R270 Programmer Red vs Blue PCB: R270 Blue Wins!

R270 Programmer with a RED board: NOT WORK

The r270 has red pcb does not read the m35080 eeprom from my e90 dash, i’ve also bought some new eproms but still no luck…

R270 Programmer with a BLUE board: WORKS GOOD


Using blue one adapter, very happy with it

after changing power supply no problem to erase m35080 , it read before with chinese power supply , of course 358080VP not erasable

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

3- Change resistor:

Note: rework r270 on your own risk

If you are not good at pcb rework, go to have a HQ clone confirmed working with m35080:


Tip 2: How to make R270 better on M35080:
Replace the resistor R11 by 200-1K resistor.

Note: rework r270 on your own risk

Tip 3: R270 Blue PCB works good with m35080
