My EPROM programmer is an old parallel port job. It works okay, for what it is, but I'm starting to worry about the integrity of the computer that I've been using to burn chips. Time to upgrade the laptop and (since nothing has a parallel port any more) the programmer.
So... what are you all using to program your EPROMs. I don't care anything about doing flash programming or other "on the fly" stuff. Just a simple USB programmer will do.
Moates burn2. Cheap and works. Good for minor changes. I want to upgrade to an ostrich emulator. I find myself making constant changes. I didn't anticipate that getting into this

It looks great except that I still want to be able to do 2732s, and this one won't. But it's definitely a possibility. Thanks!
I am using a Genius G540 eprom/flash USB programmer. They sell on eBay for $45 shipped which is a good buy. Its Chinese, like everything else electronic these days but it works. For editing eproms Tunercat is used. Good equipment and program for 80's GM tuning. For OBDII it doesn't get much better than HP Tuners that handles all OBDII applications that I have tuned.

Thanks guys! I saw several of those online, but knew nothing about them. I appreciate the recommendations.
With that said... I'm amazed at how the prices have dropped. (I thought that PROM programming was a dying art. Perhaps not.) My last programmer (the parallel port one) was over $100, and it was really "bare bones", and not that reliable. It worked fine when it was new, but after it had gotten a bit older, it needed to "warm up" for a couple of hours (seriously) before it would read/write reliably.
Okay. Just ordered the GQ-4X. The other was tempting (especially at half the price) but it specifically spelled out a 32 bit OS, where the GQ-4X will work with 64 bit as well. Thanks again.

I have used the Genius G540 programmer with Windows 7 w/o problems. What operating system are you using it with? It seems to program all 2732A , 27128 and 27265 eproms well. Haven't tried it on flash memory yet but can't imagine a problem programming those.

I have only used it with Windows 7, and no issues. I upgraded my computer to Windows 10, but haven't had a chance to try it yet. I don't expect any problems. Having said that, I'm thinking of going back to Windows 7 anyway. Really not a fan of this new OS.

I'm using Windows 7 as well, but mine is 64 bit. The G540 specifically spelled out 32 bit, while the other mentioned 64. Otherwise, I'd have probably gone with the G540, if for no other reason than 50 bucks is 50 bucks. Thanks! (Got an email. The other one is in shipping, already.)
Here is a review of the Genius 540 that I found pretty funny:
[b]•GENIUS G540/G840 universal device programmer - It caused amazing problems simply trying to program a PIC16F84A. Also it has the manual from hell!
Do not even contemplate this programmer unless you are a native Chinese scholar and can locate the original manual. The 'Engrish' one is practically useless (Ian.M) [/b]

He said Engrish....
My Engrish is great, so I had no issues.
Not really sure what his problem was ...there really isn't much you have to do with it. Took me about 15 minutes to figure out everything required. No issues reading chips, or burning new programs back to them. Perhaps I'm a native Chinese scholar and didn't realize...
I've been using a Sivana Wellem Pro. They're all Chinese now. I've read 27c128 and 27c256, wrote 27sf256, some serial eeproms, and one on my motherboard. Came with adapters for plgg32 and a few others. The only problem I've has wasn't with the programmer as much as with older Eproms. A lot of them don't have the true manufactures on them. The one for the 1993 3800 PCM had to set to a Phillips 27c256 to read it. It is a little picky that you have the right manufacture when reading. I'm glad the software that came with it had a boat load of options.
One thing to note is that the 2732 eproms came in two different versions, 2732 and 2732A that used different programming voltages. If it is not set right on the programmer, the eprom will not program . On later eproms like the 27C512 that is used on the Cadillac 4.9L OBD1 ECM you can substitute the easier to work with flash memory 27SF512 You will need to unsolder many connections and alter the memcal for a socket or use the Moates memcal adapter to be able to plug it in. The pin outs are the same.

Gotcha. The programmer I have had for several years (that I am replacing) actually has three programming voltages for the "2732 series" chips, depending upon which version you were programming. It was always a bit "sketchy". Sometimes I had to run the voltages up higher than was called for, in order to write to the chip. Of course, that was usually the last time that chip could be programmed. (In itself, a good reason to replace the programmer, even ignoring the previously mentioned parallel port interface.) All of my 4.9 chips are 27SF512s. I never had any issues with those, other than the flakey programmer. I soldered a socket into the MEMCAL.

I'm a newby at doing this myself and haven't bought one of these yet.
Question: Can you use these EPROM programmers to make a simple copy of the existing chip you already have in your OBD1 ECM? I'd like to make some backup copies of the custom one I have should the chip go bad. Do you need software to run the programmer or to copy the chip?
Any required software will almost always ship with the programmer. It's easy to copy a chip. You just read the chip and save the file. To make a copy, you pretty much just plug in a blank chip, and program it using the saved file.
Some may do direct copies, but I doubt it. At least the cheap azz programmer that I had before wouldn't. Still... it isn't that hard to do the "read, save, program" thing.
[This message has been edited by Raydar (edited 12-05-2015).]
Making copies isn't a problem. Making any changes requires you have an editor and a file for that ECM that allows you to decode the hex information into something that you can read. Unless you know how to read hex decimal and know what the addresses for the changes are and what number is expected. Tuner pro has a good compare feature to make sure your copy is digitally the same as the original.
So I know this thread is a few years old, but is anyone here able to program changes for me? I have a 3800 SC series 1, with 4T60E auto that came out of a 1995 Buick Riviera. I'm doing the F40 6 spd swap. I also have 3 extra EPROMs. I only need one changed. GM part number is 1#16204419 Or, can you recommend someone? Thanks, Kevin

