I have been researching on getting an accessport but im not sure if it is the right choice. I am completely stock and would just like to flash to stage 1 for now. So here's where the questions start, if i just install the stage 1 map from the accessport that is that has to be done correct?.. And same would go for stage 2 if you had all the correct mods?
I am new to all this.. I am in the air force so dont have much time to research during work or much time after work.. so any information would be great.. thanks.
Yeah. Basically a stage 1 is just a flash. It overwrites the (arguably bad) stock tune with the Cobb tune, and
you can flash back to stock if you want.
Stage 2 requires a downpipe at a minimum.
The cobb website outlines the exact requirements (fuel type, intake, etc) for each individual tune.
All you do is buy the accessport, download accessport manager on your computer, download the map you want, and then plug it into your ECU and follow the sequence to update (instructions come with the AP). It is very easy and takes less than 10 minutes.
Thats what i thought but with stage 2 i have read that you dont just use the map you actually have to either tune it yourself or get a protune done is this true? Or just a map would work just like for stage 1?
Works the same. After you install the downpipe you just flash the stage 2 map.
It is important to do data logs after to make sure the car took the map ok. If you do that post them up here and there are people that will look at them for you to help you out.
No difference in the accessport itself, but with the maps yes. If you buy from Perrin you get the Perrin map as well as the Cobb maps (for free).
With Perrin, it is a good idea to use these maps if you use their CAI, as COBB does not design maps for that intake. Also, if you keep buying stuff from Perrin, they usually do upgraded stages (to stage 2) for free. They are very helpful and have actually done 3 map revisions for my stage 2 tune over email.
No prob. Just make sure you follow the instructions on the various stages (map notes). Don't be slapping on random parts (like a atmospheric BOV) and think that it won't effect the way the car runs!
You would want a recirculating blow off valve (bpv). Not atmospheric. The air is already charged when it gets to the BOV, so yes, it could cause the car to run rich. Not dangerous like running lean, but not ideal either.
