ETM software

[precopster]

Doublebug is a very skilled an amazing man. He located and transferred sw from his database to a used ETM for me and I finally have a normal smooth idle and cruise control after giving away my ETM to a customer last year.

Can anyone point me to the correct procedure for transferring the software from the old to the new ETM, please?

The ETM in my wife's V70 has just failed, and I'll have to replace it with a new one, because the old is nearly seized - I can barely turn the butterfly by pushing it, and the spring is unable to return it to its original position when released. I guess the bearings and/or the magnet in the motor are dirty/rusty?

Thanks!
Pepsov.

What year V70 is it? PM user doublebug (upthread) to arrange the xfer if you have DICE, otherwise its a trip to a dealer or someone with DICE

If you're very patient, have soldering skills and can spend afew hours on disassembly it can be fixed.

The magnet has an aluminium sheathing around it. This can be cut off with a Dremel tool. Under this you will find loose iron filings which are grouped at both exposed poles. The iron filings expand either through vibration or moisture entry and cause the aluminium sheathing to rub against the armature.

You can remove all the loose iron filings by scraping them off with a toothbrush. The bad part is that the plastic cover over the magnet can now slide sideways over the poles. To avoid this movement you can centre the plastic cover & set the plastic cover with silicon sealant.

The magnet is now clearanced away from the armature (or windings) It will never scrape again and cause a stuck throttle or blown fuses.

Dear Mike,
Yes, I discovered similar things myself by carefully and patiently disassembling the ETM (thatnks to all the information in this and other similar threads in this forum!)

I did not cut the aluminum sheathing, but simply pressed the expanded/bulged parts of the cap back, by inserting increasingly thicker layers of kapton tape between the windings of the armature and the aluminum cap, and then rotating the throttle plate until finally I got the magnet to move freely. I was either lucky to not brake anything in the process, or truly brilliant to find a solution that did not require cutting of the sheathing

The ETM is back in the car now, and works fine. Apparently the brushes of the potentiometers are still fine (the car has 175k miles in 15 years), but I want to do the SACER mod, because the brushes will fail sooner rather than later.

I went on and purchased the SACER set (for $112) and got an ETM module from the junk yard (for $50), and installed the SACER in it. Adjusted the idle voltage to 1.37V - exactly as it was on the replacement ETM before the mod - and tested it. It works, but I have the rough idle and momentary hesitations described here by so many people, which I attribute to the firmware version in the replacement ETM being incompatible with my ECU. I was getting systematically P1017, P1020, P1021 and P1025.

So, I am driving happily around with the original ETM now, and am looking for a way to copy the software from it into the replacement one. That would be a more lasting solution.

I wrote to user "doublebug" but never got any response. Do you know if he's still active in this forum?
Is he the only person who can walk me through the process? I am pretty familiar with programming all sorts of electronic devices, so a brief list of general instructions might be enough.
I have a general-purpose OBD-II reader (ELM327 v1.5), but do not own a DICE. I am willing to invest in one though (any recommendations? A particular "Dice Pro Plus" model seems to be rather popular these days - any thoughts?). I have a working VIDA on a laptop, so I'm almost set for the operation.

pepsov, I've answered to your message but seems you have not received it.

Henry is the only person I've encountered that can handle Volvo software transfers from one module to another. More often than not he has the firmware in his database.

Just so readers of this thread understand what is going on, Henry is actually transferring the software from his database to your new ETM. Sometimes his datababse doesn't have your particular firmware so he will then backup yours and transfer it over the internet to your car. Your Vida software has no value in this operation. It's the Dice tool that allows transfer via Henry's own transfer software.

Last night my wife's'04 XC70 started up running rough, info screen read something about poor performance, would throttle past 2000rpm, then CEL goes on with P2111. P2111 stated something about throttle acuator being stuck open. Where is the throttle actuator for the ETM? I thought the old V70xc had all the ETM issues, I a '98 V70 XC without the ETM.

The 2004 has a much better ETM, it's the 1999-2001 Magnetti Marelli ones that cause trouble at about 100k miles. None of the stuff in the ETM threads will apply to the 2004

Thanks for response, actually I know what happened, there's a spring loaded actuator between airbox and l/F head light that I got my latex gloves caught on which in turn pulled it apart causing issue.
