I searched and found nothing relevant. I am heavily debating the idea that my map sensor is shot and am in denial. Everytime I have issues with the car it ends up being the map sensor being faulty. I simply have unplugged it in the past, wiggled wires and everything has been ok. More and more recently this issue has been occuring. The map sensor always reads 27 % engine load sitting without the motor running. As this type of load my car is putting in just over 3x the cranking and 4x the idling fuel input. Hence, my car floods out before it even has the chance to start... Is there anyway to use the AEM unit to recalibrate and read that resistance output of 27 as being 0 and up from there? Ive been unable to recalibrate this way and have just been able to continually select the sensor input type only.. Its a gm 3 bar map sensor. I also noticed my coolant temp sensor was reading -40 tonight when i was battling the prelude. I would appreciate any input from the tuners and experienced with AEM..

 

Just get another map sensor - doesn't the motorola cost about 30-40 bucks? if that? I say just get one and go from there.

I don't know much about the AEM unit, but with hondata - you have to select your parameters. Make sure you have the correct map sensor selected.

 

i think something is wrong with that sensor....there is no reason for it to do that....and its never good to ghetto rig stuff to work....

your temp sensor is probably gone, unless the wires are messed with...

Well, I intend to replace it with another one of the same type when and if I do... Thats just a good way to simplify wiring changes and ensure tuning isnt going to have to start from broke as the motor has about 11 hours of tuning and needs a few more...

The AEM unit is a smarter unit than the hondata.. It actually identifies my map sensor to a specific few and reads form there.. I was running through the programming last night and noticed I could modify the parameters as well... I can input a minimum voltage.. I am going to fiddle with that this weekend once I get free time again and see whan happens then.. I also intend to replace it if thats the needed case... I was hoping to hear from precision or someone like that... but I appreciate the input and would like even more...
