zr1 map sensor

[BoostedYards86]

is this worth it to add to a car if your only planning on running below 10psi...how about over 10psi? Also how does one set it up in hptuners?

[DSteck]

You should use one regardless of how much boost you are running. Search the forum for 12592525 and you'll find the info you need.

Will a ZR1 MAP work in a 2011 Camaro ss? If so how do I go about tuning my car for that sensor with HPtuner?

[DSteck]

The LS9 sensor is a direct drop in. Plug the sensor in, then just change the linear an offset values under Engine Diagnostics -> Airflow.

thanks for the reply. can you tell me how i need to go about the new tune, how do i figure out what i need to put in, what do i need to caculate,or where to start? thanks for the help!!

[casper sc/ss/rs]

the numbers thats in my tune now are

map sensor linear 128.13 kpa
map sensor offset -0.31 kpa


so how do i caculate them numbers to get the numbers i need so my car will run again? thanks again!

Search the forum for 12592525. There's a thread with the values.

is this what im looking for?

linear 312.50
offset -11.25

if so thanks very much if not ill keep looking
thanks for your help!

[DSteck]

Yes.

thanks my car is running again
now its ready for the tune

thanks again!!

and just curious how do you come up with them numbers?

[DSteck]

They're taken straight from a ZR1 tune file.

oh ok

you seem to know the answer to all the questions i have so im going to ask 1 more thing,
how do i set the pid up to log the boost with the zr1 map sensor on my scanner what i had in there was totally wrong now? do i get 1 more help line

[carlrx7]

open scanner up, press F1, search Boost..

[casper sc/ss/rs]

open scanner up, press F1, search Boost..

thats what i did and its totally messed up now i put in what the help said to put in and when i scan its saying like 80to90 psi boost so thats not helping? i was closer with what i had in to start with and when i changed it i didnt write down what i had in there before so im back 2 square 1

[carlrx7]

this is what i use.

make sure to add the baro pid to the table

([SENS.30]-[PID.51])/6.9

thanks ill try that.

baro is your map sensor reading at acc on, engine off.. Unless there actually is a baro sensor.. I'd rather calculate boost by MAP minus average (seasonal) atmospheric pressure.. Then again, I have an E40 and lose logging speed for each additional pid.. gotta save those bytes..
