logo for software

I am looking for 2 logos for two software applications. The name of the software applications will be "TwinEngine" and "TwinTurbo". I am looking for a logo that looks like a speedometer in 3D. I've already found something online (see attached), and would like to develop this concept further. The logo should convey speed and innovation. The speedometer should have 6 "blocks" with rounded edges, and the speed needle pointing towards the point between the 4th and 5th blocks. For TwinEngine, the first 4 blocks should be solid, while the 5th and 6th block should be empty with just outlined shapes. For TwinTurbo, it should be the opposite, i.e. the first 4 blocks should just be outlined shapes, while the 5th and 6th blocks should be solid. The logos should be presented in black and white only. I'm looking forward to seeing the design concepts the freelancer will create.
