Hi guys, I read the prom that was in my car and a Hypertech chip that I was given on my Burn1 to look at the data and everthing is 0's,when I try to look at it in TunerPro RT, no data. I bought the HDR1 to read the prom that was running my last engine since the late ninetys. I purchased my SuperRam and 219 camshaft from Lingenfelter in 96 and they directed me to a man in Tampa, Jim I think, and I wanted to look at his tuning and maybe use that for a starter bin file for my new build. .I read each chip with Flash and Burn and after seeing success in the box I saved each buffer file. What am I doing wrong? Thanks in advance..

 

Is the hdr1 inserted correctly. Some Hypertech shave 2 unused holes on the front so the spacing of the hdr1 needs to be back one hole. Read as a 27c128 .

 

Yes its seems to be correct. The Lingenfelter prom was put onto the hdr1 and the hypertech was taken out of the holder and put straight into the burn 1 with notch toward handle and open slots at the top toward handle.

 

The only thing I can think of is the offsets are wrong.

 

For the 2732A read only chip the addresses are chip-000000-000FFF and buffer 000000-000FFF,.I get Prom I/O succeded and Verifacation succeded when I do it each time.Bytes written are 4096

 

That’s correct but I thought you were using $6e mask ?

Yes, thats right. I was trying to read these two chips to look at how the were done especially the one that came out of my car

 

Read as a 27c128

 

I'll try that. Thanks Tuned

 

Just tried that and same result no data. I worked nights last night...going to bed . Thanks for the help , I'll keep trying tomorrow.

 

Read the chip as a '256 and save the top half. By '89 most of the '7165 EPROMS were '256 sized as they where less expensive then the '128 chips.

I read the chip as a 27C256(read only) verifed the buffer and then saved with the same results, all data 0

 

I am using the $6E XDF file to try and view this data. Is that still correct? It is what I used to look at my AYPY bin data.

 

Correction -my APYP bin not AYPY bin

 

What part of the buffer did you save? Needs to be the top half, not the whole thing.

That is the correct xdf.

RBob.

 

I am confused what are the buffer and chip addresses needed

 

Here are the offsets for reading and programming a 16k file on a 256 prom.

 

If you have any flash proms you can do a burn then a read to see if it reads that data.
Just watch your offsets. If it won’t read what you burned I’d say the burn 1 is faulty.

I burned the APYP bin I had to a blank chip and then read the chip and saved the buffer as test1. Loaded it in tuner pro RT and it showed the data

 

Have you tried the proms in the car ? You would get a code 51 if the chips are corrupt. I can’t imagine why two chips are showing all zeros.
If the Hypertech is a 128922 I can post a copy of the .bin or email it to you.
If you want me to try a read on a burn 2 and pocket programmer just pay shipping and I’ll try to help.

 

The car has the motor out right now. I'm trying to learn Tuner Pro RT as thing progress on the new engine and transmission. I was really just reading the HyperTech chip to look at the data for infromation but the Lingenfelter ,Florida man, chip was what was running my car and I thought that it may be a better starting point than even the APYP bin that I have. If I cant figure anything out I may take you up on your offer to read it.

 

Let me know if I can assist. Hope you can get it to read though.

 

@rbob , can trying to read the 27c128 or 27c256 as a 2732 damage the prom ?

 

I have exchanged several emails with Dave Blundell from Moates Support. He seems to think the chip is damaged. Reading it as 2732A(read only) I can get a Success and a Verify Success and then save the file. I saved it as Test1 and have tried to attach it. All data was zeros when I tried to look at it in Tuner Pro RT.

 

Looks blank, I’m not sure what the voltage apply is I think it’s vcc

 

I’m not sure if the chip has a leg cut making the information encrypted.
The memcals cover is glued on with a rtv. I didn’t want to desterb it but it might still be useable. I did a read on it and came up with very little data see image. The Hypertech is odd it’s a 24 pin chip. It should be a 28 pin chip. I couldn’t pull any data from it . Wish I was more helpful. I’ll send back the chips tomorrow.

 

The memcal has some strange wires on it , I think it’s made to prevent a read.

 

Thanks for all your help Tuned. I'll keep moving forward from here, glad it just was not my mistake.

 

I think the memcal is still good I’d try it once your up and running again.

 

Good, that means I could mount it on my G1 adapter and then install my own chip and use it for limp home mode? If not I will have to aquire ...Thanks

 

You can mount it to the g1 the netress limp home and cylinder select resistors are in modified just covered in nasty rtv.

 

I recieved my chips back today Tuned. Thanks for all your help

 

Wish I was more help, maybe rbob knows how to disable the jumpers soldered in so a read can be done on the memcal. Too bad it’s all covered in rtv so you can really see what’s going on with it.
