When I got my car everything was normal but after some time the car started to backfireing. I didn't changed nothing...I ordered datalogit but havent received yet, so I don't know what settings there is. Car is JDM model RZII and tuned by R-Magic. Maybe the PFC is "PRO" version and anti-lag is tuned ON?

You likely have other problems - the anti-lag is really tricky to get working. I'd start checking typical problems that could cause that - worn plugs, bad sensors, etc.

I imported a car a few years back that had pfc pro and was tuned by rmagic, it had antilag enabled and killed two turbos is a very short space of time, it would shoot flames at idle. Check to see what ecu you have, if it is an apexi you need a datalogit, as rmagic use map protection and if any of the settings are changed the car runs like a pig, similar to yours and turbo glows red.

 

thanks for the useful information.

Yes, there is Apexi PFC with R-magic sticker. I don't know is it "pro" or not...
Datalogit is ordered and houpfully get it soon.
