Boost Adder (PSI) : PSIa16 JDM3barMAP -> PSIa16 OMNI4barMAP.Boost Desired Engine ‘PSI’ : PSIa8 JDM3barMAP -> PSIa8 OMNI4barMAP.Boost Error Correction (PSI) : BoostErrorPsi JDM3barMAP -> BoostErrorPsi OMNI4barMAP.Alternate Boost Desired Engine ‘PSI’ : PSIa8 JDM3barMAP -> PSIa8 OMNI4barMAP.Right-click on the map/table in the left column of EcuFlash and select Edit, and pick the appropriate scaling from the drop-down menu. If you are using a different MAP sensor, you need to change the scaling on a few tables from ‘PSIa8 JDM3barMAP’ to ‘PSIa8 OMNI4barMAP’, or the preset for your specific MAP sensor. This rom has no scaling tables for the MAP sensor and is setup for the JDM/EvoX 3bar MAP sensor by default. To keep things simple, consider doing the same on your car, as SD idles amazingly well, even on a highly modified engine. I left all of the stock values, save for desired idle RPM alone. A GREAT tool for this is this translator but don’t just plug values in blindly, carefully double-check several rpm vs load cells and make sure they line up. This is a mixed blessing you now have a lot more resolution when tuning, but you’ll have to get your existing table translated into big maps. NOTE: This rom comes with BIG maps enabled. Immobilizer (or immob disable…if you car won’t fire at all, this would be why).MAP sensor scaling (scaling and xml here and here if you don’t have this running already).MAF scaling (yes this does still have an effect).High/Low Octane Fuel and Timing tables (including rpm and load scaling values).The ones that are key to getting this rom up and running on your car: The XML file that comes with these pre-patched roms does a good job detailing the periphery bits, so be careful which ones you copy over, and be careful which values you copy over in the MUT table. I say *most* because there are some things set in this new rom that you’re not going to want to mess with. Step 3: Copy *most* of the tables over from your old rom to the new rom. The XML is included in the pre-packaged rom, so simply find Fix2 or Fix3 under ‘Speed Density Programming’ and adjust the values per the mini directions. The final fix is still up in the air, but for now, I’m recommending mrfred’s fix#2 since I’ve had the best luck with it. There is a very small issue with the existing speed density implementation that causes an ever-so-slight jitter while cruising around 2000-2500rpm. Step 2a: light throttle cruise jitter (this may go away some day) Then load your existing rom off of your car or open a previously saved copy. Hit save and call it 96531706-myspecialname-test1.bin (keep the original untouched so you have a local backup copy). Open the 96531706-TephraMod-phenem-sd.bin, make sure you can see some of the tables and that all is well. Put TephraMOD-96531706-v7.xml in C:\Program Files\EcuFlash\rommetadata\mitsubishi\evo\ and rename it 96531706.xml zip file, put the 96531706-TephraMod-phenem-sd.bin file in a new folder somewhere called SpeedDensity. I used tephra v7 because it has all of the latest and greatest hacks in it, and this pre-patched rom has a LOT of work behind it to make what you’re about to do much easier! Unpack the. I used post #2, option 5, here’s the direct link: Download Step #2: Get a pre-patched rom from tephra/phenem: If you car is in disrepair, take care of maintenance items before attempting this conversion you will only be making it harder on yourself! Step #1: A good running car with a safe tune on it.ĭo a boost leak test, have a spare set of spark plugs handy (your existing ones may get fowled during this conversion process), fresh fluids, known-good boost levels, etc. See the Innovated LC-2 Eat Sleep DSM write up.Wideband O2 sensor: several are available, I use the Innovate LC-1 wired into the ecu.Uprated MAP sensor: evoX 3.3bar or Omnipower 4.0 bar.Otherwise, swap the hardware below and read on! I HIGHLY recommend getting these going on your existing rom so you have a known good rom to easily flash back to while you are getting speed density going (in case you run into trouble and simply need to drive the car). Don’t forget to thank them once you get it running properly: jcbanks, mrfred, JohnBradley, tephra, phenem, recompile, l2r99gst…to name a few.įirst off, there’s some hardware required. Make no mistake, speed density running on the stock ecu is a culmination of years worth of work by a lot of people around the world. Scheides tested, ecu-guru approved! Still, be careful.Īlso, it may (and likely will) change, I’ll try and bump the thread with ‘updated’ as I do so…this is a work in progress!Ĭonverting your evo8 to speed density is a lot easier than you might think! With the right tools, some time, and careful steps you’ll be running MAF-Free in no time! I’ll be using a lot of hyperlinks for reference points on material previously covered elsewhere.
