do you have a before dyno run to compare to?

 

no baseline run?

 

What happens when you use smoothing? That spike looks unnatural...maybe an extra 15-20whp just from that big spike alone. I assume this was on 91oct, since it's Cali?

What was the baseline dyno? Without that, it doesn't tell us much yet.

 

the baseline dyno numbers were not really a concern since that subject has been pretty much beaten to death. the main point was finding out if the afc was still an effective tool with the 9. the numbers were produced on 91 pee water with no tricks employed.

 

Hmm, but we don't know if it was an effective tool, because we don't have baseline numbers. All we see is a very erratic dynograph that has what appear to be high numbers, but with jagged spikes it's hard to tell. This could be 70whp over stock, or it could be 20...we don't know without a baseline pull.

 

1 question. How does leaving 30 or so ft. lbs. of torque on the table make an AFC an effective tuning tool.

 

The SAFC is the holey grail of tuning in so cal - its hard to reason with them about the SAFC over there

Using a SAFC to tune an evo is like using a sling shot to attack a bear

 

The top of this post stated that smoothing was set at 0.
Is that why the graph reads so choppy ?

I am a major S-AFC proponent, but after what I've learned, I am now able to realize how inferior it is for base tuning. Since I already had mine leftover from my last Talon and since I need the ability to tune for race gas in different situations, I'm glad I have it, but the recent base flash I got form Al made a huge difference just because of the mid-range torque. A flash is a much better tool for the average Evo owner who just wants a good daily-driven tune. The S-AFC is good for those of us who need the ability to change our tune for certain situations on race gas. Having both is serving me very well...

 

I would be worried about the 12.5 A/F ratios at peak torque with the way this ECU sprays timing all over the place.
Well at least he tuned the 9, its better than running stock.
Just work on the A/F

 

^^ That's hilarious.

 

Yes, having smoothing set to zero shows every peak and valley instead of smoothing them out into a rounded curve. If the dyno happens to have a spike around where you get max HP having smoothing set to zero gives you a slightly inflated peak power. On the other hand, if you have a crappy tune with giant spikes all over the place, setting smoothing to a high number will hide the fact that the tune is crappy.

If your base line pull was 275HP 263 lb-ft of torque then your tunning with the AFC is crap. If you base line pull was 210 HP and 208 lb-ft of torque then you are a tunning GOD.... so how can you say that the base line does not matter?

Everyone wants to see what other dynojet operators are getting for stock EVO IX's.... why won't you show the graph?

Oddly enough every flash we have seen on our dyno, including yours oh holy Al, have never been nice and smooth throughout the powerband. I can post those graphs too just to be fair. This wasnt meant to be a flash vs safc2 thread....so why make it that? We put the graph at sae and 0 so noone would b$tch and moan.
