What advantages does basic hondata have over a safc? I dont care about all the datalogging, launch controld and all that bs. Just talking basic tuning. Can a SAFC run a turbo car safely at 14psi?

well hondata can control ignition timing and things like that. all the afc can do is change vtec point and add/remove fuel

Its a true standalone. SAFC is just a bandaid piggyback. Hondata is more precise.

I'm not sure with the hondata but with the safc you can only add or subtract fuel in 500rpm increments. I believe you can make adjustments in 100rpm increments with a true stand-alone like hondata.
With hondata you can make timing adjustments as needed (precise) instead of retarding your timing using the distributor which causes power loss. If you have the funds hondata is the way to go, you have more control over the engine, it will in turn run safer.You can also run larger injectors with hondata as where with the safc you pretty much limited to 450cc or smaller.

its all about tuning.

the hondata can tune your motor better than the safc.

One day...I too will have a Hondata

how is hondata a true stand alone when you keep the stock ecu?<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by intekragsr &raquo;</TD></TR><TR><TD CLASS="quote">Its a true standalone.

So you can only run 440cc or smaller? Will that be enough for 14 psi on a 1.5 sohc with a t3?

Mr Hammond

It just uses the stock ECU as a platform. Comes with it's own base map's etc... The advantage of Hondata are tuning of partial throttle maps, timing etc... So you can tune the car and still actually drive it in rush hour traffic for an hour to work and it won't idle like garbage and you can still get 20+mpg.

"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).

lol, where did you get that from?

FastNFurious

I believe the AEM EMS can do that also

evoeone

thats your opinion, i still keep thinking its a technically not stand alone, but its a great product, hybrid yes,
