143838_WOT = describe behavior, etc.
144020_low_RPM = describe behavior, etc.
144051_shifting_2nd_to_3rd = describe behavior, etc.

One thing to keep in mind during this is that the ECU will cut fuel if RPM is above the Fuel Restore RPM once Ignition Timing is allowed to retard to the full amount specified by the Decel tables. So, for what manometer wants, you want to reduce Timing quickly to almost the full value but not let it go to the full amount.

Rossi, please don't try to use values from files I'm modding for manometer. He is going for a completely different type of decel noise than you. The approach for him will probably not work for you. The approach for you is way different since we want decel pops to happen all the time off-throttle and not just for a few seconds after throttle lift.

Also, I just noticed that both of you have a lot of decel tables modified from stock and the mods I made may not play well since you've gone so extreme on some of the values. So can you both please post your files with all the decel tables returned to stock for your vehicles and we will make small incremental changes and go from there.

Give the attached file a try. I converted all Deceleration tables to stock MS41.2 and then edited a few. This file is intended to have decel pops all the time.

Please post logs from this so we can revise as needed.

There has been lot of discussion about how to get rid of the rev hang which is present at least in ms41.0. I tried lot of things like using the ms41.2 deceleration maps but I wasn't happy with the result. It was better but still the revs didn't drop as fast I would want. I also played with the Fast decreasing TPS -detection maps, but with those I couldn't get the result I wanted, and in most cases it just made the car undriveable. Like there would have been kangaroo gas in tank

But eventually I found easy way to get totally rid of the rev hang without negative effects:
- First raise the ignition Retard - Decreasing TPS - step size so that the minimum values are 10.
- Lower the Ignition retard decreasing TPS (closed) maps by 10.
- Lower the Ignition retard decreasing TPS maps by 15.

Then flash the new SW and go for test drive. There shouldn't be any rev hang at all. Here is ms41 file you could use to copy the maps: https://drive.google.com/open?id=0B2EFG ... 1JrTjFhQUk

Then in addition to that if you want lot of exhaust popping when deceleration:
- Put the Fuel restore - RPM maps above your RPM limiter. So that it wont cut fuel when you are decelerating. (you need fuel for those pops).
- Lower the Ignition retard decreasing TPS -maps by another 10 degrees compared to the previous setup.

This will get your deceleration sound like this (I have almost stock exhaust so it's not very loud):

(I will add file later)

Then if you want it more aggressive you could increase the step size and lower the Ignition retard decreasing TPS -maps even more. While decelerating you would want about negative 20 degrees of advance for loud pops so use logging to found how much you will need to lower the Ignition retard decreasing TPS -maps. but 20 to 25 lower than stock will give the same effect as in that video. I didn't want to test more because THIS WILL DESTROY YOUR CAT. And if you don't have CAT and want flames you could add some unnecessary fuel to base fuel map to the lowest load column above 1600 RPM.
