Lean pop, jumpy engagement, start issue fixed

[NOS-PRO]

After I had my 14 XTX re-flashed....I noticed kicking back when trying to start the sled (warm or cold), a lean pop at engagement rpm between 2,700-3,100 and just not smooth like it used to be. Think of One Stop Performance's sled sitting on the 2-step just before they are going to make a run.....close to that.

I have the PC5 on my sled and my AFR readings proved to me that the system was richened up on start up, but showed lean on my AFR readings.

Thanks to Shagman for getting my computer hooked up to my PC5 and changing my fuel settings between those rpms. The PC5 is really cool when you can change these issues by just changing a number

The sled starts perfectly once again and very smooth with a 2,700 engagement. Another feature is the new display allows the user to record rpms and AFR readings. I made 2 recordings but haven't downloaded them yet.

My Cat 7000 is doing this after the flash also. I have been thinking about getting a PCV but I'm not sure if anybody has a flash that I can download that will work. My sled is stock other than Clutching. Will a PCV program from the Yamaha work on a Cat?

did you mean it correct the starter kickback issue?

Yes it will.

Yes, it corrected mine

 

[KwBsled]

is it correct it with stock pc5 maps? or did you have some link to download the good one!

Shagman helped me correct the map that was in my PC5.

Basically concentrated on the rpms 2,750-3,250 and throttle percentage 2%-5%. Map was at -10 at all these points and we richened up to 0

Runs smoother through these rpms now instead of the pop, bog and then shoots up to 4,000
