Looking for help with prop. prepre chips to my ECU. I have MSA25.1 in my MB W210 3.0TD. Flash - both B58517 chips (on sticker 357710). I was desolder chips, solder sockets, purchased two AM29F040B-55. One file (Bosch__357710-711_3C0D.Stage1) was load to WinOLS and export to HHH LLL files with deault settings. Unfortunately engine not work :( Checksums different. Can you help me?

I didn't see your files but...B58517 EPROM is the same as 28F020 PLCC32.

Were the 29F040's came up from?

Dear dcjcode ( https://www.youtube.com/@dvjcodec ) :-) your are building pretty cool Controllers.

Iam playing with my EDC15 0281001624 and Winols. It is for my W210 OM606, iam driving with used vegetable Oil. ;-) .
Without Mappack it is very difficult, but some good results i could get.
EGR Off and remap the maps where EGR is in, driver wish.
But more Boost ( 1,5 Bar is wanted ) wouldnt work....

I found your Stage1 file here but without password.... Could i get the password?
Kind regards Thomas
