R270 new software 1.20

[teerak2uk]

Hello, I played a few hours with my R270, and I succeed to make it erase 35080V6/VP in a few minutes.
First I changed 7805 with L7805CV, before voltage was 4.94V, after that is 5.02V, but nothing happends, still can't erase more than hour.
after that I start to play with 35080 PCB, and in the end started to erase 35080V6/VP after 74HC125 changed with 74HCT125M, erase 5-10min tryed on 3 chips, maybe if I change 74HC00 will be better, but I havn't one for try.

Compare with mine that works well and also has the coil many seem to be missing (unsure of pt#)

My first R270 was with coil but atmega died, I byed new one and it's without coil, but I can't see any difference, old one also didn't erease 35080V6

What is the Idea with that coil with transponder?

What about resistor change on adaptor

I have two boards, they are with right resistors, I tryed to do some changes but notting happend, but after change 74HCT125M on one of boards it start to erase it more faster...

Sometimes Chinese use correct chips but of poor quality so best to buy chips from reputable suppliers rs, mouser etc

Hello colleagues, good day. One question, I have a r270 +, my problem is that it reads the 35080vp chip but it can not erase it, it gives me error. Has it solved this problem ?, Thank you very much.

[teerak2uk]

Sometimes vp don't erase just replace the chip

[gonzcaal]

Thanks for your answer, because another chip can replace

M35080 V/VP not read/erase
1.Change the power supply to good quality: 12V 1.5A !
2:Change capacitor :

3.change resistor:
