I sure then just change the number on the map and load it up right

Where does the MAF voltage sit at its slowest point of idle? Or what is the lowest voltage in your log? I would set the minimum just below that.

You would then just copy the new scale into your, obviously checking it looks right.

SO have a question similar to the OPs. GOing to ask here instead of making a new thread.

I am having trouble loading tunes files to my OFT. CAl number ends in B01C. All the tunes on the table end with B01C. Trying to ditch stage 2 EL for stg 1 93 and it will not load. Says checksum invalid? Little help would be appreciated. I am reading like 7 threads and still cant figure it out

No editing of tune done ?

if no editing done and its just a supplied oft tune then not all oft tunes are checksum corrected just get ofm/oft to correct checksum and you will be ok.

I have an oft on its way and I'm a noob too. I won't have a problem using the stage 1 91 octane tune with a drop in filter and cat back right? They advertise it saying even noobs can use it but I wouldn't know how to log and what took look for, check for knock, or all that stuff.

On usa fuels you will be fine its only us aussies on our rubbish fuels that need to tweak tunes , also drop in filter and catback will be fine on stage 1 tune

One more question for you about knock. What is considered a bad knock? all knock?

While on the highway with cruise control on, I would get an occasional knock of .32 or .64

Every once in awhile there would be one up to -1.04, and once on my six hour trip it when over -2. All of this was while just cruising highway at a consistent speed.

Then got to the back mountain road and romped on it, and got no knock what so ever. And I mean romped on it. 1/4 of fuel on a ~35 mile stretch of road

yes rhat is pretty common lower rpm 1500-3500 high load knock especially in high gear.

you can pull a bit of timing in that area rpm/load points, or try different brands of fuel some better than others. did it cause iam drop. if you puul 0.7 degrees in that area should remove most of that knock with no noticable effects.

look like its all good higher rpm so thats good.
