Automatic switch or not there should be an option to switch manually. This is what setzi62 wrote about writing to EEPROM
"The EEPROM is connected to the CPU via an SPI bus, it is the SSC in the C167.
Look for SSCCON in the code."

Yes, that is true. But if you want to do it right, you would write it to the EEPROM IMO.
Because otherwise good luck starting the car on E85 on a cold day if for some reason you had to disconnect the battery or remove the ECU.
Makes sense. I would also suggest having a way to manually override as a backup too. Back to detection... How can we differentiate between a faulty MAF and E85? Fuel trims and absence of KR alone can't do that? Will LTFT learn fast enough to make the switch before any damage is done? %STADAP might be useful. |

I'll maintain a flow diag and an outline in OP that we can refer to. Specifically the outline to know what aspect is currently being discussed.

Btw elRey, are you aware that in winter more gasoline is blended into the E85 mix and in summer less gasoline?
Binary solutions don't work very well for E85 fueling... It is not the end of the world of course, but doing it right would involve a progressive system.

I'm aware. But look at our current situation. All way have now is a binary solution via full flash, unisettings, or manual switch. This it just one step further. Are there more steps to beyond this, yes. But I want to concentrate on this one step. Once it's done, we can (and will) build from there. And rey is fine  What about already set condition that we might be able to leverage? i.e. I.A -> B_frmax |

Well I consider the conditions to SET the switch and conditions to RESET to be separate. Maybe use LTFT to SET but frm_w over a small amount of time to RESET? |

Will help if I provide you some ME7.5.10 files used in flex fuel cars in Brazil ? (C20/93oct to E100/110oct fuels)
I Guess I have some for EA827 2.0 8v and EA111 1.6 8v NA engines

Thank you. The file you posted seems to be ME7.9.6. I'll dive into it tonight. Were there any Turbocharged Total Flex vehicles offered in Brazil or just NA Total Flex? |

Sorry...forget to attach the ME7.5.30
Only NA engines, one friend in FIAT said that to make ME7.9.10 (Fiat Punto GT 1,4 turbo 155cv) bosch asked too much.

Are these cars equipped with a flex fuel sensor?

From the little reading I've done, no. They use a SFS (Software Fuel Sensor) using existing sensors. IE what we are trying to do.

shl r2, #2
mov r12, [r2+word_815D50]
mov r13, [r2+word_815D52]
mov r14, #211h
