Tach sensor 2009 Kia Spectra

Question

2009 Kia Spectra. THAR-ONE-KHY1. I need to know which wire to connect the tach signal to. Yes, in the Wire Colour diagram it does tell me which wire on the ECM, but no-where can I find which wire on the EVO-one it must be connected to. I have by-passed it currently using programmable option 20.2, but the start quality is pathetic; in cold temperatures it requires more crank time, causing excessive starter drag in warmer conditions. Adjust for warm temperatures and the crank is in-sufficient for the cold mornings. Advice for me?

Answer 1

Hello,

The evo-one does not have a tach wire.

Option 20.2 has been set on my personal vehicle for years now wthout any adjustment needed based on climate. 2008 pontive vibe is my personal vehicle with 20.2. I live were the temperature goes from +35c to -35C.

Tachless is based off of battery voltage, if you are having poor cranking time you may wanna get the charging/battery system checked.

Otherwise you could try 20.4 or adjust the tachless setting as mentioned.

Best regards.
