2732 programming with TL866II+ programmer

**dave w** · 10-09-2021

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?

I'm not familiar with TL866II but to elaborate what dave w...this pic shows the EPROM orientation. Programmer has a legend on itself showing which direction the "half moon" on the EPROM suppose to be.

I've used Pocket Programmer 2 and an APU1 which the "half moon" faces the same direction but take notice of which pins are vacant in the pic below. My question to TL866II owners if this would apply to the TL866II as well???

I can read and blank check without any problem. Programming doesn´t work and it does not give any fault code or any other hints than "programming failed". The orientation should therefore be correct?
To rule out that the problem would be caused by the bin-file itself, I tried by simply reading the 2732 with the original fuel map and then write that on a blank eprom. This does not work either, hence I don't think the problem is in the file.

I can't see what it is you attached in the last post. I neglected to mention that the APU1 won't program the "UV erase" EPROMs well at least from my experience. The PPII didn't have a problem with the difference being APU1 is USB powered and PPII has an external power source. Sorta remember that 2732 needs 25v to program and 2732A needs 21v and pin voltage specifications has no bearing on programming. Boosting USB 5v to program something that requires 21-25v could be troublesome. Any reason not to delve into EEPROMs? Once you take the plunge, you'll never go back.

This gave me an idea. I have Moates socket booster (http://www.moates.net/socket-booster....html?cPath=26). Can I just ditch the old 24 pin EPROMS and instead place a 28-pin EEPROM in the socket booster and then place the socket booster in the ECM? Is there something that I need to take into account when programming?

Installation and Use
The Socket Booster has a single switch on it which controls how the device operates. The SocketBooster can either boost signals passing straight through it (28 pin setting) or act as a 24->28 pin converter (like the G2 we also sell) with the switch in the 24 pin position. Although we do NOT recommend this, you can solder a SocketBooster directly into a 24 pin ECM by trimming the two pins closest to the switch and setting the switch to the 24 pin setting.
