Unofficial Dezod Dyno...
I just wanted to post up a street tune I did with the Dezod S1 kit. Lemme tell you that getting the Injector Response Time right is a must. With the Deatschwerks 550's I used 1088us for the response time. It is sooo much better now. Originally, with the basemap I received, it was set to 586, I believe. Thanks to Paul@Dezod and Mike@Deatsch I got this thing down pretty darn good. Idles at 14.8, 12.5-12.0 building boost, then mid 11's at full boost. I just gotta lean it out a little above 5k, but she's running strong. I say "unofficial" because it is using the DynoMaths library I got from the AEM forums. The weight/tire size/gear ratios are all correct, so it basically acts like an in-car dyno, pretty cool. I will do a real dyno in a month or two, but for now, this measures gains/changes plus it basically does the same thing as long as you are on a flat road. Okay enough of my banter, here ya go! Good looking curves, 289wtq/265whp.

Yeah, I don't post too much, but I try to help when I can, I am more of a reader...HA...Man, I can't tell you how many hours I have spent just reading through forums. I think SL keeps track of how many hours wasted, but I don't think I really wanna know.
Marcelo, basically you follow the how-to on this page...http://forum.aempower.com/forum/inde...ic,2279.0.html
It will show you how to set it up, but for the fine tuning to get it right for the TC, I can post up the variables that I use.
EDIT:
Okay I have time anyway so here are the values I use in the library...
MAKE SURE TO LOG INTERNALLY WITH SAMPLE RATE @ 10ms!!!
ALSO, REALLY MAKE SURE THAT YOUR RPM IN LOGS AREN'T JUMPY, CALIBRATE THE DAMN THING!!!
WHEEL_SIZE: 17
TIRE_WIDTH: 225
TIRE_ASPECT: 45
GEAR_RATIO: 1.33 [This is 3rd gear, basically you could use any gear, just look up the gear ratio of the gear you used]
DRIVE_RATIO: 4.235
CD_DRAG: 0.32
CD_AREA: 24.2
WEIGHT: #### [For the weight, I would suggest to go to a place that sells bulk rock/gravel and they should be able to weigh your car with you in it. If you can't find one just add the dry weight of your car, plus the weight of the gas, plus your weight. That should get you close. And it is in POUNDS(LBS.), by the way, not kilograms]
RPS: (FILTER 50Engine Speed)/60
DeltaRPS: DIFFERENTIATE 25RPS
Filtered_HP: FILTER 20Raw_HP
^^^These should be the only equations you should have to modify, nothing else^^^
Oh and the download for the library is in a post somewhere in the link I gave, not sure which page. I could also email mine if anyone wants it. Just PM your email addy...

Oh yeah, forgot to mention that this was tuned on an AEM F/IC. Hey Chris, any word on tapping the knock sensor wire to log the voltage? If that doesn't work out, I am just gonna fab up an e-detcan and hook it into the stereo of the car...knock, in stereo!!!

I almost thought this was with the dezod ems.. pretty neat cool though.. But yeah injector response would make tuning and retuning so much better, you should put that first before doing tuning and you will have a more correct fuel map

if you tuned for it most likely you wont.. when you retune or do mass increase decrease in % fuel across the power band most likely you will have different boost and cruise afrs as before.. usually lean vacuum too rich boost.

The problem I was having was the percentages I was having to input into the fuel map. Yes, my car ran for about 1.5 years with it set to 586us, but I had to compensate for it in the map, which made hitting target afr across the range pretty darn hard. Now that it is right, I don't need to compensate for it, which means a flatter afr, and less variation in the cells of the tune. Fuel trims are also spot on, +/-5% when driving normally, and up top it is only adding 1.5% to whatever is in my fuel map. Not too shabby...

8 psi, I am going to get an EBC pretty soon...maybe. I am only at 82-83% duty cycle on the injectors at full load near redline. So, I think I can squeeze in 10 psi, no problem. Plus it should help with spool-up. I have the WG line going straight to the compressor housing. Before, I had it going to a vacuum block with the F/IC, BOV, and boost gauge, coming off the manifold line. The problem I was having was that, when in vacuum, the WG had some liquid water from the combustion, when cold out, and that was pulled into the F/IC lines. I knew right away what it was, that is why I went back to the compressor housing. Sorry for the explanation, I don't know why I go off on these tangents!

Yep! I figured it would definitely save cash by shortening the amount of time on the dyno. I know it probably isn't exact, but it shows gains/loss, and isn't that what dynos are for?
Not all are the same anyway, but this actually is a great tool to diagnose some problems as well, say if your clutch is slipping. It would show that by a sudden BIG increase in TQ/HP... But it is close to the same numbers being put out by Dezod's kit w/Dezod exhaust, and a 54 trim. All in all cool stuff.

hmm when i put all my inputs and i put weight to 3150 , which is me and gas....then it gave me some rpetty high numbers..i think it was near 330-340 hp and tq, so i lowered the weight to 2900 and it gave me 316/312 those numbers i was more believing, seeing as on ptunings LOW READING dyno i made 273/280
