Increase number of input channels 4x lambda reading

[chris1311]

I'm running out of free input channels for logging temp's, pressures and so on with the m800. Now I've the option to use an ADL8 (I already got one, but it's not used actually in the application). The problem is the support of (in summ) 4 wide band lambda's and the transfer of all the channels into i2-file, I think. Another chance would be to use an m600 (its also in the shelf). Is a 2x m600 / m800 bundle the way? How i can manage that the reading of both m's can be evaluated in one i2 data file?
I'm not sure if my question is in the right topic, but I'm new and it's hard to find the right one for the tricky question...
Can somebody help?

Thanks

E888 expander? Especially if your temp inputs are thermocouples, and you need a few more AV inputs. Plus you can migrate 8 of the on/off type outputs to the E888. Not saying you can't PWM an output on the E888 but you lose either 4 or 8 of the main ECU inj trim tables if you do.

I thought already about a E888 or E816 but you forget the 4 lambda requirement! My m800 has dual lambda open - so with a E888 there are still 2 lambda are missing....

You could use a LTCD to add two extra lambda sensors directly to the m800 without any extra boxes.
Or per Scotts suggestion if you also need extra analog inputs as well then use a E888 and 3rd party analog lambda controllers.

Thats right. But I thought may there is a way to use parts in the shelf.
For me the most important question is if it's possible to use 2 ecu's (master and slave) and can I use i2 like there is just one ecu.... That would sort my problems straight away.

Motec have a PDF on master slave ecu function
I did do it many years ago and it worked great
Not sure on what functions the extra lambdas will control ..think they are ecu specific
