Many of you guys have done the Motech DIY beta kit. I am finally driving my ride and working out bugs. I added a Kenwood DMX905s 2din head for both tunes and digital gauges with the iDatalink Maestro ADS-MRR Interface Module. I thought the iData module to the Kenwood would allow the 2015 steering wheel swap with radio buttons to link but found that their module still goes through my 2009 TIPM so I'll work those issues out later. I'm currently using the accuracy of the iData speedometer gauge on the Kenwood as my Jeep OEM speedometer is reading about 5 to10 MPH low depending on speed. Robbie recomended the AEV ProCal but the $170 dipswitch OBD plugin doesn't appeal. Has anyone else dealt with this particular issue?
