Map shows 122 kpa when the engine is off
#21
Yes under engine constants is reads 400, and it has been since I upgraded from the 250 that came with the MS. It also list the 400 in the configurator. I also have extra sensor on x7 listed in the Baro settings. I have not checked the Baro gauge against the Map gauge, but I will do that when I get off work this afternoon.
To answer Joe's earlier question the voltage is 1.254
The engine map was listed as 109kpa, I will check the baro sensor when I get home tonight.

per the graph Joe provided this looks accurate for the voltage. But based on the pressure here in Plano it should be closer too 101.4. is this amount of fluctuation within spec. todays baron out side was 29.96, and my car is just sitting in the garage. I can't imagine the pressure would be that different.

I started the car this morning, and I'm seeing 109 kpa at idle. I saw 114 kpa before starting the car. Both the Map Gauge and Barometer Gauge seem in sync although the Barometer Gauge fluctuates a bit.
I'm lost as to what action to take next. It seems like maybe the Map sensor could have gone bad, but I'm not 100% positive of any of this.

Any suggestions on maybe just doing a clean install. I've done it already, but I will happily do it again if that might help.
Other than the settings.ini file can I specify the settings the MS uses then verify its using those specific settings without using megatune or tuner studio.

After trying everything suggested here and the suggestions from Matt and Ben I was ready to kick the car when I thought wow the map and baro are in sync when the engine isoff what happens when I start it. Again they stayed in sync at idle, so I reved the engine, and the Map didn't move but the engine vac gauge did. I thought what about that other nipple on the map sensor, so I swapped them and all of a sudden my map dropped from atmosphere (near atmosphere) to around 50kpa. That made me wonder about the tune so I started a new tune based on the original base map, and so foar its idle is much better. I haven't driven it yet since I have to put the MS back together, go to Denton, swing by the office and then do home work. Is it ok to use the other nipple, I thought I had been using he correct one all a long, but now I wonder if I made a mistake,

If so, you should know that that board actually contains two separate MAP sensors. (Each of the two little black squares is one sensor.) One of them is the "main" MAP sensor, and the other is the sensor used for barometric pressure reading. So it sounds like you have had engine vacuum connected to the barometric pressure sensor this whole time?

You do understand correctly, however vacuum has been in the same place the whole time until I changed it today. I understand the Map Daddy has two sensors, and thats the kicker. I just changed it, today. I've had the map daddy in place since May or so. So unless someone is playing a pretty nasty joke somethings up.
TO be sure I understand you correctly, when you refer to there being two nipples on "the map sensor", I assume that what you are calling "the map sensor" is the green daughterboard which is picture standing upright from the main board in post #18 of this thread?

I understand but that's not the one I was using. I was amazed how smoothly it fit into the case I was using the other sensor the whole time and for the most part it ran well. I was able to give my buell a break and drive to the miata to work. with the exception of working on the fine all seems well. I will try and leave it this way utill it goes in for the sawp at the endorse the year.

Sorry for the threadjack, but where might one source one of the threaded vacuum nipples as seen in this photo: http://www.ntxbmx.com/lilred/4barmap4.jpg I am assuming that it is a barb on each side with a short threaded body in the middle, right? My searches thusfar have not been very effective. :(
I know I can get it as part of the MapDaddy kit, but is it offered by itself somewhere?
