best spot for wideband sensor?

[RICAN]

I am planing to go with 100 shot in a few months. so my is on which test pipe is best to install the sensor for the wideband!!...or do i need two sensor(one for each test pipe)for the readings to be accurate!!...i apologize if this has been covered already i search and didn't find anything!!...

[RICAN]

no body knows?

Either as far forward as you can.

I'm not familiar with tuning these cars but on others, richening or leaning the car out didn't give you an option to pick which side of the motor you wanted. Each injector got the same pulse width so they'd all flow equally. So it doesn't matter which side you pick.

But the car already has wide bands. When tuning, the tuner will watch those and tune accordingly. I don't know about you but watching gauges during a drag race or when NO2 is flowing is not on my mind. I'll feel or hear something blow before my eyes have time to look over and see the A/F gauge reading incorrectly. There really is no need for a A/F gauge. But a wideband is needed when tuning and when doing a run I only watch knock tables on the computer. After the runs over and if it went good, I'll check the fuel readings and lean it out or richen it up from what I'm seeing. But again your car will show the tuner that from your front most stock widebands.

on my other cars(srt) i always put them at least 5 inches from the turbo hot side(exhaust housing) for the most accurate reading and this was told do me the the company that makes the tunes for that car.

i know the tuner will use the factory wideband...but for my peace of mind i like to monitor the A/F and knock every day or chance i get to go to the track but i got a scan gauge that reads short time and long time know live..so in not worry bout how to read the know i got that covered .....for my experience on turbo cars anything time is was really cold outside it will boost a little more because the temperature and the density of the air....and the reason i ask bout 2 sensors for accurate reading!!is because lets say i install the sensor on the left side test pipe and one of the injectors on the right side is not working right when im wide open throttle ..it will be leaner on one side more then the other!!...that's why i ask to see if there a wide band out there that has 2 sensors and one combine accurate reading

That's where I put mine. You kill the sensor fast but if you don't want to uninstalled and plug the hole all the time just leave it and replace the $69 sensor every now and again.

I'd hope if an injector goes your dash will tell you faster then your gauge will as you sit there going "that doesn't look right, wonder whats going on?" Not to mention the huge drop in power you'll feel before anything.

If you're going to do it, do it. Install as close as possible but within the collector and not in an individual runner.

There's going to be a slight variation in fueling between the banks. Uprev only allows you to adjust fueling globally, so you just have to tune for the leanest side. It's not such a difference that you'll ever notice. One of the things Ecutek "has" is the ability to tune fueling per bank, so if you're on the fence about software that might be a concern.

I would assume datalogging the OEM O2 sensors will show you which side runs a little leaner and you could put your wideband in that test pipe.

yea my exhaust is a true dual so is individual for each side all the way back..lol...

Thanks for the info chuck!........i don't know bout what software I'm goin with I really wanted to try ecutek but dynotronics is the only around me that does ecutek and I hear lot of ppl complain bout them!!...and I do want to get my car tune on a dyno not a etune or nothing like that!

I don't remember with the Tuner Version of Uprev, I'm sure it was there.

But with the Pro Tuner, it is possible to tune the fuel on every single injector.

Then the VVEL is now accessible to every Pro Tuner Cable activated Not in closed beta anymore, no idea about the Tuner version thought.
Because some setting aren't accessible with the Tuner version
