ECMspy, megalog tunning

[buellrobot]

Hi all,

I've got an '02 x1 that I'm preparing to tune – I've followed the guide that Gator put together here, and have set my static timing and reset my TPS.

My question is: do I add 2-3 points from my rear to my front maps for a tuber? I know that's true for newer Buells, but I've also heard some say you add 5% or 10% for tubers, not to mention the stock difference between front/rear on tubers seems to be higher than 2-3.

Feedback appreciated!

do I add 2-3 points from my rear to my front maps for a tuber?

that is nonsense.

I know that's true for newer Buells

no, not true. that's just the usual internet bullshit.

but I've also heard some say

stop listening to blockheads. read the tuning guide v2: http://www.ecmspy.com/tgv2/guide2.shtml

I know this has been asked but I saw no answer : when I go to save the analysis that was run by Megalogviewer it says "error saving msq. file, see log file for details". I have windows 8 if that matters... THANKS!

 

[DcBueller84]

disregard the last post. I had to run megalog viewer as admin..

 

[DcBueller84]

so I loaded my first new map made with megalog. followed everything to a T. bike runs better no popping but when coming to a stop the bike stays at 2000 rpms for way too long. some times it returns to idle sometimes it says a 2000rpms. any ideas?

Thanks for this guide, I've been loosely following it with my Buell and it's been improving the ride every time. Got a question for you guys - how many iterations of the log/analyze/adjust routine should you expect to do before you get it to where the AFV doesn't creep very far?

I posted about my experiences on my blog - I've been using a spreadsheet I set up to help me analyze the tables after the VE Analyzer is done with them, I figure it might be of use to some folks - here's the link to the post http://bradfello.ws/159/datalogging-and-tuning-my-buell/ ...

And a screenshot of the spreadsheet:

I am confused and concerned about the front/rear map disparity. The tuning guide says you can reduce fuel in the front for more fuel economy because it gets more cooling air on that cylinder, but gatorbuell says you need more fuel in the front jug because of increased airflow into the chamber in the front. My stock rear maps seem to be significantly more rich than the front and I would presume that is due to trying to keep it cooler.

Does anyone on here have some solid data to base which way to fuel the front?

 

[snrusnak]

I'm no expert but I'd expect the rear cylinder to have more fueling to try to cool the cylinder due to it being shrouded. I don't understand when you say the front cylinder had increased airflow??? Both cylinders draw are identically from the throttle body.

I'm aware of that, I was just regurgitating something gatorbuell said in his first post in this thread.

Need a little help. I recently loaded ECMspy and Megalog onto a different laptop. It is creating the logs with no issues but when I run VE analyze it is telling me (for example): 1 out of 603 logs read. 99% of logs filtered. And basically has no useful information. I did not have this issue when logging with this laptop. I have logged exactly the same way with this laptop without issue. Any ideas on what is going on?

Thanks
Ken

Check out the parameters you have set for the filter on the VE analyzer... Something somewhere in there is making it filter everything normal out...

 

[HooliKen]

This is what it is telling me:

Never had this issue before and not sure how to fix it. I changed parameter for filter and still no bueno.

 

[HooliKen]

And just for the record. I have the filter set to off in VE Analyzer.

 

[HooliKen]

Wanted to update. Updated Megalog and it fixed the filer issue.

Been looking for this program. Thanks all.

Gettin ready to use ECMspy, just waiting on the cable. But I've been doing some reading on there website. And believe I have to do process 2. But I mostly just want to do a tps reset. Then go from there.
My question is when it asks if I have, standard control. Are they referring to my ECM, stock or race? I have a race and don't know if I should put the stock back in.
Sorry if this was the wrong thread to post this, I just searched ECMspy and seen this was the most current.

Thanx, DiRT

Brilliant tutorial, hats off to the author.

i've a question regarding step one. After you've ran the ve analyzer it says "If I had any numbers go red I put them back to the original numbers for now"

why is this?

I take it that its reducing pulse width, why is that bad?

Thanks

ok, heres another question. After I datalog I've read in the Buell tuning guide that I need to change the values AFV to Afr, EGO Corr. to Gego, and EGO Volt. to O2. Only problem is there is no EGO Volt in my sheet? What's up with that? Did some things change since tuning guide was written. I've noticed there are Gego and 02 lines already in there. Also this thread says nothing about it? Do we no longer need to change these values?

Doe this procedure work on 09 xb12r models sry for the noob question its just im fixing to buy this and order cable so I can tune myself because I can't find no one that will do it im lil nervous but I guess I got no choice
