Who is running not only the scanner but the device that monitors the sensors? I tried to read all the stickies/faqs and search but nothing comes up. I know SteVtec was running one and nj something was running one.

do you mean auterra or autotap?

i heard auterra works ok but not the dynoscna feature because of the fats sampling for ecu

i have the demo on my palm IIIc and it has lots of features lots of sensors to see you can see almost everything happening on the car i'm buying it as soon as i have the money

pepboys/kragen sells the orange colored one. My mechanic has it and I played with it. It's ok... better than nothing.
Maybe send an email to technoquare, they may have something.

I am running the www.digimoto.com OBDII scanner and software. It's great, I've reset my engine check light, pulled the trouble codes out and it allows me to monitor all of the measurements the ecu takes. For example oxygen sensor, MAF sensor, coolant temp, and intake air temp to say the least. It also lets me calculate 1/4 mile runs and estimate HP. Now I dont know how that accurate it will be with those measurements because I have not tried it out yet. But when its all said and done one of the best 119.00 I've spent.

Yeah, auterra is good. Thing is we have SLOW ECUs, 16bit I think, so true time scanning is pretty bad. 5th gens have a 32 I think. Personally if I were to get one I'd get the auterra.

bruteMax

I use the Autotaop and it's alright. It would be great if I could figure out why it only gets data every 0.8s or so. I'm only monitoring rpm, speed, timing and throttle too.

SteVTEC

ah, damn search engine is jacked up.

Anyways, yeah I have an Auterra OBD-II scanner that works off of Palm OS. AutoTap is pretty good too. And yeah, the 4th gen ECU chokes and can't run any fast sampling modes. I get maybe 5-6 Hz sampling rates (1 update per second on each parameter if you're monitoring 5 or 6, or 5-6 updates per second on a single parameter if you're only monitoring one). That's more than enough for my purposes, but the dynoscan and acceleration functions won't work without fast sampling enabled, which the ECU chokes on. But oh well.

How do you guys interpret what you see?

SteVTEC

Jeff, what are you trying to do?

Vehice speed is vehicle speed. RPM you can use to calibrate your tach. Coolant temp you can use to monitor temp at the track since the guage will just stay parked in the middle even if it's horribly heat soaked. Timing is very useful since it can be all over the place depending on whether the knock sensor is working. 23-25 degrees at WOT and redline is where it "should" be, and 10-12 degrees is where it'll be if the KS is blown. I put together a 4g timing map in the FAQ too for more detail. You can monitor O2 sensors also. Higher values close to 1.0V is rich, lower values closer to 0.0V is lean. You should be running leaner most of the time (computer in closed-loop operation), but when you get on it (above 30-35% throttle or so) the ECU will go into rich open-loop mode and just dump fuel. You can see that by watching the O2 sensors. You can also see other stuff like manifold pressure, and you can see airflow rate through the MAF in lbs/min or something. Might be useful to see for comparing intakes or different filters. Can also see IAT (intake air temp). There's a zillion things you can see or do with them.

The main hurdle is knowing what's "normal" and what's not. Like if the engine is running 10-12 degrees of timing advance at WOT and redline with a blown knock sensor you might think that's normal if you didn't know that it "should" be at 23-25 degrees. But you'd also see the silent 0304 (P0325 or something) code in the "pending" code screen (B1-S1 knock control, or something like that) which will tip you off that there's a problem. I jacked my sensor with the resistor trick until I could get it fixed and verified that it was back to running full timing with the scanner also.

iTrader: (82)

Thanks Stev. Actually it's for another OBDII car I have. RX300 has a P0171 code indicating a lean bank or whatever. Wanted to be able to read/erase the code. But having some monitoring options would be very nice also. And since the wife already has a palm thingie, that might be a nice cheap option.
The complete scanners that can do simple monitoring start at $150

SteVTEC

ooooooo...nice setup

Which Palm is that? My Tungsten E won't "technically" work with my Auterra since it doesn't have the Palm universal connector, but I can still view on it. I take it that's a T3?

SteVTEC

blown MAF?

http://www.google.com/search?sourcei...&q=RX300+P0171

For just basic monitoring and diagnosis stuff the Auterra is way too expensive now ($299). When I got it it was $219 or something but liked the extra bells and whistles.

I'd recommend the Harrison kit: http://www.ghg.net/dharrison/obdscan.html

VERY cheap. $117 shipped for an ISO-9141 only protocol (imports), or $30 more gets you a universal that will work with all OBD-2 cars (GM, Ford, Chrysler, + imports, etc). The Auterra and other more expensive setups just have more bells and whistles is all. I know a few guys here have the Harrison setup and like it also.

