Links to jcsbanks' Speed Density patches

Updates

Aug 14, 2009: Updated all the MAP sensor scalings in the second post. All have revised "max" values which will have no effect on tune. I also updated the "increment" step size. This also has no effect on tune. The OMNI 4-bar scaling has been revised very slightly and will cause slightly different values to appear in the KPA column. I have added a scaling for the OMNI 3-bar MAP sensor.


Intro

Hey Folks, I'm starting a thread to consolidate the jcsbanks speed density patch downloads and instructions into a single post.


Prerequisites

1) A JDM 3 bar MAP sensor or some other MAP sensor that has a range of at least 3 bars needs to be installed. For those who plan to run a maximum boost between 30 psi and 45 psi, the Omni 4 bar is a good choice for cars that have a MAP sensor mouting point on the intake manifold (all USDM and some JDM Evos). Instructions for installation of the JDM 3 bar MAP sensor on USDM cars is here:

https://www.evolutionm.net/forums/ec...tructions.html

2) A manifold air temp sensor needs to be installed. For JDM Evo 9s, nothing needs to be done here. For all other cars, there are two options for wiring the sensor to the ECU. One option is to install the sensor into ADC_0E input. For non-USDM ROMs (other then the JDM Evo 9), this is the preferred method because non-USDM ROMs do not use this input, and the car can be flashed back to MAF control without having to unplug the MAT pin. For USDM cars, there is also the option to use the IAT sensor input. There are pros/cons to these two options. If ADC_0E is used, the car can be flashed back and forth between MAF and SD based control (as long as the MAF is still installed), but its a little more work to setup the ROMs to handle the MAT sensor being attached to ADC_0E. If the IAT input is used, then whenever the car needs to be flashed back to MAF control, the IAT sensor wire needs to be reinstalled into the ECU plug. For those who want to use ADC_0E for USDM cars, instructions for doing the MAT sensor install and required ROM mods are here:

https://www.evolutionm.net/forums/ec...e-logging.html

3) Before applying the SD patch, you'll want to drive the car around for a few days with the MAF still installed to log load, MAP, RPM data. This will be needed to help tune the SD VE tables. I hope to add more info on this at a future date, but for now, there is some discussion of this in later posts in this tread and in the jcsbanks speed density success thread.

Here are some general notes on setting up jcsbanks' speed density patch. I will add more to it as I have time.


1) How to install the patch: There are two ways to setup up an SD ROM for your car. Option A: Copy the SD ROM patch to your existing ROM. Option B: Copy your tuned tables over to an SD patched tephra v7 ROM. At this time, the only tephra SD patched ROM available is the 96530706. I will add ones for other ROM IDs as tephra releases more v7 ROMs.

Option 1A Instructions: Copy the ECUFlash xml definitions in the included xml file to your current ECUFlash ROM.xml (e.g. 94170015.xml or 96530006.xml) file, save the file, launch ECUFlash, open the patched ROM in ECUFlash, and copy all the SD values from the included stock patched ROM in the zipped file to a *copy* of your current ROM. Upload your patched ROM (*not* the one included in the zip file) to your ECU. NOTE: The SD patch is compatible with the tephra ROMs.

Option 1B Instructions: Copy the "TephraMOD-96530706-v7t5-JCSBSD3M3.xml" file to the "C:\Program Files\OpenECU\EcuFlash\rommetadata\mitsubishi\evo" directory. Launch ECUFlash, open the "96530706-v7t5-mods_JCSBSD3M3.hex" file, and copy your tuned tables to this ROM. Don't forget to copy over your immobilizer code, or you'll be hating life after you upload the ROM. Upload the tephra SD ROM with the tuned tables to your ECU.


