Quick shipping, seems great.
So far so good. Nice to have a single gauge that shows ethanol %, AFR/Lambda, temp, and pressure.

Does not bring a 10 bar fuel pressure sensor
A lot of stuff was apparently missing from my kit I didn’t notice it till now when Ive finally got the time to install it.It works but I’d say check all the contents a lot of stuff could be missing.Installation was rather difficult but not too bad.For the money I’d rather just go for a E85 gauge for less. A lot do the functions of this gauge require extra stuff either I’m missing or just gotta pay even more for it which makes this insanely expensive for what it comes with.Innovate does make good gauges and is built well just keep aware of the other issues that can come up. Foment is really lose in most gauge pods I had to use double sided tape to keep it in place.

Pretty nice gauge!
Seems to be working pretty well. The pressure gauge seems to jump around more than I would like (10psi changes at times) making it hard to get a handle on actual pressures. Could be a bubble in front of the sensor or something? It's installed in my fuel distribution block.I wish it had peak recall function.
