Hello everyone. I work in a shop in NJ and have slowly been teaching myself the necessities of electronics over the years.
I think I'm more dangerous than anything else, but I'm at a point now where I need to start doing a lot more reading and trial and error. I've been able to successfully understand how to modify a Honda ECU and write a basemap to a 27ST512 chip. Which in itself was a huge feat for me, because I have always been perplexed by the electronics world. But now I feel a little more confident and want to start with something and try to complete it.
I want to learn how to read an IC chip, save the info written to it and write it another IC chip. The specific task relates to the tachometer on an instrument cluster. I purchased a GQ 4X4 and was able to read the 27ST512 Chip, and perform other basic checks. Blank check, etc. But now I am having a hard time identifying the chip that transforms the signal from the ECM to the tachometer. The chip has HML 087 8645 written on it and plenty of Google searching hasn't yielded much.
So I am hoping I can get some direction/assistance here.

Also, I would love some suggestions on reading to help open my mind up about this type of learning.
