Hey guys after I swapped the diff out I got a fault code, I never got to read it but now I have to smog the car and it gave me a code of 090500 or 90500 (speed sensor). I have replaced the sensor with a new one and it still comes up (CEL), the guy reset it yesterday and it came back on 5 miles down the road... I need to pass this smog tomorrow, what can I do to solve this problem other than swapping back the old diff???... __________________ 2LT Rodriguez CA ARNG

Do you have an E30 speed sensor or a ti sensor? I believe you need the E30 sensor if you use an E30 diff. __________________ ~Dave~

I even bought a z3 sensor and nothing... the thing is that it does read speed and the difference from nav gps speed to speedo is 1-2 mph, so it is actually reading correctly!... __________________ 2LT Rodriguez CA ARNG

Luis;
I did the same swap, and used the Ti sensor, as the wiring was not correct to use the e30 sensor. I did not get any CEL, but being OBD1, I suspect it isn't an issue...

Hmm, I was just going off of what Jesse said in the Diff compatibility thread. Quote: | Originally Posted by cooljess76 The setup I'm running and I highly recommend is an e24 3.46 LSD with an e30 cover, e30 halfshafts, e30 output flanges and an e30 speed sensor...
...And the e30 speed sensor is plug and play with the 318ti connector(at least mine was), there's different styles of connectors, you need the one that is round on one side and square on the other and it needs to be the same length as the one that originally came out of the diff that you're going to be using. | __________________ ~Dave~

My diff came off a 87 325is, it's a 2.93 ratio. The speed sensor from the donor was similar sized, but the connections were totally different. __________________ James 95 active w/leather interior and sport interior conversion, Vaders, full M-Tech exterior conversion.

When i did my swap i put in the E30 or E24 speed sensor in it. I forgot which car the diff came out of, its a 3.25 LSD medium case. I spliced the speed sensor into the wiring and had no issues. Didn't try using the ti's speed sensor since i always read you had to use what the diff came out of. __________________

Check the physical lengths of the two sensors. They should be the same.
It may 'work' (make the speedo show a speed) but the DME is not satisfied.
In the M Roadster diff, the M roadster sensor works flawlessly, and has the same connection on it.
If you can get one of those (and it happens to fit the E30 cover) you should be set. If it doesn't fit (due to length or mounting) you may want to consider changing the rear cover to the M Roadster cover and then use the M Roadster sensor.
Caveat: If the sheet metal ring the sensor 'reads' is different between the stock E30 and the MZ3 you may STILL have problems... | | | | | 08-05-2010, 02:56 AM | #9 | | Senior Member Join Date: Sep 2008 Location: Central Florida Posts: 678 |
Well...
Swapped the diff, got it smogged, and swapped back again!!!... My arms are hurting like a B...tch!... fun Stuff!
I think I might try the Z3 cover, right now it has the original e30 cover with a z3 sensor... maybe I just have to get the Mroadster cover+sensor... later project though, right now I have an AC compressor to change this weekend, any tips???... __________________ 2LT Rodriguez CA ARNG
