The DTC feature has never worked right for me. It doesn't read any of the codes the OBDII does, and doesn't clear them either.

 

Well, the "Fuel Consumption" readings are way out of wack. With the factory formula it never exceeds 1 litre/Kms. I'm pretty sure it should be in the 9-11litres/Kms range.

The edited formula for MPG(U.S. gallons) was reading in the 200MP range....i wish! lol

I noticed the 'notes' say to use the formula:

[RPM]*[InjPulseWidth]*20*6/[Speed]/1200

but the actual formula for MPG with U.S. gallons should is:

MPG=MPH/GPH

Fuel Consumption MPG (U.S. Gallons)= [Speed]/(513*4*[InjDutyCycle]/100*0.015873)

513 is the injector scaling size used in ECUFlash, multiplied times 4 injectors
0.015873 is the conversion from cc/min to gallons per hour

 

im having the exact same problem. tried changing a few different settings with the comports and tried uninstalling drivers for the cable and reinstalling. cant seem to get anything. it connects for a second then boots me off say com1 not found? any advise anyone?

 

I tested this on my Girls 02 WRX....the datalog speed was between 20-80 samples....SLOWWWWWWWWWWWWWW.....and the baud rate was only at 4800

Did that work for you Jack? Mine is out of whack... Says I got 315MPG under WOT in 3rd gear... I should do that more often...

 

I gotta wait til morning. If someone wants to go try it for me...that'd be cool. Best way to check it is on the highway at a smooth cruising speed. Its gonna be really erratic since it responds so quickly. I wish there was a way to slow down the response rate so its a bit more linear. Anyone know if we can do that?

At around 95% IDC (around 7-8K rpm) and in the 80mph range topping off a 3rd gear pull, you should be around 2 mpg,lol.

 

I'm guessing baud rate??

 

Got mine yesterday.....

Has anybody been able to get the map tracer to work?

When I am connected to my Evo8, I click on "graphs" and then on the first selection "Real Time Graph - Map Tracer blah blah" but nothing happens.

If u have been able to get Map Tracer to work, please post here on how u went about it.

thx

 

Map tracer won't work if you have Calculated Load and 2-Byte load logging at the same time....the software doesn't know where to draw its data from and show nothing but blanks....

 

Do you right click the bottom field and load you .XML and .HEX files in?

 

Yeah but nothing happens, which makes me think that there is other things I shoulld be doing first.

One thing I have since found out, is that my ROM : ECU ID - 96530006 is not listed in the /EcoSan v2.1/ROMS folder. I select it out of the ECUFlash Rommetadat folder. Do u think this might be part of the problem?

Also does clicking on the the min menu : Graphs - RealTime Graph _ Map Tracer link do anyting for u.
Nothing happens when I lcik on it.

The only way I can get into Map Tracer atm, is to go into Graphs - Open Log File - Map Tracer, but that is not ideal, since my understanding is that Map Tracer should be working in real time (and I can get it to work anyway).

Any help is appreciated thx.

 

I think my IDC values are 25% of where they should be. Anyone else test theirs yet?

I logged this:

RPM = 2968.75
IPW = .002816 sec. (2.816ms)
IDC= 1.783%

IDC should read 6.967%


UPDATED: Evoscan v2.1 Injector Duty Cycle formula is incorrect. Read post#60 below for the correct formula.

 

Thx that sorted out the problem...

Still new to logging an Evo, I came from a Subaru tunning/logging background using Enginuity and ECUFLash.

Now if only I can get 2 byte logging to work.... using a 9653006 ECU and it doesn't seem to be a very popular one with no support on it.

 

The IDC formula is wrong. Remove the "0.256*" from the beginning.

It should be

[InjPulseWidth]*31.25*x/1200

Fuel Consumption MPG(U.S) is:

[Speed]/(513*4*[InjDutyCycle]/100*0.015873)
