How rich can you run the car and it being safe?
Turning up the fuel richness in WOT, +2? +4?

 

[ajm]

Why exactly are you trying to richen it up? No use in throwing more fuel to it unless you have a power adder, and even then theres way more to it than just richening it up.

yeah im not sure im understanding what you are trying to do. :dunno

 

[Cesar2cool]

Feeling kinda laggy during WOT, Some are tellin me to try and richhin it up

 

[ajm]

Guess you dont have a wideband do you? That would be the best way to know if it really is running a bit lean at wot or not. What mods? Unless you have something fairly involved I doubt the problem is in the tune.

What do you mean by laggy? Jerks around on you and such?

 

[BakerFX4]

thats not going to do it i dont believe.

I wouldn't really adjsut fuel much without a wideband to be honest.

Running CAI,TB,Plenum,plenum Spacer(For shits and giggles),BBK Ceramic Shortys,O/R X Pipe, Flowmaster 44's,3.73's, with SCT Custom 91 Octane Tune.

I hightly doubt its in the tune. You really dont even need a tune to run those things. Sounds like its something with the car its self. Who knows though.

 

[Cesar2cool]

Would it hurt to run rich tho? Like richhin it up 2 points? 4 points?

 

[ajm]

Sure go ahead...its not my car....read what weve been getting at above...doing so w/o a wideband or really knowing what youre doing really isnt that smart.

 

[BakerFX4]

LOL^

im just tryin to make a quick fix

 

[ajm]

no more than +/- 5 on each bank

It won't hurt your motor to richen it up, but it won't help anything unless youare already running lean. You have no idea if that's the case, so leave the fuel alone. If your car is acting up, unless you just installed a new tune or something and it's been acting up ever since, look somewhere else for your problem. Tunes just don't go bad overnight. They aren't shrimp scampy.

And really chances are thats not even the problem. It would be understandable on a car that had long tubes or cams at the least, but with a few simple bolt ons that can be ran 100% fine off of the oem tune rarley is there a problem with the aftermarket tune.

If you really truly believe it is something with your tune though just put it back to the factory tune and see what that does for you. Beats adjusting stuff you dont know about/know if thats even the problem or not.

+1, if you don't think you are getting enough fuel change the fuel filter. Tunes dont magically give you less fuel, it stays the same (and leans to the ideal).

Also keep in mind if you are rich, you will have less power. So troubleshoot :tomato

Ok your talking about the SCT tuner.

Try +2 and see how it feels. If you like it then ta da. If it feels better go to +4 if you think you need it.

Just FYI, i put mine to +12 and i was running a 9:1 A/F

Gasoline stops igniting at like a 7:1