2) Using different MAP sensors: The xml for the SD patch comes standard with the JDM Evo 9 MAP sensor "MAP 16bit" scaling. Below are the correct SD "MAP 16bit" scalings for all the currently popular MAP sensors. If you have one of these other MAP sensors, replace the JDM Evo 9 MAP sensor scaling with the scaling for your MAP sensor. These are only for setting up the SD patch itself and have nothing to do with adapting the MAP sensor to the car itself. That is addressed in the "log boost with a JDM MAP sensor" thread.

<!-- ** JCSB SPEED DENSITY MAP sensor "calibration" scaling definitions ** -->

<!-- ** JDM Evo 9 // UDSM Evo 10 3 bar ** -->
<scaling name="MAP 16bit" units="kPa" toexpr="x/3" frexpr="x*3" format="%.1f" min="0" max="350" inc="0.3333" storagetype="uint16" endian="big"/>

<!-- ** OMNI 3 bar ** -->
<scaling name="MAP 16bit" units="kPa" toexpr="x*0.3074" frexpr="x/0.3074" format="%.1f" min="0" max="350" inc="0.3074" storagetype="uint16" endian="big"/>

<!-- ** GM 3 bar ** -->
<scaling name="MAP 16bit" units="kPa" toexpr="x*0.3014" frexpr="x/0.3014" format="%.1f" min="0" max="350" inc="0.3014" storagetype="uint16" endian="big"/>

<!-- ** AEM (Kavlico) 3.5 bar ** -->
<scaling name="MAP 16bit" units="kPa" toexpr="x*0.4213-43.1" frexpr="(x+43.1)/0.4213" format="%.1f" min="0" max="400" inc="0.4213" storagetype="uint16" endian="big"/>

<!-- ** OMNI 4 bar ** -->
<scaling name="MAP 16bit" units="kPa" toexpr="x*0.4072" frexpr="x/0.4072" format="%.1f" min="0" max="450" inc="0.4072" storagetype="uint16" endian="big"/>

<!-- ** Kavlico 5 bar ** -->
<scaling name="MAP 16bit" units="kPa" toexpr="x*0.6320-64.7" frexpr="(x+64.7)/0.6320" format="%.1f" min="0" max="550" inc="0.6320" storagetype="uint16" endian="big"/>


3) OPTIONAL SD PATCH SETTING: The SD patch can read MAT from either the fuel tank temperature ADC or the IAT ADC. The patched ROM is set to use the fuel tank temperature ADC. If you want to use the IAT ADC, find the "SD Option" entry, and change it to "0x03".


4) Initial values for the "SD MAP Sensor VE and Calibration" table: The values for the left column of the table that you copy from the example ROM are good starting points. For the right column, a good set of starting values is use the values from the left column. You'll definitely need to change the values, but at least the car will run with this initial setup.


5) Compatibility with patch to remove MAF load limit. A few months before the SD patch came out, jcsbanks came up with a trick to disable the MAF 380 load limit. The patch consists of changing one line of code to 0x0009. This patch is *not compatible* with the SD patch, so it should not be applied.


6) Drive car and adjust VE values as needed.

Mrfred and jcsbanks FTW!!!

Please note:

Stroker's and big turbo evos that pull high loads need to know it takes a lot of logging tuning to getting everything set. I hope to have mine working soon.

Thanks

Is there any drawback from doing this change over to SD? Like not working well in inclimate weather, or temperature changes? Or does it all come down to how well it is setup/tuned?

It almost sounds too good to be true.

It still has temperature compensation, should be fine. So far I've had a 40C range of inlet manifold temperatures without issue.

Mrfred, just a note on the Omni Power 4-bar.

The sensors they originally built require you to swap wires 1 and 3 in the harness connector to work properly. Omni Power said on the next batch they will likely change it to the correct wiring so verify with Omni Power if you are using their sensor on th wiring hook up.

To log Manifold Absolute Pressure with the Omni Power 4-bar use kPa=1.632679*x, for imperial units, use PSIA=0.2368*x.

so is it safe to assume then that with 90550001 all i have to do is install an IAT and MAP sensor, the mods are already done. i am having trouble finding instructions on modding that rom for MAP and IAT.
