Puffwagon Posted February 14, 2021 Share Posted February 14, 2021 Howdy folks, I've noticed that my map values in the log have changed recently and don't read the correct amount of pressure. I used to subtract the baro pressure from the absolute map in the log and that would give me my boost reading. The highest I saw was 46 absolute or something so I figured that it was getting data from the 4 bar boost sensor. Lately it looks like it is pegged at 23psi which makes me wonder if it has reverted to the stock Tmap. I was doing some tuning yesterday and ran about 40psi of boost according to the dyno and the log still shows 23psi. I also noticed that the boost error is always showing it to be under which has been causing the closed loop boost control to go nuts. I asked for 27psi after 5000rpm and it ran 40psi. This was ok as I knew it was going to happen and the fuel was there etc etc, but it seems as though there is something going on. Anyhow that's about it. Any ideas are appreciated.
