neil brown Posted May 28, 2019 Report Share Posted May 28, 2019 My car is a Subaru Impreza ver 4 and according to your software pull-up resistor is OFF active edge is FALLING calibration di2 is 260 are these aettings ok to use on g4 storm wire in spwed sensor input comes from speed sensor on gearbox Quote Link to comment Share on other sites More sharing options...
Simon Posted May 28, 2019 Report Share Posted May 28, 2019 Yes that would be fine to cross over to the Storm Quote Link to comment Share on other sites More sharing options...
neil brown Posted May 29, 2019 Author Report Share Posted May 29, 2019 Simon can i use any of the DI inputs 1-4 for speed input or limited to select few ? Quote Link to comment Share on other sites More sharing options...
Simon Posted May 29, 2019 Report Share Posted May 29, 2019 Any are fine Quote Link to comment Share on other sites More sharing options...
neil brown Posted May 30, 2019 Author Report Share Posted May 30, 2019 Thanks Simon will get it wired up Quote Link to comment Share on other sites More sharing options...
neil brown Posted May 30, 2019 Author Report Share Posted May 30, 2019 Wired up to DI4 and enabled it as per settings no speed input showing on laptop tried rising and failing settings but nothing checked the Subaru wiring states it goes from 0v to 5v in square wave go as my speed sensor is a magnet based sensor 2 wire type not a hall sensor is there any other way I can get speed to work Quote Link to comment Share on other sites More sharing options...

Simon Posted May 30, 2019 Report Share Posted May 30, 2019 In a normal set up the speed is sent to the dash and then back to the ECU the dash sends a 0-5 square wave to the ECU. If you have the sensor wired direct to the ECU you will have one wire to the Di and the other will be to a sensor ground. Being a VR sensor you might need a bit of speed up before the ECU picks up as the voltage will need to reach greater than 1.5Vs before the ECU will see it.

neil brown Posted May 31, 2019 Author Report Share Posted May 31, 2019 Must be missing a ground somewhere Will check new speed sensor on output Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 31, 2019 Report Share Posted May 31, 2019 A V4 should have a hall effect sensor according to our manual. Quote Link to comment Share on other sites More sharing options...
neil brown Posted May 31, 2019 Author Report Share Posted May 31, 2019 a united kingdom k ver4 has a reluctor sensor as got spare sitting in kitchen for the 6 speed conversion it has 2 wires on a plug and according to wiring diagram goes straight to the speedo head, but on the ecu pin out on middle plug wire 3 says speed signal either 0 or 5v alternating as convertor inside speedo head to drop it to 0-5v alternating signal read on another site that the ver4 reluctor speed sensor will do 20v ac when up to speed, as spinning by hand i get 4v ac on plug and go to frequency i get 16 hertz is it possible to piggy back the reluctor cabling at gearbox and use it for ecu input on DI4 and still maintain speedo function, does the ecu not take any load from a gearbox sensor Quote Link to comment Share on other sites More sharing options...

neil brown Posted June 3, 2019 Author Report Share Posted June 3, 2019 Simon or Adam w what you think is is it possible to pudgy back original 2 wire sendor Quote Link to comment Share on other sites More sharing options...
neil brown Posted June 5, 2019 Author Report Share Posted June 5, 2019 Simon or adamw can you advise on above if it’s possible Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 5, 2019 Report Share Posted June 5, 2019 Either reluctor or hall is fine. Hall is generally better for speed as they work right down to zero. If you are getting no signal then either the sensor is dead or you have the wiring wrong. Quote Link to comment Share on other sites More sharing options...
neil brown Posted June 5, 2019 Author Report Share Posted June 5, 2019 Speedo works fine no issues with that will try to wire it direct and see what happens Quote Link to comment Share on other sites More sharing options...
neil brown Posted June 5, 2019 Author Report Share Posted June 5, 2019 Connect directly to ecu using di4 and do I use sensor ground for other wire as 2 wire speed sensor will the cam and crank signals not be affected if I tie in to sensor ground Quote Link to comment Share on other sites More sharing options...
Simon Posted June 6, 2019 Report Share Posted June 6, 2019 I wouldn't expect the ground to be needed as the dash would normally be grounding it. Just check to see if you have continuity to the block on one of the wires, You should then tee off the other to the Di Quote Link to comment Share on other sites More sharing options...
neil brown Posted June 7, 2019 Author Report Share Posted June 7, 2019 Simon or adamw hete is a ver 4 U.K. Impreza wiring for speedo circuit and see it’s a wire sensor which has a spinning magnet inside of it is it possible to picky back it to ecu so I use di4 and sensor ground ?
