need help for tuning

[lp216]

Hi guys, i plug my F/IC and i'm looking for some kind of base to start tuning. So i look at the map for the SS, but i dont understand how it is working.

The aem unit is working this way :
0 = the unit shoot the same amout of gas
10 = the unit shoot 10% more gas
-10 = the unit shoot 10% less gas.

For the SS, all i see is 10 when not in boost, then 9.9 - 9.8 -9.7 ...
Is this mean 100% of the gas when not in boost, then 99% (so -1 in my unit), 98 (-2 in my unit), etc?

Can somebody help me with this

thanks a lot

I don't think it's a percentage change of the fuel exactly, but a change in the voltage. On splitseconds website (www.splitsec.com) there is a tuning guide...reading it is good background info even though it does refer to tuning toyota's w/ a different calibrator.

I don't have the data in front of me, but the 0.1 change alters the voltage that is sent by the MAF to the car's ECU. A value of 10 means no change, less than 10 would be removing fuel (I think for our application it will be telling the ECU there is less air coming in, thus the ECU will output less fuel), and more than 10 introduces more fuel. For a better understanding, go to the SS website, click on Products, then Air/Fuel calibrators, then scroll down & click on PSC1-001 Programmable Signal Calibrator w/Absolute MAP sensor. If you read through that, it will show you a basic representation of how it changes the voltage in a chart towards the bottom of the page. The "direct" column represents the input voltage from the MAF, and the "Signal Modify" column represents the voltage output from the AFC to the ECU, based on the "Cell value"

Allright, thanks for the info

did you find how to proper tune your protege with the f/ic ?
I'm working on a turbo setup for my 03 protege and i'm looking for a piggy back engine management and I want to get one that it is sure it will work well with my custom turbo setup.

please guys READ the F. manual... it says everything... I read everything and I tuned the car..

you tune the car by yourself? I won't take this chance...
