2J74Y

[Darren_W]

Hello Forum.

Is there a trick where another mask could be used for 2J74Y ?

I can't buy good parts every source I have found are selling me rubbish.

Any alternative info or good supplier would be helpful.

I have genuine ETL HC08 tool.

Hi! Are You using this chip for audi instrument cluster repair? Where do You buy chips and what is wrong with them?

Hello.

I'm from England.

I get stuck with EIS repairs, I did get stuck one time with Audi cluster, this time I had a used part

The latest China parts i have will not link with ETL.I get over current error with 5 pieces.

Previous pieces 2J74Y & 4J74Y erased, did write procedure at the end failed and lost connection.

I never managed to buy high-quality chips 2J74Y in China. They for 99% sell the unknown relabelled chips. You can try to buy the chip 4J74Y, but there will be the same. It is better to buy here http://codecard.lt/electronics/2j74y/mc ... d_130.html .

I agree for 100%
Couple times I bought them here, had no problems, too.

Thanks for the input guys.

Does using 4J74Y give good results?

I have these that are no good also.... after writing they die.

If to buy in China, the result can't be predicted. In 90% of cases result negative. I will repeat once again: buy chips in Europe from the checked seller. Also will be all right!
And about masks of processors - you look in ETL or, better, datasheet - the memory size, address vectors, etc. We not "invent the bicycle", we take the serviceable chip, we program and we establish.
