You guys should see what's coming our way, seems like Canada is missing some cold front or such

Well, I'm surprised. Need some more log files and at higher RPM's.

I'll thrash it some more!

Looks a little lean, did you check the plugs? Has plugs, right?? HA!

And how 'bout a "butt dyno" report. Guessing it's running good if you didn't mention issues and it's ready to go for another run.

scottly · « **Reply #128 on:** February 13, 2015, 06:04:23 PM »

You need to at least open the throttle more than 2/3rds!

As far as remapping, there appears to be a lean tendency at 11.9% TPS?

toytuff · « **Reply #129 on:** February 13, 2015, 06:16:45 PM »

Lean it is. Original plugs, not going to worry about them at this time.

Butt Dyno is wicked fast. Wicked. As you can see I have yet to wind it up over 8k however I was up to 65 in a 45 zone without even trying. I need to be careful on this one. It's a license eater.

So, more riding, more logs. Throttle is very sensitive. Known issue with this model. I felt hesitation in the 5-6K range but slight. This could be riding in to high a gear. The Ducati likes no lower than 4K. I believe this one likes at least 5K. Stalled once when I abruptly closed throttle from second to first gear stop.

Reading a log file I did notice one spot where I had an afr of 19.5. Could of been a throttle off position. I just glanced quickly at the file before dinner. Still learning to interpret what I see.

Bike is 100% better than before but before was pretty bad. I can see a remap on the chip is forth coming. This will take time but I have plenty of that and I'm getting into this a little more each time. At least now it's enjoyable. Wasn't that before.

Onward....

The 11.9 I see is rich, not lean.

Yes, Adam had mentioned a wider throttle. Was in and out of residential areas today. Add to that fresh tires so I went on the easy side of things.

It's a different animal and I need to adjust. I might be older but I am smarter.

It also appears to tend towards rich at 6K RPM and above, regardless of throttle opening.

This is basically stock mapping from another chip from a Dyno run. There was a little timing change and some slight fuel mapping.There is going to be many, many changes in the future. We needed a starting point. This is where it starts.

Welcome to MV Agusta.

There are several samples with lean 15:1 AFR in the column for 11.9% TPS (Throttle opening).

Looks like a track day is in order or a dyno, hard to get the required results on the street....

I was thinking the very same, you need space to collect data.

That would be nice but none around here. Adam said we can tune around the area where I ride the most. Will see how/where this goes.

It's a huge improvement from where it was.

toytuff · « **Reply #139 on:** February 14, 2015, 01:55:19 PM »

Some progress today. First, I found out the chip is not a stock mapping. No biggie. Four log files today, waiting on results. Got the bike out on I-40 for a few blasts.

Adam sent me an email saying we have enough data to start a new map although I want to ride North towards Vegas tomorrow. I'll do that in honor of the East coast weather.

I thought the bike was wicked yesterday. Wind this bad boy up to 10.4K in first and second gear wicked is an understatement.

I'll post the excel report when I get it. Curious myself.

Some of the styling on these newer Italian bikes look like they were done by someone coming down off a meth high, lol! Nothing like the sexy curves of a Taburini-designed bike like the original Ducati 916. Some of these latest offerings from the land of pasta and the mafia are just downright fugly, IMHO.

I have an "Italian sister" for my CB650, my PITA Cagiva 650. Took me almost 10 minutes this afternoon just to get it started, then had to hold the throttle open around 2500 rpms for five minutes before I felt comfortable enough that it would idle without shutting off. But hey, whaddaya expect for a bike that's 28 years old, before all these data logs, profiles, and laptop tuning wizardry became the norm. But once that Cagiva's started and all warmed up, she's a very nice ride, and with those Bub mufflers, sounds like an Italian v-twin should!

You got a point there, I really liked the Honda CBR1100 when they came out in 1996, beautiful lines, you dont see anything like it in modern motorcycles.

70CB750 · « **Reply #145 on:** February 15, 2015, 01:37:29 AM »

That Cagiva is very pretty, btw

All runs to date.

Target AFR in second picture.

Tomorrow is tear down day. The second EPROM I have is the mapping that was on the bike to begin with. Some fueling tweaks down low (rpm) in the map according to Adam.

With the trim pot now set to 13.2+/- up from 11.2 will see how it reads. Adam said it was close to our target map posted above.

When done it's off to ride and record log files. This data will be used to create a new EPROM. Shipping time involed so we are looking first of March.

The EPROM in it now goes back to England. Bon voyage!
