Update: motor is in and running great. Had to shim my custom built e30 3.15 LSD down about 5/16" to allow for the 6 bolt M3 flange to clear the top of the rear subframe, but other than that everything went in well. Got a custom exhaust built and installed this weekend so now I can actually drive it without scaring the neighbors!
The car drives awesome and was well worth all the effort. Back end gets loose easily even with 225 slicks. This thing is a drifting monster! As expected the ASC light is on so I will have to pull the bulb in the cluster. I cleared all the CEL codes but keep getting a p0500 code that says it is the speed sensor.
I pulled all the wheels and tested each wheel speed sensor and they all ohmed out to be good. My abs light is on too! I'm pretty sure something other than a wheel sensor is wrong as the abs light is on at startup and would go out until I start moving if it was. I put an e36 speed sensor in the e30 diff and my speedometer is working great. When I hook up my obd2 live reader though I am not getting any speed in the dash command app so I am wondering if I need to connect some other wire somewhere to enable this and fix the speed sensor issue and also fix the abs.
Any thoughts on the matter would be greatly appreciated. |
