yaTech1 (ElanScan alternative)

Postby Giniw » Tue 29.11.2016, 01:26

Hello Everyone,
It's been a while since I started developing my own ElanScan alternative, mainly for fun and also because I wanted to add a few things over the original one. Here are the main features I can think of:
– tested on Windows (7 and 10), should work on MacOS, Linux and Solaris too.
– real time graphs
– filter to find a parameter quickly
– more than two curves at a time
– more visible fault codes
– reset fault codes without deconnecting the battery
– reset block learn memory (BLM)
– reset idle air control (IAC)
– switch on and off the CEL programmatically (:D)
– idle air control manual override (by setting the IAC position or with a RPM target) — has an effect but doesn't work so well for now IIRC, needs more tests
– I don't know if it's just me, but I successfully dumped my ECU ROM with yaTech1 whereas it seems to fail with ElanScan.
– ... ?

(for your information, the tabs advanced explorer, performances tests and especially virtual dyno may be never implemented at all, they are completely empty so far)

PS: you may also notice that the version is already around 7 months old, I haven't had much time nor motivation to work on it lately ;-)
I will try to motivate myself to release a beta in a near future ^^

(Oh and by the way, the "About window" plays a couple of the Lotus Turbo Challenge video game musics — a very important feature indeed :lol: )

PS: of course all that wouldn't have been possible without the help from the ElanScan ini file, so ... Thank you for the huge reverse engineering work!!)

That's impressive and very interesting.

I have always been interested in having a mini computer monitoring the ECU installed behind the dash for general data logging and such. Having a system that will run on a linux machine would make this a lot easier. Perfect job of a Raspberry Pi.

I look forward to having a look at the Beta when you get time to set if free on the community.

Thanks :-)

I was thinking about developing a tiny specific version for an arduino (logs recording only) but I think the current version might work on a Raspberry PI without modification — I don't know whether it would suit the minimal requirements though.

Julien, nice work. Can you save/load ES (.ecu) file format?

It's not done yet, but yes at least the loading will be implemented (and xls/xlsx export too)
I reversed almost 100% of the ElanScan file format but when I paused working on that subject I was still looking for the usage of an integer which seems to be always set to 1 in all my ElanScan files — viewtopic.php?f=34&t=25409.

A Raspberry Pi solution would be great. Cheap and no need to lug a laptop around. Could probably be permanently mounted in the car if it had things like a pass through to the stock port, wifi or Bluetooth file transfer, etc.

Et voilà ! :D

I only tested if the opening of an existing log is working, because I don't have my car right here but according to the Serial library error message, I would say the logging feature probably works too.
Now I have to admit it is not the fastest piece of software I have ever seen but it is still usable in my own opinion, even for a large dataset like the one I used (around 30 minutes of logs).
And please keep in mind it's an old Raspberry Pi board that I borrowed, so it must be faster on a more modern one (I tested it on a Model B 512Mo if I am not wrong, please see https://fr.wikipedia.org/wiki/Raspberry ... .C3.A8le_B)
