Has anyone tried this? It looks interesting. I now have a goPro, so I can video the gauges. If this thing is accurate, that could be a valuable tuning tool. A/F gauge

I like it. I have the mtx-l digital and sometimes it sweeps thru the numbers so fast cant get a positive read. With the needle i think you might get a better idea if its sweeping quickly. yes the digital reads fast, thats the point, I can see a misfire on my gauge.

I have been happy with innovate's products. If this is something for the coupe I would recommend two of them. I was really surprised how different the two banks on my car are when I added a second sensor. With 8 carbs you can dial that in pretty good if you have the info.

The two banks might not have different AFR, you might have an exhaust leak on the side that reads lean. Or you might have one wideband that is reading off. You can swap the sensors side to side to see if the problem follows the sensor or stays with the side. If it stays with the side then I'd bet you have a small exhaust leak. We see this all the time on the dyno and I've never found the issue to be with the engine. It is always with the sensors or the exhuast system. Most engines just don't run richer or leaner on one side than the other unless the induction system is really strange.

I could see different bank to bank AFR on a long ram as it basically turns the engine into two four cylinder engines. Getting 2 carbs to make identical fuel curves on what is effectively 2 similar but separate engines would be quite a challenge.
I don't think the balance tube would make any difference to speak of on this as far as AFR is concerned at least above idle.
Kevin Yep you would be correct, but a single plane intake only needs 1 o2 sensor.

This would be for my coupe. The 2 plenums on the cross ram intake are not connected, so 2 meters would be a good idea.

Kevin Sorry Kevin, confusion on my part lol no harm no foul Lol. No problem, I thought I was quoting BBM who was talking about a long ram setup when it was actually Bad340fish. He said he was seeing a difference bank to bank so now I'm curious what his setup is. Kevin

Kevin Yep you would be correct, but a single plane intake only needs 1 o2 sensor. Apparently I thought I was quoting BBM's post. Oops.. What kind of induction is Bad340fish running? Kevin Single plane indy intake for W2 heads. Its got lots of camshaft so it has a lot of reversion which makes a mess of the intake at low flow scenarios. Its port fuel injected so the fuel part is consistent but the airflow will cause variances. I knew that happened and have seen several cases of it but I didn't realize it would be so much. The amount of fuel feeding the two banks can be very different at low rpm and low load. Like I said before once you get tipped into the throttle and the RPM comes up it all falls into line. Joel, they make a nice digital gauge that runs two sensors but that may not be the look you want with your coupe.

I went ahead and ordered a pair of MTX-L. Thanks for all the help!
