OK, while we are on the topic of tuning, what do I need to tune my rx-7 properly? I know I would need some kind of fuel control, whether it be s-afc or fuel controller replacement, but is a wide band o2 sensor REALLY necessary? is there a way around having to spend loads of cash (besides s-afc, which I may do) to get it tuned right? I probably will not have cats, and I don't want my car to smell. especially seeing how the turbo timer makes it idle in place for a while.

Isaac,
I think we're basically on the same page as to what a tuner is. I think money is important because it gives you the option to try different setups. If you don't have enough money, you could also be a tuner, but e.g. $75 a week would take a long time to build any experience. Anything is possible.
I don't consider myself a tuner either. I might consider myself to be a suspension tuner, rather than an engine tuner, just because of my experience with racing.
I thought I might add that the inefficiency of the rotary engine is also due to large, spread out area of combustion chamber. I wrote my English 200 paper on the rotary engine. I got a D.

To avoid detonation or to meet emissions requirements, probably a little of both? So, like you said if you don't know all the facts keep your mouth shut. The whole truth and nothing but the truth bro.

As you stated, rotaries are tuned rich from the factory, more so than other engines. Could this be, as history shows, that rotaries are not as clean running as piston engines (in some respects) and that is why they have to run rich to pass emissions? Wouldn't that mean that in stock form the fuel settings on a rotary are set to run more rich than others (we already knew that), thus they create more of a smell than others, and the smell is amplified more so when the exhaust is opened than on others? Huh, so one might say that rotaries are "by nature" a more stinky engine in stock form? I think I proved my point.

Rotaries are by nature not stinky. It is how they are factory tuned to be too rich that makes them stinky. If you would tune your car to run properly, then it wouldn' stink. But then, by your ideal, your engine would be unnatural.
Its not the engine design that makes them stink, its how they're tuned. So again, rotaries, by nature, do not stink. Care to retract your statement, or will you continue your ignorance?

Can you read? As I said the Series 1 RX-7s were set to run very rich to help with the operation of the thermal reactor, did the reactor aide in meeting emissions requirements? Yeah, I think it did bro.
Actually from the start I was refering to stock rotaries, I consider modifying an engines fuel mixture to be just that a modification on the engine. Anyone can modify an engine to run more lean, will it neccessarily be good for the engine.....um no. Stock is the "natural" form of an engine. So, rotaries do run more rich and do stink more. Need I say more?
I think you should be the one considering to retract your statements, the only one suffering from ignorance is you dude.
But seriously no need to get so worked up, the internet may be your life but people will like you for who you are and not your internet persona,

No, I won't tell them that, because I think rotary engines are by nature more offensive in odor than an equivalent piston engine. Isaac

Do you have experience with all rotaries? Third gens? 20B's? REPU's? Renesis? You're clumping togther an engine design by how it is in two cars. This is an incorrect assumption.
You say from the start you were referring to stock rotaries, but as a journalist you should realise that you have to state that, otherwise you make an untrue generalisation.
The 787B rotary ran no cats, and it didn't stink... so I'm guessing it wasn't a natural rotary by your ideals then?
Face it: Your car stinks b/c you're too poor and cheap to get it running properly. Make fun of me for talking on the internet all you want, but maybe you should get your car running properly before you go making fun of others.
You're trying to argue with me over a point I'm not trying to dispute. I agree, that RX-7's, in stock form, run rich as tuned from Mazda. However, you are wrong in stating that rotary engines, by nature, stink. And to continue that argument does, by definition, make you ignorant.
This has been my argument all along. Funny how you asked me if I could read.

I honestly dont know what you guys are talking about as far as them smelling. Ive smelt a FC with no cats and it smells like something you'd smell at the race track or at a carting event. Nothing like rotten eggs

-Do you have experience with the Renesis? I said rotary engines smell because I've owned 3 of them, I have friends with RX-7s, REPUs, and even third gens. Oh yeah, did I mention that they smell too.
You say from the start you were referring to stock rotaries, but as a journalist you should realise that you have to state that, otherwise you make an untrue generalisation.
-Of course I was referring to stock rotaries genius, why would I refer to modified rotaries? That is not something you can make generalizations about because of the fact that they all vary widely in how they are modified.
The 787B rotary ran no cats, and it didn't stink... so I'm guessing it wasn't a natural rotary by your ideals then?
Sorry to break it to you pal but race cars don't have to worry about their emissions. The 787B doesn't have anything to do with this argument because it wasn't a production vehicle. It was built for racing and should be considered a car with a modified engine, not stock=not part of my generalization.
Face it: Your car stinks b/c you're too poor and cheap to get it running properly. Make fun of me for talking on the internet all you want, but maybe you should get your car running properly before you go making fun of others.
-Actually you are the one who started this whole little flame war, don't you have anything better to do? F.Y.I. I'll worry about tuning my fuel mixture when I start heavily modifying my car (porting, ect.) why bother setting it now? Is the risk worth the minimal gain at this point? All I have is a stock engine with a couple of bolt-ons, and the smell doesn't bother me all that much. I guess we all can't be as rich as you, lol.

-So tuning an engine and ******* with the fuel mixture, thus modifying the engine should be considered the true form of the rotary? I don't think so. The stock form of an engine is the true form.
