haven't really messed with my palmer performance much lately as I dropped some $$ on a good 5 hour tune/dyno session but still need to get a wideband; I plan on running just a straight AFR gauge and maybe a boost guage (for all 8psi...). I like th Palmer for it's ability to scan and clear codes most of all though; I know AutoZone does it free but it's 5 miles away..

The Rev setup looks pretty nice too

I will at some point actually put something worthwhile on here when I get the time to play with the software some more, need to get a buddy to drive my truck while I run the laptop for a couple hours

 

Besides getting a scanguageII is there a scanner out there that will monitor ATF temps? I would like to spring for the scanguage but dont have the $$$ right now and really want to monitor my ATF temps after installing my tranny cooler.

 

this is something you will have to research to find what you really want to do!!

simple google search
http://www.google.com/search?aq=f&so...q=obd2+scanner

a computer based scanner for cheaper is like this

something to read
http://www.obdii.com/scantool_selection.html

so there are soo many options and I have seen one at PEPBOYS that seemed like it would be good and cheaper than the lesser version at AUTOZONE
which had less features and a bigger price tag!!

good luck!!!

 

Thanks Baja!
That makes me feel much better. The thing is I currently don't have a laptop that runs windows so thats why I was thinking of going this route. It will allow me to use a pc laptop in the future if I get one (leaning that way), but until then I'm pretty much stuck using this one.

 

Thanks for the good info

 

You can't monitor ATF temps with ODBII, no matter what scanner you have.

 

Then what number is the SGII reporting in the ATF field?

 

Yep, with the Xguage codes you can monitor ATF temps.

The SCII is the only one I have found so far that does this. Anyone know of another? Its always nice to have a couple products to choose from before dropping $$$

 

lol, I know...I've got one. I was asking DailyD what he meant by his comment.

Majority of the time, my SGII monitors ATF temp, Coolant temp, Horsepower and mpgs. I'll cycle thru the other gauges every so often, but the ones above are my top 4. Trip gauges get used a lot too.

IMO, the SGII is crazy over priced. I was fortunate to find a SGII on craigslist for half price new. Guy only used it a handful of times and just didn't need it any more.

 

My fault, I quoted the wrong guy haha

I agree with the overpriced comment. I been searching and hunting for a used one or a groupbuy...if you find one LMK

 

I would dare to say - not a correct one.

These are not in the ODBII protocol either.

 

Instead of Daily Drive, I'm going to start calling you Debbie Downer! I'm kidding of course.

I do know there's a temp sensor on the top right on thr newer 3rd gen trannies near the bell housing (it's similar to an O2 sensor). I'm told the SGII is pulling the temp reading from here. Looks accurate to me (at least as much as it can be). I'm looking forward to seeing the difference when I install an aftermarket cooler.

mpgs are not directly pulled from the ODBII. They are being provided thru a calculation of sorts based on trip data and fuel cost.

HP...I can't explain that. It's cool as ice though.

 

I have been using a Scangauge for 4 months now and in comparison to my Autometer ATF gauge with it's sender located before the B&M 70264 (not passed through the radiator), the Scangauge is reading roughly 5-8 degrees below what my Autometer reads. So I'd say it is pretty accurate if one knows how to interpret the numbers. Nice little device if one has $160 to spare.

Rockslide, what is your ATF temp readings running the ATF through the radiator per se on an 80 degree plus day?

Just curious....

 

While it varies from device to device, usually the MAF readings provide all the data needed to infer MPG. The device assumes that the engine keeps the ratio stoic (14.7 parts air, 1 part fuel), then just based on that it knows how much gas is needed to keep it stoic. For example if MAF shows 1.5lb/min at 35mph, that means 1.5lb / 14.7 = 0.1lb per minute, or 0.735 gallons per hour to maintain 35mph. 35 multiplied by 0.735 = 25mpg. Simple as that.

That's why the MPG reading goes really high while coasting downhill. Speed is high, while the throttle is closed and no air is moving through the MAF.


ATF temperature is not part of the ODBII protocol though. There are extension to ODBII that are specific to different vehicle manufacturers, that include ATF temps and many other things, but not through ODBII. I don't even see ATF temps mentioned on the SCII website, while they do list all the other usual ODBII sources.

 

My weekly commute is roughly 80% interstate. With that said, my ATF averages around 160 plus or minus on the intersate. City driving, with as hot as it has been lately, I've seen it climb up to 180+ degs. FWIW, I'm running Amsoil Universal ATF.



I agree, typically the MAF itself does infer mpg data, but in this case, the SGII does not rely solely on these MAF readings to calculate MPGs. In order for the SGII to derive at a MPG figure, Linear Logic designed the unit to compute a combination of readings: MAF readings, user entered settings, a trade secret formula of their own (take that for what it is) and a few other sensor readings. The user settings tweak the overall calculation and give it a more accurate final conclusion. Settings such as tank size, fuel cost, engine size, trip data, wheel size, gear ratio and so on. These all add up to a total mpg figure.

ATF Temp codes for every vehicle are not listed on their site because not ever vehicle manufacturer chooses to offer ATF temp readings. I’m not sure why you say they’re not ODBII protocol, but I am told Ford and GM have designed majority, if not all, of their vehicles to report atf temps thru the ODBII port. Toyota on the other hand (and other manufacturers for that fact) started late in the game and limited which vehicles would report atf temps. Thus the reason the codes work on some vehicles and others not. However, that may have changed by now.

Oh and the HP reading is a gross HP reading at a given moment in time. It’s not the HP I’m putting to the real wheels. In short, the HP it calculates is based on a combination of fuel consumption (by taking the BTUs used/burned) and a few other engine readings.

I know the HP figure is not a literal HP reading, but I still like to use it. I also know the ATF temps may not be exact (down to 1 degree or so), but it is real close.

 

saw this thread was back from the dead last month, used the info to pick up one from hong kong: http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWAX%3AIT. took some time to get my computer to sync up, but now works well. read the code i threw and displays current data. it's basic, but not bad for 20 bucks, if you have a laptop.

 

I use a Creader V by Launch:
http://www.scantool.net/launch-creader-v.html
It will do nearly everything my $650 Perceptor Elite will do...

 

before I let this thread fade away, made some screen shots of what you see with this cheap scantool, apart from the code screen. not sure whether the truck will supply all this. just had surgery, can't drive it so pardon the lack of real time inputs:

 

I am still looking for good cheap software. I have the scan tool from AMAZON but I can't seem to get some good software without spending a fortune. I tried the Easy OBDII 2007 on my friend's Honda but it came up with a P0147 code. All it said was "Manufactuer specific" I have the Helm's manuals so I was able to look up the code. I wish it would have told me that there was an EVAP leak on my computer screen.

DOES ANYONE KNOW GOOD INEXPENSIVE SOFTWARE BESIDES EASY OBDII 2007?
