As we know, the Hondata ECU reflash for MY06+ comes in two flavors:

1) Stock
2) w/ Toda Header

I have a J's spl header, which is tri-y design, equal length 50mm primaries, 55mm secondaries, 65mm collector. The toda is also a tri-y design, with 45mm primaries (not sure on the secondaries and collector).

Of course, you could technically use the reflash with any header, esp if it is a tri-y design. However, one must note the A/F ratio.

My question is, has any MY06+ owners with a J's header done the reflash, and if so, know if their A/F falls in a safe range?

 

I'd like to know too...

 

Try this from Boofster. Check the 16th post for dynos.

thanks!!

what a small world, i just bought something from boofster a week or two ago!

 

I guess the verdict is way too lean.

 

Checked with two tuners in town and they say 14.25 (highest point reached) is nothing to worry about on a non-FI engine.

They are very respected in town and have no incentive to give me wrong info. I would tune it out if I had a tunable ECU but maybe someday when the SC comes....

The car is driven hard daily and I've tracked it to the limit two weekends since the reflash. No issues whatsoever.

 

AEM EMS FTW

 

Hondata was absolutely great for my GSR, but the AP2 needs the AEM ems.

2004 that is....

 

We will soon compare an 04 AP2 full bolt ons , aem ems against a full bolt on 06-07 AP2 hondatafied.....Place any bets?

 

boofster's a/f was taken from the tip, that could easily be .5-1 higher than from the header section, so that would put his peak a/f around 13.8-13.3 which is perfect for a mild n/a setup.
