Alright, I got a good one for you techies out there:

Some of us (inluding myself) don't really know ALL of the different parameters of Scan Mode (ie, their significance....normal numbers while at idle & WOT).

It would be nice to have a list with all the information of the parameters and their usual results (ie. numbers)

...if someone with enough knowledge has the time to sread the info.

Thanks!

 

this would be a great list, but keep in mind a lot of the parameters will vary depending on the setup of each car... such as CAI, smaller pulley, 2.2 vs SC, etc

 

if ur not the tuner of ur car all u need to watch is ur knock retard (knock should be very min and none at wot) and ur IAT2 temps..if they get to high stop killing ur car..

 

Forgive me for any errors, just wrote this up quick. correct me if you see any.


RPM - Obvious

MPH - Obvious

Intake Air Temperature pre intercooler - Intake temperature (IAT1) usually slightly above ambient at operating temps

Intake Air Temperature post Intercooler * - Intake temperature after blower (IAT2) important parameter for ss/scs, shows how much heat your blower is making. usually about 20* above IAT1 during normal cruising

Mass Air Flow Sensor Frequency * - The signal sent from your MAF to the PCM telling it how much air is flowing by the MAF. anywhere from 0 to about 12000hz

Mass Air Flow Sensor (lb/min.) - Measurement of air/minute passing by the MAF sensor.

Engine Coolant Temperature - Obvious. Usually runs at about 180*F (80*C)

Injector Pulse Width - amount of time (in ms) that your injector stays open during each fuel delivery cycle

Long Term Fuel Trim - an indication of how much fuel the computer is adding/subtracting to keep the car at the stoich 14.7 AFR. you want it somewhere between -4 and +4. zero would be ideal

Short Term Fuel Trim - similar to LTFT, but where LTFT is a slow average, STFT is the short term immediate changes the computer is making to maintain stoich. once again as close to zero as possible.

O2 Sensor Voltage - Signal being sent from your O2 sensor to the computer. I believe its narrowband, so the signal should be between 0 and 1v. (someone correct me if im wrong on that one)

Manifold Pressure in PSI (Boost pressure) - Obvious

Supercharger Inlet Pressure * - Obvious

Ignition Advance - this is your "timing". during cruising youll see this up in the 35+ range, during WOT, you will see it build, usually from the high teens, up into the low 20s

Knock Retard * - The amount of timing the computer has pulled after detecting knock. you want this at 0

Engine Run Time - obvious

Battery Voltage - obvious should be in the 14s when running, you will need about 10.5 at least to start the car.

Throttle Position Percentage - obvious, though flawed. at 100% throttle, this will only display 88%. this can be fixed in HPtuners.

Engine Load - pretty straight forward. how hard the engine is working.

Instantaneous fuel economy - a calculation of what your fuel econemy is on a very short term basis.

Horsepower - a calculated estimate of your crank HP. not really very accurate, but handy for seeing CHANGES in hp after a mod.

Analog input #1 - 0-5v analog inputs

Analog input #2 - 0-5v analog inputs.

 

wow an0m...wow...good quick input

 

can i also add that if you own a 2.2l that your a retard for not buying a dashhawk over a interceptor.

 

Just wondering, why do you say that? What advantages are there over the interceptor? Just wondering since I am gonna buy one of these soon......ReignSS also told me to get the dash hawk though.

 

true, and i did think about that when i was beginning my original post...i just thought i`d throw it out there to see what comes back... and of course, its still nice to know the relevance of the parameters to see on the gauge itself...helps us better understand our car`s condition

an0malous...i love you lol

 

because the dashhawk just plain does more then the interceptor does. not to mention you can run you wide band o2 sensor though it by using hawk eye. it has amost 2x as many parameters that the interceptor has for the ls. not to mention you can manually overide your cooling fans so to run on full bore to avoid over heating or cooling your car down at a light while your waiting to race. you can doe case relearns where lets say you put an intake and exhaust on. it will ajust to the intake and exhaust so you dont get any cels.

here are gm specific things the dashhawks does

wow...certain features of that dash-hawk i really would enjoy...but it seems like its based more for an automatic...correct?

 

Thanks nramlow2006

 

no its base more twards everything. they really coverd there bases with this because it watches almost every aspect of your car. and lets say a problem arises you can data log then connect it to you computer and read all hte possible solutions to your problem. not to mention it will tell you what your code is vs giving you the code. something that the interceptor doesnt do.

no problem

 

Why should you only get the dash hawk if you have an ls?

 

subscribed

 

because its way better then the interceptor. not to mention you can only have one or the other. i use my dashhawk the most when im running nitrous.

 

Sorry, let me rephrase that. Why do you say you should get it if you have the 2.2... as opposed to a 2.0? Are there certain features that will not work on the SS/SC, or things that it can't do on the SS like read boost or something?

 

WELL msd hasnt yet supported the lsj pcm yet. that is why. i say if you a a 2.4 or a 2.2 that is the way to go. if you guys had support for the lsj then im sure almost everybody here would end up buying one. considering is a way better product

 

Oh ok, thanks for the info.

 

does the dash hawk work for the 2.0? a friend has one, and when we tried plugging it into my car it wouldn't read anything. i don't see it listed on dashhawk's site either, just the 2.2 and 2.4
