1998 V11EV ECU

[n3303j]

My bike has the P8 ECU that is half covered by the rear seat. I'd really like to get rid of the rear seat. Anything I can do to relocate (or swap for a smaller unit) the ECU so I can leave off the rear seat?

Replace the battery with a narrow one, and put the P8 beside it.

[rodekyll]

Sure.

The efi harness is a stand-alone set of wires that connects to the main wiring harness at a relay, a fuse, and some grounds.  So if you cut the efi part out of a Jackal (or other 15M) harness and lay it alongside your P8 wiring yu can plug it all in and put the tiny 15M ecu wherever it's handy.  The harness is on ebay for $50 or less all the time.  Many bikes use the 15M ecu, including guzzi and ducati.  So it also can be found on the used market.

If you have a link to one for that price, let me know.  The ones I found are $200 and up.

this is very simple to do. get an Oddesey .

I like that option, then you would also be able to use Guzzidiag
My EV had the ECU slotted in beside a fairly large AGM battery.

[pehayes]

Easy.  Might have to undo the brackets so you can move the wire harness.  Stock harness and ecu drop in the compartment alongside an Odyssey 680 battery.  ecu doesn't have a gravity sensor so it doesn't care about orientation.  I added the rubber sheeting just to help insure rain and wash water can't get in too easily.  Done.

I don't know where you shop, but I have never seen that wiring harness anywhere near $200.

Here -- how many do you need under $100?

ECU's can have all sorts of mappings depending on what it was programmed for.  I've had them marked 'cali,' 'lemans', 'ev'. There are others.  One trick is to find a reasonably priced ecu with a yummy map.

[OldBMWMaster]

An ECU is NOT a wiring harness.  Do you have a link to the smaller ECU for $50.00?

[rodekyll]

Golly -- I checked, and you're right.  An ECU is NOT a wiring harness.  How did that slip by me, and what's your point?

[Rainman]

Sure.

The efi harness is a stand-alone set of wires that connects to the main wiring harness at a relay, a fuse, and some grounds.  So if you cut the efi part out of a Jackal (or other 15M) harness and lay it alongside your P8 wiring yu can plug it all in and put the tiny 15M ecu wherever it's handy.  The harness is on ebay for $50 or less all the time.  Many bikes use the 15M ecu, including guzzi and ducati.  So it also can be found on the used market.

  In addition you have to change out the cam gear for a newer one + the toothed timing wheel that sits behind the gear from a 15M bike. Also the P8 engines right hand head doesn't have the mount point for the temperature sensor.
And don't use a Ducati ECU they don't have the air pressure sensor in the ECU like Moto Guzzi does.

  With all that said when I upgraded my '96 cali to a 15M it was like getting a new bike. It ran 100% better than it ever did with the P8. With a huge boost in toque from 2500 to 5000 rpms. And the seating position, with a newer seat that lets you sit back without being pushed forward is the best.
  And now with Guzzidiag if you have after-market exhaust you can flash the 15M as many times as you want for the cost of the ECU adapter.

Hmmm.  We must be talking about two different things.  My P8-to-15M conversion was done on a '98.  It went as I outlined in my previous post -- none of this extra stuff you're discussing.  Was yours originally a P8, or was it a carbie?

The temp sensor is in the valve cover with the P8, but it's there.

The P8 I converted ('98) had a phonic wheel (the toothed wheel behind the cam gear) and cam position sensor.  That part was plug-n-play -- no need to open the timing cover at all.  I double-checked with the manual, and it shows what I remember. 
The Ducati 15M ecu's I've used have been identical to guzzi in every way that I can tell except the label and the mapping.  They all have the little rubber plug thingie for the barometer.

[n3303j]

I appreciate all the input.

So if I have this right I can get rid of my giant battery and move my Big P8 module into the battery box and remove my rear seat.
OR
I can modify my harness, find a smaller ECU, open up my engine, swap a number of parts, reassemble my engine then I can remove my rear seat.

Seems like an easy choice for me.

[rodekyll]

No, there's no opening up the engine if you have a cam position sensor up there near the oil pressure switch.  The 15M used the same, but fewer sensors as the P8 I converted.  There may have been a plug end I needed to splice in fro mthe old harness for some reason -- it's been 10 years since I did it and some details are fuzzy.  But if you have a temp sensor in the valve cover and a cam sensor in the engine case all you need is the ecu and wiring harness stuff as I already described, and an afternoon to slap it together.  You come away with a smaller, more sophisticated ecu placed wherever you want it, for the same effort as relocating the P8.  And you get to keep your battery and sell off the P8 to offset the cost of conversion.

Now if you don't have the sensors you might come out ahead with the relocation plan.  Me, I like the 15M so much better than most of the ecus out there that I'd do the swap even if I had to do the cam stuff Rainman was talking about.

[Rainman]

I stand corrected. It appears there was a change from the '96 '97 an earlier P8's to '97 '98 and up ones. The '97 '98 and newer ones wouldn't need the cam gear swapped out for newer parts like I had to do.

[rodekyll]

Thanks for double-checking.  I was beginning to think I'd crossed some wires somewhere . . .   

[pauldaytona]

When a bike has a p7 or p8, there will be two sensors, one on flywheel and one at cam. When converting to 15m, the flywheel sensor isn't needed anymore. and the cam sensor needs a phonic wheel mounted. Because the phonic wheel is 5mm thick need to change the chain gear of take 5mm off it.
For the wire loom, you don't need a new one, just source a 26 pin superseal that goes in the 15m. Cutoff the big plug and get the new one on. Study an eavening on the wire diagram new and old and you know what goes where.   

[OldBMWMaster]

Now if you don't have the sensors you might come out ahead with the relocation plan.  Me, I like the 15M so much better than most of the ecus out there that I'd do the swap even if I had to do the cam stuff Rainman was talking about.

Again, does anyone have a link for the 15M that is less than $200.00?

Ebay is full of them.

For $50.00??

[rodekyll]

You're the only one saying an ecu can be had for $50, so you're arguing with yourself.  Leave me out of it.

RK said the HARNESS can be had for under $50 -
NOT the ECU!

[twhitaker]

Good information here. I think this is just what I need for my '96 Cali.

[BigDave in PA]

I will ad that as far as I know the 15m ecu will not run the tach that was on the p8 bikes. Correct me if I'm wrong but I think it'a a different part #.

[PeteS]

My solution was to get a Ned's seat, leave the P8 where it was and get the special Power Commander and harness from Todd. Bike ran strong and I could ride the bike all day without discomfort. More than one way to skin a cat.

[twhitaker]

The issue I am having with my '96 Cali is that, for seemingly no reason whatsoever, one cylinder would quit working. After a few seconds to minutes it would kick back in, without a bang. Which leads me to believe I have an intermittent connection in the injection harness. I can usually get it to kick back in by pulling the clutch in and let the bike idle for a bit.

I figured a harness with the big ass connector would be expensive or not available. Changing over to the 15M harness might be less expensive AND better.

A fellow at the New Cumberland rally suggested Seafoam which I'm going to try first.

Until I get this reliability issue figured out that bike is going to be a garage queen.

Pull the connectors off the injectors and make sure the contacts are seated all the way in. I had one move back and only made intermittent contact.

[twhitaker]

I'll do that.

One question not asked. My TPS is the big one that's about the size of a hockey puck. Is the connector the same or would I need to replace the TPS too?

[rodekyll]

I vaguely remember something about the tps.  That might be where I needed to splice in a connector from the old harness.

It was a long time ago that I did this.  If someone wants to make their rig available, I'll come to your house and do it again to document it.
