Me and a tech. friend found this Programmer but was skeptical about the price. He ordered it and got i in the other day. He has done quit of bit non-stop tunning on his 355 Vortec TPI and hasnt had one problem yet. It shipped from Thailand about 1-week before the Tsunami. It was only $40. Cant beat that with a stick. Heres the link. I did a few searches on here and found nothing previous about it. So i hope im not re-posting the same subject.

$40 Eprom Programmer

 

I didn't follow the link, but this is a Willem unit IIRC.

Have a look at http://www.willem.org/

These are not as straightforward as a PPII IMO.

This EPROM burner is acutally used to burn ANY kind of PROM, not just EPROMs. It will do BIOS chips, and many other things. It isn't very user friendly, but After one or two trial and error on setting jumpers, I have been successfully burning EEPROMs ever since.

Now if I can just figure out what i'm doing on my ECM, i'll be good.

 

It's also a total ripoff of the actual Willem unit. The Willem unit was designed around an open-sourced DIY approach. These folks, along with some others, are mass producing the design and giving it away to make money on the volumes.

This is another example of HongKong swooping in to cash in. I asked Willem about it, and he said there's really nothing he can do. Sort of like the deal with the SPEP clone-unit and the Xtronics originators on the PocketProgrammer.

But hey, it's cheap right? Anything to save a buck.
(channeling Bruce in his absence)

 

For tuning 1 car that's probably the best route, for doing multiple chips sizes the PP really does save time. And if you have a USB port and don't need to program the old ccc/TBI/and early TPI 2732 chips then bo with moates Burn1.

 

At least the kit can be had as a DIY kit so some bucks can be saved and people can LEARN from it. That is a lot more than some of the electronic offerings that are PUSHED on this board.

 

Thats my guy there. Whats going on Thomas. When did you become a member. Finally someone on here thats local to me. Tail can tell you more about it.

 

I didnt know about http://www.willem.org/ . $47.00 isnt bad either.

 

Ok, now I'm officially confused. I'm looking for a cheap setup to burn chips for my 1987 MAF TPI setup, retrofitted on a 327 engine. I had someone burn me a chip to get going, but I realize it's going to take quite a bit of work to get all of the small driveability issues resolved.

What Willem programmer should I go with? The 4.0 or the 4.5? It looks like I need the 4.0, as the 4.5 does not support serial EEproms. Will I need any adapters to plug the eprom from my 1987 MAF memcals into the programmer (I assume I have to desolder the eprom from the memcal first)? Aside from a programmer, a UV eraser, any necessary cables, spare chips, my laptop, and software to edit the bin files, do I need anything else just to burn with?

I'm a mechanical engineer with a fair amount of DIY electronics experience and excellent computer skills, but all this EE techno jargon is lost on me sometimes.

Thanks!

 

The 4.5 version does everything the 4.0 does and then some. It just has added features from what I see. I don't know that you need the ability to do 8M PROMS, so the 4.0 version is probably more than enough if you are only going to use it to burn EPROMS for your car. Also, I would recommend buying the Eraseable EPROMS (or EEPROMS), 29cxxx (if your chip is a 27c256, you'd want the 29c256) then you don't need a UV eraser. Little more expensive of an EEPROM, but without the cost of a UV eraser, cheaper overall. I use the 29c256, and it's fast and easy. Takes about 45 seconds to erase, burn, and verify.

 

Tail, thanks. Do you have the 4.0 or 4.5? What jumper settings did you have to change to get the programmer set up for our Eproms (I will go with the EEProms on your suggestion)

 

So Willem's product would be a good programmer to begin burning for a Lo3, or not? I thought be in high school and knowing some technology would help me, but I am starting to not understand as well.

 

The software pops up and gives you the correct jumper settings. Pretty easy to figure out if you are fimillar with the consept of jumpers and dip switches. I'm using the rip off version (unknown to me until this post came about). I am using something similar to 4.5, but mine also had a USB connection to obtain power instead of requiring an external power source.

