Elia Posted August 19, 2019 Report Share Posted August 19, 2019 Hi, Thanks in advance I have a problem, the engine start run but after few minute stop I turn off all extra output and input of Vi-PEC TT ecu but no changes thanks tt01.pclr Log tt01.llg Quote Link to comment Share on other sites More sharing options...
Simon Posted August 19, 2019 Report Share Posted August 19, 2019 Your engine temp is going unstable for some reason and is reading as low as -40 in some places and is then causing the RPM limit to go to 1000rpm and the fueling will also be upset. I would check the connections to and from the water temp sensor and the sensor its self. Quote Link to comment Share on other sites More sharing options...
Elia Posted August 20, 2019 Author Report Share Posted August 20, 2019 Hi, thanks, today i checked the wiring and it looks ok tomorrow I try to change the sensors (coolant sensor and air temperature sensor) I also found another problem I wanted to connect a solid state relay to aux ign5 but the aux does not work may be a related problem? thank you so much Quote Link to comment Share on other sites More sharing options...
Simon Posted August 20, 2019 Report Share Posted August 20, 2019 Internally there is a 0R resistor that needs to be placed for the Ign 5 output to be available Quote Link to comment Share on other sites More sharing options...
Elia Posted August 22, 2019 Author Report Share Posted August 22, 2019 hi, thanks today I changed both sensors (IAT-ECT) but unfortunately nothing has changed test2.pclr Quote Link to comment Share on other sites More sharing options...
Simon Posted August 22, 2019 Report Share Posted August 22, 2019 That's a good capture as it shows the 5V out dropping to ground. Can you take the unit out and then power on the bench with just power and ground and see if you have the same 5V issue. Quote Link to comment Share on other sites More sharing options...
Elia Posted August 23, 2019 Author Report Share Posted August 23, 2019 Hi, thanks, I power on the ecu only with pin 3 (+ 12v) and pins 1-2 (Gnd) without connecting anything else and 5V seems stable Quote Link to comment Share on other sites More sharing options...
Elia Posted August 24, 2019 Author Report Share Posted August 24, 2019 I power on the ecu with all wiring connected and only the engine off and the 5v seems ok the problem comes up with the engine running Quote Link to comment Share on other sites More sharing options...
Simon Posted August 25, 2019 Report Share Posted August 25, 2019 Next will be to unplug any additional sensors using the 5V and see if still an issue Quote Link to comment Share on other sites More sharing options...
Elia Posted August 27, 2019 Author Report Share Posted August 27, 2019 Hi, Thank you for your help I only powered the trigger sensors and the engine runs well, no 5V issue Tomorrow I check the remaining wiring and sensors Can I send you the ECU to enable aux IGN 5? Thanks Quote Link to comment Share on other sites More sharing options...
