Post DSM AFC Dyno Results

HAHA....roscoe peco train will be on your tail.

Dyno run scheduled for Monday at 10am. The guy said I can do one run at stock boost, change the MBC to 9psi, and possibly get a third run in with my custom map. Guess we'll see. Now I have A LOT of work to do this weekend getting the MBC in, exhaust tightened down and gasket put in, Dynamat install, and now I need to get the map tightened down too. Guess I can do the map and MBC at the same time, since both will require street runs. Hopefully the new exhaust won't have the stupid suburbanites calling the cops on me.
 
Well, with those numbers, add in an exhaust and minus .5 psi, I should be able to make 205whp/205wtq. That is what I am hoping for. Plus it's cold as hell out right now, which should also yield higher numbers.

Too bad I don't have the $$ to buy the MAP sensor I need to log boost with the WBO2. Otherwise I could nail down my new map in two or three runs. Just for kicks I'll post up the A/F graphs in the AFC thread to show everyone what they do with a stock exhaust, one with adding a Vibrant exhaust, and one with upping boost to 9psi, all with the supermap ... then with my own tweaked map.
 
Well, I was going to do a run at 9psi, but I tried to put in my MBC today and I was boosting to 10psi and above. I couldn't get it to work correctly at all and I followed the How-To to the T. I spent most of the day working on the Dynamat install, so I couldn't get to the map. I'll attempt some runs tomorrow morning before the MEC brunch tomorrow morning. I have some wiring to take care of tomorrow as well. Stupid busy weekend.

Anyone know the quickest way to tap into the cigarette lighter wires without tearing apart the center console?
 
Also, the stock vacuum lines SUCK ASS. They are so brittle I was nervous installing the MBC. I think I'll get one of those vac line kits from Crossover this spring.

Maybe when I sober up I'll do some runs and get my fuel map tightened down to 12:1 flat.

Current results posted. Figured I would just keep a single thread and update it rather than keep creating new ones. Results were kind of disappointing. They did this pull in 4th gear instead of 3rd like all the other runs, don't know how much difference that will make. The gear ratio in the file is a bit different, but I don't know how it will affect the readings. If they would have kept the same settings, I'm betting my numbers would have been something like 183whp/178wtq.

With a properly tuned map I could probably get it to about 185whp at stock boost levels. Next step will be to get the Zietronix map sensor so I can log boost and get my map nailed down. You can see how lean the supermap is running though.
 
When did you dyno?

I see no results :)

NM...they are there now, I was to quick!

I updated the first page, sorry for not putting that in my update post.

I don't know which A/F to believe, the shops or mine. Here is a graph of my A/F I logged yesterday with the same custom map I just ran with.
 
179whp at stock boost is pretty darn good. If you would have ran at 9psi, you would have gone over the 200whp mark.

Nice work, and thanks for all the comparisions.

Can you email a copy of the run with the super map and the vibrant?

Thanks,

TurfBurn said I've been using the wrong correcting factor with my run files. He said the "standard" is STD correcting, so I updated the numbers in my signature to reflect the new numbers. I'll post new graphs when I get home.
 
My Dyno results (copy of post from earlier)

Ok below are the charts. I got rid of the other lines and left just the first run with the original map and then our final product. On the TQ the dark blue was the starting run and the aqua was the final product.

We couldn't get the AFR's super imposed at the time. If you guys really really really want those charts and the demand is high enough for them, I can drive the 40 mins back over with a floppy and get that chart for you.

But if you can do me a favor and take my word on this, the A/F is roughly 14 until we hit about 2 psi. Then it drops sharply to 11.3 and then varies from 11.5 to 11.9 with the average being 11.8 all the way through. My dyno tech spent hours fine tuning the curve and made an impressively smooth line. In the end he only charged my for 2 hours.

Now you may notice that on the TQ chart, it appears that we lost TQ on the highest end... we know that is incorrect as a matter of fact impossible because we were hitting 195's at 6K all day and when that reading was taken, we were done messing with the high end numbers over 2 hours before that. We NEVER had to adjust any voltages above 6000 rpms.

The engine was getting heat soaked and the blower he had sitting on top of the engine between runs was getting too hot. I would have had to swap out the manifold blower and wait 15 mins to get that peak to be accurate again. I wasn't about to spend $130 for another hour just to see something I knew to be true.

Overall, I was slightly disappointed, I really thought I was going to break 200hp... I have modded out the car almost as far as I am willing to go. The only step I can do now is WRX injectors and retune.

I posted your results on the first page of my thread, let me know if those readings are wrong, it was kind of hard to read those dyno charts. If you have the dyno files I can create some better graphs for you.

I just have the graphs on paper that I scanned. On my computer if I zoom I can read it fine. But if other people can't read it then I need to fix it. I could try to rescan at a higher resolution...
 
Stock boost before exhaust = 7psi peak, 6psi hold
Stock boost after exhaust = ~8psi peak, 7psi hold

Of course this is according to my Autometer boost gauge, who knows how accurate it is. Some day I will get a MAP sensor from Zeitronix and get the real boost readings.
 
Bumping old ass thread.

When I dyno'd I my Autometer was reading 7psi but the AFC log shows 6.1psi via the MAP sensor. I'm sending my gauge off to be recalibrated. Results were ~187whp/202wtq@ 8-6psi bleed. FMIC, TBE w/ cat, K&N, AFC w/ SuperMap. A/F held steady around 11.8:1
