Alright I know that it is pretty common to have misfire problems or whatever with 60s. But this seems to be something else cause I don't throw any codes. I'll pull up to a light and maybe 10-20 sec after pulling up and idling. My car will start to shake quite violently for about 3-5 sec than back to normal idle. It doesn't do it every time. Just prolly 3 out of 5 stop lights. The Wideband will be hanging around 14.5-14.8 when idling normal than it will lean out and jump up to 19-22 when it starts shaking. Any ideas what this could be? Tuned by Fast98 BTW so I'm pretty sure the tune is good.

 

Let me guess, it only does it once it's warmed up, right?

It's the tune. Mine did the same thing until I adjusted the short pulse adders, but it's a little hard to tell for sure without a log.

 

put the rear 02 back into the system
set the cot temp thresholds back to stock. hope and pray it goes away. but it won't

 

I haven't really paid attention to that, but now that I think about it. I believe it is.

The rear 02 is still in. Do you have the problem or no?

 

i have had the problem for about 40k miles. i don't care anymore. have the cot temp threshold tables set back to stock it will help it. won't cure it however

 

07 FTL.

i'd work on offsets, then min PW.

 

even with a gm based 79lb map it still does it. the 07 OS has more check **** in it for emissions and other things than any other car. same people didn't do the 07 OS it was farmed out by someone else. another reason why we don't have trq mngmnt tables, and random freak outs here and there.

 

Interesting. So I just got to deal with it lol.

 

Now that you mention it, when I changed the PW adders and min PW I also copied over SJShafer's 60lb offset tables so that could be it as well.

What's the difference between 07 and other years? I had heard it had differences but haven't had time to look that much at the 07 SC I pulled the other day.

 

Yup mine does the exact same thing and I have a 07 as well, I don't really care anymore, it sounds kinda cool like im cammed or something lol

 

lol. A buddy of mine said it felt and sounded like my car was cammed

 

yea i just smile at ppl next to me and im like yea, dont **** with this!

 

destroyed by trans tq mgt!!!!!

 

dont even get me started on my 07 issues w/ boost lol..

but my car does idle quite fine on 60's.

 

yeah brandon its just cat-over temp protection. when it starts to shake like that you can just blip the throttle and it will go away

 

actually it's not. it is a combo of multiple things.

 

really? didnt know what else would do it. why does it smooth out after I blip the throttle off idle?

 

eh. 06 FTW.

 

eh...05 ftw

 

06 FTW> 05 FTW

You coming to the track Thursday so I can make this statement true?

 

hey braulio, so when is terry going to take off "Central FL's Fastest" from under his screen name?

 

TONIGHT IS HE WANT

 

When someone can beat me without having to use Nitrous and slicks....

See you guys Thursday...

 

yep the bottle is full just for you

 

04-06 GMPD were responsible for the calibrations, thye used some clever Lotus Engineering staff. In 07 mainstream GM Powertrain took it over, and some emissions/fuel economy/other stuff not worth imagining that none of us poor folks care about, were added to the mix. No stage 3 for 07. Gradually it becomes a whole new ballgame and thanks to some smart tuners (area47 among them) it has become possible to make the best of it, within the limited capabilities of the tuning software...
