Reprogramming BECM to ECU with HAWKEYE

Due to a false alarm when I unlocked the key the P38 would not start, just cranks over, no spray from the injector pipes.... stop solenoid operating, lift pump operating.

I bought a Hawkeye instead of a Blackbox syncmate as I wanted to have more diagnostic functions -

As it was nice, I decided to have another go at the Hawkeye and have now found all menus and features and done them all, everything works apart from a few door outstations which I know about
All serial comms are fine and Hawkeye still saying "lost comms with the EDC FIP" which is logical due to the false alarm

I have found the EDC/Motronic code of 0768
The fob code of 153-153-153
And in the Hawkeye it says (under body electrics under security code,) I have found 0940 although I don't know why this is here, sometimes it is 0000 – depends on the time of day

Fuel pump on ignition on and solenoid are now live ( 5 seconds then off and on respectively )

I would like to know if anyone has successfully done a resync of the BECM to EDC 1.3.1 controller with HAWKEYE - and the sequence. Do I have to unblock the BECM to do anything - and if I do does it cock it all up?

Cheers Eddie

Since when has a Hawkeye had more functions than a Faultmate? You certainly don't have BECM direct access for example.

The code in the BECM has to be the same as that in the ECM or they are out of sync and engine is disabled. Don't know if it can be done with Hawkeye certainly can with a Syncmate or Nanocom.

As someone who has tinkered with these Becm "Things" over the years, unlocked them and read the coding data with the BBS Direct Memory software (SM035), I find some of the coding you have obtained to be a little strange.
Firstly I am looking at the FOB code which consists of three identical sets of numbers (153.153.153). Whilst it may be possible that this is in fact the case, I have never come across this in all the time of unlocking many Becm's.I would treat this with sceptisim until it was confirmed by an unlock and read with the SM035. The same applies to the Engine EMS data.
I appreciate that the coding data can be read on an unlocked Becm with the BBS Becm module SM022 and I would be far more inclined to accept those readings than from the Nanocom.
In all honesty though, I have no "Hands On" knowledge of the Nanocom but feel very confident about my knowledge and use of the Rovacomlite and Faultmate.

EDC code is embedded and connot be changed. Something, probably outside interference has altered and still is altering according to OP code in BECM. Code in BECM has to be same as in EDC or engine will not run. Nanocom can resync BECM/EDC don't know if Hawkeye can. Nanocom is much the same as Faultmate. Maybe a little less capable but well good enough. He is reading with Hawkeye not Nanocom.

If you want your Becm unlocking let me know, and... where are you?

Sorry, I misread the post..It is Paddy's Day after all, plus the Rugby result !!!

The Hawkeye, I know nothing about at all...capability wise.
With the BBS stuff you can't access the coding data with the Becm module (SM022) unless the Becm is unlocked.

Ah Jaysus John, don't mention the rugby, ye gave us a hiding :Cry:

Don't fall off that barstool, between the Nordies beating the Offaly boys in the hurling and the Sasanachs beating up the rugby boys there'll be a lot of grumpy leprechauns around Edenderry who might not be able to take a good old ribbing

Happy Paddy's Day :beer2:

Never known the pub go so quiet on a Saturday evening in Edenderry !!!
Looked like a room full of smacked arses !!!
Makes a change for the slagging to go the other way !!!

You can't do reprogramming of any sort with the Hawkeye. Its primarily designed as the home user version of Testbook and made by the same people (Omitec). Presumably in order to keep Testbook in business they allow the Hawkeye just to read and clear faults and to do minor resets like EAS calibration and engine ECU adaptive trims. Not having the ECU/BECM resynchronisation feature however was a major omission in my view.

If Hawkeye won't do a re-sync, it's a total waste of money IMO.

Looking at the topics posted over a period of time related to P38 system problems, these seem to fall into only a few categories...Loss of synch., EAS, HEVAC and SRS. Very few problems are Gearbox, Engine and ABS ECU related.
The EAS free software is a capable piece of kit which sorts that area out.Next comes the loss of synch. which can be sorted in the main with the Synchmate. HEVAC faults generally are Blend motor related and apart from recalibrating the blend flap motors after replacement, software is rarely used. Over the years, the main problem with SRS warnings was down to the car being stood for a good length of time with a flat or missing battery and easily cleared.
I feel the best option is, if you wish to cover all possibilities, get a single vehicle Faultmate or Faultmate with Becm module SM022 and purchase individual applcations as needed with the exception of the EAS which is free.
It is not possible with any of the kits out there, including BBS, Test Book etc. to access the coding data within the Becm if it is locked and my advice ,if you are concerned, is to get the Becm unlocked (Cheaper than the unlock module) which will allow other kit to read the coding data and initiate a resynch & disarm.
Faults can be read with some of the stuff out there but can only be cleared if the relevant ECU is FULLY accessible...as per the Becm.

Bloody hilarious.

Hawkeye's. I could guess a better diagnosis that what one of those could pull up.

All those settings that were read are clearly wrong.

Chuck the thing in the bin & go & buy yourself a nanocom if you can't afford the extreme MSV.

I agree with all of that except that for most folk the Nanocom is now a cheaper option than the Faultmate unless you need direct access to the BECM

Hawkeye was pitched at the level of the Faultmate FCR and is more capable. Its a little unfair to compare it against either the full fat BBS products (which are more expensive) or the Nanocom (which didn't exist at the time).

I agree that at present Nanocom looks like the best option for a P38 owner. L322 owners can also opt for AllComms which is neither VIN or typed locked and has a slightly lower price. There are reports in this forum however that Nanocom can't / couldn't access the HEVAC ECU which Hawkeye can.

My personal experience with Hawkeye is that its a robust product and does the few things it was designed to do with an absolute minimum of fuss and bother. If I need more then fortunately I have access to Testbook and to Autologic. Between the two I rate Autologic higher but boy is it expensive!

The glitch with HEVAC access is I believe fixed

Nanocom sometimes failed to clear Hevac faults. That has now been rectified. Think the Nanocom coverage is far greater than Hawkeye.

No argument here.

It sometimes take me 2 or 3 goes to read the hevac, but the that might be cause its got so many faults!!

Sorry to intrude, but I'm just ordering a Nanocom Evo. Can someone please clarify, if I can disable my feckin alarm and immobiliser with it? My BeCM is locked. Thanks.
