It depends on the table, most (the vast majority) do not share an axis, so its not an issue, but something to be aware of if you run into unexpected conditions after changing axis points. The load targets have their own unshared axis, so no worries at all with those tables.

These values can be modified in ATR/ATP, but you have to be careful as some axis are shared with tables (some of those tables may not be defined) and you could cause issues with something you're not trying to modify.

Like I said, shoot me an email if you have other concerns/questions/feedback.

OK, I'll forward you a couple of emails. I don't have ATR in front of me to look at what I was talking about, but here's an example of what looked weird to me:

Limits Tables: Load Limit (Tuner Code Bank 1) ...and Bank 2...
X axis labels all 7.00? Y-axis labels also seem wrong.

Henry said it was odd but correct and came from the DME. That may be true, but it still makes no sense. I was hoping to get more of an explanation than that.

I replied, but I'll get you as much info on those tables as I can. I'm in the middle of debugging, so you caught me while I was compiling code and had a quick chance to respond.

Did a 1/4mile test using cobb

i dont know how accurate is the 1/4 mile test on the cobb. But i just wanted you guys to see and tell me your opninion.

i am sorry if this is the wrong place to post.


i am located in saudi arabia

it wasnt my best lunch. i was on DS and i didnt remove traction control but the brand new good year asymmetric 2 are very grippy. 265/30/19 back and 235/35/19 front.

i am on stage2+ sport with 95 RON or 93 octane. Its a shame we dont have 98 ron or 93 octane in saudi arabia

vrsf DP, stett cai, vrsf IC.

i took a pic of my cobb screen with the results.

You'll need to pick up a WOTbox until Cobb releases it. Good news is its universal, so resale should be pretty good.

I know, but Im not in the mood to open up the ecu box again, I have a bunch of wires all mixed around with jumpers for my HFS-4 kit. I don't want to add more wires to the equation. lol

I have the same setup(Cobb, HSF4, WOTbox), it's honestly not that bad.

Just passing this along, but word on the street is that Cobb is going to be releasing hardware for the N54 very soon... starting with a stepped core FMIC.

Wouldn't be surprised, n55 tuning is done so looks like they've started on other things...basic suspension stuff was released too.

Just got my Cobb AP put in stage 1 ST sport , runs awesome . I want to move up to aggressive we have 93 oct gas here in Texas and besides the factory oil cooler car is stock. Would it be wise to bump up to aggressive , asking because read some posts discussing how some 93 oct fuel may not be the best for stage 1 aggressive.

Try it out and grab a log and see how it looks.

+1 just datalog stg1 sport and see how the car likes it, assuming it's in good mechanical shape you shouldn't have issues, that's a very mild tune. If the log is more or less clean, feel free to move up to aggressive, 93 pump from a good gas station should be perfectly fine for that. Outside of the ethanol mapping, all the Cobb maps are made for 93 pump gas, so don't worry about being low on octane.

Ok so might be a dumb question... My Cobb should be here tomorrow or Monday. I've just read the manual online and it mentioned updating the AP before installing. Honestly off the bat with no other mods, and first time delving into something as advanced as cobb can be, I'd probably like to stick with a simple map and since I only use 93 probably aggressive. So my question is dose anyone have any idea as to which would be the best for a simple user, without being a beta guinea pig?

It's clearly stated on the Cobb sight when you click Map Notes. Anyway, you can run the Drive or Sport Stage 1 Maps, and likely the Stage 1 aggressive map with 93 oct fuel. Try each and see what you like. Plus, each of those maps is offered in Linear Throttle and Standard Throttle. I prefer the ST, but it's really personal preference.

Thanks! Yeah I see I should stick to the non-race maps, but once you click in there it says I480s to ILA0S IS... How do I know which of those would be the correct one, or are all they all the same?

When you install the AP on the car it will tell you what ROM you have. However, you don't need to know that to update the firmware. Also, run stage 1 sport map. If it datalogs cleanly then try the aggressive map.
