From other threads, I know that Hondata works especially well with bolt on mods such as Comptech Icebox and Comptech Header. Even without those mods, Hondata gives plenty good gains. My question is does it matter whether I get Hondata first and then the other mods? Or is it always better to get the other mods first and then Hondata so the ECU doesn't have to re-adjust to the mods? I am planning to get Hondata first and then if craving more power, go for the CAI and header. But it's better to get Hondata after those mods, I can wait.

 

go the slow but sure way...dont go for the biggest bang first...take it gradually one at a time you'll enjoy the modding process more knowing you have another mod to do and feeling each improvment as you mod that aspect (suspension, brakes, hp)...for the last 2 years ive taken the approach of 1 at a time first intake then springs then header and last exhaust...hondata is next on my list probley in spring

 

In your case the sequence of mods doesn't matter. The ECU will adjust to whatever you put on.

 

It depends on who you talk to. There's a mod on the "other" board who completely trashes the Hondata reflash and is a complete proponent of freeing up the available power being bottlenecked by the restrictive OEM parts. He has good points however realistically, I heavily factor in bang for the buck since i don't have $800 lying around to get a shiny exhaust.

 

I disagree with that. It's a standard reflash, so it will adapt to other mods down the road. It's not like the reflash was designed particularly for certain mods. If there are different reflashes for different types of mods, then I understand that it would be better to do other mods before the flash. But there is only "one flash fits all" for now. I'm happy with my reflash even with no other engine mods. BTW, the "04 MT TSX with no mods" dyno on Hondata's site is my car.

 

Yeah, but soon there will be reflash for Hytech full exhaust setup.

Probably looking at $1500 and $1200 for current reflashed owners....

 

Hondata 1st, everything else 2nd

I don’t think there are any other mods besides a supercharger that will give you a long wide flat torque curve without the huge drop of +20 lbs of torque before iVTEC. This change in the torque will make the car accelerate harder in the mid/high-range rpms (3,000-6,000 rmps).

I like any mod that give me more torque in mid-range level because that is where I spend most of my time driving.

I have to wait until spring for my Hondata conversion.

 

Yeah I would get Hondata first. Having the Vtec lowered and be able to stay on the high cam after a shift makes a pretty big difference.

 

So for $1200 I would get a Hytech header, exhaust, and reflash?

That's a deal and a half considering:
Header $300-$500
Exhaust $800
Reflash $600

 

I don't think so. Knowing that the full exhaust is from Hytech, $1200 can easily be just the exhaust. The header can easily be another $1000. Hytech stuffs are pretty good, but aren't cheap.

 

Yeah, that's what I was thinking too. So is he saying the reflash alone is $1200 for an existing reflash owner? Where ya at Black_6spd? Just wondering what the pricing on the Hytech stuff actually is.

 

Exactly my sentiments.

 

I would do your bolt ons first just incase Hondata comes out with a newer version of Reflash

 

Thanks guys. Someone mentioned in another thread that the ECU will not be as efficient if I add the other mods later down the road because it has already adapted to the engine without the mods. It will adjust but maybe not as optimized? I wonder if there's a comparison dyno of doing Hondata in the two different order. I am definitely getting Hondata for sure but the two other mods don't seem to yield as much gain for the money so I am hesitant on that....but I don't want to screw myself later on if I do get them.

 

okay, from what I understand is that the reflash is the same for all tsx's and basically all they change is the mapping, vtec point and rev limit. they don't reflash your ecu according to the mods you have on your car. so it's going to be the same if you add the mods before or after the reflash.

basically the reflash is a hondata tuned version of our stock tsx and is not tuned according to our mods. as for the mods, the ecu will adjust itself to those mods after you reset your ecu or if you don't reset it, it'll adjust to it over time.

 

The ECU is always adjusting, whether it is to your driving style or to a new mod. The reflashed ECU will do the same. It makes no difference to the ECU what mod you do first or even if you do all your mods at the same time or seqence them one every weekend.

 

Sorry, Kenny. Just opened this thread. For some reason, I thought it died.

I was only guessing at what it might run. That's why I said "probably." Guess I was wayyyyy off.

Wait a minute -- what does it matter to you anyway?? You're already hooked up...

 

Just wondering how much Hondata is charging for the Hytech reflash since it's a custom one.

The dyno for the Hytech setup looked great though.
Full Hytech exhaust system =
