And, I must have had a major brainfart.. I looked at old pics of my gauge cluster (key on), I do not see a CEL there..
My bad.. Again.

I will definitely look into that.
I also have question on knock intensity for you, but I need to finish this speech I am working on before I dig into the laptop for datalogs..

It's gotta be one or more grounds. Values would be hitting "0" if it was the power supply.
All values seem to be skyrocketing, some in sysnc, some on their own.

Found the culprit behind that weird log...
Today I checked everything and could not get the car to repeat the weirdness it had displayed.
Took a bunch of logs, did wiggle tests, did all I could, and no problems.
Then, I had an idea:
I plugged in my headphones, and the mic input to the laptop.
Bang. The problem came back in about 5 minutes.
Interference!
Over the past couple days, I built a couple of bolt on mics to listen for knock.
The idea was to plug the mic into the laptop via a two meter shielded cable, and use my headphones for listening.
I even downloaded a few programs (spectrum analyzers, etc) to play with the system.
Turns out, the setup interferes with MS big time.
Maybe I will use a second laptop (my wife's) to listen for knock.

Actually, it DID act funny. I had a bunch of high RPM misfires when this was happening.
I removed the microphone cable and the headphones altogether, and none of that is happening anymore.
On an unrelated note, I am making some progress..
Here is my AFR table:
Ignition Advance:
And this is what VE looks like so far:
I still have a an unintended table switching problem. The water in the tanks may be sloshing too hard under really heavy acceleration. (I test the car on an uphill section, to really load the engine, that may be making the sloshing worse)
I can see that by examining the ign advance in the logs.
Is there a quick way to check which table is active at any given time without taking my eyes off the road for too long?

On second thought, I will connect a LED to the water injection low water output to test my theory.
If that is not the case, I will have to make a manual switching system.
More stuff to play with!

I don't like the AFR table. What is your AFR at 130kPa? If it is more than 12...that's no good.
As for the table switching...there are indicators available in TS, called Fuel Tbl Sw and Spk Tbl Sw. They will go green when the switch is on.
