Maf sensor to IAT sensor on a boostquestion

[tsxmiichael]

Hi guys how are you today! I have question! I have a automatic transmission tsx cu2 and im try to see if its possible to eliminate the maf sensor and remplace it with IAT sensor! Or i have to used a adapter and leave it connected the maf sensor and install the iat in the pipes

The MAF must remain connected and in the air stream even if tuning via speed density.

Where should I locate the maf sensor! In front of the turbo inlet or in the piping?

[Spunkster]

I would recommend similar to an OEM setup.

I locate the mad sensor here where i mark in the picture! I was thinking to locate the maf sensor in front of the turbo with a filter and pipe and the IAT close to the tbody! Will thag be correct or should i leave the maf sensor where i locate? My worries is that it will get psi

Something like this but i will have to get a 4” tube cause i have a 6262! And im not sure if the filter will make me loose some power there! And also put the IAT sensor close to the tbody And thanks for responding

Question i will leave my datalog to see if my AFR is bad cause from nowhere is starting to boost cut now and sometimes it try to turn off, and when i turn the primary oxygen sensor off it get into boost but it not tuning ok! There is not boost leak or anything! The car was fine and one day i just turn it on and every time i go into high boost is boost cutting but its not going to the boost its set

It looks lean. You may need to discuss this with your tuner.

Thanks! I using e85 and not sure if the e85 im using is bad! My sensor reading 77% i have it in a gasoline container for like 2 weeks i mix it a bit with gas and drive a bit better but I definitely will and also 🤔 i will have to check my injectors just to make sure! I out a old tune and it get into boost but it hold me back and i keep my eyes on the afr but i will see what my tuner say, i text him but he haven’t responded yet
