ant.likko Posted February 15, 2016 Report Share Posted February 15, 2016 Hello,I have Evo 9 with Vipec Evo 9 V44 PnP and Vipec Knock Amplifier Kit.My questions:1. Which wire (VX ECU Digital Input or ECU Analogue Channel or Gauge Input) from Knock Amplifier I should to connect to Vipec ECU?2. Which input I should use in Vipec ECU for a knock signal from Knock Amplifier? In manual http://www.vi-pec.com/techdata/vipec-evo9-plugin.pdf speaks of Knock 1 (91 pin).3. Should I use value C for Frequency Configuration for standard Evo 9 knock sensor? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Scott Posted February 15, 2016 Report Share Posted February 15, 2016 (edited) You are going to need to sacrifice a Digital Input channel and an Aux Output/Aux Output - Fuel/Aux Output - Ign channel.Here is the list of what you have available. The red lines are because you have the V44 top-board and not the V88 top-board. If it was me I would probably move the Aux Inj 5 output (A/C fan) so that it comes on at the same time as the engine fan. You would need to change Aux 1 to 'AirCon Fan'. For a DI I would sacrifice DI 3 if you are not using vehicle speed for launch control. The knock sensor gets wired to the Knock amplifier kit, so you don't (and can't) use the Knock 1 input. The information I ahve says that your knock sensor should be a 13 kHz narrowband type sensor, which would use frequency setting C.

ant.likko Posted February 15, 2016 Author Report Share Posted February 15, 2016 Thank you very much!It's rally car. I'll use DI4 (A/C Request) for VX ECU Digital Input. Quote Link to comment Share on other sites More sharing options...
ant.likko Posted February 15, 2016 Author Report Share Posted February 15, 2016 Scott, can I use expansion cable in V44 top-board? All inputs will work? Page 11 in http://www.vi-pec.com/techdata/vipec-evo9-plugin.pdf I can't find distinction V44 and V88 in Evo 9 plugin manual Thanks! Quote Link to comment Share on other sites More sharing options...
Scott Posted February 16, 2016 Report Share Posted February 16, 2016 You can use an expansion cable, but you will only have access to what the i44 top-board has the resources for. For example, the expansion connector has DI 9 and DI 10, but as the i44 top-board only has 6 Digital Input channels, they will not work.Which version is the bottom board of your ECU? It should be printed on it, Quote Link to comment Share on other sites More sharing options...

Scott Posted February 17, 2016 Report Share Posted February 17, 2016 It is as I expected. The solution for you is going to be sacrificing one output and one input as mentioned above. Quote Link to comment Share on other sites More sharing options...
ant.likko Posted March 1, 2016 Author Report Share Posted March 1, 2016 Scott, thank you!Now I have the following problem. Knock Level Cyl 1 and Knock Level Cyl 4 all the time the same. Knock Level Cyl 2 and Knock Level Cyl 3 all the time the same too. Screenshot in attachment.And knock trim only applies to Knock Ign Trim Cyl 1 and Knock Ign Trim Cyl 3.Where could I make a mistake?Vi-PEC's Digital Knock Amplifier settings: Frequency switch is C, Gain switch is 2. Is it correct settings?Thank you for all your time and effort. Quote Link to comment Share on other sites More sharing options...
Scott Posted March 2, 2016 Report Share Posted March 2, 2016 This is happening because of your ignition setup. The EVO 9 runs wasted spark coils, and as the knock control works by retarding the ignition timing, it has to work on the pairs of cylinders.

ant.likko Posted March 3, 2016 Author Report Share Posted March 3, 2016 (edited) Thank you for your answer.Will be correction applied for Cyl 1 and Cyl 4 from table Knock Ign Trim Cyl 1? Or only for Cyl 1?-----Sorry, bad question.I should use same Knock Ign Trim Cyl table for pairs of cylinders in Cyl Allocation.

Scott Posted March 7, 2016 Report Share Posted March 7, 2016 I should use same Knock Ign Trim Cyl table for pairs of cylinders in Cyl Allocation.That will work well. Quote Link to comment Share on other sites More sharing options...
