Good luck!
I currently get about 28 city, 33 highway. I have gotten it as high as 36 highway before. This is a lot better than the car is rated for.

The ECU only has one VSS output. I am looking for another way to get the VSS signal.

Edit: I have confirmed pin B10 on the ECU is not giving me the VSS signal I need. Further research said my model of prelude has a mechanical VSS. Not sure if that effects what I am doing here. Something online said pin B16 would also work for VSS, although the schematics says that is the crankshaft sensor ground. I tried it. I got a reading of something but it was not speed.

I am trying to find the VSS sensor on the engine so I could hook it up direct.
