Wondering about modding the stock tt ecu, similar to the V8 mods that were going on a while back. Whilst I've tried searching, it came back with very mixed results!
Also wondering, seeing as I have a friend who is VERY cluey with all thing electronic (her 1st job straight out of uni was at Saab aerospace designing the new missile frigate guidance systems!), would it be worth while giving her a tt ecu to play with, or did toyota make them so un-moddable that this would be a fruitless task?
If answers could be limited to what has been asked, rather than pointing out that to do INSTEAD of this, that would be great! If I ask her to do this (she is rather busy) I just want to give her as much useful info as possible.

To much involved, this chick could re-write the xp code in her sleep, and she actually ENJOYS working with surface mount gear!?!
Hmmm, what's this idea you speak of, sounds rather exciting! Or is that about as far away as those undertrays are, hehehe? On that note, where do you order them from? If they are only the price you emailed to me, I'll get some soon and start working on them!!!

I swear you have the biggest sleaves ever Neil! Sooo many tricks waiting to come out If only you had a team of little Neils, and an endless bank account....

The big problem is getting data on the ECU chips. No circuits or data exists as far as I can find out. Reverse engineering is possible but you'd need to do a lot of data logging and such with the ECU in the car and the car preferably on a dyno. It is not too difficult to guess the functions of most parts of the circuit but this is only generalisation and you really need to have specific data to mod the things. Some stuff, like modifying sensor outputs is relatively easy but you can never be real sure what the ECU will make of the modified sensor data. A dyno, multi-channel data logger, logic analyser (the $150k variety not the cheap ones) and other measuring gear like storage CRO, Air/Fuel ratio meter, fuel flow meter, airflow meter and heaps of time would really help and then the results are not certain. A code listing straight from the Toyota design department would really help.
I had a bit of a go with the V8 ECU when I had the entire resources of the ANU Physical sciences labs and didn't get too far. I know a bit about how they work generally but the one thing I didn't have was a dyno and without that you're stuffed as most of the gear needed to figure out what was going on couldn't be lugged around in the car and the interesting need-to-know stuff only happens when the car is being driven.
The one thing in your favour is that the TT ECU is a lot less complex than the V8 one and seems to follow a more conventional engineering approach.

Simple, we'll grab Neil's S-Cargo and take it to her work, load it up with all the goodies and go to a dyno tuner. I'm sure they won't mind us 'borrowing' defence force testing equipment for a while
