want on what he said, she said, bottom line is Dave and Bill need to talk, I know that if I'm having issues, and I am expecting an email or a phone call to set things up and haven't gotten it by when I think I should, I pick up the phone and call and find out what is going on. I also know that Dave carries his phone 24/7.

So my suggestion to everyone myself included is to let them work it out and we stay out of it.

WickedMike · « **Reply #20 on:** July 08, 2010, 10:18:19 AM »

Bill is not on this forum and has been contacted by Dave last night. Sounds like they are getting a plan together and Dave is sending Bill another ECM. Let's hope that things get straightened out.
Thanks everyone for the input you gave on both forums. Many good suggestions and that is what we were looking for. Will let you know results.

BTW, does the stage 3 still run rich?

Dave@DDMworks · « **Reply #22 on:** July 08, 2010, 10:26:12 AM »

Hello everyone,

I did give Bill a call last night and had a chance to talk to him about our trip to Michigan for the 4th and we came up with a good plan to get him taken care of from here.

Thanks again to everyone that has been trying to help with this!
Dave

Talk to Critter, he has the newest tune for the Stage 3 on his, so does Nighttamer. Both of them are seem to be very happy with the new tune though.

Thanks,
Dave

Critterman · « **Reply #24 on:** July 08, 2010, 10:40:00 AM »

Stage III - not that I can tell at all. In fact I haven't had to clean my facia since I loaded the new tune. And even better it has gobs of power
