We put together this page in conjuction with Doug from Hondata, to help inform enthusiates about the new Hondata system.

Any questions you may have can be directed to the contacts on the page. Hope this helps.

 

Good info...just a quick question.

1. Can you use with a OBDII ecu? I have a 2000 ITR and am curious what I would need for full tuning. It looks like I would need a stage 4 and the reprogrammer accessory which is another 270 along with an OBDI ecu and adpater which puts the total around 1550 (thinking 200 for and OBDI ecu).

If that is the cas isn't the power FC cheaper for most of the same options except for the RPM options? Just curious, I am very interested in a Hondata, but I would like to get the best info on price before I commit

 

Ok, so lets say I'm on the dyno and I see that i should lean out my fuel from 3K-6K rpms (im pulling this out my ***) but your changes won't take effect until you re-burn the chip right? So then how long does it take to burn a chip, and are they reuseable?

 

No currently cannot use an OBD2 ecu, however an OBDI P28 ecu can be had for around $100.

Keep in mind that you may be need to get a full blown stage 4 setup, if you don't plan to tune your car every day or every week, you can just have someone with a stage 4 or a local dealer tune and burn a chip for you. Once tuned, there is no reason to modify the program after your off the dyno.. doing so would just be guess work.

We never have to modify our tunes once we're off the dyno.. the only time we make changes again is if we have any major upgrades to the engine. Its been 2 months now for us, and we've never had to change the program still.

Unless you're just looking for a cool gadget that lets you play with the settings whenever you please, then maybe you'd need that option... otherwise there's no reason to.

I've used the PowerFC and other stand alones, by far the Hondata (and the PMS) were the easiest the install.. it took literally minutes. The Hondata however is hands down the easiest to tune.. it is so intuitive and no to mention Windows based.

 

Depends.. if you have the burner and emulator, then changes to the tune are instantaneous. Just make the change in the Windows program and simply upload it to the ECU. Done.

If you don't have the emulator, then all you have to do is make the change on the Windows software, burn a new chip, and put the chip into the ECU. Start the car. Done.

Method one take seconds... Method 2, may take 30seconds to a minute.

 

Ok, so the emulator acts as the "chip" and any changes u make are instantly "burned" in? And, im sorry, i have to ask again, are the chips re-burnable?

I'm sorry, im stupid. Hence my avatar.

 

No problem.. You are correct, the emulator acts like the chip while your tuning, so you don't have to burn a new chip between dyno runs for example. Just make the change and upload it. The laptop is in essence, always connected to the ECU. Once your done tuning for the day, then burn the final program onto the chip and install the chip.. done!

Depending on the chip you use, it mayor may not be reusable..

I updated the FAQ portion of the webpage listed above which will answer some more of these questions

 

just out of curiosity why not just use a v-fac they work real good in the right hands

i have a boosted car that was tuned with a v-fac it will save some serious $

just a question im interested.

 

The two are in a different league.

 

much clearer! thanks a lot!

 

ok how much more power do you think you'll get from a hondata vs well tuned v-fac not only do you have to change your computer but you have to go through the dynoing. i would like to see a car with a vfac get tuned then change it out and tune with the hondata system i bet you would be suprised?

i have been given that chance at no cost to me i wil not say where or how but im going to decline it. i dont think it will be any better and beside i have to by a laptop if i want to watch my system that will cost me more money. im not trying to flame on the thread but so far i havent seen anyone's set up better on paper by a independent source... if someone can show me ill get one tomarrow..

 

If it were that easy, then how come all the top runners in NIRA don't just simply use a VAFC??

What the VAFC does:

-add/subtract fuel in 2% increments
-adjust fuel in 1000rpm increments at 8 data points
-change your VTEC

What the VAFC does not do:

-will not add any more fuel more than +8% - 10%
-does not switch the VTEC map when it switches the VTEC cams
-can't change your timing based on RPM or throttle position
-cannot do boost

What the Hondata and other stand alones do:

- complete tunability over fuel and timing
- adjustable in 1% and sometimes 0.5% increments
- unlimited adjustibility in fuel and timing in any direction
- non-vtec and vtec fuel and ignition maps are INDEPENDANT of each other
- will actually switch maps when VTEC switches
- can adjust timing based on RPM and throttle postion
- adjust in 100rpm increments
- works with boost or NA

What the Hondata and other Standalone do not do:

- look pretty


I'll take your bet. Any stand alone system will pounce all over the V-AFC simply because you can tune the fuel at 100rpm increments and tune the timing. The VAFC simply does not have this resolution or tunability.

 

So your saying you can butt dyno tune your VAFC to achieve better numbers than a stand alone?

 

When is the next software upgrade supposed to be released and are they gonna release new manuals with this time?

 

I'm not sure, you'll have to contact Doug about that.
