Peter Giljevic Posted January 22, 2010 Report Share Posted January 22, 2010 My other thread vanished? My Link G4 plug in 3 times now has cut out at 3000rpm after 20 to 30 minutes driving in high ambient weather conditions (35deg C+). It will not allow the engine to exceed 3000rpm until the ECU cools down. This is not random in nature and is totally repeatable every time the ambient weather is high! and the ECU case decides to limit my motor. I sent Link a log and their engineer tells me its a trigger set up problem? funny it never happens at cooler ECU temps and all wiring is perfect and never had any issue with Apexi PFC. Opinions? Others experiences? Quote Link to comment Share on other sites More sharing options...
Peter Giljevic Posted January 22, 2010 Author Report Share Posted January 22, 2010 Can ANYBODY with a FD3S RX7 please send me your Trigger arming threshold values for the G and Ne sensors please. I want to cross check the averages people have measured and set V's what I am going to test mine at. I have one of a ViPEC customer car and it is vastly different to what Link List in the default maps for the FD3S files they provide with the ECU. Thanks. This is the last thing I have to check/tweak, if this does not work then a 4 pound hammer will be the next resort ! Quote Link to comment Share on other sites More sharing options...
martin battye Posted January 22, 2010 Report Share Posted January 22, 2010 Peter i just checked your logs... your TPS trace is dissappearing.... hence you are getting decel fuel cut.?? Quote Link to comment Share on other sites More sharing options...
Peter Giljevic Posted January 22, 2010 Author Report Share Posted January 22, 2010 No you need version 4.4.6 to view them as I run special software. The only parts you need to look at is right at the beginning and under constant TPS acceleration as soon as the engine approaches 3000rpm (every time consistently) the fuel injection pulse will drop out as will the RPM. This is not random and it happens every time the ambient weather is 35+deg C and the ECU is showing about 64deg C internal temp. I need to STRESS, this ONLY happens when the ECU heats up!!!!! very consistent and very repeatable, it does not happen in the first 20 minutes of running the engine nor does it happen in cooler ambient weather conditions (ECU showing lower than 50 deg C operating temp) thus is CANNOT be anything to do with wiring nor trigger settings, as that makes no sense as the inductive pickups voltage outputs do not vary with temperature, and I would have this problem ALL THE TIME regardless of high ambient temperature and thus ECU case temperature after a period of time running in it..... I have run this engine and ECU for over 2000km (fully tuned to 8000rpm and 1.1 bar boost) and I know how it works and when it is faulty. If only someone would listen to me Quote Link to comment Share on other sites More sharing options...
martin battye Posted January 23, 2010 Report Share Posted January 23, 2010 yes.. i have viewed the whole log in my log viewer.. there is one point towards the end that clearly shows rpm increase with the TPS staying at 0%. the throttle is clearly open by the fact that the MAP is not at an overrun value. so it cannot be you downshifting.. this is perhaps even a separate problem. . im away from home atm. once i return i will take a more indepth look. for now can you take another couple of logs.. really need to definately prove you dont have a hardware breakdown.

Peter Giljevic Posted January 23, 2010 Author Report Share Posted January 23, 2010 Going down big hill and put it into a lower gear so I could show it shitting itself in the logs on deceleration. I don't need to log this cunt anymore or waste another minute of my life on the piece of garbage. Link can send me a new ECU or I can just tell everyone how many fucking hassels I have had with it and how much money and time from my life it has taken away from me due to one shitty electronic box. I am not some dickhead, I do this as a job, I don't see why the onus should be on me to prove beyond doubt that its faulty, I have already gone through this once before and wont be doing it anymore. No cunt has explained to me why this happens with temperature yet? all I get is excuses and a big fuck up run around and it shits me to death, never had to go through this level of crap before with anyone.

Guest Dave Posted January 23, 2010 Report Share Posted January 23, 2010 HI Peter one reason why no dealer has jumped in here to say why ity cuts out at temperature is the fact we have never seen it happen and I personally have tuned hundreds of these ecus ranging from pluggins to the wire ins and yes they are also on race cars and yes they are in countries with high temps the one i do in Barbados would be a good example , no issues there that i have experinced.. I am not saying you dont have a fault just never seen that happen before. using the laungauge that you have in the last few posts wont help either and do you expect an immediate answer from a forum on a weekend? Send me a log and i will see if there is anything obvious especially one with markers where it is aparently cutting out ..

Peter Giljevic Posted January 24, 2010 Author Report Share Posted January 24, 2010 E-mail sent, excuse my language, just very frustrated and I have been ultra diplomatic and care free with my time/money to this point....... I have just run out of all reserves of tolerance & need this fixed. Quote Link to comment Share on other sites More sharing options...
Guest Dave Posted January 24, 2010 Report Share Posted January 24, 2010 Email received will look into it Regards Dave [email protected] Quote Link to comment Share on other sites More sharing options...
martin battye Posted January 25, 2010 Report Share Posted January 25, 2010 is there anything in the ecu that can cause the rpm trace to return to 0 other than a faulty trigger? Quote Link to comment Share on other sites More sharing options...
