Bowie69 Posted November 12, 2013 Share Posted November 12, 2013 I always thought it was ground the wire to switch... but I suppose it will differ depending on who and how it was built. Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 12, 2013 Author Share Posted November 12, 2013 this is one of Nige's ECU, maybe he will come by and clarify this point but if i should ahve ground it.... putting 12v on it probably fried something, right? Quote Link to comment Share on other sites More sharing options...
elbekko Posted November 12, 2013 Share Posted November 12, 2013 Applying 12V to it seems dangerous, unless there's a voltage regulator on the line... Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted November 12, 2013 Share Posted November 12, 2013 Not likely, the circuits are very well protected on the V3 board, high impedance input = no current = no bang/smoke. Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 13, 2013 Author Share Posted November 13, 2013 just tried ground it and still the same result... nothing happens. i'm starting to be disapointed. one of the advantages of having this system was to change fuel and spark tables on the fly. if i have to walk around with a laptop every time i want to use the RR it's a bit of a F****** job..... anyone knows if Nige has been around? if someone "talks" to him could you tell him to come by this topic. thanks Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 13, 2013 Share Posted November 13, 2013 Your being a Nige one it should be +12v on the pin to switch, you should see the NOS/TABLES input indicator in MegaTune change colour, I don't know what TunerStudio has to indicate this (if anything). Nige's have a signal conditioning circuit on the input, frankly anyone wiring direct to the pin of the CPU is asking for trouble - and I do know that some "professional" builders out there do this (and other nasties). Bowie - the standard V3 boards are protected, but only on the standard circuits, extra inputs are wired by the ECU builder and may or may not be done nicely.

csimoes Posted November 13, 2013 Author Share Posted November 13, 2013 Fridge i'm complet ignorant about electronics. this is a pic of my board (posted in another topic) can you tell what was done? when you say connect directly to the ecu pin, what i'm doing is connecting the 12v signal that cames from LPG to the spr1 on the realy board. isn't this the correct way?

As FF has said +12 to switch tables as below...... Also in TS the NOS/TABLES input indicator is colored RED when there is +12v to switch table and clear when not powered.

csimoes Posted November 13, 2013 Author Share Posted November 13, 2013 ok just tested the db37 cable with a multimeter and it's ok. so lack of comunication it isn't. when going home i'll connect the laptop and report back about the NOS/TABLE signal Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 13, 2013 Share Posted November 13, 2013 This changes colour when the input is active (12v on it): Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 13, 2013 Author Share Posted November 13, 2013 i'll check that and report back Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 13, 2013 Author Share Posted November 13, 2013 in the case of that option being RED then the saprk advange gauge will show the correct advance? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 13, 2013 Share Posted November 13, 2013 in the case of that option being RED then the saprk advange gauge will show the correct advance? The spark advance gauge (in MegaTune) shows the advance plus the TRIM angle, so it will always look wrong, you can correct this by changing the gauge configuration in megatune, I don't know about tunerstudio.

csimoes Posted November 13, 2013 Author Share Posted November 13, 2013 ok just got home. no red light on. neither MT ou TS showed red. but i notice something, is the FAN/OutPuT4 suposed to be green all the time? Quote Link to comment Share on other sites More sharing options...

Is that with the TS or MT connected to the ECU? Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 13, 2013 Author Share Posted November 13, 2013 MT for sure TS i'm not certain but i seem to remembre being on too Quote Link to comment Share on other sites More sharing options...
bobtail84 Posted November 13, 2013 Share Posted November 13, 2013 The 1st img is the Petrol TS dash. You can see NOS/Tables off and it's NOT coloured red. Also the spark advance reads 10.1 at idle. The 2nd img is the LPG TS dash. You can see NOS/Tables ON and coloured RED and the Spark Advance is reading 12,9 at idle because of the different spark curve for LPG.

csimoes Posted November 13, 2013 Author Share Posted November 13, 2013 that doesn´t happen on mine. and i'm allmost certain that in TS the FAN/OUTPUT 4 was green to Quote Link to comment Share on other sites More sharing options...
bobtail84 Posted November 13, 2013 Share Posted November 13, 2013 I will check but I think when Fan/Output 4 is green when the Injectors are firing. If you look at the 2 images I've posted above and the LPG dash shows Fan/Output 4 clear and green in the Petrol dash. Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 13, 2013 Author Share Posted November 13, 2013 uhmmm i think i saw it green on LPG. tomorrow i'll confirm that, on what situation it is happening Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 14, 2013 Author Share Posted November 14, 2013 good Morning well first thing - the green light i saw with FAN, was FAN/injection, so that is normal , FAN/OUTPUT4 never came on - NOS/TAble never came RED on any situation even disconnected the signal wire from the LPG with the car running and all was quiet. no changes. - if it is something setup wrong in TS or MS, witch i don't think so, heres my .msq. if you could look at it and see if theres something wrong please let me know. i'm only spark switching. (allready did spark and fuel table switching at the same time and the result is the same) 2013-11-14_09.36.59.msq Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 14, 2013 Share Posted November 14, 2013 So are you putting +12v on the SPR1 pin? Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 14, 2013 Author Share Posted November 14, 2013 Fridge, yes. 12v when LPG goes on Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 14, 2013 Author Share Posted November 14, 2013 is there some way to test if the 12v getting to the relay board really get to exit on pin 3 of the relay board male db37? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 14, 2013 Share Posted November 14, 2013 Edit - Ah, relay board! I'm pretty sure they require modification to pass the signal through. Double edit: A basic continuity test (buzz) with a multimeter would confirm it. Quote Link to comment Share on other sites More sharing options...
