Tuning Program: Neptune RTP
Wideband: Innovate Lc-1

Question is why does my AFR jump to weird *** numbers. On my display gauge it only reads up to 21 when the car has no load and coasting. Which is indicated by 0.1 on Neptune but every datalog I will get some awkward numbers going up to 30 on NEPTUNE. Is this normal with an lc-1? Or is my something being retarded?

Heres a video to explain what I'm saying.

Firstly, the video is private so we can't watch.

Secondly, you haven't mentioned what method you have the LC-1 connected to NepTune with. If it's Direct Serial, NepTune shows what it receives from the unit. I don't cap it at a certain a/f, which is probably what the gauge is doing. It does send some ridiculous numbers when there's no fuel (In decel or with the car off). Nothing to worry about.

 

Video is fixed. But yes its a direct serial connection from Neptune with lc-1.

 

There you go. It doesn't matter what it shows during free air or decel as long as it's showing you the correct a/f during operational parameters. That's just the a/f value the Innovate outputs during those periods and I don't skew or limit the values that come in.

 

Thats what I thought, but from time to time during cruise it will also do it. Doesn't bother me too much, just wanted to make sure its normal.

Thanks for the verification JR

 

No problem. Keep me posted and send me a log if it does it during normal operation. If it's sending erroneous data here and there then I will limit it to keep that out.

 

Alright sounds good. I'll hit the freeway later today and data log during a constant cruise.

 

you sir need a faster computer! god that would drive me crazy.

 

My computer is fast. Nothing wrong with it. That has nothing to do with my computer.
I just turned down my datalogging speed

Before I went out to datalog Neptune had a new version so i updated it. Dont know if JR already made new adjustments or not but the freeway cruise seemed to be better. More solid numbers only time it read all weird was when there was no load which you should see at the beginning of the video.

I'll try city driving tommorow again just for my own reference.

 

Na, didn't adjust anything with that yet. Keep me posted. You do need to turn up the speed!

 

Speed bumped up. New vid later

 

im just saying, my gauges read almost as fast as its happening.

 

Alright so I did a little city datalog. Its not horrible it just annoys me.
My laptop is daily used for school also, so of course it wont be as fast.

That looks like it's working fine, although because it's so slow it's hard to tell.

 

I up the data logging speed almost to its max. Its always been this way ever since I purchased NepTune.

 

Then your computer must be really really slow or you don't have the right drivers for the laptop installed. Even my 2000 model year P4 1.7 datalogs better than that.

 

My computer works fine like any other. But we'll see. Maybe a little update might not hurt. I purchased it right before windows 7 came out. Only a year ago

 

It should be running a lot faster, then.

 

are you running any larger background programs? I've never had to close any programs from the task manager but maybe you have something running that doesnt need to be running.

tried disk defrag? cleanup? anti-virus?

 

I actually uninstalled a lot of programs I do not use on my laptop. Its running alot faster now. I will upload just to confirm later. Accidentally deleted my wideband usb adapter so have to reinstall it again.
