Reading different m35080 chips

[astra1.7]

Hi guys

I've finally got round to buying a cheap upa USB programmer and Richard's decoder software. I've been having a play tonight with a couple of IPC's. The first one read fine after a few attempts which was a bog standard 1.8 astra ipc. The second one I'm having trouble with, which is a keyless vxr ipc. I can get some bits of coding, but not enough to pull the security codes. Is the chip damaged or do you think I could salvage it if I desoldered it? Or any other ideas?

Are you reading them "in circuit"?
Best practice is to desolder them from the board.
MCUs and crystals can interfere with the readout

Yes I am reading in circuit. Not the end of the world if not as I have the whole ECU kit I can read the codes from

I've always found instruments spit our garage, you could try lowering your reading voltage to stop other components becoming active
