Title: Tech 2 spares
Post by: carrera on 13 May 2026, 08:34:39 AM
I have made a couple of investments in Tech 2 spares in the past couple of weeks

Firstly, one of the Tech2 > OBD connector adapters lost its earth connection. The adapter also did not want to slide all the way in so I decided to get a new one, rather than potentially cause harm to either the main cable or CANDI cable. It's coming from China

Then, having sucessfully used the Tech 2 for key coding, I wanted to get SPS programming access. When I tried in car I received an error message as follows > Address Error: Processor Fault

That's not good, especially as I probably need it to code the replacement pump to the 2.2. TiD

Having referred to this thread https://www.trionictuning.com/forum/viewtopic.php?t=2985 I have ordered another Tech 2 card. I do have the ability to write to the PCMCIA cards, but it's as cheap to buy a programmed card. I could have rewritten the existing 148.000 card, but didn't want to, as I was concerned that the rewrite process might kill it & don't want to lose all functionality until I have the spare

Having tried to use the Tech 2 recently with external power supply in attempt to survive an engine start (it didn't work) I have concluded that my Tech 2, a generous donation from Jeff The Chef, is a clone. A good one though.

It's possible that the rewrite will work fine, or that the fault is not with the card, so I will post an update when it arrives

Where did you connect the external power? On a clone it may only work if connected the point where the cable connects to the CANDI, and not directly to the Tech2 head unit.

I connected the power straight into the head unit, when CANDI was attached. 

I just looked at the CANDI unit & can't see any other place that power could be applied ?
