Question : rsm install

[drayrunner]

I'm about to install a rsm supercharger i just bought , being new to boost i have a few questions, it came with a maf senser, how do i find what its off of or what type it is. also i have a dhp tuner - scanner what do i need to do so i can see boost on the scanner, also is there a wideband that i can use as a replacement for my narrowband. thanks

You won't see boost on the scanner as your car will have a 1-bar map sensor. 2-bar sensors are good to 14.5 psi but no one has successfully programmed a pcm that normally used a 1-bar sensor to properly read a 2-bar one last I heard. You'll probably have to rely on an auxilliary gauge.

The Innovate LC-1 is a popular wideband sensor with two programmable outputs. One of which can be set to simulate a narrowband sensor for your pcm to read.

As for the MAF, when in doubt, stick to the one your car came with. Unlike the map sensor, it will be able read the extra airflow.

No true. My '97 ecm relies on only the MAP and I have a 2 bar installed.

The stock MAF may or may not work properly. My pegs my AFR at 10.0:1 on only 6psi because its maxing out my MAF capabilities which is why I usually only run on the MAP.

Installing the 2 bar without making adjustment will most likely set a code as well. I think mine did when I first did, or it wouldnt run on it. I cant remember

I suggest that you hook up a GM 2-bar MAP sensor to the boost side of the SC and feed the output into your PT using one of the analog inputs.Use the following transform to convert the out put of the 2-bar MAP to psi: ((N0/51)*5.8566)+0.3456
I also suggest that you install an LC-1 WBO2 in addition to the standard sensor. and use another PT analog input to scan and log it (you'll want to use the 1.2.2 release, the newer ones have a bug with reading the A/D inputs). Use this transform to convert the output of the LC-1 to an AFR: (N0/51)*2.98+7.5
Good luck with your mods.

you never messaged me so i knew you got everything ok,i labeled everything for ya,the reason i didn't take the sc off the shaft is its a pain in the ars to bolt back up so i figured i'd make it easy for you the biggest pain in the ass is gonna be tapping the oil pan and getting that weird concoction in where the oil sending unit is
FYI..."you can get the tool to take the oil sending unit from the parts store"



i did take the time to polish the polished parts up alil more so it looked good when you unpacked it and creamed yo pants

After installing and running it for 10 minutes, i turned it off because it sounded like it was going to destroy itself.

you got the oil lines ran properly?

you do know you have to add extra oil to the motor because of the sc correct.. i believe it was half a quart,fyi

throw up a pic of it on the car.

or pm me with a pic
