Here are my tables. I am still getting a few pops when using engine braking coming down from about 3500 rpms. It pops when it gets to about 2000 - 1500 rpms.

 

Take the top 3 rows out of closed-loop by setting them to 13.something, say 13.8. Will likely make the engine run cooler and fix your popping.

 

Like this?

 

Yup. Might need to play with it a bit, taking it down more if you need it.

Won't do any harm and won't effect the MPG as you use little then anyway.

 

Will do and thanks Foxster.

 

No. Adjusting the top rows like that are only richening up your idle and low rpm areas up to 1250 rpm. You have to adjust the left hand column. You just have to be sure you are not operating at less than 30 kpa at light load/cruise. If you are and you lower the 20 kpa column you may experience surging in that area as the ecm will interpolate the value between the 2 columns.

 

CVO mechanic told me that would happen and there was a reason for it...but I suffer from CRS and don't remember why but its intentional to richen the mix up around 1750 down with no throttle and that can cause some popping due to unburnt fuel igniting in the hot exhaust pipe getting fresh air on the reversion wave.

 

Could I do a smart tune and run it up to 4000 rpm and then let off the throttle and then hit the record button and record the data down till it pops? Then use that to edit the tables just for that area?

 

I would data log a ride. A lot of times if your bike idles at 30-32 kpa you can actually cruise in the upper 20's. Every bike is different, thats why I like to road test after a tune. Then I know where the bike operates. Try and get some data in the light load/cruise area. flat road where it takes very little throttle to maintain speed. Then get some decel data, different gears. I wouldn't do it in smartune mode. Some calibrations turn the injectors off until 1750-2000 rpm and that is where you can get a pop also. You will be able to see this in the data. Once you have data you can see where to adjust.

 

[quote=1Canuck;9920744]Post 1331 was a different issue, that the updated values change back to some other value as soon as you hit save. The question on my last post was really 2 parts 1. whether that tune was done properly or was it just a few manual tweaks to a canned file and 2. could they have changed the ECM without loading the same config file to the VCI?

I'm really not trying to be difficult or confrontational but it seems that you can very seldom get consistent answers to any questions. There are differing opinions on almost every post. I'm trying to find out what works, and so far I haven't found it. My original problem is that I cannot seem to get rid of a ping that I'm getting from about 2800 rpms to 5000 rpms. No matter what I've done I can't get the damn thing to fatten up or cool down. I hate to complain about it but I consistently get better than 48 MPG, and I know that is too lean. On a recent trip, fully loaded, and rarely under 75 MPH I got 52 and some change MPG.
