paulr33 Posted June 13, 2014 Report Share Posted June 13, 2014 Hi All, Got my new car, Evo 8 running V44 plugin and I've noticed in the logs there is no knock #s or speed values? I would have thought being a plugin model this would work off the bat? or is it not enabled in my tune or something? Attached is the tune file. Also need to work out some of my start issues, sometimes cold start is 2500rpm+++ idle and other times hot start, starts and will then stall if I dont touch the throttle evo 8.pcl Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted June 13, 2014 Report Share Posted June 13, 2014 Hi, going by the EVO PNP HELP FILE page all of your Digital Inputs are setup incorrectly. The HELP FILE STATES THE FOLLOWING: DI 1 = Ignition switch DI 2 = Start signal DI 3 = I/C SPRAY switch manual DI 4 = Vehicle speed DI 5 = I/C Spray switch auto. DI 6 = A/C Request. To have Knock Control it must be turned on, but you will require a digital knock interface for the V44. Knock control is made active and setup under the KNOCK CONTROL tab under the ECU Settings tab. Your ECU is also running 4.9.1 firmware, you should update it to the current 4.9.9 firmware. Setup as i have described and see if you issues are resolved. As for your idle speed issues you will require an experienced tuner to get this correct, by all means give it a go if you feel you have an understanding on how this works, however if not leave for an expert. Regards Dave. Quote Link to comment Share on other sites More sharing options...
paulr33 Posted June 13, 2014 Author Report Share Posted June 13, 2014 thanks what is the significance of the digital inputs being wrong? the car runs pretty well and drives, aircon works etc so id be pretty cautious fiddling with the digital inputs. whats the worst that could happen if i change those DI's to what you've stated here?

Dave Kriedeman Posted June 14, 2014 Report Share Posted June 14, 2014 Hi Paul, I am only going by the help file PNP vehicle specific settings. I have just checked the other models and it appears that your digital inputs are setup as an EVO 9, I have no idea what is happening here other than your car had had an EVO 9 engine upgrade. The EVO 9 engine is the only one showing the engine to have VCT. If you start the engine with your laptop connected and hit the F12 key to bring up RUNTIME VALUES. Click on the digital inputs tab and check DI3 is changing speed wise as you drive the car. I have modified your PCL file and added DI3 SPEED to your PC LOG FILE LIST. Load this PCL file and create a new gauge on one of your page layouts, DI3 SPEED, if you want to watch the speed on your laptop. Open your log file and see if speed has logged. I made my comments based on the fact you stated the vehicle is an EVO 8 , EVO 4 to 8 have the same DI setup. Let me know how you go. PLEASE UPDATE YOUR FIRMWARE TO 4.9.9 to run this PCL FILE. Regards Dave.evo 8 with DI 3 SPEED added to logging.pcl Quote Link to comment Share on other sites More sharing options...
paulr33 Posted June 14, 2014 Author Report Share Posted June 14, 2014 thanks, ill give it a try it is an evo 8 and the ecu is definetly installed in an evo 8 - with an evo 8 engine perhaps this ecu was pulled from a working evo 9 and the guy (or girl) who installed it simply used the old evo 9 settings Quote Link to comment Share on other sites More sharing options...
paulr33 Posted June 15, 2014 Author Report Share Posted June 15, 2014 thanks for your detailed help so far. I haven't actually changed anything yet but I have noticed in my logs that speed does show up, but the values are completely whack ie 3km/h see attached image is it just the calibration is way off or something wired?

Simon Posted June 16, 2014 Report Share Posted June 16, 2014 Some of the JDM EVO8's ran what was to become the EVO9 ECU. The main header is the way to tell the The EVO 9 is a 3 plug ECU, where as the earlier 8 uses a 4 plug. Quote Link to comment Share on other sites More sharing options...
paulr33 Posted June 26, 2014 Author Report Share Posted June 26, 2014 hi, i did some checking tonight and here's how ive found the DI's are mapped on (by pressing buttons in car etc) DI 1 - no idea DI 2 - AUTO intercooler spray button DI 3 - no idea DI 4 - AIRCON button DI 5 - START KEY DI 6 - IGNITION ON no idea what DI1 and D3 do - is it safe to change these as per your recommendations? ie upload your PCL file and update firmware?

Dave Kriedeman Posted June 26, 2014 Report Share Posted June 26, 2014 Hi Paul, can you confirm the ECU connector plug layout as per Simon's description above please. Regards Dave. Quote Link to comment Share on other sites More sharing options...

paulr33 Posted June 27, 2014 Author Report Share Posted June 27, 2014 hi all, is there a reason the vipec cant use the factory knock sensor? i would like this input data for my logs to tune the low load IGN areas, but cant do this without knock input. i am used the apexi powerfc where knock input is standard via the std knock sensors.

