Weird knock detection L98

[84Elky]

84Elky I am running S_AUJP V5, I did not see the update but will make the change tonight. I found the V5 did not have the ability to adjust the CAGS enable temperature so I manually entered it under emissions, it is located at 0x300. The grounding issue is a very real possibility and will be looked into this coming week where I have a few days off and will be replacing the clutch and flywheel for a single mass unit. This is for a 1990 Corvette with aluminum 113 heads and most of the spark table you see is stock.

One final note is that the provided tune has Highway mode enabled for spark and fuel running the engine significantly lean. From my best investigation over the past 2 weeks I do not believe this is actually spark knock but false knocks by a harmonic ( maybe the flywheel) or poor grounding as you suggested. Thank you for looking into it and I always appreciate the help.

Beginning with the initial version of S_AUJP (v4), 0x300-0x307 are not supported. They are in commented-out code deemed to not be necessary as it contained a lot of GM testing, so entering values for them in the cal is meaningless. Manual car will run the same with or without these items.

IF running S_AUJP v5, you are not using the v5 ADX. You are using the old AUJP v2 ADX which greatly limits reporting (ie - no In AE, In PE, DFCO, etc.)

I have attempted to use the V5 ADX when recording and result in garbage data. I will try with V6 in hopes it was just an error.

Not to sound arrogant but today I was provided a tune to try for a tuner and it had the CAGS enabled. I found this was not present on the V5 options so I switched back to $8D mask and found the address. I entered a new scalar under emissions and found the stock temp of 50C was showing for a value. Changed it to 151C and it has not triggered the 1-4 shift since. If it has been coded out of the new bin then you are correct in not needing it. to this point I have just used the stock tune and edited it under the V5 mask.

Elky I have tried following the provided instructions to carry over the calibrations from my current tune to the new bin provided but no mater what I do I get garbage out and the car will not idle. I then tried using the provided bin as sent and the car went into failure mode. For a 1990 Corvette is there a specific bin to start from and where have I gone wrong getting it to communicate?

You would start with the $8d bin you posted above in post #1 assuming that's a BIN with your latest "tune" (also called the BIN's Calibration).
Is that what you did and did you follow the instructions in the read me doc?
If so, which transfer Option did you use?
If you did something else, please describe exactly the procedure you used.
Please post the failing S_AUJP BIN and label it as such.
Tks.

After downloading the new zip from thirdgen.org I opened TunerPro and selected the new bin. I then loaded the new xdf and proceeded to use the difference tool to copy my latest .bin settings to the S_AUJP V6 -28. I checked the limit search to defined only and from there transferred over all the settings from 0018 through ve multiplier at 0821.

As I type I tried doint the same task with the $8D xdf loaded and noticed a significant difference in results. Is this how I should have done it under the $8D mask first?

For the ADX I simply selected the S_AUJP v6 as my definition file. Is there another step I have missed here too?

I also saw an S_AUJPN Bin file is the difference report showed nothing different, what would be the intended use of the two if different?

Tks for update. Not sure I fully understand, but please respond to these 2 items

Please also send me your current XDF file, not S_AUJP


Don't worry about the NVRAM 'N' version for now. You can't use it. Its calibration is the same as the regular version. Both have default values that should not be used because they may not provide the necessary "tune".

You can put a value into any S_AUJP BIN at 0x300-0x307 and they will not be used. This is why they are not in the S_AUJP XDF files. The code is commented out. However, 0x300-0x307 are used in the Factory version of AUJP, which is pre-S_AUJP.
