Has anyone had issues re-burning one of these chips? I'm using mptune with a burn2. Not sure if i'm doing something wrong or if the chips are wonky. It says "burn device write verification failed, please try again".

I've had many of them go bad. It seems like I've had a lot better luck with the ones I ordered from Boostbutton after I picked up a burn2. It seems as though My Willem unit wasn't as kind to them as it could have been. Of course, I've heard that there are a ton of knock off units that'll initially function, but won't allow for a lot of erase/write cycles.
i assume you've burned chips with the burn2 before? if not post a pic of the chip in the burner to make sure it's seated correctly. also, make sure the burn2 device is displayed in mptune on the bottom left of the screen.

I should add that I had a burn2 go bad on me a couple years ago. I went through all of their troubleshooting steps and they requested that I send it back in order to receive a new one. The CS was great.
Yeah i have burned the chips. I just got it all together, i figured it all out and burned my first chip which is a BB stage 4. I found that my idle is too rich so i adjusted a couple things and burned another chip. I found i needed more adjustment so I tried re-burning the first chip and it says that error. I tried re-burning the second chip just to see what would happen and I get the same error. I burned a new chip after that and it worked fine.
Get your 27SF512's from Xenocron. Anything from China is suspect. For a while, there was a cheaper version which allowed only a couple hundred re-flashes. So-called 'MTP'. Don't use those.
I got burned once, and from then I got all my chips from Xenocron.
I'll have to look when I get home. Bought them from eBay.
The chips from Moates are OK as well, right Rob??? That's where I bought mine.Originally Posted by ShelGame
I bought some from Moates, no issues so far.
I did get that verification error before, but it was because I had the chip indexed to the wrong end of the burner. DOH.
Moates gets them from Xenocron, so they should be fine.
From what I understand, maybe it's just internet lore, but Xenocron bought the last 'official' stocks of the 27SF512 in the DIP package. So, they are the only place to get them. There's also a place in Ohio (I forget the name) that has a bunch they bought from Xenocron. They sell for ~ $5/ea.
Basically, if you get them for less than Xenocron's price, they're probably not legit. They sell a 10-pack for $45. If you find one on eBay for less than that, I'd stay away.
This is what I have.

Fake chip, most likely.

Oh well. I bought 10 of them and I will just use em up and buy 10 real ones.
I really doubt you'll be able to use them. Good luck.
I've already burned 3 of them and verified they work in the car. They just won't let me re-burn them is all. 1 time use.
Same thing happened when I got burned. Basically, some of the China chips are probably OTP's (one-time programming) with a counterfeit label. You should be able to use them, once.
Glad to see I'm not alone with that. Although, I'm pretty sure I got very few or even one use out of some that I bought from Mouser.
Glad you guys are posting this stuff. I just ordered 1/2 a dozen chips & sockets from Moates so I should be set for many years to come...
I ordered a few from Moates also.
