Solution: Speedo calibration, details inside Options

[snapshotgt]

It looks like my speedo is reading on the high side. I am using the e153 tranny out of a 99 Solara. I also have bilstein struts, tein springs and 7th gen GTS wheels with 205/50/16 tires.

Four sources of evidence of possibly reading high:

1.) GPS is reading ~10mph slower

2.) OBDII reader from the solara is reading ~5mph slower

3.) I can be crawling at a snails pace and it reads obviously high

4.) When slowing down to a stop, needle can make un-flowing drops down in speed, does not look very accurate.



Please post your thoughts and suggestions. I'm looking to fix this and get it as accurate as possible. Anyone running with a e153 tranny swap please post your experience. Thanks-

Here's what I got back from Healtech this morning:

Hello Scott,

Thank you for your email.

Most likely one of our SH model will work. Before ordering, the best would
be to check the sensor with a meter.

A 2-wire sensor can be either a ground switch (reed) or inductive pickup
coil type.
To check this, please proceed as follows:
- Disconnect the 2-pole connector of the speed sensor.
- Measure the resistance on the two pins of the speed sensor.
It is a ground switch speed sensor if the resistance is either infinitive,
or zero Ohm.
If the resistance is more than 100 Ohm but less than 3 KOhm, it is an
inductive sensor.

Please let me know your findings.

Kind Regards,
/Norbert
