[FONT=Comic Sans MS]I guess its no longer a figment of my imagination that the trunk space on my RX8 seems unnaturally hot.

I find it fascinating that the Repair Procedure - Inspection - step 2 says that if the grommets are not damaged, then don't bother with the tank inspection and go directly to the reflash. That seems on the surface to be very presumptuous?

They've gotten it to the point where a simple ECU flash will accomplish what would've taken parts-swapping in the older injection cars, and hours upon hours with a screwdriver and a length of hose with a carb'd car. You can thank the gub'mint for all this emissions-control. Trust me. It's a lot better today than it was 20 years ago. Let's not even discuss cars from 30 years ago. Stuff of nightmares. |
Screw it. Just give us 3 rotors in an 8 and sell it for an extra $5k. I'm sure it would sell. I would buy it.

im sort of wondering why standing still at high revs makes this worse then just driving at high rpm. I mean I doubt there’s that much air getting to that specific area while your moving, and once your exhaust is at temperature I would think that they stay at a pretty constant temperature moving or not.
Also I'm assuming the new parts for group one have some sort of modification to the tank that makes them resistant to this type of damage, what im concerned with is what there doing with the reflash.... The only way to make exhaust temps cooler is richening the mixture which isn't what we need. we have a right to know what these flashes do its rather frustrating..... |

i read the whole thread.. just point me to where you answered what R flash does lot nicer then telling me to look....

If the muffler filled with fuel and melted the body plugs there is a great chance the car has flooded at some point. The retailed car inspection process we be similar to the dealer vehicles. Thanks Gomez for keeping us up to date on this issue. |

If MM keeps the nomenclature for the 2004 cars, the "R" for the hipower is outdated.
SW-N3Z1ES000 has arrived at the motorcraftreprogrammingpage. But no SW-N3Z2... for the AT. |
^dang, with the 'S' flash now out, The ultimate 'Z' flash is just around the corner ;)

Any new information on the Group 1 cars? I visited my baby twice this weekend, we are both getting very antsy. It gets me worked up every time because, I know I have to leave it in the lot.
Parting is such sweet sorrow. :( |

polak and others-
i was wrong! shocking i know:) it is S flash for 2004 cars SW-N3Z1ES000. and i think i know the change it makes but i need to check. if im correct it removes an action that could cause a high idle in the first place |

This is not good news. I live in TX and have the Greddy turbo which increases the temps even more. I'll wait and see what they say the prob is. I may just have to get a sportbike and keep the car in "summer storage" :rolleyes: . |
I appreciate all the info that is being shared on this thread. It is one thing about owning the 8 that makes it so cool.
The underbody temps have to be high in hot climates--thats common sense. But the heat that is causing the problems are from the fuel burn off in the cat/pipe/muffler due to flooding or near flooding? Hmmm. So cat damage may be prevalant in many more cars than previously thought? Someone educate me here. Is a cat one of those things that either works or dont work? Can you have a partial decompensation? I know my RB cat back has clouded this issue for me(thanks for that info) I remember when I had the stock muffler on and it was much hotter under the back of the car then. I also wonder with the cz unit and people leaning out the a/f ratios whether that had a good affect or a bad one. I know Mazda is saying low speed high rpm stuff and cz really doesnt work til you get into open loop mode but at this point I guess it is just natural to wonder about that. Wouldnt it be nice for them to put a high flow cat on for us and leave the stock catback on? (Much quieter that way) With the freer flow maybe the temps would go down? I have been under my car a bit and it already has a good bit of shielding in place. Sure gets hot in the console and ashtray area when you drive around town. There is a big differance in airflow with this car under 50mph/stop and go and over 50mph cruising. I await the plan for the group 1 cars! Olddragger |
I'm no expert, but from my experiences cats, can go bad over time and eventually get plugged up to where no exhaust flows.. I had cars where the cat was so hot they would glow red at night and catch grass on fire. Other's just lose thier elements and don't clean much air and rattle.

The only piece of stock plumbing left on my car is the exhaust manifold log. I wonder what temps I am running at the back end? I'm doing a visual tonight and se what I can find. I also need to schedule the 30K service, and I am Group 1. I don't want the dealer nabbing my car for a few days :(
I'll go talk to my little birdie and see what he says :) |
let us know the song your bird sings dude.
OD |
Group 1 here, one of the first to buy... I wonder what the plan will be...
|
:confused: How do you know if you are group 1?
|
It's been about 105F+ for the last week I sure hope my gas tank doesn't melt and my rx8 explode that would SUCK.
