Im new to the whole logging thing but ive been throwing some saved runs around on EVOSCAN and im just not understanding why its showing BOOST under MANIFOLD DIFFERENTIAL PRESSURE and/or psi. Because the readings im getting for Boost MDP are around 47-48 and i know its not psi unless its directly relative to MDP. Might be a noob ques. but i dont care. I havent found any material read on EXACTLY how to use EVOSCAN but have just been going through it to learn.

 

post this type of stuff in the ecuflash section.

 

Moved to EcuFlash.

 

MDP is the same RequestID used for the MAP sensor if your car was equipped with one. NO USDM EVO's were ever equipped with a map sensor capable of reading boost above a few psi, therefore its not very useful to log boost unless you are swapping a 3 bar MAP sensor in place of the stock 1bar MAP or MDP sensor (depending on what year your car was)

How to install it, and what other changes are required are a different conversation.

 

Thanks for that very detailed info....i guess il just have to monitor my boost gauge while loggging. I knew that reading seemed eroneous. Thanks again "JACK"
