cable to hook up laptop to ECU (if you want to borrow)


Recommended Posts

Hi guys,

I have build a serial port cable that plugs into the yellow diagnostic plug (early - mid 90s models).

All you need is a laptop with a serial port. I tried it on a 6S and 1S ECU, and I can get and log the following:

TPS position, AFM voltage, ignition timing, revs, load, MAP, O2 voltage, coolant temp, boost solenoid duty ...

I used some free software (can't remember the name, JECscan I think it was). havn't tried it with

Evoscan, cause I don't have it.

If anyone wants to borrow it to get your car sorted, PM me.

I am in Dunedin.


P.S. I can't build you one, cause I'm using a TTL to RS232 unit from work (I'm lazy).

Also, you need your own laptop with serial port, I don't have one (borrowed one from work).
