In looking at some scalers for the canister purge feature, i see both of the enable and disable MAP scalers are set to 0 kPA? Why would that be? Seems like the function would never work, if they were both set to 0. There are several other canister scalers, and they look like they are set to reasonable numbers. ARFP bin with $8D. I am getting back into the PROM thing, so time to start fine tuning. Most of my settings are still stock.

It all depends on how the code was written. They do a lot of weird stuff, many times to disable a function.

From what I've seen the main parameters for canister purge are minimum MPH, minimum coolant temperature and minimum TPS.

Yea, agree, have seen some weird stuff. I looked at cupala other bins, and they all have the same settings. I will likely just leave it alone!
Thanks
