I have a tsx 04 with
Skunk2 cat back exhuast
Ct headers
Fastline hu flow cat
Injen cia
I send my ecu to hondata to get reflash with a paper stating my mods in my car and now i got skunk2 intake manifold hondata intake gasket zdx throttle body and unorthodox pulleys ready to install but i was wondering if i would need to send my ecu again to get it reflash or can i just install my parts?
I keep hearing that i have to send it again but its not solid answer yet just want to make sure first

Unless you negotiated some special service with Hondata, the reflash settings are not tweaked for your individual mods. It's one program for the model, year, and transmission type. The ECU will adjust itself for variances in air, fuel, etc.

If you want further tweakability, you need to look into the K-Pro or FlashPro, but they're probably not worth it unless you're supercharging or turbocharging.

What green_henry says is correct. The Hondata Reflash product is a "one size fits all" particular to each make/model/year/transmission combo. They adjust parameters for a car based on upgraded I/H/E (intake/header/exhaust). If you switch from one CAI to another, for example, the reflash will NOT be changed if you had it "re-reflashed". It's ONE reflash, regardless of mods to your car.


What being said, any additional mods can provide gains on their own over others, but that's not attributed to the ECU reflash.


If you were to get new VTC gears on your cams, for example, with a wider variability, then Reflash will NOT help and you will need to go with K-Pro or Flashpro, as you can customize the ECU further with that.

Thanks for the info this helps alot with my build just one more question
This are the last performance upgrades am doing maybe some other fuel injectors but no turbo or supercharger for sure what yall recommend just keeping my ecu reflash or going for a honadat kpro or ktune?

green_henry

I've tracked my car, and it was never starving for more fuel. New, bigger fuel injectors are only going to be worthwhile if you supercharge or turbocharge. I'd stick with the standard reflash.

You only mentioned your engine mods. The money you'd spend on injectors would be better spent on tires, brakes, wheels, and/or coilovers in my opinion (and in that order).

Thanks thats what i thought too not going for fuel injectors ill just buy some bbk spoon or acura ?
ive already got tein super street coilovers
New works wheels with tires
Drilled and slotted rotors
Stri the inside put in sparco seats with takata and going with wire tuck and take out the ac

you're fine w/ reflash

if you're going heavy mods....flashpro or kpro

tsx boy as curls mentioned try out the vtc gear as well as the 06 cams, you will notice a huge improvement along with a reflash made for 45 degrees.

Your doing all this little stuff like gaskets, and spacers, but forgetting the mods with much higher gains.
