ok so i was reading some old posts and read that the st205 electronics read kilometers, which of course we all know. but i never grasped the fact that our odometers will change from miles to km (why cant the US be simple like the rest of the world)
i use my trip mileage a lot. will i need one of these signal converters to have it work like stock usdm? http://www.ebay.co.uk/itm/TOYOTA-SPEEDO-CO...les_CarParts_SM -------------------- QUOTE (Azncelica @ Mar 4, 2012 - 11:43 PM)  I started with what I know to do, I swap engine into my car, I knew it was too much work to make it a AWD. I kept it FWD. Went to take a crack at doing the wiring conversion. Than, I realize, shoot, this is out of my league. |

The speedometer gets signal from a heat driven sensor on the trans. Since most people reuse their S54, it's exactly the same sensor as before. The E153 works perfectly, as does the sensor on my JDM S54. The speedo has no problem at all.

Although I may be wrong. either way my question is about the odometer itself, not speed. Idk if they run from the same signal but either way that signal goes through the ECU so I would assume it gets processed as KM -------------------- QUOTE (Azncelica @ Mar 4, 2012 - 11:43 PM) I started with what I know to do, I swap engine into my car, I knew it was too much work to make it a AWD.

They all get the same signal from the transmission, just the speedometer has different electronics on the board for anything mph vs kph. It just converts the incoming signal to a different output signal for either of the two. If you swap a kph speedometer into your cluster, it will still read the proper kms. If you leave you mph gauge in there, it will read the proper mileage. The odometer is on the speedometer so it uses the same circuitry which means it will read fine if you have your mph gauge in the cluster.

only mr2s, will have that problem since 91-92 mr2 came mechanical speedos, and most s54s r electronic from 93+
our cars luckly 94-99 came equipped and a lot smarter than that lol. |
