Re: Question about Uberdata Ostrich
It is extremely simple...
As far as an explanation, what do you need?
All it really does is "pretend" its the chip in the ECU. The ECU knows no better.
When it makes changes, it waits until the ECU isnt looking at that spot when doing its calculations so nothing goes screwy.

Re: Question about Uberdata Ostrich
Ya, xenocron said it best... however, if you want a technical version, I can give you one.
The Ostrich plugs into the EEPROM socket on the ECU, and emulates the chip make up from rewriteable memory banks. I think it's got effectively 16 64K banks, 8 useable to Hondas without a daughterboard to switch the power output from the high bank and low bank. Basically like using a 512 chip to run dual programs. Anyway.. You can switch banks on the fly if your emulator application (TurboeDIT Crome Uberdata) supports it, meaning you can store multiple programs at a time and switch between them while the car is running, literally.
Ostrich waits until spare moments in the clock cycles and quick updates the bytes in inbetween those clock cycles. That is now the ECU never knows the code was changed. I've found in my tests with ROMulator and Ostrich, that ROMulator is sometimes too slow, and the ECU will catch it making changes and throw CELs. I've never had this happen with Ostrich. As a matter of fact, I've uploaded an ENTIRE ROM while the car running and it didn't ship a second. ...what's really fun (and dorky) to do is upload an entire ROM of 0x00 and watch your car drop to limp mode, then upload a good ROM and watch it come out of it... even better.. store the two ROMs in different memory banks, and swithc back and forth between them really fast.
But probably the most fun in real time programming is while you're tuning a guys car, and he's driving and you're at the computer.. change his rev limit while he's driving. Always good for a chuckle.

so when tuning you make changes to the .bin on the laptop and it will apply it to the ecu and when it is good you save the .bin and then burn the chip and put it in the ecu?
