Where did you tap in the MAP sensor?

you can probably take fuel out if the low load idle area and clean that up.

iat is in my plenum right past the tb, and i have tried pulling fuel i guess i'll pull more.

IAT = temperature sensor

MAP is the Manifold Absolute Pressure sensor. Where is the MAP sensor connected?

o sorry misudnerstood, the map sensor is on my firewall and i have the vac line running from off the plenum by the tb, and then it connects into where the mas would plug into

Okay, after new spark plugs, my car runs fine. I think maybe even a little better than it did before. I'm almost sad to go changing it with this maftpro. Oh well. I'm ready to go whenever I get some direction. I noticed earlier that bob offered to call someone to give him help. I'll PM you my phone number if you will help me.

edit: I'm going into the city tonight. I won't be able to do anything until later tonight.

BTW I noticed that my MT is reading 90 - 100 degrees when the car is off and cold. what is that?

Where are you getting the pressure signal? I just want to be sure its not the signal to the fuel pressure regulator. That is a good signal, but the fuel pressure solenoid may mess with it.....

I am connected in with my BOV, which works fine.

ok found my problem. my pipe that goes to the throttle body from the fmic was mysteriously not connected.

fixed that and boosts great. now i just need to get my nexus to i can see what in the hell i'm doin.

question though.
when i go wot there are a few spots that it kinda stops pullin for a sec and then takes back to pulling.

somewhere around 4k

any idea what that might be?
my wideband stays on the rich side the whole time so i dont know if i need to pull some fuel or not

Its amazing how well the car will drive with the pipes disconnected (Speed Density has advantages.....)

Without a logger or boost gauge it is somewhat guess work. Do you have a laptop you can log the Pro with? There is a ton of data there.
