This is for everyone that cant decide between an afc and a flash. Flash guanretees 20whp...how about 69..?

1st sheet is my baseline run with all mods, 2nd sheet is after all done with tuning. Mods this is in evo general to give deciding people an idea so please dont move.
*please keep in mind, this is not a dynojet, its a mustang dynamometer, gives real world numbers, for people who are not looking to show off, but to know what they really have.




Thanks to precision dyno tuning for the nice numbers!

 

Yeah, AFCII rocks, but look at you torque compared to mine... 207whp to 272whp, 215wtq to 268wtq... adjusting timing can't be beat, but an AFCII can usually pull a fair amount more of hp out of a car cuz you can be more exact, I am assuming Mustang dyno, cuz my graphs look exactly like those two.

 

Well, as you can see in my sig, I am a believer and follower of the S-AFC route, but are you sure that first time slip includes all those mods in your sig? You should get at least 196whp/190wtq in stock form, but it should be significantly higher than that with those mods uuntuned. The 2nd slip has numbers that I do agree are very good and seem to be well-tuned with the S-AFC, but I don't think the difference of 69hp is correct or directly attributed to the S-AFC.

 

He said his was on a Mustang dyno...I'm assuming yours was, too? If so, then it helps to re-affirm what I said in the above post questioning his 196whp with intake/exhaust/mbc.

 

Yeah it was... and that 196 is questionable with all those mods, stock mine was 207, I do know a guy that did 198 stock, but not with an exhaust and all that...

And I actually plan on someday getting an AFCII as well so I'm not knocking them at all (in case I come off that way) I'm just saying that they can't get quite as much torque as you can from a tune that adjusts timing as well as air/fuel, having two maps rocks though...

 

Head over to SoCalEvo.net to see how good the AFC really works. People are making some nice numbers with an AFC, injectors, fuel pump. Bigger injecors allow the ECU to advance more timing too.

 

Right, so I think this just shows that an S-AFC can provide tuning as well as a flash. Of course, the benefit is that he can add/change mods then tune on the fly, while you have to get a re-flash for an additional cost, but he also has less torque for some reason, so it's really a wash.

I just like how you both gained 65-70 whp with the basics.

 

Will do...I already love tuning with it, but if I can get some tips on how to get extra power like that, then I'll be elated.

 

Since I have a custom tune, I thought about maybe getting a AFC to fine tune with. I just don't like the idea of not having torque. I'd rather have more torque than HP.

 

EXACTLY the reason I plan on getting something else, and that something may be an AFCII, I've been told even by a shop that tried to get me to buy an AFC from them and have them tune it that ability to change timing is why there's more torque with a flash... but who knows for sure, especially since I've never seen them with THAT big of a difference in torque.

Plus the benifit that he can have a map on... say... crap 91 for daily driving... and 100 for racing, instead of just cranking up the boost like I get to do

And actually, I've seen a car's charts tuned at that named shop with 284 whp and like 260wtq with about the same mods as me and an SAFCII (my tq is actually a bit low cuz bad gas made it hard to get as much timing as we could)

 

Nice! I Think USING BOTH IS THE BEST! Then U can actually fine tune if you have a A/F Wideband

 

The first chart is with all my mods, im assuming the numbers were so low because the car was running pig rich.

 

That's highly improbable, if not impossible. Everyone runs rich from the factory and rich with those mods, but no one only dynos 196hp.

I think the point here is that you would have seen the same gains with a Flash as you did with the S-AFC, because you ended up right about where you're supposed to be with those mods, despite starting off way low. Flashes may claim 20whp, but that's just by itself with nothing else. As you add mods, the Flash is just a way to optimize those mods, so it's all relative.

 

Im just trying to state that I was among those torn between a flash or afc. Reason I got the afc, is because I dont have downtime with my car, and unplug the afc and your stock. Im extremely happy with it. I have no idea why I ran so low on my baseline pull, but at this point I dont care because Im making the power now. Torque will come when the money for aem ems comes.

 

Are you using a datalogger and/or wideband?...If so, who would you recommend?
