New mod that will help EVERY RX-8 with flooding!
So we all know we battle flooding problems in the 8 when we shut it off too soon (oil temps not getting high enough usually). I am currently making a mod for our cars that would prevent us from shutting off the car until the oil temp reached a certain limit. (kind of like how you can't lock your cars from the outside if the key is still in the ignition). This would prevent cold shut downs that would in turn prevent flooding that leads to bad CAT's etc.
What do you think? Well regardless of what you think, i'm making this for my 8, but I will post a DIY up on here if anybody wants to use it. |
go for it!
so we would have to warm up our cars before we could go anywhere? |
I don't want to rain on your parade because in theory it sounds logical but flooding isn't really an issue anymore.
In 2005 Mazda made some improvements to address the then very problematic issue. New spark plugs Better battery Better starter Take all of that plus enhancements made through the aftermarket brands who have further improved on our ignition systems and flooding has been virtually reduced to a thing of the past. In 5+ years of owning my car it has never flooded, even when I TRIED to flood it. |
just take out a spark plug and light a match in the hole, flooding problem solved.
|
so you're making a turbo timer?
|
My 2004 has yet to flood and after I replaced my failed OEM coils with BHR coils, I made a point of trying to flood it but have been unable to.

I crank up and shutdown my 05 all the time for over 5 years and have never flooded.
IMO the only way to flood now is to have a bad engine in a cold climate, maybe also if you have an 04 with an early PCM flash that never got updated. |

except in this case it prevents floods by never letting you start the car

brilliant ! if you never start the car it will never flood :) |

I am saddened to see that it took until post #7(Zoom) for someone to actually comprehend what he wrote!
I will spare you the "Hello McFly" picture this time. |

anyone capable of doing a DIY like this, regardless of how easy it may be, will not have flooded their car in the first place
|
Like Red Foreman told me " let it warm before shutting it down, and you wont flood it, Dumb Ass". :)

Your premise is incorrect and a solution already exists for this particular problem. If it were engine oil temp related we would have been using block/oil heaters (ala Diesel engines) by now.
Oil tempertures causing flooding = fail |

Ha ha you beat me to the punch.
Oil tempertures causing flooding = fail The problem comes in adding a device that prevents engine shutdown. Not much use for the car's owner who already knows about letting it warm up. That leaves the occasional driver, valet, etc... While it could prevent flooding in those situations, having the engine refuse to turn off with the key could be problematic and cause all kinds of unintended consequences. |

Regardless of whether or not he understands the causality (not clear from the post), his proposed modification would still work to prevent cold shut-down, and therefore flooding. So it is not a fail in that sense.

As opposed to comprehending what he meant? :dunno:
Now you can throw the Hello McFly flag .... :kiss: I honestly didn't know which way to go with this one as there were too many options! :Freak_ani |

you understand EXACTLY what I mean. And that is what the Mazda dealership told me about the flooding issue. I'm still a newbie on the site and still learning. Bear with me.
A) Disregarding deliberately tuning it wrong, you can't increase fuel injection upon starting the engine. However, the ECU can, and does, richening up the mixture until the engine is warm, at which time it leans back. B) Ignition weakens all the time. Battery, starter, coils, wires, plugs. All it takes is one of them to fail just far enough. And none of ours are particularly good at staying healthy without attention from the owner. From my thread (so I don't keep retyping stuff) Flooding: Flooding is only a concern if you have a weak ignition system. The problem is, your ignition system usually fails very slowly, so it is a gradual decline. The alert and responsible owner will detect the drop in mileage, the drop in power, the rougher idle, the occasional misfire, and replace their coils, plugs, and wires before it gets bad enough where there is a chance at flooding. Every single flood I have seen reported for quite a while ended up coming down to one of these failing: Battery, Starter, Coil(s), Plug Wire(s), Plug(s). But by then, they also generally have a fried cat that needs to get replaced as well, and possibly an O2 sensor or two. Stay on top of the maintenance (long term included!) and you will wonder what all the fuss was about. Coils ($160 for all 4, 20 minute swap), plugs ($80 for all 4, 10 minute swap), and wires ($60, 2 minute swap), should be replaced every 30,000 miles, possibly sooner if you detect something starting to fail, since people have had them fail as early as 8,000 miles or 15,000 miles, though that's rare. You don't want to shut off while it's cold simply because when the engine is cold, the ECU dumps more fuel into engine to help it warm up, and it leans back once the engine is warm. This extra fuel can make it harder to start an ignition, which a healthy ignition system is perfectly capable of overcoming. Weaken the ignition with failing plugs, coils, wires, alternator, or battery, and you have a flood on your hands, and all the associated problems from that. So the "New mod that will help EVERY RX-8 with flooding!" is actually an old one... just keep your ignition healthy. |
