cheap OBD2 reader and flashing ABS howto fix..

How reliable is the figures for MPG and BHP on these guys?

AndyM · January 18, 2014, 20:41

For MPG I would think pretty accurate as it's just reading it off the ECU and that knows how much fuel is going in and the speed. To be honest though I've never directly compared it to my fuelly stats.

No idea on BHP but I suspect not accurate at all. In fact I don't remember ever seeing it on my reader.

parker455 · January 18, 2014, 20:43

hmmm interesting, does it work off an android phone too? Would like to know what I'm getting fuel wise.

AndyM · January 18, 2014, 21:19

Yep, unfortunately it doesn't work with my iPhone so I use my work Android phone with Torque App.

To be honest though I found it a bit of a faff for fuel efficiency checking so just use Fuelly instead. s:)

Probaly a cheaper way of doing it to be honest, I'll be using that too then. Cheers Andy!

Hi Folks

Old thread, but this seemed like a good place to post. I just bought one of these: m http://www.ebay.co.uk/itm/331568374015? ... EBIDX%3AIT m

It works fine in my Skoda but when I connect it to the MR2, Torque says it can't talk to the ECU. The ABS light flashes but goes out if I flick the key. Do I have to solve the ABS light problem to get it talking to the ECU?

To make mine work I had to plug it in after ignition was on. I removed the abs pins and leave it plugged in all the time now, or at least while I'm running my engine in, I like to monitor certain parameters while I'm still in super cautious mode

insx · July 27, 2015, 21:25

I disconnected pin 14 (apparently "CAN (J-2234) Low") on my reader and it stopped the ABS light flashing but the reader still can't connect to the ECU. I don't think I'm going to have any luck with this one. As it happens, I bought 2 different ones on ebay so we'll see how the other one does when it arrives.

Hello. My first post here. I also disconnected pin 14, but am getting bad data back from the device. Torque connects but the numbers are all negative and non moving. OBD Doctor gives accurate Voltage, but try anything else and it crashes. I've been using the OBD doctor Console, which lets you talk to the device like a old skool modem and the car is responding but not as it should. Going to try disconnecting the CAN high pin also, as the airbag light is on. Will let you know how I go.

Hi I'm having the same issues!

I bought the following reader: m http://www.ebay.co.uk/itm/OBD2-OBD-II-B ... 3a8ff2449c m

I've installed the free Torque app and the reader appears to pair to my device but doesn't communicate to it. I have the ABS issue others appear to have so plug the reader in after starting the engine to avoid.

I've gone on the settings and chosen bluetooth under the connection setting, and the OBD2 option under Device. When I try and reader and app on a 2014 Fiesta it works, so I struggle to understand what's stopping from working with the MR2!

insx · August 1, 2015, 19:00

I've just been through this process with 2 different readers and given up with those. The good news is that the white pro-scan one from ebay does work.

I've managed to break my trusty old OBD dongle s:(

s:( I left it plugged in and I kept kicking it getting in and out of the car...I took it apart but couldn't see anything wrong.

So I've ordered this one

m http://m.ebay.co.uk/itm/231553464641?_mwBanner=1 m

Not sure if it will work but it's shorter (so I won't keep kicking it!)

I will report back

Arrived quickly and works perfectly with no issues, connected straight to my phone and works with all my cars s:D

s:D

Just need to do the Pin mod as I get PAS and ABS lights when left plugged in

Rockingdad · November 25, 2015, 18:08

Hi, although a bit of a thread ressurection....Am I right in saying that if I plug my bluetooth OBD2 in AFTER ive started the engine I shouldn't have any issues with ABS lights etc going mental? Engine Check light came on this morning FFS, I've only had it a week and covered about 90 miles!

After I've sorted this issue, whatever it is, Does the Pinmod then allow youto have the module plugged in all the time without detriment to the data come off it? I've bought a spare one the same as Meeerrrk to mod to be able to have in there all the time (Future Android head unit planned).

Cheers

If you plug in after engine start you shouldn't have any problems.
Not all readers have that issue anyway.
I have the one pictured above which I can't leave plugged in and another which is slightly larger but causes no issues.

Rockingdad · November 25, 2015, 21:54

ok cheers s:)

A bit me being lazy, but will this pin14 for abs also cause airbag light issues? I get no abs issue with the current readers I own, but the airbag light is on dim... something I'm not overly keen on.. and I want the obd2 in permanently for datalogging.

shnazzle · April 16, 2016, 16:11

Mine does the same.
Mind, it used to set the ABS light off and it stopped doing that... Which is odd

stupink · April 16, 2016, 17:17

I've just tried cutting the pin, no luck, the abs doesn't come on, but the airbag light still does, I've no idea how it effects the actual function so I won't be using these adaptors and will stick to my old one that is just big.. i'll just move the obd2 port so that I stop kicking it when I get in the car haha..

shnazzle · April 17, 2016, 07:46

Best one I had was the WiFi dongle with lead. It didn't work on Android, so sold it. Now I regret selling it and wish I had just kept it permanently attached with my old iPhone5 in the glove box

stupink · April 17, 2016, 08:31

This is the issue, I need a Bluetooth that works with android as I want to use it with harrys lap timer for track use ... at the moment I have one huge reader that works perfectly, but only logged at 1hz, I was hoping the mini's would log quicker because they are faster units, but it seems the limitation to 1hz is the car itself as these blues don't log any quicker anyway.. so i'll put my large one back on and just move the port behind the dash or something s:)

s:) if I resolve the issue i'll post any findings.

shnazzle · April 17, 2016, 08:33

Interesting that the car limits the speed. That answers my question as to whether I should spend the cash on a OBDLINK MX.. Granted, 100 PIDs per second probably does make it quicker

stupink · April 17, 2016, 09:08

I think on the older cars it was purely about reading codes, modern cars are aware that data logging is needed and so they run faster communications. i'd love to know if anyones got better than 1hz out the mr2.. and if so how.. I get 5-10hz out my corsa with the same mini adaptor.
