Failed inspection

[Stealth]

I have an edge evo custom tuned by Bill. He did these before he started doing gryphons waaaay back. He did me a custom 87 perf and 93 perf tune.

Last year I put on long tube headers. Bill told me a retune wasn't necessary. The LT's came with small cats and I ended up with cat inefficiency codes so I contacted Bill and he turned off my rear o2's so I could pass emissions for state inspection. I have since had magnaflow cats installed that are the same size most guys are replacing their stock cats with.

Well I went to get it inspected and my o2's are not ready. Friend of mine told me the rears might not have been turned off properly. Anyway, last week I sent Bill an email regarding this and haven't gotten a reply and I only have a few days left to figure it out. My main question is will it be safe to switch back to stock even with the headers to get my drive cycles in, in order to be ready for inspection?

Thanks Corey!

Still nothing. Anyone care to take a stab at this?

The only thing I can think of is doing a battery disconnect(with the tune loaded and programmer disconnected, then hook up the programmer after the battery is reconnected) and completing a drive cycle again....something in the EVAP system might be the issue.....Bill omits the p1000 but none of the other drive cycle tests are omitted...

I'm not showing any codes stored on the tuner. Before the tune adjustmest and after the header install I got a couple of cat inefficiency codes with a light on the dash. I had bill adjust the tune to turn off. The rear o2's so the codes wouldn't come up. Since I knew the cats were small I put on the larger magnaflow cats. Never had an issue before with inspections and bills tunes. So will I be ok setting to stock for the inspection after drive cycles???

Just leave the custom tune loaded.....reset pcm....do the drive cycles....

your programmer cannot read if the tests have cleared...there's another scan tool for that....

[Stealth]

I'll try. Hope it works. I can't afford another $40 for inspection being out if work right now.

The codes that I had were p0420 and p0430. Bill adjusted the tune to turn off the rear o2's so these codes wouldn't arise. After he did that the codes never came back. Fast forward six months to now and I have better cats and the cayalysts and o2's read not ready on the inspection report. This is why I believe the rears were not turned off in the tune properly. It is my opinion that returning to stock would be my best bet vs trying the same tune again. Opinions? I need an answer soon. lol

I left Bill a note....

[Stealth]

I will try that.

[Stealth]

Tow tune that is. I'm taking the truck to walk the picket line tomorrow morning and that's a fifty mile round trip or so and we will see if anything pops up.

Bill,

I made a small update to the file which shuts off certain OBD II monitors pertaining to the O2 Sensors. This MAY work to help you get through emissions. However, when disabling the monitors, the testing equipment may see that as an error and still fail you. It all depends on the testing equipment.

The download is available at your convenience. If this does not resolve the problem, then your only other recourse would be to change the CATs again and reset the O2 sensors back into the tunes.

These emissions testing places are getting to be so friggin' difficult. Why can't they just sniff the exhaust and go? I could just about guarantee that you're running cleaner than anything required by the EPA, regardless of what the "system monitor" says. But, it's all government interference to protect us from ourselves. :doh:

Let me know how it goes.

On Edit -

Actually, after re-reading your posts, I went ahead and reset the O2 sensor function back to normal. That update is now available in Pegasus for download. :2thumbs:

[Stealth]

Ok I downloaded the files to the tuner and am in my truck loading the 87 perf tune into the PCM and initializing communication is all that is on the screen and it seems to be stuck there. Any ideas what I should do?

[Stealth]

The screen is frozen. I disconnected the tuner and the truck starts on I assume the stock tune since I set back to stock before I downloaded the new tunes. Any ideas?

If the tuning did not complete, you're still at stock. The "hangup" you describe sounds to me like it could be a weakening battery - one that still has enough power to crank the engine but that doesn't have enough for the programmer to generate the 18V signal needed to tell the PCM to accept a new tune.

If you could put the battery on a charger for a while before retrying the tuning process it may then work. And, if you have a charger capable of providing a "trickle charge" (usually 2 Amps or less), I'd just leave it connected while you try programming.

Sorry to hear about you being out of work. That has to really add to your stress level right now. Hope things turn around for you soon.

Battery is good. I've been loading and changing tunes in the truck for a few days now and it's worked fawlessly. The tuner is locked on a green screen and non responsive. Pegasus won't recognize it any more either. I recall this same thing happening the last time I had downloaded tunes and Bill had to remote desktop my tuner to get it back up to speed. I think this may be the case again.

Yes we are going on week four of strike starting Monday. Saved money for strike so I'm not stressing too much and we're picking up some money from odds and end jobs so we are knocking out small bills as we go. I'll say this, painting the house is a pain in the keester! lol

Thanks Jack, and thanks Bill!

OK Will -

Hope Bill gets back to you soon. It sounds like something corrupted in the firmware then and, Bill seems to have to fix that "hands on".

Just letting you know Bill the truck passed inspection on the stock tune. I got a good amount of windshield time in this past weekend plus towing the boat to the lake and back today (caught a mess of crappie, fish fry will be good) so I ran her up to get her rechecked and passed. Once we get my tuner unlocked and the tunes reloaded all will be good once again. Tuner froze up upon trying to load the updated tunes into my truck and it is stuck on the green screen (see previous posts).

Let me know how you want to handle this. I've got nothing but free time, when I'm not fishing, that is. lol

[Stealth]

Bump.

[Longshot270]

You could fire up Pegasus, plug the programmer in and do the custom file download. Sounds like something didn't go right last time you got tunes.

[Stealth]

Truck's been running fine on the stock tune. Of course I miss the custom tunes. :P

[Stealth]

Longshot, the tunes downloaded fine. The tuner locked up upon loading them into the PCM and now Pegasus won't recognize the tuner as a result.

[88Racing]

Argh.....left a note for Bill....

[Stealth]

Still nothing yet. I'm thinking of just sending the tuner in with a copy of this email and explanation of what needs to be done.

[Jackpine]

Will, that seems like an "extreme" measure. I think Bill's been VERY busy and "distracted" lately, judging from what I'm reading here. I'm sure he can fix your Gryphon without you sending it in, but I suspect he might have to take remote control of your PC and do it "in person" - all which takes more time. I'll see if I can "nudge" him too. I see your phone number is in your !profile, are there better times than others for him to contact you, or, could you possibly try to reach him using the "live chat" feature (which might be better)?

- Jack

[Stealth]

No, you misunderstand, Jack. It just seems to me that sending it in would be by far the simplest way since they are always so busy with their business and family. I do not fault anyone but myself for this. I'm the one who keeps modding my truck and am more than thankful for all that Bill has done for me, and for free at that. I'm probably the customer who has gotten the best deal in PHP history.

[Jackpine]

OK, but I did post a note to Bill in the moderator's forum. I DO think it's something that could be fixed "long distance". However, I'll bow out and let you handle this in any way you want.

- Jack

[Stealth]

I do too as I brought that up a while back. I just don't want to take any more of their time than is necessary.
