what does our map sensor max out at?
Just did a blast with no filters and triggered a map performance range code.going to double check everything but could this be tune related?
Car is a absolute monster in the colder weather and just when I thought everything was clutch this comes up.

Hmmm....the map sensors I've seen go in .5 bar ( 7.25 psi ) increments.
Meaning they are 0psig, 7.25psig, 14.5psi, 21.75psig and 29psig.
The issue I see here is that I'm sure a lot of people go above 14.5psi in these cars ( I'm almost there myself ) but the next one up is 21.75psi which is high....hmmmmmmmmmm....

Never have seen that code before! Did you go real lean when that happened? Did it hit about 4500? Pretty sure my MAP is maxed and that is what caused the lean condition at 4500 and up and maybe even higher timing.

I wasnt watching the a/f as I was getting on the freeway and got on it hard in second and had to let off sharp while a car was merging infront of me.
The throttle felt weird after and was really sensitive at very little throttle input would almost jerk the car.
Its been really cold with high pressure up here lately and that might have to do with it.
I went to the gym and parked the car for about 45 min and then drove around a little and the pending code went away without clearing the ecu.
I saw over 30 psi on the intake manifold pressure while I was looking at the gage on my cell.
Could be a bad sensor or just a fluke?I did the tb not to long ago so the blower had to come off,Im thinking there might be a leak maybe also.

the p0106 code has been a menace to us for a while. i think it's larger tb related (directly or indirectly) as that's when i started getting that code on a regular basis. i'd love to get this figured out...

i started seeing that code with my 78mm tb several years ago and r/r'd the tb twice, replacing the map sensor both times. i continued to get the code with my 82mm tb when that came out and replaced the map sensor for the hell of it again. this is one of those areas that i just don't have an explanation for...but it's definitely not leak related.

If you're going to do the no filter run make sure that you reset your ecu before you start your car. The idea is that you want your car reading the air that is currently going pass your sensor. So take out your filters then reset your ecu then start off slow then do a few runs from a dig and few runs from 45-80 and see how she feels.

It bolts up perfect and I get 2.0-2.4 tps % in drive and no codes at all are coming up from the tb.
I have a spare oem 80mm that I bought just incase the amg 80mm caused codes but it didnt.
250 and its yours!!!

no adapter plate,I took an sl55 tb and drilled a hole into it at the same spot where the stock tb hooks up and connected that to the oil hose.
It bolts up perfect and I get 2.0-2.4 tps % in drive and no codes at all are coming up from the tb.

what are you mods so far?did you end up installing a bigger tb yet? let us know if you get this same code.
from the looks of it tbal got this same code when he took his tb off to do the tb grind.I think I lossened up the map sensor harness the other day taking the tb off to put a better sealer on it and maybe the harness is a little loose that is casuing the code.
I only got the code once but Im sure it will come up again.Ill take the intake off on sat and double check the map harness.

Any thoughts on that code having something to do with the intake air temp sensor?

This is only in part true, I have ploted the stock map Vs Voltage, It stops reading at 4.95 and is into the 20's however the computer will not read it up there. You will start to see issues around 3.8 volts or 17-18 psi

Hmmm...wonder why would Bosch do this? Maybe their timing/fuel maps only go to 17ish psi?
