This works great and gives you piece of mind after you fix your engine issues. You can customize it to show about anything going on with your car.

The product is okay. Looks sharp. The mph is not accurate though. When you get over 50 mph, It's off by about 3 mph.

got to make sure its centered for driver if its on a angle might not be able tosee but good product and works well so far. I wish i could make one setting bigger like i bought it to see my turbo pressure i wish there was a mode where i could just make that number big on the screen

Works for the most part. However, the RPM display on this screen layout is simply wrong. It's not even that the device can't read the RPM correctly, it just isn't displayed right. You also cannot adjust the redline, though you can set an RPM alarm that is just annoying... What a shame, because it seemed good aside from those glaring issues.

I got this mostly to monitor transmition oil temp on my 2021 promaster campervan. It works great. Now that is the only thing I look at for speed and rpm. Easily can switch from kmph to mph. And the level meter is great to help find a level parking spot

This unit plugs into the ODB (diagnostic port) on cars made in the last few decades and gives you access to information that is not displayed on your dashboard but which you would like to have displayed. It worked perfectly well for many things for me but I specifically wanted to monitor the transmission fluid temperature on our Honda Ridgeline. It claimed to do that and it probably will for some cars. The problem is that some variables, transmission temperature is one, are not reported in a standard fashion from brand to brand, model to model. So this unit was not looking for transmission temperature in the place where Honda reports it and the user cannot change where thus unit looks. So I had to return it. But it seems to work just fine for the variables most useres would be interested in and you might be perfectly happy with one of these.

I enjoyed the ACECAR heads-up display in my ‘18 TTrs for about 20 days. It helps when your eyes can watch the road and keep a peripheral eye on the RPMs. Then suddenly it would shut off on its own. I did the troubleshooting but the display failed more consistently as I drove. No sequence of time or configuration helped. Finally gave up on a recent road trip of 250 miles where the display stopped working around 50 times. I would have been really POed if it started to fail after 30 days.

Speedometer and tach stopped working on my F150, was able to place this over the speedometer and still be able to read my speed. Also reads/displays most information available by the OBD2 system, and can read DTC codes (Check engine lights). The ambient lights on the side are able to be customized to change colors with speed, rpm, or engine coolant temperature, or a solid color of your choosing, I think it's kinda tacky looking, so i have it set to off in me review picture.
