Those having spark related issues it's more than likely due to this table not accessible in HPTuners without adding it yourself in user defined parameters.

I figured that existed. I saw at e55 that I wasnt getting all the spark and did a little math. It lines up with that table pretty well. Good find.

the spark related issue Doug was speaking of was in regards to logging the flex spark. No pid is available in hp.

The Flex advance PID is there, HPT just doesn't have it added to their scanner.

I figured as much. Anyone have the address to it? Can the user add custom pids to the scanner? I have never tried it with hp. I did it with torque and my data viewer software in the past

I need a favor from someone. I have so far had some great luck getting the system segment to function in the tahoe file. However I ran into a minor error with data alignment. I need someone with EFI live to mod the ac turn on delay vs iat table in the Tahoe file and save it so I can see it as a bin. I need to reverse engineer it to find where the data actually resides. I don't have have access to the table in hp tuners OR if someone is kind enough to give me the address to this parameter that would be extremely helpful. I also need this for an fbody file. I can provide the BIN files so we continue working with the same files so its easier for me. Any takers? Either post or PM me. I am like a ball hair away from being able to test this in my car.

I appreciate it Pete but you set me straight via email. I was able to get it to look pretty in EFILive but it bricked the ecu. Back to the drawing board!

Logging wise? No. Tune wise? Yes, it functions correctly via the values I input. I didnt try much with the logging though, been too busy messing with the segments

If you decide you don't want TCS but want to retain cruise and abs like me, I suggest this. I have a non-tcs abs module/pump.Obviously its for a 3 channel car vs my 4 channel. On the pinouts, pin 4 needs to be moved to pin 3. Other than that, let the car read off the rear left wheel speed sensor as its main sensor (pin 22 and 23). On a non-tcs car this is where the car gets its signal from the diff mounted speed sensor. Run a single line to a splitter at the differential and connect your brake lines. Done. One of my intermediate brake lines burst recently which has prompted me to replace them anyway So i can try this out and see what happens.Should work I would think. This will remove and shut down the tcs and service vehicle light.

Also for those with a blinking check gauges light, use a different file, that's likely the cause. And if you have that annoying change oil light, if you use your tech2, nano or whatever, you can reset the oil life to 100 and eliminate that light as well (it eventually goes off on its own but its takes an annoyingly long time)

Sorry to bump the thread from the deads, but. Do you still have U1000 no-communication code with that wiring? My ABS module fall slowly to his death and I might be give a try if it's work that good.
