help identify eprom chip (pic inside)

[Fast66691GSX]

Hey Everybody,

My 92 gsx i just got has a chip in it. The guy i got it from got it from another guy that can't remember anything about it.I'm trying to figure out is it a tmo or keydriver chip. I have a pic of it below. I am assuming the 8500 is the rev limit,the 6000 i guess is the nlts,but the 500 im lost. If any of you all know who manufactured this chip just let me know. Thanks

could be a keydriver chip

could be a keydiver chip

chances are its a keydiver chip, since the TMO chips are not made any more, Todd Day chips have not been legally produced for years now, if you see any on ebay, its a pirated copy

I'm pretty sure that is not a keydiver chip because it doesn't look like mine.

Mine says on the top line 78/55/AWD 11:1 KNO, and on the bottom line 850cc MAFT 92OCT.

It might be one of Jeff's chips or just something somebody else made and used a P-Touch label just Jeff and I do.

I don't think the 500 is the idle speed so perhaps it was intended to be a 5000 and the label was too long. If that's the case it's likely a very early DSMChip or a simple one somebody made up with a 8250 rpm redline, 6000 rpm clutch cut and 5000 rpm launch limit.

I believe at one point that ECU had DSMLink or was socketed at ECMTuning, that's where the label on the CPU comes from. I don't think Jeff was also doing them on ECU's he socketed.

I don't think it is mine, or at least not a legal copy. My labels usually also tell you what the gauge function is, what MAS, AFR targets, and even the octane they are designed for. It *could* be a very old one that Nate did for me, but it doesn't look like his labeling either. The only way to find out is to read it.
