exactly.....
now you are getting what i really want to discus about...

i think we are on the same parallel line.....

by the way where is your shop?
i wanted to open a workshop...

may be i can join you...
or help each other...

the load, fuel, the air, its temperature, also the exhaust gas readings etc are required for ECU to understand the current situation of engine. i know that. thats what i called parameters...

engine load rpm every thing comes under that...

what we do in our country is...
we do all the mechanical side in our workshop...
like turbo, inter cooler fuel injector, fuel pump everything except the ECU thing....

as i told you we are not good in that side.
and we send the car to pete's. they used to remap the ECU for us..

i think now you got me.
i think now you understand what i am looking for...

as u know, now a days only mechanical alteration is not enough...
