So I been driving, getting some tuning experience and Im having a few issues. One of which, Id just like to understand why.

In between shifts (casual driving) the wideband (Innovate MTX-L) will sweep to 10.xx -11.xx AFR for a split second and return to normal. I looked at that part of the map (the first column) and leaned it out but it didnt changed anything.

Anyone ever experience this? The MTX-L is grounded on the thermostat housing and everything was installed as per instructions. I never noticed this before so its hard to say if it's something I did or if it's a faulty o2 sensor. It seems to be working fine all other times though.

 

Decel fuel cut-off isn't "tight" enough for your style of driving. Depending on what you're running for management, you'd want to decrease the threshold for invoking decel fuel either via. TPS delta or load.

 

same as on pgmfi, adjust tip-out in Neptune.

 

Depending on software you may not be able to adjust the first column. Also tip-out is probably off. I would use columns 2-4 for part throttle and see what you come up with. Again, dependent on the software your using.

 

Yes, I am using Neptune and got an idea of what to adjust now. Just gotta figure out how to do it with neptune now. There is a tip in correction section with tps adjustments so Im going to fiddle with that. Where's JR when you need him, lol. Thanks very much all

 

You can post on Hrtuning.com JR replies incredibly fast on there.

You didn't mention NepTune in your first post. If you can't clean it up go ahead and shoot me an email.

 

I am right now, lol. Thanks

 

Have you figured this out?

 

Unfortunately, I havent

JR gave some good advice about fuel cut. I tried messing with the load threshold but it affected my low load cruising in 5th gear... Car kept cutting fuel and felt like the throttle body was faulty, Lol.

My datalogs do show that the injectors are still spraying in between shifts and under 4% throttle so I know this is the issue.

Its been kinda cold so I havent driven the car lately... Planning to take it out next week and tinker with it again.

Mine is doing the same thing as yours. Let me know once you figure it out.
