How do I get read off the pops on deacceleration ?

Rocket 3r 2022 with Panner map . I have the Dominator exhaust . I have removed the SAI with plates. Add 20% to the 0% throttle position on F tables . Did not helps Lots of poping

A professional tuner could do a tune and fix that fueling problem, unexploded fuel entering those pipes.

It is a little bit of a problem to find a good tuner here and it can cost me 800$ at least . I am trying to save it

On my old Rocket I added 15% more fuel to the last 6% of throttle and that quelled most of the popping. Not saying that'll fix ya, just what I did. Haven't dorked with the new Rocket's tuning beyond doing the 100% throttle opening in SPORT mode. And I have the stock exhaust still on. After I get it broke in I'll proabably upgrade fueling to the cutom full power map in TuneECU (but keep my current map just in case).

It has to do with fueling and smoothing out your AFRs in closed and open loop. You likely would either have to get some wideband O2 sensors and do it yourself (I don’t know if the rocket even has a tuner that allows you to log runs and adjust tables) or get someone who can dyno tune it.

what do you mean "Last 6% of throttle " ? at what table?

I'm going back in memory here and had to pull out my old TuneBoy notes. The L tables were used to add the fuel on all three cylinders There was a diagram of the affected cells on the old R3 Forum (now defunct) to add 10% and 15% fuel to quell the pop. There's also a note by the author that says the pop may come back as adaptation occurs and reloading the map fixes it (or you could try resetting the adaptation I suppose).

I did smoth it . I don't think that the o2 is the problem , any way I am going to eliminate it at all

The L table on the 2.5 Rocket is air pressure ( hPa )

Difference between Tuneboy and TuneECU, I suppose. Tuneboy was sold out of Australia if memory serves, so it's probably not the same L tables as TuneECU's. You might try getting on the TuneECU forum and posting a query.
