Settings not storing

[Simon Vez]

Hi, I have an STI V4 G1. I tried with the LCD display in the car, I tried with the laptop, and my settings are not kept when I turn the ignition key off. Do I need to connect any cable to have it like it will be in 'write mode' ? thanks

You need to perform a store after making changes. To do this on the remote hold both adjust keys down whilst on the store menu.

Sounds like you are doing every thing correct. I have never seen this in the past. I suspect we will need to get the ECU back.

I already sent it to LINK. They said it was fine It looks like a car radio when you dont plug the power correctly. It runs good but will flush your settings when you turn the ignition key off...

A really long shot but make sure your power and signal grounds are in good shape. The way the memory works does not require power to be maintained once a store has been performed. No reason for it to be any different in the car than on the bench as far as the memory goes. The settings change even with out running the engine?

As long as I dont turn off the ignition key off, the settings remain. Correct me if Im wrong here: To STORE the settings, its basic flash to EPROM right ? (Electrical Programable Read Only Memory) So it needs a certain amount of electrical power to write on the EPROM. You might be right about the grounds. I will go buy 20 feet of 2.0Sq/mm wire and will re-run all 4 grounds to the engine block. MAybe I have poor grounds and its not generating enough power to write to the EPROM? Its still odd as why it keeps the settings.. meaning it stored it somewhere, but goes away when ignition key is turned off. Anyway, I will try the grounds. Here is something interesting at the bottom of the page: http://www.linkecu.com/support/documentation/g1-engine-management-documentation/MY96Manual
