does anybody know a program where you can have your laptop connected to the ecu and have it monitor the car in real time? like temperature, rpm,boost, fuel etc?
Yes, Conzult. Nistune will also do that. Can't monitor boost, only things that the ECU can measure with sensors or calculate.
true, it's okay i already have a display for the boost, i'm designing a brand new centre panel for my zed, i bought a little netbook and i plan on installing it in the car and use it for pretty much everything: navigation,music,video,engine monitoring,nistune when i get it etc...
running lean... okay so i just ran conzult and these are the results at idle cmps/rpm 1400 mas air/fl 1.38 throttle pos 0.48 iacv-aav/v 25% temperature 78C LEAN 02 sensor 0.33V A/F alpha 109% timing 25btdc inj pulse 2.02 ms 2.36% inj duty what can cause a lean mixture at idle?
Why is your idle so high? Need to look into that. And what do you mean by lean? Is that from the O2 sensor? It should flick back and forth, if not it's unplugged or stuffed. Also, I have bigger turbos for sale
all cars run rich at idle, what i mean is that there is a value called M/R F/C MNT and it says lean... instead it should flicker or be rich, am i correct?
No, they should run around stoich, which is 14.7AFR. Put up a screen shot of what you are talking about, I'm not that familiar with Conzult as I have used Nistune for the last 4 years.
From my notepad of fast facts Right, so the free version of Conzult should show you: These values are only valid at idle and the values are linked. The engine should be fully warmed up. >Throttle Position (good reading TPS 0.44-0.46) > Timing ( will show set at 15 Deg, best to check with timing light) > IACV-AAC/V ( ideally 15% but a little out is OK) > Mas Air Flow 1.30v (may vary slightly) > Injector Pulse (2.2 msec, for std car) > Injector Duty (.61% for standard setup as well) > Water Temp (80 Deg C-84 Deg C) > Fuel Temp (25 Deg C-35 Deg C) > A/F Alpha 109% this is an average value and only works if you have fully functional O2-sensors and ideally you want this value to be close to 100%. any value over or under 100% means the ECU has to compensate with less or extra fuel to get the mixture right. Extreme compensations (> +/- 15%) usually mean something is wrong with either air (airleaks) or fuel (injectors/fuel pressure) I believe the rich/lean is a response to the A/F readout and is a representation of the action taken to get close to expected values. >On the free version there is only one readout for the O2, it should fluctuate up and down. Timing may show 25 BTDC if the P/N position switch is OFF (may be the case for a malfunctioning neutral switch or an auto to manual conversion.)
looks like mine is all out, even though it is an auto conversion timing says 35 sometimes and have a look at the other values
