Stock basemap (for hondata) or instructions request

Post by turboroe »

Hi guys, can anyone send me (or help with the steps to create) a stock-style basemap for my civic so I can use hondata with regular gas?
Or even how to adapt the basemaps for use with regular gas?

Why do I need this?

* During the week days I like to use Premium for extra power.
* I travel a lot for surfing, and when I travel I would prefer to use regular gas for economy (premium is 40% more expensive here and nearest beach is 500km far)
* When using regular gas on basemaps, I get HUGE knock counts (like 200 per hour compared to 0 count with premium fuel) and my S.TRIM gets crazy high (around 30%) which makes gas mileage suffer a lot on the highway (my afm calibration on premium gas is trimmed to almost flat 0% on the long run).
* If I reflash back to stock, my stock AFM calibration is poor and I get that hideous "gear simulation" when I floor it. Plus I can´t use hondata traction control which is great.

A stock like calibration is not going to help.

Where are you, what sort of gas and what modifications?

I think that you need to address the AFM reading first until the short term trim is close to 0%.

Once you have done that I believe that you should be able to switch between fuels and let the knock control adjust. Unless one fuel has ethanol and the other does not.

Some datalogs would help.

* I am in south of Brazil (weather is not very hot here)
* Car is stock, no modifications. Mileage 5800km, never had any problem and runs strong.
* Premium gas has no ethanol.
* Regular gas is E27 here.
* AFM was calibrated on premium fuel to close to 0% while urban driving.

Here are some datalogs:
* Urban commute on Premium +6: from my commute to work, just to show how my STRIM is normaly, after AFM calibration.

* Highway trip part 1 - premium +6: Same fuel and flash from above, but I noticed now that the STRIM is very high, it is mostly lean. It NEVER did this on my commute. I was using on cruise control most of the trip (probable cause?). I ran on this fuel until the tank was empty.

* Highway trip part 2 - Regular +3: Then I filled up with regular gas and reflashed +3 basemap at the gas station, and recorded the second datalog.
STRIM is still acting strange.


So the fact that one fuel has ethanol and the other one doesn´t, how does this affect things and how to remedy it?
I would like to have 2 calibrations if possible, 1 for premium and another for regular without my kcontrol and kcount going crazy.

You will need a flex fuel sensor if you are switching between E27 and regular fuel.

In Brazil, by law, all fuel must have 27% ethanol added (renewable energy incentives), so our regular fuel actually is E27.
So the brazilian Civic is built to run on E27 stock here, then the ECU must be capable of dealing with the 27% alcohol somehow. Maybe it already has some builtin sensor... When I reflashed back to stock and datalogged, my knock control was smooth and low running E27.

The only fuel here without ethanol is Premium, but it is so hard to find and so expensive that almost nobody uses it (i think less than 1% of gas stations have it). Fortunately there is one close to my house, but then when I travel I am forced to use E27 for the reason mentioned.

I guess the best solution will be to reflash to stock when I go on a long trip.
Any chance you could make some kind of quick map swap, between stock and +6 psi ?
Thanks.
