Looks good , same member from EvolutionOz forums ?

Hi,
I have plex usdm connected via CAN in an evo 8 using vipec v44 evo 9 PNP ecu. Let us know if you need any info on the CAN or plex setup once connected.
-
Probably doesn’t help but I have vipec v44 working with CAN streams to a plex usdm 102 and a heap of outputs working already. Have you purchased the chrono already. The plex product is very flexible, end less options
Also don’t forget some of the number so out of the v44 need an offset so I think the temperature ones are off by 50deg. The VTS help file tells you the offsets. So if oil temp is 100deg the packet will say 150deg because of the -50 offset
-
This is how mine is setup on evo 8 using evo 9 PNP v44.
note , read the VTS help file on each sector before making any changes and double check / triple check everything.
I’ve got an innovate wideband which has native 1v narrow and 5v wide signal. Connect the wide 5v to your next free analog input and you’re almost done.
if you aren’t using an innovate controller then find out the calibration table or values and you can set your own calibration table.
once you have wideband input working and the displayed value in tve VTS is correct then you can look up the wideband 02 feedback modes if you want to use it. You don’t have to but it will save fuel and make the engine more efficient (less waste).
Mine is set to complete closed loop which means the vipec actively watches the wideband af/r in real time and actively reduces fuel to reach 14.7or whatever targets you dial into the “AFR target” table.
as you drive along you can actively see the vipec trimming fuel on light cruise and it will always hit 14.7 very quickly.
See this video at 2 minute mark to see the v44 actively trim fuel in real time. AFR vs AFR target
-
I’ve got 1000cc’s In my 8 but I have no idea how they are wired in. I can send screenshots of wideband an volt setup if you need help
-
If you have wideband don’t bother feeding it a narrow 1v signal , you can simply change the analog input type on the ECU to be a 5v input and feed it the range table for your wideband and it will use the full wideband range.
Then you can if you want run full closed loop or open loop. I’ve got mine setup on full closed loop from an innovate wideband and the ecu will adjust the fuel in real time to obtain 14.7 (or whatever target you set).

I have evo 9 PNP v44 on my evo 8 and the Rev # sounds the same and doesn’t have onboard map sensor, uses an external one
-
I’ve got the green link knockblock wired into v44 evolution lancer and it works well
-
There’s one on eBay currently in Jamaica. Assuming it’s not a scam of course.
-
Make sure to load latest firmware and read the firmware procedure properly , do BAP calibration and double check all the map settings after upgrade as some of my values went to 0 on the fuel map after firmware upgrade
-
That will be a v44 I think. Either way it will run everything you need. I’ve got evo 9 v44 ECU running on evo 8 MR fq340 2.3L so let us know if you need anything specific. V good ecu to have
-
I had this issue as well , it’s the GUI. Change the value then hit enter on the keyboard to save it. Then close the window and do a store
-
Try just 1 channel at a time and get that working then try all channels. I.e just do one of the water temps and see what the value is. From memory the v44 has a temp offset of -50 so any value in the CAN packet is offset by 50deg. Can you do “math channels” on your dash to -50 from the value ?

Got the car back and very happy with the setup now. I went from Eboost2 to using the onboard vipec boost control but re-used the turbosmart boost solenoid. I did all the initial settings including setting the targets and setting all the baseline values then provided a brief outline of the setup for the workshop so they knew the basic car setup and had info on what i had pre-tuned. They then did the tune on the dyno and adjusted the values I dialed in to suit the car. I did the guess work then they've adjusted based on what the car needed. This saved a complete "tune" of the tune and a more focused tune adjustment of the boost control.
The setup looks like it has made more power but its shifted the power band considerably which I would suggest is due to the better setup and adjustment of the solenoid compared to the eboost2 fixed duty cycle (one value for all points).
Haven't driven it hard on the street yet but the dyno sheet certainly shows a very strong and responsive setup.
Just wanted to say thanks for all the help with the boost control setup
-
car is at the tuners workshop getting done, moving from turbosmart eboost2 to onboard boost control from the vipec v44. keen to see how it goes and how the boost control compares
-
Where in AU are you? My evo 8 is similar and I found on my setup the idle RPM lockout is what causes this. I’ll see what my tune looks like tonight and post up
-
I used a base project called CAN_recieve and simply modified it to talk to the 4d Display systems screen library and process all the values from my Vipec V44 on Evo 8 setup.
The project is known as mcp_can or CAN_Recieve. I found it in google last time and simply used the free library code to get started.
-
I’ve been using the plex usdm102 for a while now. Do you want the arduino code that I used ? It will only suit and work on the 3D systems display that I had
-
thanks all good, I've read the documentation a few times but misunderstood it a little, all good, will have a practice on the weekend, i should be able to pre-set it all up for my tuner and then they can adjust as needed on the dyno
-
Car going to tuners soon to setup onboard boost control using the turbo smart Eboost solenoid. Will do initial open loop setup then switch to closed loop. 18psi spring with HKS 7460 on evo 8, 2.3L.
Reasonable to set the open loop to say 20psi then when that is stable do closed loop and target 26psi? Is the difference between initial open and final closed an issue?
-
I’ve got oil temp , air temp, oil pressure , wideband and EGT inputs but no motorsport features only launch control
-
I don’t see why the v44 won’t do proper flex fuel. It’s just using the ethanol % as an input and doing a 3D map based on that or other corrections. Someone else could chime in but I’m sure it would work and it sure it’s been done on v44. I’ve got a v44 on 8 MR FQ and keen to see how you with flex setup
-
Have you tried changing the pre fuel mode from pre crank to key-on? I had to do this on my 2.3L evo. If you set the method to key-on the ECU pumps in fuel when you key-on (not start) and gives the system enough time to prime and get ready. Then after 2 seconds at key-on, turn key to start and it should start first shot
Vipec evo 9 plugin, V44 or V88 or iseries?
in ViPEC V Series

You can get the vipec input expansion adapter and it will give you a few more inputs, I think from memory two more analogue inputs and a temp input
