Honda Civic Si AccessTUNER Tuning Guides, Worksheets, and Tuning FAQs.

[COBB Calibration Team]

We have started this thread to allow us to publish some initial information about the AccessTUNER Tuning Guide and to hold open discussions about how to properly tune these vehicles using the AccessTUNER software. The Tuning Guide will likely be revised on a constant basis based on user feedback, questions, and concerns. We want to make sure the tuning material is effective for AccessTUNER users so please feel free to give us your feedback or voice your concerns. We've attached a Sample MAF Batch Analysis spreadsheet that you can look at for reference. This spreadsheet is meant to go along with the tuning guide in order to make data analysis more effective.

Please be aware that new AccessTUNER Race users have access to this section of our forums as well. Please welcome them accordingly.

Below are some FAQs that may be helpful when it comes to understanding what tuning changes may need to be made to customize a map for your particular hardware combination.

My car has been performing consistently, but now that I've removed the coolant lines from my throttle body, my LTFT values have gone from close to zero up to +8 to +12%. Would removing or by-passing the coolant lines from the throttle body cause my fuel trims to change it that much?
Removing the coolant lines to the throttle body is proving to be a "significant" modification as far as the ECU is concerned. Removing these coolant lines will likely allow for poorer fuel economy as another side effect. As will setting your fans to turn on at colder coolant temperatures. Combustion chambers are more effective at warmer temperatures and having coolant warm up your throttle body helps increase the intake air temperatures to a more efficient temperature for internal combustion. We are just stating this so you have an understanding that much of what Honda did was done correctly for a performance street vehicle. We are simply trying to do our best to explain what could be going on with your vehicle after a recent mechanical change.

How many MAF revisions are necessary to get my fuel trims closer to zero?
We have seen that it takes anything from 1 to 4 MAF revisions to get your LTFT values closer to zero. If you notice that your LTFT values suddenly change, then it is likely that something has mechanically changed or you have used a fuel that has significantly different qualities which requires the ECU to make fueling corrections in order to hit the closed-loop fueling targets.

How do I set my my Launch Control (LC) RPM using the AccessTUNER Software?
Step 1, figure out what RPM you most effectively launch at.
Step 2, in the ATR software, change the left hand cell values in the
Rev Limiter - Disengage Fuel Master &
Rev Limiter - Reengage Fuel Master
to your determined LC RPM.
Step 3, save the map, transfer the map to your AccessPORT, reflash the vehicle and enjoy.

The further apart you set these LC RPM values, the slower the stutter-step will be.

We wanted to start this thread to help out ATR users with communicating how they have made various changes to different ECU tables.

Step 1 - Go to the ATR software and highlight the entire table content you are looking to post, press CTRL+C to copy all highlighted table data.
Step 2 - Start a thread on your favorite forum. In the body of that post press CTRL+V to past all copied ATR table data. Enter the following text before [code] and after [/code] the table data...remember BRACKETS AND SLASHES MUST BE USED APPROPRIATELY. Please be sure to preview your post so you can verify the table data is displayed appropriately. This format may not work on all forums, but I know it works here.
Step 3 - Rinse and repeat so all of your ATR buddies can easily post various ECU calibration data up for others to test, critique, and enjoy. .

You are welcome to quote this post so you can get a better idea about how the text and data needs to be formatted. The process is super easy to be honest, give it a try.

The same simple copy and paste functions can be used from this thread to the ATR software as well. Just use your mouse cursor to highlight the appropriate areas, copy the data and paste into ATR for testing. Please remember, as the Beta ATR software evolves, some table data may change due to changes in data conversions, formats, being Standard or Metric units, etc.

We hope this helps,

I'm definitely putting those in later. Should improve throttle response, among other things. It would be nice if Cobb shared their opinion on how this affects the car...

[COBB Calibration Team]

hmmm, so can i put those JDM throttle tables in and be ok? What exactly do those tables do?

You are welcome to read through the Tuning Guide in the ATR software to get an idea as to what this table does. These table settings appear to be a little more aggressive than stock.

he's teasing us with the CTR throttle tables.

^^ is this v102?

That really depends on what some of the Beta testers are reporting back.

COBB Calibration Team.

[mjrn.]

report back after you test out the throttle body table! I'd do it but I just got back from a long drive testing out your suggestions!

[mucter]

The FD2 throttle table numbs our midrange response. Here's the hybrid map I posted on 8thcivic.com. It takes all of the numbers from the FD2 map that are greater than the stock numbers and combines them with the stock table.

I noticed ALOT of the values in our throttle tables were almost twice as high as they were in the type r tables what exactly is the relationship of the table values? Why is a lower value more aggressive than a higher value?

[mitsukaisi]

How awesome would it be ifthry got whole of the mugen rr throttle tables

[mjrn.]

I believe it's because the ctr has a shorter FD and more power, so at lower-midrange revs it doesn't need as much throttle response as us. There's been a hybrid made of our OEM and the CTR throttle tables, basically discarding the lower values and keeping the higher ones.

You can find it on the the 8th Cobb beta thread.

[mitsukaisi]

It's posted above here too I just flashed it to mu si
