Can either type of VIM be used to send data to an M800 ECU?

[Chris Wilson]

I know that the VIM modules are advertised as for feeding inputs into an ACL or dash, but can they also feed an M800 ecu if there's no logger or dash fitted? I intend, when funds allow, to buy an ACL, but need more inputs into my M800, buying a VIM now would make sense if it would feed the ecu meanwhile. Thanks.

SKMs feed knock to the ECU - rather than wired and done inside the M800
The LTC (Lambda to CAN) or something like that feeds Lambda to the M800 over CAN.
So we know at least things can get to the M800, and I think thermocouples get to the M800 via a VINM or 888. Not sure if the M800 can use EGT?? - which is a good thread drift topic.

Don't think the VIM is compatible with ECU's only 2nd and 3rd gen dashes, somebody can confirm this.

No direct input into the Mxxx for thermocouples, amplifier circuit required, such as the Analog Devices AN594 chip.

Another option is the 816/888 expander.

888 you gain 8 TC's (direct wired K type) 8 analogs, and 8 switch/PWM outputs, 4 digitals and 2 switched inputs, you lose 4 inj outputs and if you assign tables to all 8 of the 888 outputs you lose all 8 inj trim tables in the M8xx. If you only assign the 4 tables lost on the M8xx to the 888 outputs you then have 4 888 outputs with tables, and 4 with no tables. Not exactly sure how it would work on an M400.

816 has 16 AV's, two AT's, 4 digital inputs, 2 switched inputs, and 8 outputs.

All over the CAN.

VIMs are only supported currently by the ACL and ADL3.

The only other way to get more generic AV inputs into an M800 is via Motec dash, E888 or E816.

OK, thanks for that, would be nice if a VIM could also be used by an ECU, not sure if that's technically feasible of course, or if marketing strategies would make it unpalatable.

The guys are right that a VIM or SVIM are not compatible with any of our ECUs so for expanding the inputs into an ECU, the E888 or E816 are your only option.
