Boosted Tuning

iTrader: (12)

Stop messing with the gear ratios and using theoretical tire diameter. Use the actual gear ratio of your tranny and use the actual tire size.

Basically My car was tuned by a local shop at 363whp, i just got my 1.3u cable in today n ran a log 2500-7500rpm 3rd gear pull (did like 3 runs) and they all came back reading 287ish whp.... Does anyone know why virtual dyno is reading the logs/runs/pulls as if the car was stock....

Are you on a straight and level road? Did you select the correct car, gear ratios, tire dimensions, etc?

Yeah and i ran the dyno multiple times on a different road n it was still around 287-297hp,

selected 3rd gear, input the occ weight, and selected my car (2006-2007 evo 9 mr) and tires n rims are stock so i left that at default

i will say i didnt get a graph for my a/f though...i thought it would log that as i had that checked in evoscan..maybe that has something to do with it?

my evoscan settings are

openport 1.3x, mitsubishi MUTIII and EFI ecu selected

here is the run, adjusting got it to 300, but still shy of the 363 when i got it tuned

Regarding not getting your A/F graph, just go into options -> columns and profiles and add the name of your AFR column into the AFR box. That tells it what column header to look for.

checked the boxes n put in a name, but the bottom graph is still blank, i guess i may have to look over my settings in evoscan

What type of dyno did the 363hp come from and what type wideband O2 sensor/gauge do you have?

Also what are your mods?

spec ops (a local shop in fayetteville, nc) ran a virtual dyno after they had fixed some issues and tuned.

and um id say stock if i had to guess, im not sure as i havent messed with or done anything to my o2 sensor,

mods are

upper intercooler piping, upgraded injectors, fuel rail, full exhaust, intake, and i think thats it, tuned on 93 gas at 26psi, when they ran it it did 363whp

You'd have to install a wideband O2 sensor and gauge to be able to log afr. I don't think your VD numbers are too far off, but maybe a bit low, from where they should be with your mods. Someone with more experience than me should be able to say. I'm surprised it's getting the peak hp that high in the rpms with stock turbo and cams.

Just noticed you have VD set to show "Dynojet" numbers, in which case I would think it's showing lower than I would expect.

Evos don't have OEM wideband o2 sensors.

what should i set it 2? and i think i have the sensor because i have a a/f ratio gauge and a boost gauge (aem i believe) mounted on my steering wheel) i guess those count as mods i just forget to mention them

Seems like most guys post numbers set to the "VD" setting as opposed to the mustang dyno setting, which reads lower on the actual dyno, and Dynojet, which reads higher on the actual dyno. For reference, I have similar mods and have about 290tq 300hp VD numbers at about the same psi.

So is evoscan actually logging afr? If so, you'd have to have a wideband O2 sensor installed, and it would be wired into the ecu, or you'd have a serial cable coming from the gauge to plug into your laptop.
