L99 Holding off For Now

GM offices are in shut down right now. No one there to work on my car.

Fbodfather told me not to unplug the battery. They want to see what is wrong with the car and that will clear sub-codes that are still there that will not throw and engine light.

I know its a long shot, but it might be worth trying.

You could also try disconnecting the MAF and let the engine run in a closed loop system to see if performance gets better (which it shouldn't but if it does, would indicate a problem, conversely if it even stays roughly the same could indicate a problem)

Seeing as its difficult for you guys to get em in to the dealer (totally understandable) these small things could at least narrow the scope as to whats wrong, and you can do them yourselves over the weekend

just a suggestion

Hope your issue gets solved soon

Well. It's the weekend now so I can try some things and test some things. If the iPhone app is close to accurate, my car seems to have healed it'self. Can't wait to do some time tests. If I get any times over 6 secs to 60, I'll be putting it on a dyno. Screw it. I'll just bite the bullet. No reason for Scott to have to spend the money, he's got enough 'bills' as it is with Steph.

Either way, Tuesday I'll have some updating.

A disabled system or sub-system, causes the computer to run in open loop. Closed loop is when everything is right, hot, etc, and the computer uses the O2 sensor(s) to adjust fuel mixture and other parameters.



There's one backyard test for this problem, and that's getting a Hennessy tune on a separate PCM, and seeing if they run better.

Otherwise, let the dealers and GM (Fbod) sort it out. Use a stopwatch.

putting in a tuned pcm, and likely trans tune, from hennessey---=will make all the stock cars feel bad, give your head a shake.

Are you sending them a spare pcm... or are they providing it. I'm VERY interested in how yours turns out. Keep us posted...

My bad, you're totally correct on that one

Anyways....any updates?, or are we all waiting until Tuesday to hear anything?

lookin forward to tuesday...

I have always heard that cars have better fuel mileage and performance after they are broken in.

Yes gradually but not a sudden oh I hit 3000 miles now my 0-60 6.5 second SS that gets beat by a V6 will now run a 4.8 0-60

[2010cantwait]

1100 miles on my L99 and I already feel it loosening up a little; this one runs GOOD......

Sorry guys but those of you bitching all day on the forum about under performing cars need to get your a$$ to a dyno. Period. Take some of the hours you spend on the board(s) and drive to a dyno. I realize some may be far away, but dammit take a road trip. If it is so freakin slow you better beleive i would take the thing to a dyno to prove my point to GM, so that they would either fix it or replace it. I mean spending hours on a forum bitchin isn`t going to solve your problem. Otherwise all your doing is stirring up crap w/out any results. Just running another car does show yours is slow but DOCUMENTATION (dynograph) is your friend....And will show EXACTLY and irrefutably how down on power your car is.

I don`t mean to come off harsh but I`m tired of reading these threads w/ no real action by those upset w/ their cars performance.

Just for the record, my L99 feels pretty strong. I have a Vette to gauge it by and while not as fast as the Vette its not far off. I will be going to the dyno in about 2-3 weeks to get a baseline before the mods begin. I`ll post up at that time the results. Oh and I smacked down a 5.7 Hemi Charger the other day...

[toehead93]

I've been going nuts myself reading this stuff too. I agree, get a dyno so we have hard evidence, otherwise it's pure speculation. And when he says dyno he is not refering to the "butt dyno", we have seen enough "seat of the pants" testing.

Can we get a "no more butt dynos" smiley?

First off "but I`m tired of reading these threads w/ no real action by those upset w/ their cars performance" if you read the thread you would know that Scott and Irpq11 have taken action to resolve these issues, with scott even having been in contact with Fbodfather, and doing a perfomance assesment with a v6 car....basically a drag race...but w/e...the v6 won, indicating an issue....and this was WITH the dealer, so it is obviously an action taken to resolve the issue

Secondly, why should they have to shell out their own cash to fix a problem with a brand new car, when clearly their performance is far below where it should be, and far beyond just a subjective dissatisfaction with the performance

Lastly, "Take some of the hours you spend on the board(s) and drive to a dyno. I realize some may be far away, but dammit take a road trip"

It is a bit unnrealistic to expect that all people are even able to find enough time to do that. I also think that it's a bit unfair to Scott, albeit possibly out of ignorance on your part in knowing his situation, as he not only must juggle work and his family, but his daughter has a serious medical condition which requires a great deal of his time and attention

So before you go criticizing people for their reports of issues with the car....---and thats what they are reports... as Scott and Irpq11 have never complained or b!tched about it, only brought the issue up so it may be brought to light and resolved...----read the entire thread

Guys, please be patient. The rain has me derailed for time tests. It's supposed to rain all week. I'll just have to get back to this as soon as it clears up a while. I don't want to do the tests with TC on. I might anyway but don't want to.

Mine seems to have considering my last test but it was just one run and I subsequently reallised that it was dark when I did the run and after going back in the daylight there is a slight down hill grade for about the first 60 to 100 feet. It actually has about the same grade uphill the rest of the way but it probably contributed to a better than normal launch for that distance. 1.5 second difference, but not accurate.

Point one. I am on the boards because I enjoy the site and am stuck at the office. My business requires that I be here. Just because I own the company and post here alot doesn't mean I have time to do what I want around town.

Point two. Glad you DO have the time during the day to do this. That's great, really. But what makes you think GM will accept the numbers from an outside Dyno? I'm willing to bet they wouldn't.

Point three. It has solved problems in the past. Others become aware and can offer some advice. As a matter of fact, Junkie has my car running better allready. All by giving me some advice on the side.

Point four. STOP READING THREADS YOU DON'T WANT TO READ!


Have a nice day.