As for the ripoff burner, i obtained the link from the gmpcm website. I was just cecking all options on bin editing software & the idea of a $40 eprom burner was appealing, even if i had to order it from Thiland. I'm sorry & wish I had ordered the real Willem from the US. Hindsight is 20/20.

 

Not sure what you mean by an Lo3, but the Willem burns everything the pocket programmer does + proms for PCs, other electronics, etc. For some other types it requires adapters (actually I think the 4.5 version of the real Willem has one or two adapters built on). Just find the specific type of PROM you want to burn and make sure it's on the list. You should be able to download the software which will have the list of PROMs for you to select (mine has hundreds of PROMs). I know that my burner will not only burn the standrad proms, but also burns the extended ones used in makeing a multi-bin prom.

That figures, doesn't it? Not your fault. I guess it's OK for HIM to have links to pirated copyright material, right?

 

Duh, LO3 motor. Man, i need to be smacked. Yes, the Willem will do a chip for that. All the good old style.

As for the PROM, I had found a Matrix somewhere on the PROM code and what kind of chip it was / what kind you need to order, I just can't seem to find it now.

this may get you what you need. According to it, the 2732a is a 4Kbyte EPROM. EPROM number is well, 2732.

Wow Craig, you said it. Makes one wonder where people like him come from.

RBob.

 

I ended up ordering Burn1, some EEproms, and a zif socket last night from Moates.net. Might as well support our own here.

 

I bought a Willem unit last night. Wish me luck, sorry Moates, however I might order an adapter in the future after I give these 2732 chips a run.

 

The Willem is a good unit. Many folks have good luck with them. If you're going to get one, just get it from www.willem.org to support their cause.

 

so what are the advantages of the xtronics pocket programmer to the willem one? Is the xtronics a lot easier or something? I'm wanting to try burning some chips for my iroc, but $150 is a bit expensive for just goofing around, however, if everything goes good I want to be able to burn chips for budies cars and burna chip for the 350 I'm building (not gonna work at all on a stock chip)

 

$150 is alot better then 300 for a custom that isnt going to be the way you want it anyways.

 

I wouldn't even consider a jet chip, even when i was first getting into cars i knew they were total b.s. and there was no way I'd spend 300+ on something that is just going to alter spark/fuel.

I'm just saying right now My iroc is the only tpi car i have (made my bird carburated, and don't have the tpi on the '79 yet) so right now it would just be for learning, BUT I'd want to be able to burn a lot of stufff W/ it in the future. I don't like buying stuff to do the same job twice. If it's simply not as good I'll just get the pocket programmer, but if it'll work fine W/ ALL tpi cars (85-92) and isn't that much more of a hassle than the pp, then i could probably order one with some e-proms tonight/tomorrow, and start messing with chips by next weekend.

so what exactly makes it not as good?

 

I have a willem that I purchased from www.willem.org a couple of years ago. It works fine, no issues whatsoever. The only thing is I'd prefer a programmer that is enclosed rather open to the elements like the willem...

 

same here... been using my willem for well over a year... no issues, works great...

 

So has anyone decided on a good willem setup for the novice/beginner programmer? The 4.5 version should be fine for my 7747/ LO5 right? Which were the chips that dont need an eraser? Id like to be able to just erase the chip right there instead of spending the $30 on a UV one.

I forgot to ask if those willem setups will work with RT programs?

 

EEPROMs are erasable. I use the 29c256 (for the 730). I am not sure about the 2732 prom.

 

Where can I order the 2732 chips?

I guess, by looking at the site, I have to send an email to Willem to buy a programmer? And the 4.0 is good enough to burn chips for the L03 305?

Thanks

 

This may not be the case anymore (haven’t looked lately), but you may want to double check if the newer versions are able to specifically write 21 and 25V eproms. It used to be that only the ones with external power suppy connections (not usb powered) could.
