V7 Classic reflash ECU and Mistral Crossover Pipe questions.

[malik]

To clarify a little - the V7Classic has the 15RC ECU. This ECU seems have built in quite a bit of flexibility and also seems to have well sorted out of the box. For the 15RC, you do not need a reflash for the crossover (I didn't for the Agostini), you don't need a reflash for Staintunes, you don't need a reflash for Agostinis, & probably not Mistrals either. The 15RC copes/learns.

That has been my experience with a late 2010 V7C (map BC.0103278.A). Joe's 2009 V7C seems to have been unsatisfactory, hence the myECU upgrade, but the later factory maps seem to be fine.the Breva's & I think, the Nevadas have the same ECU, & probably the same maps.

The latest factory maps should be available from your local friendly Guzzi dealer, and FREELY available from Beetle (GRiSO.org). Beetle's free map is for the 15RC, and thus is NOT appropriate for the later single throttle body V7's. Do note that if you have a muffler with removable baffles, removing these may change things. My V7C seemed to cope with the Agostinis with the baffles removed, but I found it too loud  (sorry Al) and quickly restored them. I don't know what would happens if you started putting holes in the mufflers, do so at your own risk, but I wouldn't recommend it.

I think that about covers it.but do ensure that everything else is working well - throttle bodies balanced, fuel filter not blocked, air filter in good nick, no leaks in the exhaust system, good plugs & caps & HT wires, etc, etc, before you start fiddling with the ECU.

Hi Beetle! Thanks for this! Question, will this map work for all Guzzi V7's including current ones? I have a 2013 V7 and I just ordered the cables but I want to be sure I'm not shooting myself in the foot. If not, could someone point me in the right direction? GuzziTech seems great, but for me, I have a used V7 that cost me $3800, so paying $500 to fix the ECU, is pretty steep. I feel like this is more of a fix than a performance increase.
Meaning that the stock mapping with lighter and less restricting mufflers is almost unridable. THANK YOU

As Steve and Mal have pointed out, it's only for twin throttle body V7 Classic/Nevada/Breva
My maps for single throttle body V7's are 1/5th of the price of a GT map. And far superior.

Malik,

My '09 V7 with the 15RC ECU was fine right from the factory.  ...  Until I added big bore pistons and cylinders from Italy.  The added displacement sucked more air (like it was designed to) but that just leaned out the mixture and I had knocking. 

MyECU was great, allowing me to adjust the air-fuel mix and timing to remove the knock.  Before that, the big bore kit was a huge detriment, but the total control of MyECU resolved that.  MyECU is only available for the "old" engines, not the new single throttle body motors.

And...when it was stock I did play with a DIY O2 sensor mod.  It worked well and I recommend it, but I know others have had problems.

"Todd" over at Guzzi Tech reflashed my 2004 Breva 750 in 2013.  It made a real, major,  improvement in tractability and fuel economy.

It was a mail-in-the-ECU process which took about 10 days round trip.

Don't have a phone # or email for Todd but you can send him a note here:

Also here's a link to GuzziTech where you should be able to find Mr. Eagan and his services:

I understand how that might change a few things in there, Joe. Must be satisfying. If anything like taking one of my Enfield 500 singles out to 535, that little bit extra made a comfortable increase in rideability. nothing startling,  a tad more torque.(handles hills better), a tad more power,  along with confidence that the crank's hardening wasn't going to wear through anytime soon. (I got the bike cheap because the crank had failed).

The O2 spoofer? I tried one out (the one from Corsa Corta) for a few thousand km, not a success on my bike - more popping, spluttering, engine warning light flickering, missing at 4,000 rpm. Removed it. I'm now unsure that the symptoms were solely due to the spoofer, but the bike seemed to run better without it. John at Motociclo reported that it worked well on some bikes, but not on others. There have been reports of detrimental effects in long term use. Now that there's more people around who know more about maps, it seems to me that it's better to make adjustments through the ECU rather than on top of it.

Anyway, I'm still happy with the V7C, gets me from A all the through to Z, and in style.
