I have read maybe a year ago on this site the DETAILS on why hondata is considered a true standalone. I did not read it that well. I checked the hondata.com, but it does not explain much.

Anyway, my friends are telling me its not a true standalone and I know it is, just dont have any solid proof why.

Can someone do a small write up on this for me?
Thanks.

Im sure you meant "oh boy, you are about to get some good friendly responses with great info

some consider it a true standalone some don't. Its depends on the way you look at it.

1st- people say it isnt b/c you still have to use your stock ECU, and that would negate the term standalone.

2nd- people say it is b/c a piggy back intercepts signals and alters them, such as fuel maps. Hondata has its own maps and logs etc etc. so therefore its not a true piggy back.

so Hondata is dancing on the little redline between standalone and piggy back.

call it a PiggyLone

people who think its not a "standalone" are ignorant. it definitely stands alone.

Something I saved that someone wrote:
"Standalone Engine Managment": A microprocessor or discrete component based control unit that recieves all of its inputs directly from an engines sensors, calculates the necessary output requirements (on its own), and sends all of its outputs directly to the engines drivers (injectors, ignition module, VTEC, IAB, etc...). Standalone systems do NOT require any external components to recieve or send input or output signals, unless there are saleable options that can be added.

"Piggyback Engine Managment": A microprocessor or discrete component based control unit that modifys input signals to (or output signals from) a standalone engine managment system. In either case, a piggyback unit will not cause an engine to run on its own.

Now, I read the term "Hybrid" here in refrence to the Hondata system. That's fine for now. Just bear in mind that the Hondata box is not in the input/output stream and does not interpret or change the input or output signals. It does, however, provide the user ability to change parameters that directly affect the microprocessor calculations (IE fuel and ignition maps, among others). This leaves the ECU to run as a standalone unit.

The Hondata external box is connected to Denshikigens factory engineered IO port that originally allowed the Honda engineers to communicate with the *standalone* processor during program execution (for tuning purposes). Hondata played mix and match with the internal data map and uses this port only to protect the Hondata from being hacked. Call it standalone or call it hybrid.. I don't care. But call it inferior to any other standalone system for VTEC systems and you are a Fuc*ing RETARD.... PERIOD.

Go ahead (anyone) and name one other standalone system that allows you to map every ignition and fuel point for BOTH cam profiles at *every* RPM. You can't get that with the PMS, it isn't provided with the Haltech, and even most Motec don't deliver that kind of multicam support (at 5 times the price).

boosted hybrid

Very well put.

Thanks guys. Exactly the information I was looking for. I hate having debates with my friends since they dont know anything about our Hondas. They are all into VW's and Toyotas. But I love proving them wrong.

Ya happy now Mr 99%?

Some of you guys need to lighten up and quit being pansies.

Art...I was just talking about some local highschool ricers I saw tonight. It was a joke.

Yes, Hondata can be considered a stand alone. It doesn't require any external modifications (such as a V-AFC). Everything can be changed via PC software and written to the EEPROM.