If that ECM uses eproms and its not flash based, the 95 3800SC might be the only series II that used OBD 1.5. All of the other 3800SC's use OBD II. If this is true, it would surprise me that GM did not do the change over in that model year. Assume that this is correct you need to find someone that has the editing file for that specific one year ECM program. The later OBD 1.5 ECM's employed a memcal where the eprom was soldered in and it unfastens as a unit. If your computer has one of these Memcal's then there is no separate eprom socket and I recommend that you purchase the Moates adapter and a zif socket. This will make memory chip insertion and removal easy. ------------------ " THE BLACK PARALYZER" -87GT 3800SC Series III engine, custom ZZP /Frozen Boost Intercooler setup, 3.4" Pulley, Northstar TB, LS1 MAF, 3" Spintech/Hedman Exhaust, Autolite 104's, MSD wires, Custom CAI, 4T65eHD w. custom axles, HP Tuners VCM Suite.

I was running a 1993 Series 1 that had a 1995 charger on it. Through all the reading that I had done the 1995 3800SC was series 1. Although the N/A 3800 was Series II. The 1994/1995 3800 SCs had the later gen 3 M62. Epoxy coated/ tighter tolerances. But still M62. I have to admit, it was the smoothest 3800 that I have run. Unless you have a UV eraser, you can't edit the stock proms. Only read them. Even with a UV eraser, they don't like to be rewritten. Highly suggest a EEprom like SST 27sf512. I have been using the 256 version and have been able to rewrite many times. The 1993 PCM that I'm using uses the above mentioned "memcal". With soldered in prom. I had to rape a memcal to make an adapter that I soldered a ZIF socket to. It was a pain. And suggest using the mentioned Moats adapter. Much easier and cleaner. The memcal also has calibration chips on it. Supposed to be for "limp in mode". But have found if the prom is not read properly, it won;t run anyway. Also you may have a hard time finding a base BIN and exchange files(different tuner software uses different names for it). Tuner Pro uses XDF. GMEpro(dos) uses EPE. You can read the stock prom for a base BIN. I'm using the 16141470 PCM. Even though it is much more popular than the 1994/1995 3800 PCMs I have found a few issues with the Tuner Pro XDF. Mostly with the SC timing tables. Some of the values would be entered wrong.

Ok, most of this is way over my head. But to clarify, My EPROM is a plug in and not soldered in. I do know the PCM is different in the Riviera from the Park Avenue because the guy that made up the harness simply did it as a Park Avenue and it didn't work. The harness for a park avenue doesn't use a red wire from the MAF to the computer. The harness guy removed this wire from the computer plug and simply taped it off. I tried for weeks to figure it out and finally bought the service manual, $160, for the riviera and after looking at the wiring schematics knew there was no MAF red wire. I un-taped the wire, plugged it in and it worked. I have no idea why he would do this but it caused me a lot of headaches. I believe my engine is OBD ll. I have a Tech 2 scanner that works with it. If I can't find someone to burn an EPROM for this I'll had a lot of parts for sale. Kevin
Any one ever use a usb programmer that can do TI 2532 chips? Radar will yours do that? as I can come up with a pc with parallel port, just to program those. I have a stack of those and would like to program them.

Unfortunately, your ECM is OBDI, but the stock installation used an OBDII style of ALDL connector. It's confusing, but GM was in a transition period. Many of the Error codes, etc in your ECM are OBDII style. You're lucky if your scanner will read it. I finally tracked down an OBDI scanner that would almost work, but the Riviera is a real oddball. It does use the same ECM as the Park Ave / Bonneville / TransSport- but of course the PROM is programmed differently. The ECM is known for failure. I pulled 4 from the Pick and Pull, and they were all Rebuilt ( so the original had failed).
As I mentioned in your other post, Ryan at Sinister Performance is the man to go to for this programming. If anyone can work it out, it will be him. sp1@gmtuners.com

me personally, i keep an older nItel Xeon industrial PC computer, ( small mainboard ), with a parallel port on it out in the garage, thats where i do all my programming. i have it dual boot for DOS and windows XP, because i have some legacy software that i use that still runs in a DOS environment for OBD-1 stuff, and won't run inside a windows command prompt . My programmer is a Willem programmer, fairly versatile, programs the full range/spectrum of proms
I have only used it with Windows 7, and no issues. I upgraded my computer to Windows 10, but haven't had a chance to try it yet. I don't expect any problems. Having said that, I'm thinking of going back to Windows 7 anyway. Really not a fan of this new OS.
same here, hate windows 10.. ive given it a go on 3 separate ocassions, each time, using it for 3 + weeks... the 3rd time, i even downloaded that windows classic app trhat setups the functionality of the OS to look and feel like windows 7, and i still nixed windows 10 , wont go back to it.
our old paraleI burner has seen better days. Thus, I'm going to buy a Genius-G540-USB-Universal-Bios-GAL-Programmer to burn some custom chips for my very modified NA 87 2.8 and my 86 turbo 2.8
That said, we lost our file listing the parameters, such as; rev limiter, ign adv, EGR-off, decel lean-off, add x%? fuel, etc etc. if someone can send me such or advise where to find it, i would appreciate it very much. thanks
I now have a G540 and cannot get it read chips or do much else, I keep getting the same error: illegitimacy user ID detected MY SON TRIED TO BURN CHIPS ON HIS SYSTEM, BUT COULD NOT READ ANY. DID THAT LOCK THE DEVICE TO HIS SYSTEM? DOES THUS MANUFACTURER HAVE A SUPPORT SITE?
