R33 GTR LinkG4+ engine knockings

Hi, I am experiencing engine knockings on my new maps on Link G4+ in Skyline r33 GTR. Can anybody check my maps and see what possible can be wrong over there?

I am using also my old maps that are ok without any knocking. My old maps are password protected so this is my problem. Cant see any settings over there. I dont have a good relationship with that tuning shop and iam strugling now with my new tuner to run new maps but we are experiencing this problems with knockings. ;/ My new tuner cant help it so far....

You need a new tuner if that's the case. Saving a few hundred now isn't a saving when you're up for a $6k engine rebuild.

This is so easy to solve.

1. Run car on dyno with new maps.  Hookup timing light to indicate what timing it has when it is knocking.

2. Repeat with old maps.

3. Consider difference between timing readings and wonder how hard it would be to reduce the timing of the new maps to something similar to the old maps.

4. Might also be worthwhile looking at the mixtures at the same times, just in case your tuner hasn't learned to dump in a bit of extra fuel at peak torque.

I'd be looking for a new tuner. Someone who can confidently tune your ecu and not have it knock.
