What widebands you guys running??
 

I wanna add widebands to the boat, been looking at the FAST system... What else is there also need longer wire for o2 sensors to reach ....

What's out there?

I use innovate LC-1s. Have worked well for me, and they have several guages if you want the readout. http://www.innovatemotorsports.com/products/MTS.php

What did you do about getting the length of wire to the back of the boat for the sensors?

make a wiring harness... it's just an extension cut n paste lol

I have the NGK powerdex AFX. Its not a very feature oriented unit. It simply reads the AFR. It has a bright, easy to read display, which I like. It's only a single channel, so if you desire to read both banks at once, you would want a dual channel unit.

I went with the NGK, as I like its simplicity, and only use it to dial in carbs on the water. Once carbs are dialed in, it gets disconnected and put back in the box. Its about half the cost of a F.A.S.T. unit, if price is a concern.

The NGK unit only has 13ft harness, which just barely reaches my dash. However, most of the time I am tuning on a boat, someone else is there with me, to write down the data. When I've been out on friends boats doing this with my NGK, I normally just sit in the backseat with a notepad, writing down the AFR's at specific throttle postions/rpm.

Fast does have a longer option harness option with one of their units

So you can just extend those wires without any reading issues? I wasn't sure if that messed up readings or not?

Cost isn't the biggest concern necessarily I just don't want to end up with $1000 unit that I don't need to something simple that works but I think I would like to monitor all the time because I had a lean condition ones that almost burned up an engine on me and if I would've saw it going when I could a lot out of throttle

I did the same. No issues...

If your going to run it full time, I'd just install an actual pair of AFR gauges. Also, are you running FULL dry exhaust? or wet?

I am dry all the way to the transom I mix right at the very end of the tailpipe

But not "thru" the transom? So you have a rubber connector with screw on tips on the boat right?

If so, you may find your o2 sensors will be short lived, due to the moisture in the system, mainly at idle.

I am running an "AEM" AFR gauge full time. Seems to work well. I extended my wires and it did not seem to effect anything. I am running a Bosch LSU 4.2 sensor but see they have a LSU 4.9 sensor now which they say is more accurate and durable.

maybe but if I gotta buy sensors sometimes no big deal, scott don't have many issues at all and he is mixing 10" after sensor I am 2 feet

Why mess with inaccurate AFR readings, what you need to do is spend a few months running up and down the lake pulling plugs. . But wait there's more! You don't need to do any of that if you just take your carbs to a good carb guy and spend a couple thousand, they'll be perfect! :-)

Seriously thou, I bet Mitch can get you a good price on a new one. I have a permanently mounted FAST. Two bank one per motor. You can't splice every brand but the fast is one that can be spliced as mentioned.

Mitch can get them?

I'm considering buying the autometer one Tim.
Going to install it permanently as well.

Autometer had a booth at the piston power show and the rep said, for 25 bucks, they will switch out the brushed trim ring for a chrome job to match my chrome and silver pro comp marine gauges. They don't offer a "marine" AFR gauge.

I wonder just how different the electronics are from brand to brand.

the really sharp guy,s send their carbs out to one of the super carb builders and they put their spark plugs in the box with the carbs to aid them with the 1000 dollar carb upgrade!

Mitch can get anything. I want a tonneau cover .. $150 cheaper than anywhere else.
btw, don`t try to extend a Autometer , their reading rely on the resistance of the wire to the 02.

He can't get a great deal on the widebands, decent but same as summit.. I gotta see what one I wanna get, he thinks he can get others cheaper but not sure how long it would take to get them..

I run an Automated NV series AFR gauge. I permanently mounted it in a single gauge pod with its own on/off switch on the inside of my fairing. I did extend the harness wires and I see no I'll effects because of it. The O2 sensor is mounted in my EMI long risers just above the manifold joint as to keep far away from moisture. I also have a second O2 mounted in same position on other pipe for my Holley EFI and it works perfectly there as well.

INNOVATE has a dual channel model now. One gauge with two O2 sensors - gauge shows both ratios. I have the single band unit. I love it. And If I do it again It will be the dual band. And it has outputs for your fuel injection system and data recording.

I think I was looking at that too...

I use an LM-1 and really like it. The best pricing for the LM-2 is Ebay. You want in dash or handheld?

Dash

I use the Innovate MTX-L mounted in the dash and use their optional cable extension to reach the sensor. The standard cable got close but not close enough. I run it full time just below the elbow. Works great. The logging capability is nice too.

I just picked up the AEM Failsafe.. Haven't gotten it installed yet..
It displays A/F as well as Vacuum / boost

You can map your A/F and set limits rich or lean that will activate a trigger you can configure however you want such as a warning light, waste gate, or rev limiter to protect your engine...

This is what I've done also. Although, it's easy enough to extend the wires yourself.

I ordered the fast system, with 22ft cables... I would love to put round gauge in but just don't have a place on mistress... The fast display I can put under the fairing

I run the NGK as well....but none can handle any water...
