ECMspy, megalog tunning

[TwistedFocus]

Excellent writeup. I have a question though.

I have done the log/tune/relog process a few times and I am now at exactly 102.1 AFR dead on, high and low. Does that sound normal or should they always be separated some? The bike seems to run well, but still has a small amount of flutter/chugging at light throttle low rpm situaions such as crusing around town at 2100-2300 rpm. This is a race ECM and I already have the white wire disabled, but I still have some stumble in that range. Any tips?

Do you think I should just keep at it until am at 100 AFV constantly?

Thanks

Yea keep going until your at 100. Mine stays at 98% thats as close as I could get it. That stumble is a fueling issue, Gbalias figured it out and posted the fix, Link

 

[TwistedFocus]

Very helpful, thanks. I tried the fix from Gbalias on my current "close" map and its much better.

Now I'm off for some more logging. Just to make sure I'm not chasing my tail here, I am repeating logging steps 1 and 2 in order each time, ie:
-logging with open loop learn and stuff off
-Use MLV to make a new map from that log
-flash that map and re-enable open loop learn, etc.
-log again
-use this info only to verify my AFV min/max for that run
-Back to disabling the open loop learn, rinse, repeat.

Or should I be making a map from the second logging run using OLL? I think I am doing it right. I'm just unsure because AFV only changed by .1 the last time and it's still a little off 100. Maybe I'm impatient... actually I know I am.

Thanks again[up]

 

[GatorBuell]

are you locking your afv at 100 min/max and turning off the closed loop learn enable to log. Megalog ve a new map then turn everything back on and go for a good ride and see if the afv moves.

You will know when your as close as you can get the over all change will only be a point or two per cell. If your that close change your setting to hard or very hard if you keep logging in the ve analyzer advanced settings or you will just be chasing environmental changes.

 

[TwistedFocus]

That's how I'm doing it, so I must be on the right track. I may do one more before I switch up to hard.

 

[GatorBuell]

Make sure you reset your afv at 100 in the diagnostics page before you log. [up] Sounds like you on the right track.

Hi
great info. 07 XB12X Got a question about ignition timing. Comparing the fr\rr ignition tables the rear timing at 7000 rpm 10-60 tps is 20' less than the front. Anyone shed any light on why?
thanks

 

[GatorBuell]

Im lost when it comes to timing. You might want to start a new post and ask that question.

 

[useless]

Well I made the rear timing the same as the front. Made a few adjustments to smooth the curve. Been logging and analysing, bike seems to be running OK. Time will tell
cheers

 

[gbalias]

consider it a soft rev limiter. kinda.

 

[useless]

Just seems odd, one cylinder having retarded timing at hi rpm. XB9 map doesnt, looks like all the units using GB231 have this retard feature. other firmware doesnt. The soft/hard limiters are still available to be adjusted.
At least we have things to adjust now, just like the good old days

Could someone give a simple how-to set values to 08+ fuel maps by hand and then upload them to bike. Edit the .msq file and then upload as normal with ECM spy, that simple? What are the most predictable things I would do wrong, and how easily do I fry the whole ECM?

Thanks!

Let me start out by saying thanks for the great write up GatorBuell [up][up]

I just bought a 2007 xb12s (my first ever motorcycle, besides my scooter), and am new here to the site. I had a quick question regarding changes the ve alayzer suggested (hope this is the right spot to post).

Some posts I've read say theres something wrong if it suggests taking more than 2 points off any cell. However, in some cells its taking off upwards of 9 points. Is there something wrong with this? Heres what it looks like:

The bike had an AFR of 95% before I set it to 100 if thats any kind of explanation for it taking off so much fuel?

 

[dallasb]

Quick question....in the ecmspy guide it says that you need to add a percentage of fuel to the front cylinder...and maybe I'm misunderstanding...but Gaterbuell is stating that we only need to add 2-5 fuel points to the front map. Will someone please clear this up for me.

I do the data logging on my MacBook Pro, running ECMSpy in Parallels Desktop. If anyone else wants to do this, I'm having to use a program called InsomniaX to make sure the laptop doesn't go to sleep.

You can download it here.

[Jabaniz]

how do you know it has a timing problem? did you check static engine timing?

 

[nzaneb]

Just wanted to say Thanks for this easy to use guide to get me started tuning. I spent the weekend dialing in my fuel maps, and am EXTREMELY pleased with where it's at. 2004 XB12R with a Spec Op's pipe, K&N (open airbox)and breather reroute. I have absolutely no more back fire and no more sputtering while crusing. Awesome stuff here. Rep for you GatorBuell[up]

Ok the tunerpro beta for the ddfi1 and 2 for complete datalogging is out. I have the ddfi3 80% done waiting on Mark at tunerpro to do some proofing. this logs everything so you get a great bank of data. plus is set up so you delete one line in the csv export file and it runs in mega log as normal. with this log file it has all data in the logs so its 100% better than ecmspys datalog. your maps will get better 100% faster.
