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.

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?

The 11.9 I see is rich, not lean.

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

It's a start, ok?

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.

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.

Still collecting Italian porn TT....

Well that's stupid money.

This is better but still on the high end.

Thats a factory built track bike TT, not that bad....

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!

[70CB750]

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]

That Cagiva is very pretty, btw

[toytuff]

Yes it is.

[toytuff]

I could feel it.    All runs to date.

Let the opinions (you know the saying) begin. 

Target AFR in second picture.

tt

[toytuff]

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!

Can you let us "low techies" know your thoughts on the charts above?

I'm sitting in the bleachers also Steve. 

In the first picture we are looking for the second picture. (pic title "all runs", "sample count", "target")

As you can see with this chip blue is lean, red is rich and yellow is good. The first picture is a combination of all log files taken. Eight ( in total. (all runs, mostly lean)

Took me about an hour to swap chips this morning. Next is to get the same sample count as before. Highway blast, cruise and in town. After that I send all log files across the pond and all data is combined for a new chip. Yes, the bike will be torn down again to replace the chip.

The sample count in the bottom of the first picture reads how long I was in a certain throttle position thus the more cells I fill the better it is. This is why I need to be in as many different positions as possible.

We did not change the trim pot setting. (last picture) Adjusting the trim pot would void all the previous log files as this would change the fueling. The trim will be adjusted when the new chip arrives with a different map and that should be the last time trimming the pot.

Hope this clears things up for you. I'm confused now. 

tt

[toytuff]

Ok, chip is way lean at idle. 14 to 15 +/- but smooths out off idle. Short blast tomorrow. The trim pot needs backed off but a new EPROM is on its way.

We will wait until it arrives, back the trim and run log files. I was told we were getting close. I hope so.

Update: I'm on the wrong page. Not surprising. 

Going back to the second eprom, swapped out yesterday. I need four or five runs to compare data with the custom chip and trim pot adjustment.

So, the first picture shows the reference to pot settings. The second pic (small) was where my trim pot was set. The third pic is where I had to go to get 13.2 AFR. (notice white dots in the pot) This obviously is lean.

Adjusted pot towards rich (pic four) per Adam's test eprom. This gives a richer idle condition. (last pic) We will have to find a happy medium between idle and off idle. We have +0.8 afr @ idle, +0.7 afr @ midrange with this trim pot setting.

I'll run log files, send him the data, merge two eproms then burn a new one.

We should then have a good map.

tt

[toytuff]

OK, if anyone is following along while you are adjusting your idle screw here is where we are.

Ran three (3) log files today with the trim pot turned back. (picture one)

As you can see the AFR is off of very lean to a little on the rich side. (picture two)

And below is the email I received from Adam after reading of all log files. (eighteen to be exact)

Good to hear..

Leaning the idle off a little with a new map will drop the idle a tad..

 See attached AFR and Sample count for the last 3 runs

 It is running a little rich which is what I guessed it would although, not as much as I thought it was going to be.

I should now have enough data to build a new fuel map for you.

 My software will compute the new map based on these runs.

Because we ran both the eproms and the pot change, we have some good data points that were spot on AFR.

I can cross reference these values with what my software computes and adjust accordingly.

Your work is done.

 Cheers

Adam

Sounds like good news and that you are fortunate to have Adam help you out.

How did you connect with him?

Sounds like good news and that you are fortunate to have Adam help you out.

How did you connect with him?

Connected on the MV Agusta forum. Adam builds and sells the data logger. (plugs into ECU test lead, reads data to a SD Card. Data then displayed on software)

Yes, could not do this without him. Do you think a shop would/could do this? Nope.
Easier just to "sell" a eprom, label it race and hope it works on your bike as it is a "general" eprom with very few changes.

Here is a little background from an email I received from him.

tt

Try this.

 You buy a new MV F4 1000 in 2006

You ride it, it is #$%*e

 No one knows anything

 You get a PowerCommander and set it up, but fueling is only half the problem.

You look for a programmable ecu – one shop says he will be doing them soon

 2009

 It takes him 3 years !

And he wants $2500 – stuff that

 Meanwhile, I have studied and learnt the ecu coding, understand and work out a lot of the maps.

Start mapping, takes a year to get all my software and hardware sorted.

 Find a friendly dyno that will allow me to run it to set up and check the top end

Much better but still problems with the engine braking system and transients.

 2010

More studying, work how to re write the actual ecu program, not just the data

 Gave up for a year

2012

Re write the engine braking code

 2013/14

Still not happy with the initial ‘pull away from the lights’

Figured out that MV have put some code in to stop you flipping the bike in 1st gear but it is much too flat

 Re-wrote that code and a few other bits

Built the logger so I could log easier and be able to help others.

 2015 – helping others, and no I’m not retired.

 SEPTEMBER !!!!!

[toytuff]

Quite the difference.
