Quick DH question & ATR datalogging

Quick DH question & ATR datalogging/ DH install pics added

I assume the DH plugs into the OBDII port, and I was wondering if the plugs that goes into the DH is the same as the AP, or if you have to be swapping out the dongles when you want to use the AP? I doubt they're the same, but it would be nice if they were. Also, how do you get the datalogs off the DH? Is it via a USB port/flash drive?

Also, can someone describe how to datalog with ATR instead of the AP? I tried having the dongle of the AP plugged in, and the micro-usb plugged connecting the AP to my laptop. I kept getting some error code (I forget what it said, but my AP died yesterday so I can't try it now). I don't know how you could plug the dongle directly into your laptop, unless there's some adapter?

Sorry if it's a dumb question, but when I get my AP back, I'd like to get some more accurate data logging with ATR. Plus, in the meantime I'm blind, and my fuel pressure is a bit sketchy.

Thanks guys!!!

The DH end of the OBD cable is unique to the DH, so must swap cables for AP. The DH logs are downloaded via a "standard" micro USB (for the DH) to a std USB end for the 'puter. Note the OBD cable MUST be unplugged from the DH to download/program the DH.

I've never tried to connect straight into ATR. I don't think it is possible with the "old" version AP with dongle. I've read there is a new "dongle-less" version the AP, but have not seen it. Maybe you can check it out and let us all know!? lol

Yes, you can connect your laptop to the OBD with the dongle and ATR. I've done it once or twice when I was bored trying to play with things. As far as being able to flash and watch data, I'm not sure what feedback you're going to get.

This is good news!

This is not. lol

Superskates said you can log with ATR (via a laptop) instead of the AP (and get more data points per second), but I couldn't get it to work. I just picked up my AP ~5 weeks ago, but I'm pretty sure it's the "old" one, bc I bought it for $595 (less discounts), so I'm sure the new ones will be ~7 bills.

Just to carify, do you mean through the AP like I said in the OP, or do you mean have the dongle in the OBD port, and the other end directly into my laptop? If so, where the heck would it plug into my laptop? It doesn't look like an ethernet plug?

Not too concerned about flashing data... I plan on using the AP for that (and logging) until I get the map just right (almost there). But after that, I'd prefer to get a DH and just set a few warning parameters (boost, KR, AFR's, etc..) so I don't have to datalog with the AP and be bringing it in to see that logs "after the fact." Plus the micro USB with the DH will make it easy to just bring my laptop out to download the data.

>>>>> And thanks guys for the input!!

You can get a splitter cable that will allow you to plug more than one thing into the OBD port. Whenever I start using my AP, I'll plug into that and leave the Dashhawk plugged in all the time (I probably will only use the AP to log when I'm doing something serious).

I meant OBD->dongle->USB cable -> laptop. You won't use the AP itself in that config, then use ATR to monitor I believe.

I thought that the OBD could only support one peripheral at a time, that people with the DH and AP plugged in found that it wouldn't let both connect?

Yeah, that's how I had it hooked up. The normal OBD <----> AP <---- micro usb ---> laptop. I opened ATR and tried to "connect to ECU" and kept getting some error message.

I........I thought that the OBD could only support one peripheral at a time, that people with the DH and AP plugged in found that it wouldn't let both connect?

Yeah, he will find out soon enough. You can't have two receivers pinging the OBD at the same time....

That makes sense....

Now what about that error message I was getting? :/

Also, how does the DH dataloging compare to that of the AP... that is, if we're recording the same amount of PID's, which gives you more recordings per second?

I think Steve said no AP in the loop. Dongle to `puter USB

DH has more records capability(a setable option in DH), but only 5 PIDS per log....

You NEED a DH though. It is best for real-time display with 5 selectable alarms.

Thank you kind sir, good info to know! HPFP being ordered within the next couple wees

Okay, but the 'puter end of the dongle ain't a USB... it's some weird thing

that won't fit in my laptop... well without a hammer anyways....

I don't mean to (deadhorse it's just that my Q still has no A (stripper)

Make sure all the things are up to date, and that your USB port acknowledges the dongle drivers.

I'm pretty sure they were up to date, before the recent ATR update, which is when I tried this. I'll definitely make sure to do that when I get my AP back. So, I do use the AP in this set up then, correct?
OBD<--- dongle into---> AP <---micro USB----> laptop USB, correct?

God, I hope so!! LOL

Thanks tunersteve!!

That's weird. My AP uses a standard micro to USB cable where the micro goes into the dongle and the USB goes into the AP. The AP also has a micro port to use the same cable to go from AP to 'puter USB. Just switch ends...

Doesn't your AP have the two ports, a micro USB and reg USB and the dongle has only one port(micro)?

My AP has two ports... one is a micro USB, and one is this weird ******:

Normal dongle, but that weird end is what plugs in from the OBD port to my AP. I know they had upgraded the dongles awhile ago because they were falling out (mine was a b**** to get out), but SU gave me this bizarre dongle. that's why the only way I could possibly datalog with ATR would be through the AP, and it didn't work.

I'm gonna ask Cobb if they'd kindly give me a 'normal' AP with the USB port so I can just swap the USB from my AP to my laptop for ATR.

Doug, you've got the newer style, without the reversible USB to Mini-USB cable. That's why there's some confusion.

LOL, I figured something was up! I would imagine to log with ATR I'd have to use the AP as an intermediary then. I gotta call Cobb this morning anyways to get a ticket # for my busted AP. I'll ask them what the deal is.

Thanks for all your guys' help!!

Dang it! I wonder if the "new" version was made to cut manf costs? Anyway, it looks to be more a PITA than the "old" version...?

I was thinking the same thing. Or it's made like that to idiot-proof it.

I thought I heard something about the old ones falling out, but I may be thinking of the dongles... I know there was a problem with the older ones. If anything, I think the new one is more likely to break. I'd prefer a USB connection, especially if it allow you to datalog directly from the OBD to your laptop.
Whatever, I just want my AP fixed, and get that fuel pump, and then the ic, and, and, and.....lol
