After the last issue with the 122's ECU I did a bunch of looking up part numbers for ECUs to see what all I had in the garage. Anyway, I had one ECU which is just like this one:
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2441221672. The Bosch site says this is for a '72 or '73 164E, but this is not the first time I've seen this p/n ECU in a 140. The p/n's I've seen for the 142E are 0 280 000 034 for the '72-'73 models. I've not found anything for certain on the '71 142E . Anyone know what the definitive answer is?

Hi All. The numbers I have for Aussie 140's-164's are:
0 280 000 009 - '70 B20E
0 280 000 017 - '71 B20E
0 280 000 034 - '72&'73 B20E
0 280 001 009 - '71-'75 B30E

We don't have B20F here.

Notice the 4 banger is 000, the 6 is 001.

Cheers,
Paul.

I beleive the Bosch site is right. It should be a CU27X for a 73-74 164 .. It even has the correct bosch (0280001009) and Volvo # 5-243126 that is for the 6 cyl. I found ref to this being correct on 2 other sites besides the Bosch one. Not sure why he is listing it as 140 brain.

See, this is where things get wierd. I have an ipd adjutable brain with the 001 009 part number. This says it should be a 160 ECU, but ipd says they never made an adjustable unit for a 160. I had this in my 122 for a year before realizing the number. Ran OK, but would idle low and stall if I didn't tap the gas after 20-30 minutes of driving. So now I have another ECU in there while I try to resolve the whole part number issue. Saw that auction and went back to the Bosch web page and was just as confused as ever...

What other sites are you getting part numbers off of? As I mentioned, I don't have the p/n for a '71 142E ECU.

Justin, I have a '71 142E ECU... if things thaw out a bit later today, I'll go look at it and report the number(s). Should be exactly the same as for a '70-'71 1800E, if anyone has one of those handy to look at.

I'd imagine it would be the same, yes. 0 280 000 017. Hopefully. I'm still so confused, though.

How's the new place? Besides cold, it sounds like!

The heck with thawing out... what am I, a wimp?

Part number is 017, just as you say. What exactly is confusing you?

New place is just great, thanks. It's not all that cold out really, but we're in the middle of a forest, and very little direct sunlight hits the ground in this season, so night frost isn't melting during the day right now.

The county is also frozen about finally issuing a building permit for our shop/garage, so all the shop stuff is stored under a tarp out by the end of the house. Maybe by Christmas...

"What exactly is confusing you?"

How I ended up with an adjustable 160 brain, and why the 122 runs fine with it, minus the idling issue. I guess that makes it not totally fine, but it certainly runs great up the canyons, etc.

To further add to this, if the ECU and everything else in this auction indeed came from the same car, where are the other 2 injectors? And why have I seen at least a half dozen 140s with the 160 ECU?

Place looks great! That's a porch off to the right, right? Man, I wish I had a nice porch like that. I'd just read the paper and drink coffee all day! Glad you're finally moved in.

You and Amy are welcome to come sit on the porch and drink coffee anytime. The paper's kinda thin, though, and only comes out twice a week...

No idea why 164 boxes found their way into 142s (and BTW, there were at least three different 164 ECUs in the U.S. market). Could be Volvo ran out of the 017 boxes and already had some of the others on the shelf, so in they went -- we know that was common practice in other areas of the car. Close enough, I guess.

You're fouling plugs after 20-30 minutes or what?

No fouled plugs, the idle just gets lower and lower until it won't stay going with out a light foot on the pedal when you're at a light. This is the 160 adjustable ECU. The B20E ECU always runs fine but has noticible trouble keeping up with enrichment needs when you really get on it, say trying to pull out of a corner without downshifting. One of these days I'm just going to put the ipd box on the B20E ECU and be done with it, but that takes motivation I am lacking.

Only semi related - I know my '71 1800E had a different model on the ECU - I think it ended with '008'? The main difference (only one I know of really) is that the earlier cars had an ECU controlled colt start valve, and the later ones were just wired directly from the starter through a thermal timer switch to the cold start valve.

When my original ECU fizzled I couldn't find the proper replacement (pre-internet days) so I just used a later model ECU with the IPD mixture control. So on cold days the cold start valve doesn't work, so I just give the throttle a few pumps and turn the adjustment up to +30% which seems to work acceptably.
