R33Beech Posted September 23, 2023 Report Share Posted September 23, 2023 I have an RB25DET Neo. I have tried both the stock boost sensor as well as an AEM 3.5 bar MAP sensor. Made sure each was calibrated accordingly (created the linear calibration for AEM). Both read 180kpa with key on engine on, and at idle. Once idle warms up it goes to 200kpa. I feel like they couldn’t both be faulty (they both worked previously). Is it a setting? Could it be something I didn’t correct with map calibration?

Adamw Posted September 24, 2023 Report Share Posted September 24, 2023 When you last saved that map the MAP was matching your BAP and the voltage on AN Volt 3 also matches the reported pressure. Quote Link to comment Share on other sites More sharing options...
R33Beech Posted September 24, 2023 Author Report Share Posted September 24, 2023 hmm... do you know why the table values are showing 180-200kpa when it is running and scavenging? Quote Link to comment Share on other sites More sharing options...
castillaricardo Posted September 24, 2023 Report Share Posted September 24, 2023 Your axis is set to MAP Limit, not MAP. Change it to MAP or MGP by pressing X or Right Click > Axis Setup Quote Link to comment Share on other sites More sharing options...
R33Beech Posted September 24, 2023 Author Report Share Posted September 24, 2023 ahhh shoot. I’m a noob right now with the software. Thanks! Quote Link to comment Share on other sites More sharing options...
R33Beech Posted October 16, 2023 Author Report Share Posted October 16, 2023 So the MAP sensor is seemingly only reading the barometric pressure, but it’s not reading anything at any load. While running and logging it just stays at BAP. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted October 16, 2023 Report Share Posted October 16, 2023 Is it plumbed into the intake manifold post throttle? Quote Link to comment Share on other sites More sharing options...
R33Beech Posted October 16, 2023 Author Report Share Posted October 16, 2023 Yes, I have a line going from intake manifold to vacuum block and it’s plumbed there. I can try to plumb it direct though. Quote Link to comment Share on other sites More sharing options...

R33Beech Posted October 16, 2023 Author Report Share Posted October 16, 2023 Fml. Well… I feel dumb. There’s no vacuum coming from it, must be blocked. 13 minutes ago, R33Beech said: Fml.
