nothing that's useful. Its a russian forum.

I did grab their utility and ran it and got it connected and datalogging. I got a nice graph for the o2 sensor switching. The problem is the entire program is in russian. You have to build a cable to do this, its not very expensive but it requires some work to make it happen.

I had a cable built to talk to the ECU with my laptop for a whole other project I was working on.

Im not a software engineer but I did find a way to disassemble their program and found all the strings. I'm trying to find a way to translate their program and recompile it.

Re: CA SMOG, HIGH NOx

Man... I traveled back in time almost 10 years and read all 15 pages of this thread and thought for sure there'd be a solution...

Don't get me wrong, there is so much good info here. I haven't looked too much into my XJ yet because I wanted to read as much as I could.

I'll report back if/when I pass.

godspeed my friend!

I'm no tuner but in my case it seems like if i could just fatten up the fuel curve when its under load, and get the mixture a little richer, i'd have no issues passing.

Re: CA SMOG, HIGH NOx

When you have something to report, PLEASE start a new thread rather than continue to bump this relic. In case you fail, make sure you post all of your smog results, the year of your XJ and other relevant factors.