SteVTEC

oh cool! They must have lowered the price back down then. I have the old style auterra which was 219. Then they released the dynoscan feature and a pretty new box and jacked it up to the high-200 range. I thought that was crazy considering the fact that it was just a minor tweak to the hardware (ergonomic issue) and that I could download and run the dynoscan stuff on mine for FREE. So now prices are back down to reality.

maximus_pr

you still have to buy the hotsync cable its $19.99

you can download the demo and install it on your palm or whatever compatible handheld you have i did can tell you theres a lot of sensors and info this thing shows you can wait to buy the real thing

Jeff92se

iTrader: (82)

Stev. All I see is $195. Where is the $117 price?

SteVTEC

oh, oops! I was looking at the windoze prices. My bad. :smack:

Well damn, at that price you might as well just get the Auterra. Looks like he updated the Palm software but Auterra still looks a ton better. Either that or get something else that's cheaper - Harrison used to be A LOT cheaper. Somebody else mentioned digimoto but that's either PC or pocket PC. If you have a laptop that you could use then you could just get the $117 kit from Harrison.

Hey Jeff,

I'm running the Harrison unit on my ancient Toshiba laptop. I've enjoyed it quite a bit and have run it on my fathers 04 Sienna, my buddies 02 WRX, my wife's 98 Legacy GT, a handful of friends Hondas, and about 10 Maximas. All the OBDII loggers listed in this post read the same parameters. I've notcied that many 02+ cars also have function for Air/Fuel ratios.

Here's the Harrsion unit running in my car:



The opening screen has all the sensor values and all I have to do is highlight a particular sensor and the data graph comes up. The Harrison is probably not as sexy as some of the others, but it does get the job done. For $120 shipped, it's a pretty good deal.

I bought it because there is no simple way for clearing codes on Subarus. It's $70 to get a code pulled. So after codes, this thing paid for itself. I use the logger to observe intake air temps with different intake setup, MAF voltage (shows if a particular intake works better than another), timing (looking for knock), etc. It's a great tool.

Jeff92se

Thanks. I have an old Palm M100 and the wife has a Palm. But no labtop. So that's why I'm looking at the Palm versions

Dave B

According to the Harrison site it works with the Palm OS.

Jeff92se

iTrader: (82)

But it's $195. I've also been looking at some on ebay. The Actron all in on unit is about $140-ish there. But from what I understand these types don't have the neat monitoring the PC or Palm versions have.

Its the m515. It works well but recently I'm having trouble getting it to connect. Its real fussy about the whole thing. But I'm going to be running it all with a laptop soon so... Anyone wanna buy my setup? Just kidding.

I'm running the auterra....very intiutive pda software!!! couldn't be happier with it...now if I could only get my clie working properly...

Zack342

iTrader: (89)

can the auterra be used in conjunction with a laptop? its not specified on there website can it? i really want the dyno feature

Broaner

iTrader: (10)

The dyno feature is useless even if you could get it to work. I haven't fiddled with mine much but I don't care. The numbers it spits out are just ball park and too inconclusive to help you decide if a mod is good or bad.

michaelnyden

iTrader: (15)

well, I know the g-tech pro is supposedly kinda accurate!! and the auterra one works almost the same except it detects when your car starts moving using the speed sensor from the ecu....rather than using a gyroscope...so therefore the auterra must be kinda accurate in the acceleration tests, the dyno however, I don't know...I have never personally tried it...I have only used their software for sensor data...

is there any software out there i could use with my laptop? i have had my car dynoed on a dynojet so i know how much power is getting to the wheels i figured i could compare the accuracy and work from there,

So if someone was a total noob to this stuff like me, and doesn't own either a laptop or a palm, and obviously doesn't own any of said software, what would you guys suggest. You can get an old laptop for like $200 that I'm assuming could run the necessary program. Isn't that pretty comparable in price to a palm?

After reading this thread I'm DEFINATELY going to get one of these setups, it's just a matter of what one is best for my needs.

I'll be running a turbo kit soon and the monitoring functions of these things sound awesome for that. Also I'm currently, and will for a while at least, be running an automatic ECU in my 5spd so I already have tons of erroneous codes being thrown. This sounds like it would be much more convenient for running codes than looking at the blinking lights and sifting through what codes are actual problems with my car and what codes are just being thrown because of the auto ecu.

Jeff92se

iTrader: (82)

I'm a noob also with this stuff. You can buy the handhelds for cheaper but I don't think they have as nice of sensor monitoring that we would want. ie.. suntron etc..

Jeff92se

iTrader: (82)

Anyone try burning the software disc? Are the cables available anywhere?

bruteMax

Wouldn't be of any help since you'd still need the physical connector to the obd-ii port.

Jeff92se

iTrader: (82)

Hence the 2ND part of my question. The hotsync is available. But is the obdII and adaptor readily available. If yes, then I would only need someone to burn me a cd. If not, then ebay here I come.
