2732 programming with TL866II+ programmer

[Muhve]

I have successfully created a good fuel map with my Ostrich 2.0 for my old Saab 900 that has Bosch LH2.2 EFI. Now, my next step is to program this data to an eeprom.


This is my first ever attempt to try and program an eprom. The original eprom is an Intel 2732, however I have a blank NSC27C32Q-45 eprom that I would like to program instead.


I have a TL866II+ programmer with it’s original software. My NSC27C32Q-45 eprom can be found in the lists of different ICs and I picked it and did a blank check and pin check, all good! However, When I try to program, it just says ”programming failed”.


Found some threads here mentioning something about offsets etc, yet none of the tricks mentioned seemed to work for me. Is there someone here who could help me? Given that you have read this far, it has probably dawned on you that I am not yet so familiar with programming, but you have to start somewhere I guess

Gonna share my experience...the EPROMs that have the little window that require good ole Hawaiian sunshine or a UV eraser to blank them, my APU1 will not program them, however my Pocket Programmer doesn't have a problem with it. I've given up on those older EPROMs and recently only use the EEPROMs. Problem is unobtainable in a 24 pin which is a small problem. http://gearhead-efi.com/Fuel-Injecti...sion-(27SF512)

2732 chips have many variants, but all variants are 4K memory. 2732 chips are not unique, rare or outrageously priced. Possibly source an alternative 2732 chip that the TL866II programmer is happy with?

Thank you for your reply. I have ordered a new eprom. I uploaded my bin file here, I am not that familiar with coding, thought that someone who does might be able to tell if there is something wrong on the bin itself...

Allright now I have tried with two new 2732A eproms, Intel D2732A and AMD2732A. The AMD2732A should be 12,5V programming, but same problem still remains with both of them. What am I doing wrong here? How do I know if my laptop/docking stations USB-port provides enough current? Could this be a problem?

Are the chips correctly orientated into the programmer?

Are the chips fully erased?

Are you able to successfully program any other type of chip?

I'm thinking the programmer would likely provide an error code when it fails to program a chip?

Google drive does not like my winXP lappy, post the 4k 2732 file here, I would like to figure out the checksum. It's not your issue but I am curious.
