Anastasios Kazazis Posted July 30, 2019 Report Share Posted July 30, 2019 Hi All Does any one knows what values I should use on PC Link for adding the 3 Bar map sensor ( Denso or Apexi 499-X001)? Thanks Quote Link to comment Share on other sites More sharing options...

R0b Posted January 25, 2022 Report Share Posted January 25, 2022 hey bud just trying to see if that calibration worked out. thanks for the help Quote Link to comment Share on other sites More sharing options...
R0b Posted February 4, 2022 Report Share Posted February 4, 2022 So when i used that calibration and went to calibrate map sensor before starting getting a error, could someone please help with a calibration on this sensor. with stock map sensor and stock calibration it checks out ok. thank you Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 4, 2022 Report Share Posted February 4, 2022 What does the BAP and MAP read with engine off? Quote Link to comment Share on other sites More sharing options...
R0b Posted February 4, 2022 Report Share Posted February 4, 2022 thanks for the reply i can check tomorrow but that calibration to me seems wrong cause 290kpa at 5 volt would make it a 4bar map wouldnt it since has to use 1 bar for vacuum should be -100kpa@0 volts/200kpa@5volt Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 4, 2022 Report Share Posted February 4, 2022 The “A” in the acronym MAP is for Absolute. Quote Link to comment Share on other sites More sharing options...
R0b Posted February 4, 2022 Report Share Posted February 4, 2022 someone tested a apexi map sensor in the states, @0volts shows -14.5psi and @4.9v shows 28.8psi wouldnt a greddy 3 bar be similar, seen 0.5v@0kpa could i set it up similar to greddy. thank you Quote Link to comment Share on other sites More sharing options...

As I mentioned above tell us what the BAP and MAP reads with the engine off using the calibration given and that will at least give us one calibration point against a known accurate reference.

R0b Posted February 5, 2022 Report Share Posted February 5, 2022 Thank you for the advice. Key on BAP shows -99.5, Map 0 Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 5, 2022 Report Share Posted February 5, 2022 That doesn’t sound right, BAP can’t even display negative values. And if MAP is reading zero you have something set up wrong. Can you attach your tune and a short log of it sitting there with ignition on, engine off. Quote Link to comment Share on other sites More sharing options...
R0b Posted February 5, 2022 Report Share Posted February 5, 2022 i have it setup like to said 1volt@32kpa 5volt@290kpa with the stock map sensor it shows 100kpa map and 0 bap with key on Quote Link to comment Share on other sites More sharing options...

R0b Posted February 7, 2022 Report Share Posted February 7, 2022 I'm sorry about that sir this is the one I'm working with to try to start the car, trying to start it with stock map sensor/calibration. This is the tune with Apexi map sensor. I'm new to Link really appreciate all the help Mazda FD3S Rob.pclx Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 7, 2022 Report Share Posted February 7, 2022 You need to set the calibration to "Linear Cal 1" since that is what you have set up for the MAP sensor. Not Cal Table 1. Quote Link to comment Share on other sites More sharing options...
R0b Posted February 7, 2022 Report Share Posted February 7, 2022 Well that would make sense, thanks bud. Now i just have to get spark and hopefully it starts, going to try do ignition test tomorrow. Quote Link to comment Share on other sites More sharing options...
