hello. Just wondering what software people use to read/ write EPROMs chips for ECU chips? I've got a wellon machine which I use in my work to read/ write EPROMs in immobilisers to write in new keys when they have been lost.

I can use this machine to read the chip and write to it. I can also use the software it comes with to view the data but not sure if it is going to let me alter the data.

Is there a free software which can be used to change the data for changing say injectors or afm or that sort of thing?

Thanks

For 28pin chips you can use tunerpro program free download. You will need bin from chip and also bin specific xdf file to be able to read bin.
 
There is also Romeditor, it's very old. Tunerpro is much better!
I also have a burner and am slowly trying to learn how to use the tunerpro software.
Although I always wondered what razza and keydiver etc used back in the day.

Same as what I use. Moats hardware for writing and TunerPro.

Ahh I didn't know tunerpro was out back then.
Ostrich 2 came out later and tunerpro rt so you can live map trace using the two. Made it so much easier to pin point what cells were used at the time. Still, nothing beats the evoscan logging and live map tracing.

Thanks guys. I'll check it out. Is it pretty straight forward or something you need to learn?
There doesn't seem to be much guidance available on it, you just need to spend some time and learn it I guess.

I believe (and Mio or Razza could probably clear it up if I'm wrong) but it all comes down to creating the definition file as to what you can/cannot do with the .bin.
Depending on what car you have, there might be an existing definition file loaded up on the tunerpro website, with which you can change basic things like injector sizing and MAF compensation.

Although I'm not sure how you would accurately change the VQ map for a given MAF. - I was thinking of this the other day, maybe you could first determine what profile wave the meter outputs and then use a signal generator and inject variable frequency input whilst monitoring MAF voltage output but I never bothered with opening a MAF and trying to figure out how to do it. 1
I'm not sure how the big boys do it (if anyone would like to explain that'd be great).

Here is a link on creating the .xdf (Mio is THE MAN for any questions here :thumbsup: )

So you connect the ostrich to the ECU, a USB-RS232 converter to the OBD1 port and run tunerpro/evoscan simulataneously?
Do you make the OBD1-RS232 cable the same as you would for those old palm pilot dataloggers?

You actually conect ostrich to laptop usb and open tunerpro. From tunerpro you conect to ostrich and then you can live trace the map in tunerpro.
