for about the past 5 years i have wanted to get into chip tuning ( reading, understanding, reprogramming of eproms) it started with my 92 chevy 1500 sport truck. i downloaded programs and did research on it all but never pulled the trigger on any cables or readers/burners.

so i have been looking into it a bit more lately.
not trying to step on any ones toes such as 034 or ben swann. i respect what they do.
but i would like to learn as well.

when the hyundai genesis first came out i was big into the thread on one of the forums that they were trying to make progress on cracking it for self tuning.

i would like a usb based reader/burner
i run windows 7
would like to read and write chips for 10v 5 cyls and my v8.
i found a few universal eprom/eeprom readers on ebay for pretty cheap. but i dont know what i want for what i want to do.
yes the v8 is already chipped with the abt chip. but i like to tinker with things.

i also understand the risk of hurting/blowing things up with doing this.

any one else on here tinker with this and have insight? suggestions? definition files ?etc?

Mr. Swann says you want to get an eprom burner that also checks the burned data afterwards. It's the only way to be certain and sometimes the burned data can be glitched.

before you bother stepping into chip tuning, get lots of experience tuning standalone systems. The hard part about chip tuning is getting a decent definition file built for it so you have control over enough of the relevant maps. the hardware tools is the *easy* part when it comes to that stuff.

Thank you.

I can understand the understanding the stand alone systems first from the tuning aspect. But aren't the methods for programming and writing different? Like megasquirt for example. Isn't that a re writable setup. Plug it in. Reflash it and go? Vs pulling the chip erasing and re burning?

yes and no.

When we build motronic maps we start with an emulator that allows us to tune the stock boxes real time. we then use the burner hardware to produce the final chips.

I'll reiterate though. the method of burning (be it emulator or physically burned chip) is the easy part. its useless without a very good definition built of the maps.

Well, it is kind of a chicken and egg thing. If you don't have a reader/programmer, you can't get the data off the chip to start with. If you don't have the map and CS info, you can't make useful changes. If you haven't done that kind of thing before, it really isn't the place to start unless you are a glutton for punishment. Personally, I wouldn't bother with learning the old Audi stuff. BTDT, and compared to all the new stuff, there just isn't all that much you can do with it and it is a PITA when you start out. With the old stuff you really need an emulator to do it right, especially on the early Motronic ECUs.

Like Marc said, if you really want to learn something useful, go with a stand alone system or (IMO) a newer say ME 7 car like a late 1.8T or 2.7T. There is no need for an emulator or burner in most cases, and tools are dirt cheap. There are places where you can find lots info on the newer systems with tools and BTDT support from others. If you seek, you will find.

I appreciate the input... but I currently have three type 44 cars.. my daily. Her daily. And the toy.

I don't want to buy a " new" car just so I can start tuning it. That's not what I'm after. I want to mess with what I have.

As per the chicken and egg thing. I get it and that's what it feels like. ...

mc era stuff may be dumb and old but it works pretty well and has knock sensing. If you get good at it, I think that you could maybe make it work with custom, extended maps for a dizzy based 20vt. then just add a seq fuel only ecu for fueling and you would be in pretty good shape.
