Reyco Posted September 20, 2022 Report Share Posted September 20, 2022 Hi we have a 2012 MazdaSpeed with Force GDI, everything was fine until yesterday i turn on the engine for the warm up and without warning it turned off, now my analog temperature inputs are measuring 5V with the ignition on . The car was fine, nothing had been done to it. I appreciate the help Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 21, 2022 Report Share Posted September 21, 2022 Can you attach a copy of your tune and a short PC log with just ignition on. Quote Link to comment Share on other sites More sharing options...

Thank you for answer me First of all let me tell you more. After the failure occurred, the engine did not want to start anymore with the tuning it already had, I had to modify the fuel map again because after the failure the AFR was very rich. After the failure, the problems began, such as the 5V and the high pressure pump problem, I will attach the two tunings, the before and after. Another strange thing is that the analog temperature inputs, despite the fact that they mark 5V in the run time values, do not give me an error. I am not expert with the English, somes time i use google traslate.

Adamw Posted September 22, 2022 Report Share Posted September 22, 2022 I would say the reason the fuel has become very rich is because the MAP sensor is reading wrong. It is reading 123kpa at atmosphere. BAP sensor is showing 101kpa. This means you will be getting >20% extra fuel. Im not sure what you mean by "the temp sensors mark 5V"? They appear to be reading correctly in your log and map. For the fault code 118, try setting your GDI pump error value low pressure to 200kpa, so it is less than the low pressure pump.

Is strange because i do not have BAP sensor in the car and i am sea level. Link force GDI have internal BAP sensor? Maybe not explain me good, the analoge inputs temps mark 5V as a normal analog input. I forgot to tell you that there were two times that the MAP sensor read 300 Kpa just by putting the ignition ON. Were i can see the BAP sensor? or setup or turn off for test? Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 22, 2022 Report Share Posted September 22, 2022 All link ecu's have internal BAP sensors, calibrated by us. Yours is reading correct as you say you are at sea level, so something close to 101kpa would be correct. When the engine is not running, the MAP should read exactly the same as BAP. You can see BAP in the runtimes screen or on a gauge or in a log view, just like any other parameter. Your MAP is obviously not reading correctly, you would have to be about 2000M below sea level for a BAP/MAP of 123Kpa. The temp inputs should show 5V with the sensor disconnected, this is normal.
