I think when you plug in your cobb AP it tells u?

Thanks, I guess I'll find out next week if it arrives by then.

I feel the same when i flashed from v203 to v301. Old maps seemed to be faster the the new one's!!!!!!

[bmwm3redblack]

But i don't care cause v301 is very stableno codes,no jerky shaking.
And i'll go to stage 2+ spring time anyway!!!

I am MT and also believe the v203 91 octane stock throttle is more fun (powerful?) to drive compared to v301 91 Octane (Sport) stock throttle.

Konnectid, which ECU do you need the maps for?

anyone else actually prefer the 203 maps? is there a reason why 203 aggressive actually feels more aggressive than the the 301 aggressive maps?

I have and I felt the same way you did and I'm actualy running V203 again

I installed catless DPs and flashed over to V301 stage 2. After a couple days i flashed back to V203 stage 1 and it is sooo much better to drive. stage 2 linear throttle is kind of a let down. Stage 2+ stock throttle is a freaking beast.

Hello everyone! After returning my car back to 100% stock for a dealer visit (I got some injectors replaced) I just installed my new Cobb AP today and I want to see what it's like before I re-install all the other mods again.

Can someone please send me this V2.03 stock throttle map everyone is talking about? I have I8AOS and my email is eracer76@ymail.com ... I would love to try it out, Thanks!

I ran a 12.6 in the quarter with 2.03 and no other mods except Cobb Accessport and I am almost 100percent sure I would not run those numbers on map 3.01. Its just an assumption but when I go to the track I will run them all.

12.6 on just the cobb? that sounds really damn good. are others seeing anything close to this?
what was ur 60 and mph?
are u talking at the strip or in your ap?

[matty088]

cobb should explain what they change when they do map updates....dont u think?

Sorry to come in kind of late. I just recently purchased the Cobb AP and am running stage 1 aggressive-stock throttle v301.

My ECU ID is 18A0S as well, could you please email me the v203 maps? I am running 93 octane.

Just curious if people still feel that the v203 is more powerful than the 301...seems like the 301 has been out for sometime now and maybe some changes have been made?

I didn't feel it to be more powerful, just had a different feel; it was as if the boost came on earlier. For me, 2.03 was unusable as it was constantly throwing codes and felt very "jerky". Granted, many users had no issues with it yet had a lot of issues with 3.00 which worked fine for me. I've been using 3.01 and that seems to work much better with my car so my suggestion would be try them all and see which one works best with your vehicle.

I had them both dyno'd and they were almost identical. The guy that owns the dyno said that the V203 was too lean and the V301 was spot on. This is probably why Cobb revised the map.

[08-335]

^ That's what i was waiting to hear! love v301.

[08-335]

I just got a chance to load and test out the aggressive v203 maps. I have only driven the v301 maps and never the v203's. From the second i pulled away from the garage I could instantly tell that there was a significant increase in throttle response. I never got a chance to floor it but I can confidently say that at 10-50% throttle, I feel a much stronger pull than I did in the aggressive v301 maps.

Just run the Stage 1 tune with the throttle map of your choice. You can run the aggressive map since it requires 93 or higher octane. DO NOT TRY TO RUN STAGE 2 WITHOUT STAGE 2 MODS.