Dave Kriedeman Posted June 27, 2014 Report Share Posted June 27, 2014 Hi Paul, unfortunately your ECU is a v44 topboard PNP. The V88 topboard PNP to suit the EVO'S have internal Knock Control. Regards Dave. Quote Link to comment Share on other sites More sharing options...
paulr33 Posted June 27, 2014 Author Report Share Posted June 27, 2014 ok thanks, thats fine for knock control, ie backout timing, add fuel based on knock events but what about basic knock logging from the factory knock sensor? cant this be wired into one of the analogue inputs to display values in the logs? Quote Link to comment Share on other sites More sharing options...
Dave Kriedeman Posted June 27, 2014 Report Share Posted June 27, 2014 Hi Paul, That is how the external knock module works as It goes through signal conditioning etc , to supply a signal back to the ECU. the earlier V44 series don't have the onboard conditioning circuitry to achieve what you are saying, that is why an external device must be used to interface to your ECU. They added this however to the later PNP 's that have onboard knock control due to the V88 board being used. Unfortunately we can't just fit a V88 topboard to the V44 base board either. Unfortunately the answer is external device or upgrade to an i88 topboard ECU. The other beauty of upgrading to a new i88 topboard PNP is you also get dual can bus and all the fruit of an i88 standalone with less inputs and outputs. However I am not 100% sure but I think from memory they also carry 2 onboard expansion cable sockets expanding your AN volt and Digital inputs also.. Regards Dave.

paulr33 Posted June 28, 2014 Author Report Share Posted June 28, 2014 re: DI3/ speed ok did some on road testing and watching DI3 value, it's spot on, so ive got no idea why its whacko in the logs? one thing I did do however was the gear judge was set to 5spd and my car is 6spd, so ive set it to 6spd and started doing the gear calculaitons on road. does gear judge play a part in how the data is shown in the logs for speed kph??? here's what my logs currently show before I changed anything Engine Speed 2013 MAP 49 Speed -DI3 kph 3.7 DI 3 Frequency 27.2 ie my speed is 3.7kp/h - which makes no sense, at 2013rpm. its more like 27km/h - is my DI3 freq actually just KP/H ???

Dave Kriedeman Posted June 28, 2014 Report Share Posted June 28, 2014 Hi, No your speed should read speed in KM/H. Number of gears selected is definitely important. Going by the fact that your speed is working when the vehicle moves I believe your engine and ECU setup to be a JDM EVO 8. Which is listed under the Mitsubishi EVO 9 help file last column. Can you recalibrate the gears with the correct number of gears selected and see how you go. Then post your PCL FILE and your layout file also out of curiosity. Regards Dave.

paulr33 Posted July 5, 2014 Author Report Share Posted July 5, 2014 thanks for your help, updated firmware and this appears to make the speed values much more normal gear judge appears to be working and all is well, thanks again Quote Link to comment Share on other sites More sharing options...
paulr33 Posted May 10, 2015 Author Report Share Posted May 10, 2015 hi team, evo 8 with v44 topboard PNP and im still keen to get knock input working. I've found someone selling the knockblock to suit link, is this compatible with my ecu? What else is required other than this box to get working knock input? I assume a seperate knock sensor or can I use the OEM 4G63 one already on the car? Quote Link to comment Share on other sites More sharing options...
Simon Posted May 12, 2015 Report Share Posted May 12, 2015 That would do the trick nicely and you can use the stock EVO sensor too. Quote Link to comment Share on other sites More sharing options...
paulr33 Posted September 23, 2015 Author Report Share Posted September 23, 2015 hi all,sorry to dig up old thread. still keen to buy a knock interface new or 2nd hand if anyone has one for sale?? Quote Link to comment Share on other sites More sharing options...
paulr33 Posted October 1, 2015 Author Report Share Posted October 1, 2015 hi all, sorry for thread dig up. ive sourced a Link G4 digital knock interface, the one pictured above and keen to install this soon.im using Evo plugin V44 and the documentation states; Note: If you are using a V44 or a Plug-In ECU, knock control will NOT work while the DI5 pull up is turned on. The pullup must be turned off in the DI5 setup menu. If the device wired to DI5 requires a pullup then an external pullup resistor (4.7 kOhm) must be wired. If the DI5 pullup resister is turned on, then knock control will be forced off immediately.My DI5 input is set as Start Postion, and the pullup value is set to off. Is this Ok to leave as is? can I wire the Digital Knock output (digital) to any of the un-used DI's ? thanks for your help Quote Link to comment Share on other sites More sharing options...
Simon Posted October 1, 2015 Report Share Posted October 1, 2015 Yep you can leave the Di5 as is.Yes any of the unused inputs will be fine. Quote Link to comment Share on other sites More sharing options...

paulr33 Posted November 11, 2015 Author Report Share Posted November 11, 2015 Hi all,about to connect up the digital knock interface and was interested to know if the knock kit can flash the engine light for certain levels of knock? I know I can back out timing etc but wondering if there are any form of visual aids ? Quote Link to comment Share on other sites More sharing options...
