VT GTS Memcal

[benk]

Hi all

Have got a VT GTS here and was wondering what size the Eprom is in them so I can read the Bin on it
It is a a 32 pin Eprom

All the VT bins are 128k

Some of them are available in the bin archive. If you read it and we dont have it, feel free to submit it for inclusion, with the 4 letter ID code that'll be on it.

Read it as a 27c010

[benk]

It is in a car that has been heavly modified and has a real radical cam in it as well as high flow manifolds and heads. He sent the computer away to get modified and it is running real rich and stalls at idle.
On the chip it has CFZF CST1, I think it will be a modified CFZF tune with a Stage 1 tune what ever that is. The bloke that did the tune has closed down so I was going to have a look at it and see if I could read it.

According to Dr Bobs site thats a:

CFZF8259 $A6 5.7L Man 16234531 HSV 220KW 5.7L GMH V8 w/5spd

Its a $A6C so use the Yoda69's $A6C xdf from https://pcmhacking.net/forums/view ... 15&start=0

Also the realtime V8 Manual code that needs testing is $A6C if you wanted to try. You could suck out that cal from that chip in the car, swap to an nvram board and send it back in with no problems.

I don't have the nvram board that fits in these short memcal sockets yet but may have to invest in one shortly

If you can post a copy of the bin up, I'll have a look at what's changed and see what else may need to be added to the xdf.

Thanks,

Here is a copy of the bin. I don't know if it has been read right as nothing comes up with the $A6C XDF
I had to make up a new adaptor board for the the 32pin eprom so it is un tested yet
Let me know if it has been read right

[charlay86]

well the $A6C xdf worked when I opened it...

benk are you using tunerpro 5 to open it ?

i wouldn't be suprised if CST1 is something like a crow cam.
