Aem uego best bang for the buck. Can find them new on ebay for like $150.

If you're just looking to straight up monitor AFR's while you're driving this x2 ^^^

When datalogging most of the time what gets logged and the actual reading are different. This is offset. If you're just looking to hook a gauge up and watch it then no worries.

Most programs I've used to datalog have a wideband offset scalar to make the logged afr match actual afr.

Thanks for the explanation. So would data logging only really be needed if I used email tunes??

I've had an AEM uego and the lc1. The AEM wires some wiring into a serial pin connection which you have to buy. The lc1 comes with everything, but you have to calibrate it every so often.

That's only if logging through a serial connection or serial to USB etc though.

Not really its useful for alot of things but honestly if youre doing mail order or email tunes there isn't much need to log.

For what you need just grab the aem. Make sure its for gasoline not e85 etc.

That is how I logged unless there is some logging tool that will accept a 0-5v wire connection. The LC1 connection goes into a plug that goes serial too.

If it is for email tunes, then yes he would need to log A/f. The point of email tunes is to send the files back and forth. For basic off the shelf tunes, he would not need to log.

Please don't listen to this.

Lol. I want one just so my dash looks cool.

I'd love to hear why....

It could be a wording issue. So I'll see what you have to say before explaining.

You have to datalog afr's for tuning. That's one of if not the most important parameter to datalog when tuning.

I have no clue what kind of car he has, whats done to it, or what software he or the tuner is using so I'm being very general. All the Honda stuff is capable of logging 0-5v as is hptuners and sniper, pretty much everything that's not a handheld tuning device is capable of logging 0-5v input.

The reason I say mail order and email tunes really don't need to log is simply because that's a/f tuning with no known outcome ie: instant track/dyno results based on the change. So I consider them start up and get to a tuner tunes with no hard driving. Of coarse every car is different and different car cliques (dsm, Honda, gmEFI) have different thoughts of mail order tunes. I think some can get by with them and some can't but my point is most people relying on mail order or email tunes usually aren't modded enough to need logs to correct small afr needs (without known outcome). I have done plenty of email tuning for Honda folks back in 2005 ish when not everybody knew what an emulator and chip burner was, but most were NA.

Logging is needed to get a desired afr when email tuning what I should have said is email tuning shouldn't be your sole solution if possible so dont get too worked up about logging for email tunes.

I don't plan on using a can tune, but ill probably go with one that I can anyways just in case I might need to do so at one point or another.

^^ it's an 02 HD F150 with bolt ons and a 4lb lower

NGK AFX...end thread

My car is heavily modded and will be getting an e-mail tune, you better believe I will be datalogging afr's. That's a must regardless of the level of mods.

I totally agree with you there. My point is only that email/mail order isn't tuning. It might get you good enough but I don't advise it for anything other than bolt on NA cars. You can't just say OK goal is 13.2 afr at wot and believe that is what the car wants with nothing to back it up.

So therefore he has no reason to use the feature on the wb and doesnt need it? You sure are giving some bad info based on your own opinions.
