I bought the one listed above for My 440 / 500 Stroker. I never set up a Holley before and it helped greatly as mentioned to see which direction I was taking things. It has since stopped working . If it was still alive I would have welded a bung and used it for tuning on my 340 Ragtop. Too much money for the short time I got out of it.
I still suspect a vacuum leak on my 340 since rebuild as it runs lean and I have to run half choked until really warmed up. I am soon the add a Air gap intake and then final tune carb. I have an AVS (originally on motor) and a Eddy 625 ABS (currently on motor) Thought carb needed rebuilding from sitting but ran the same so I rebuilt the Eddy and got the same results.

I see. Definately good to track effect of changes.
No way to pinpoint what failed?

I think the current Innovate products also use the LSU4.9 sensor. Pretty sure that's what came with my new LM2. The connector in the phot shure looks the same.
Also pretty sure one advantage of the Innovate gages is that they can be also used for logging.
So there's a couple things to check into.
For a while Innovate had a "pocket logger" but they may have dropped it.
Not sure if Innovate's stuff is quite as affordable but their LM1, auxbox and LM2 are what I've been using.
