I just thought i would let folks know of a ecu reader that works on the P38 petrol.

Had runing problems on my 1996 4.6 RR:doh:, i knew the fueling was not right so i contacted my local L/R specialist, who i highly recommend.


AMR Auto's, Grenhow Hill Farm, Pannierman Lane (Off A172), Great Ayton, North Yorkshire, TS9 6QF
Main Tel : 01642 724646, Parts Tel : 01642 724647

they are just outside Middlesbrough and are also an LPG specialist.

I took my car over to them and they put it on their diagnostic to check what was going on and cleared all fault codes then did an adaptive reset, all with me looking over his shoulder so i knew what had been done, and he showed me that the oxy sensors were not correct and the MAF sensor was not working.

He did say the LPG system (single point) was no doubt causing some of the problems.

He left it at that, no hard sell to replace lots of parts and charged £35!! which i thought was cheap.

Any how after looking for something to read the ecu, most sites were saying you need the proper kit which costs at least £300 up to 1000's.

I found some where, i can't remember if it was on here or another forum, that an ELM 327 CAR DIAGNOSTIC CODE READER SCANNER OBD2 TOOL will read the ecu and give live data.

i was a bit sceptic as with most of the cheap stuff as they are selling on ebay for £30.

But i thought £30, is cheaper than going back and forth to the garage and i can play and check thing at home, so i bought one off ebay and guess what:) ''IT WORKS''.:)

once set up with the software that came with it, it gives live time run stats of the engine from fuel trims, O2 sensor voltages and rich or lean, MAF flow rate and a load of other things, but the main thing is it communicates with the ecu, which alot of folk say the cheap ones don;t.

If any ne needs any more info of where i got mine from let me know, there are quiet a few people selling them, but from what i read go for one with LATEST ELM 327 Ver1.3A .:)

Hi,
Yeah it plugs into the OBD11 and a usb on my laptop, i got it off ebay from j1j2m3, the item number for the one i just bought is 110451108889, if you type that into ebay it should bring it up. It came with a disc with software on that works.
 
Yes it will only do the engine ecu, i have previously downloaded software and made a lead for the eas. With time hopefully software and kit will be available or the transmission and becm.

Now need to figure out why bank 2 is weak and bank 1 is rich, fitted new (lucaas) o2 sensors as they looked old. Voltage readings from both sensors the same at idle. :confused:

ive been using the elm327 for some months now, if you check out a site called digital kaos and search there are quite a few free and not so free progs!!!

you can also do engine ecu's on other cars. for the price of em they are very handy to have in yer laptop bag!!!

there are people working on the code for the rest of the car, its a long way off but its still in progress!!! hopefully it wont be too long before our friend storey wilson has something published!!!!
 
to all the people that have test equipment what do you think about this ebay number 300363127349 as i dont have a lap top an thought this would be just as good as the one descibed above
 
the iso 9141 2 is the protocol on the p38 so it should do all that the elm does!!! contact the seller or manufacturer and check tho!!!
 
its a different plug on the classic, i dont think they are obd2 mebbe obd 1??

certainly the elm is no use to ya!
