logger or wideband?

[99 gst spyder]

all the mod on my list and panning to upgrade my fuels with 550 cc inj., walbro 190lph , and safc neo, and i'm just wondering should i get a wideband first or should i get a logger?
i know it's best if i have both but short on cash now and will get the second one there after.

thanks

Logger.

The S-AFC will be pointless unless you know what your engine is doing. And yes, the wideband would be nice, but a logger will tell you so much more.

Well they pretty much compliment each other.

I wouldnt even get the Neo without the wideband. What good is a tuning device if youre "blind" tuning? Plus you cant even tune really without the logger to log it all.

I would have gotten the logger before any of that anyways.

Id save up and get it all at the same time or else its pretty much all just decoration.
Just my $.02 !

If you cant afford both get the logger first, you can at least see what your car is doing, plus you can see fuel trims to see what you need for fuel, either more or less

The general idea here is correct, the logger will give you TONS more information than the wideband will, but the wideband is still nice to have, which is why i have both

I'd personally want the logger, Wideband, then AFC in that order so while tuning you know how the fuel and timing etc are changing.

If you have a laptop already get the EvoScan software and cable for logging. It works on your 99 plastic ECU, cost less than a Pocketlogger, and has more features. If you don't have a laptop already then get a Pocketlogger setup.

Depends on the logger, if it's anything like the one I used before I'd do wideband.

Exactly, its better to see what is going on before you attempt a tune, than to tune blindly without any monitoring.

so for me inorder to use the logger or a wideband is to have a connection from my ecu to a laptop to see/ or tune my dsm? correct me if i'm wrong here b/c never use these device before.....

How can anyone recommend a logger before a wideband? Sure, the logger tells you a bunch of cool things which can be really useful for diagnosis and fine tuning, but the wideband tells you the one thing that is far and away the most important while tuning. Give me a wideband and I'll have the tune 95% right in two pulls, then it can be touched up with the logger later. Try to do it with the logger and not the wideband and you're in for some blind guess work.

A logger requires a connection between the ECU and a laptop/Palm/smart phone. This will be achieved by an adapter that will plug into your OBDII port (under your dash in the area of your right knee while in the drivers seat). This will have an output in the form of a serial port. Then you'll run a cable from that to your device (with another conversion possibly - to USB). Then the software will interface with your ECU and you'll be able to see what it's seeing. If your logger is also a tuner (i.e. DSMlink), then you'll also be able to make changes and tune. I'm not sure what EvoScan is though. If not, then the logger is just a viewing device.

The wideband can integrate into some loggers, but can also be used as a standalone device (either with a gauge or LCD output).

 

[jcurcillo]

There are many different wide band setups as well as different logger setups. You could go with a gauge type wide band like the AEM that will give you live readings of you Air/Fuel. Or you can get one that will log the info on a laptop which you can read at a later time on a graph.

Logger are designed much like the last one to capture the info and then refer to it on a graph. There are Palm Loggers, much like the Pocketlogger, and computer based loggers like the EvoScan. The Pocketlogger is less expesive because it runs on a less expensive device, the Palm PDA. However, if you already have a laptop the EvoScan is less expensive and includes more feature. The EvoScan also includes the option of hooking up a wide band to your laptop to log air/fuel (requires additional equipment).

Well, some people (like you) are either smarter or have been around cars and tuning longer. I can't say I know of many people who could do this, so more power to you.

That Evoscan thing sounds pretty cool. I'd definitely lean towards that if you have a laptop. Being able to log your wideband along with everything else is pure win. If you don't mind looking back and forth, or you have easy access to a dyno, the Palm based loggers are great because they don't take up space and annoy your passenger/tuning helper. And if you have to leave it in the car, it's easy to stash in the glovebox or arm rest so it doesn't get stolen. That isn't really an option with a lap top.

 

[jcurcillo]

Wide band is the easy way out, but it tends to cost more. If you can get your car on a wide band and tune for ideal A/F mixture, much like they would do on a dyno tune, your done. However, not all of use have the cash to through into a wide band setup. Plus you can't fine tune with it. Wide band is good for wide open thottle power while the ecu is in open loop, but you can't tune for daily driving. You need to know things such as knock, fuel trims, and timing advance. This why a data logger is good for street tuners.

If you want to know about EvoScan go to EvoScan OBDII Mitsubishi MUTII DataLogger Scantool
I just got one and it is great. Not to mention you may be able to flash a 98-99 plastic ECU in the future. Much like DsmLink. It is still in development.
