2015 Honda Civic RR installation help

Post by Ebegrowi »

So this may be an odd problem but, I recently installed the Maestro RR with the Pioneer DMH-1500NEX. Before installation the factory fuel economy (on the small screen in the upper right of the dashboard) meter was telling me I was averaging about 24-27 MPG, after I installed the RR it now says I am averaging 15-17 MPG and it can go up to 20 if I have the econ button on. I don't have a factory amplifier and not retaining OEM bluetooth and on the instructions provided by idatalink it says I am supposed to hook up the "B" connector to my car, and on my Civic the B connector does not fit any of the factory harnesses but, the "A" connector fits so I hooked that up instead. Could this be the problem? Also I am not getting any TPMS information on my head unit.

1- With regards to the MPG inaccuracy, The MID screen is getting its information directly from the vehicle over the databus network, the maestro just looks and reads the data. Because we just read data the Maestro isn't going to be outputting any of that information to the vehicles MID screen.
2- Connector A vs Connector B, in some cases (rare) you will be using the 12 pin connector instead of the 14 pin connector this again will have no impact on the vehicles data.
3- With the HO2 platform TPMS is not a supported feature hence the reason you dont have it on your headunit.

Ok so then what you’re saying if I understand correctly is that the Maestro doesn’t have anything to do with the MPG drop right? It’s just weird to me that there’s such a huge MPG drop after installing an aftermarket radio

Also the iMID screen on the dash reads the DMH-1500 as an AUX input/Extension. I’m not sure if this is normal or not, this is my first DIY radio install
