eprom programmer,what to do

[virus1976]

I appended I too am hoping to give a useful contribution to the discussion by bringing a bit of the tests made both on the job and with friends on some of the programmers that are on the market

top3000/3100

On paper they seem to have good potential? (40.000 unit? supported), but in practice are of disasters.
The software ? partially in chinese (the lesser evil),several of the unit? listed are not supported, the manuals ? totally absent, the Test IC is not working.
In any case, I've had problems with the ZIF.


Genius g540
? was one of the first programmers usb that I had and can I say that ? very reliable, unfortunately, not ? pi? developed and has a park unit? very limited.

GQ-4X
the laboratory use and does what it says ? always well-supported and for what it costs it is worth to buy it

wellon vp190,vp280,vp380,vp480
you can easily find around are reliable and support between 14,000 and 32,000 out unit? but they are now models out of production, especially the first 2.

wellon vp290,vp390,vp590, vp596
have replaced some older models do not have excessive costs and to cover abbondantememte the normal requirements

Wellon gp-1(gp-10)
it is part of the high-end programmers, the gp-1(version for european markets) is to be found for affordable prices, has support of about 32,000 units.

Regarding the Wellon around there are several models with acronyms strange type vp498,vp908 etc are clearly of the buffaloes, they are often older models with the casing changed

Xeltek superpro 500P
I have the version with almond-shaped eyes, never a problem, even if there are some things (like the usb connector and power connector) welded to the good(that you can't? have everything).
Supports nearly 43,000 units? and a documentation of all respect, there is, for some time the version 600P pi? fast and with some unit? added but I don't think the cost justifies the purchase.

Conitec GALEP 5
The use in the laboratory for about 2 years and ? infallible coast of pi? of the other but ? the one that has by far the best support hw/sw.
also available are (always produced by conitec) a series of brackets and adapters for the reading of the majority of the eprom/flash etc.

to begin with the g4 goes well then when one wants to continue you know the things to buy are never-ending depending on the work you do....

From my experience I advise you to first of a upa, then another recommended by colleagues, for gq to ****s e2p I was a little disappointed not to act in 16-bit 93lc66 ciai and good work.

[maxsek]

I work with gq4x and upa, and I am fine..the 29f200 or 400 do that with the gq4x with its adapter and never have problems

[scinti]

I think I've only said that the gq4x does not read the e2p in 16-bit I also use adt to read the 29f200 and 400 hello.

[sportknight]

to work on a 75 with a 27c256 I saw that the tl866cs ago but which adapter should I get?

[klajdin]

Sorry that I may have missed some of the post but the GQ-4X the 29f800 the ago with no problems ?
.. if it's so? it will be? my next purchase !

[legendaryslave]

Without problems

[klajdin]

Without problems

Thanks , I took a chinese complete with adapter but not me, the reading seemed good but the writing was a mess, you know, even if he has a guide on how to proceed with the read/write memories ?
I do not happen to use it all day for? I ? served pi? a time, and expense ? fairly contained.

[sportknight]

sorry guys,I finally got a wellon vp390 and sincerely, using it to 27c of the 75 I had not had problems.
A few days ago I had read a 29f400bb a sid 305,I am going to read, and no,I do not read the contact of the first pin of the flash.
I want to put the memory on the ecu believing that there has been no consequences, and instead, the ecu blocked.
fortunately rewrite the file in serial, and the car starts again.

yesterday, however, 29f400bc,same problem

the flash is 44-pin on two sides with adapter 44sopzif

I checked all the welds and they are ok both on the programmer and the adapter
