View Full Version : Chip offsets and buffer offsets
08-11-2011, 11:00 PM
I have a Moates AutoProm and trying to read a Memcal chip from a 1993. Can't seem to get the chip and buffer offsets right? Anyone know what to set them at?

OK Does anyone know what mask ID a 1993 Chevy 7.4L Auto would be?

What's the PCM #?

If it had a sticker I would know? Was there a varity that year?

I looked at the ALDL Stuff files, looks like there was 160 baud (A106) and 8192 baud (A138 and A??? for the trans).

It's a P4 with Memcal not a chip... freind brought it to me to delete some things but I have never been able to read it corectly or don't have the correct mask? I have tried $OD. $OE, $31, basically all the EXCELLENT XDF and ADX you made! Of which has brought me much joy! Really! Thank you!
It's a Hypertech aftermarket Memcal that has the chip in an adapter like the Moates G1. Is there another mask? I have no problems reading other 427/395 chips? I would say maybe the chip was burned wrong but it runs fine in his truck? 1993 454 TBI auto...

When you say that you can't read it correctly, do you mean that you can read some of it? The masks that I worked with all shared a common "Mask ID" location.

Yeah I get hex and even correct size but when I look at it in TunerPro with XDFs the numbers are all wrong. I'm not very hexidecimal but could look for mask ID if I had a specific address? Just got me stumped?

L4008 is the address for $E6, $0D, $0E, and $31 and I believe this is used for some of the other masks as well.

Have not had time to dive into this but found it may be a $85 which could be the problem the whole time. Since theres no ads or adx it may not be worth the effort.
