Hey guys, have 3 questions...

1) When the car is ign on engine off what should the map sensor read in smanager??? I seem to be pulling -3.0 -3.1 psi when the car is off...

2) I'm not sure if this is related or not but I have timing locked down at 16 deg, idle is set at 850 using the idle screw, tps is calabrated it's all set up ok... I idle at 14.7 give or take a .1, but on the fuel map I idle in the 3-4 area instead of 1-2 its more like 3 interpooling to 4...

3) I set my MTX-L up as follows... Red wire to add a circuit in fuse box pulling from fuse 15 (cruse control), black wire to thermostat housing, Yellow wire to B6 (yes its set up right), and Brown wire to D14. And the smanager is reading off ... Offset is at -.21... and at idle they are in sync, any thing else and its off sometimes by a whole point or more... Any ideas??? in options I have the b6 input set up as follows 0v=7.35 - 5v=22.39. and under parameters>closed loop advanced I have the conversion set up the same way. Any time I'm datalogging it shows af voltage at .98 to 1.01... this is narrowband voltage... I have it set up right just don't understand why its doing this...
Any help will be appreciated...

Anyone???

I went out and did some partial throttle tuning done on the street... all is going well... however... like I said in my first post I idle between 3 and 4. And after I did 3 or 4 pulls I looked at the estimated fuel change and realize that when I'm at full throttle and 0 vac I'm in row 7-8... I should be in 9-10... I did pulls in 1-5 gears datalogging only when I'm on the gas and its like theres a straight line at 7 and cant get into those box's... Hell I even went up a huge hill down the hill nothing cant get the graph to get into anything below 3 or above 6... wth??? I started with a basemap from a dealer on this page...

1. Setup your wideband to run off the ELD input on the ecu (d10).
2. Calculate what elevation you are at and how it will effect air pressure.
3. Make sure you are running a map sensor oring on your throttle body.
4. Refer to unit measurements like mbar, kpa, or inches/psi instead of columns.
5. Tune the car in closed loop.

I think you mean tune the car in open loop...

Is your map sensor good? What map sensor do you have selected under "MAP" in smanager? Make sure your getting a good 5V and ground at the map sensor plug.

Whats your elevation?

When I hooked my wideband up to B6 it wouldn't work bc there was already voltage there. Hook it up to the ELD input like mtber said. With ign on engine off, assuming you haven't driven for awhile it should read 5.0 volts from your wideband.

I'm not familiar with smanager, is it changing rows and such due to built in corrections?

its a stock map... it is getting exactly 5.05v... it has an oring. I'm at 3334 ft of elevation. I'll try D10 and see what it does...

yungmulacrx

Yes use the eld input.. The elevation explains your map sensor readings being in column 7 instead of 9 or 10.. And im pretty sure mtber meant tune in open loop..

Heres the funny thing... my roommate just went off the stock itr map and he idles in 1-2... is there a way to adjust the rows so there's a bit more resolution then since my altitude is messing with it???
