OFT vs ECUFlash

[akyp]

I have OFT but I see myself getting a tactrix cable in the future, as soon as there's a good selection of LTE-enabled Windows tablets. The long flashing time of OFT gets old rather quickly. To do anything with the logs you'd need a laptop/tablet anyway.

Two things would concern me

Not all windows tablet run "full" windows some are a tablet version and Ecuflash may not run on them.

Also be concerned re voltage stability while flashing with tablet as it need to power the tactrix adapter, I always have mains power to laptop while flashing just to be sure.

nice idea though.

I think Windows RT is pretty much dead. Tablets running it don't normally have a full-size USB port anyway.

But you're right about stability. The latest tablets/ultrabooks only have one USB 3.0 port and no USB 2 which could be a compatibility issue.

I am a software engineer, so I don't mind a steep learning curve. However, this is my first sports car, so I am new to tuning. My primary goal is to learn as much as I can about tuning my NA BRZ.

As I understand it, both OFT and ECUFlash will use romraider for tuning, but I believe that there are differences between the two. Can you use ECUFlash tunes with OFT and vice versa? Is there a translation step to editing the binary files between the two?

I like the fact that OFT has off the shelf tunes that I can use as a jumping off point. At the same time, there are many books on tuning that I could use to start off with ECUFlash.

Functionality appears to be better in OFT with features like flat-foot shifting and other stuff like that. Honestly, I probably won't use any features like this as my main goal in owning this car is to become a better driver, but I just want to get the whole picture.

I am a hacker by trade, so cracking open the .bin in IDA sounds appealing. I could help out the community by looking for new addresses to edit and stuff like that. For that reason ECUFlash is appealing.

Price is irrelevant, so please don't take that into account.

Overall, OFT seems like the safer/faster choice, but ECUFlash might be more rewarding in the long run.

Based on what I have said above, could you recommend a tuning solution for me?
Thanks!

Off topic here but what does " a hacker by trade" do? do you work for a governmental agency?

Coders call themselves hackers because it sounds cool.

If you're a coder by trade, who's comfortable with disassembly, etc. why not come and join the fun here? I haven't had the time and energy to try and port the code over to the SH72531 processor environment, but I doubt it would be too difficult. When this code is available for the BRZ's very little out there could touch it - assuming of course you have a high affinity for fiddling with tech

You can use either device, I use Tactrix. Decision was mainly based on the fact that I was able to define (with RomRaider guys and Td-d's help) RAM logging addresses for my ROM before OFT had support for them, and I can apply whatever scaling I want to the parameters being logged.

I get logging of multiple parameters at 20-40Hz with Tactrix and process my logfiles in a batch quickly with MatLab.

For hacking the ROM, either device pulls a ROM file that you can hack. If you're interested in poking through this with IDA, I have traced a few things in the ROM - a lot of indirectly referenced info is quite hard to find (for me). KPIT GNU tools are also useful for seeing how the Renesas chips process the indirectly referenced code.

I previously worked as a government contractor. I am in the private sector now.

Most of the time that would be right, but in this case I mean offensive cyber security.

That sounds pretty fun.

So does this. Though I'm not sure I can give enough time to be terribly helpful. Lots of other side projects I am working on atm.

Ooh. Hahaha I get it now. Because for a bit I was interpretting it as him being just an asshole by trade.

Few things i have noticed is OP2 tactrix cable seems to be less reliable at connectivity. I have had it be troublesome to connect while OFT or ECUTEk connects fine. Also Tactrix OP2 can't log live. You can only look at what was logged after the fact which can't be dangerous if you run lean or start knocking. OFT is very slow at flashing but so is ECUTEK. OP2 tactrix is very fast about a min per flash.

I get 90 second flashes done on my ECUTek on my dated laptop. My OFT is 5 to 7 minutes.
