Ms2 Cpu Running In Breadboard With Egt Input

[sub205 5]

Working on an integrated EGT input for my Megasquirt, today my MS2-CPU came and i'm integrating it all together ...

Nice little setup you have going there.

 

What are you using to connect to the thermocouple out of interest?

Mmmmm...

i'm using an ad595cq thermocouple interface.

got 3 samples from analog devices.

 

my new ms-board will integrate some nice features i'll show you later.

 

the cable needed to configure is just annoying ;-)

 

and yes, just a breadboard, but my ms1-specialedition is already running, but before i'll go further i want to test everything intensively.

Quite common on the continent it seems. All the continental lorry drivers seem to do it!

Still, damn funny though

 

Back on topic, some VAG cars use an EGT probe and have a suitable interface to the ECU - I know for certain that an Emerald can take an input from the VAG interface - Is your solution for elegant or cheaper than using the VAG one?

my interface costs about 20€ and can interface every k-type sensor.

 

it delivers a 0-5volt signal proportional to the temperature.

 

the most expensive part is the AD595, the rest are just small parts.

work finished, tomorrow it will be tested. dryrun worked.

 

 

ps: images slightly over 160k, sorry.

could not resist to test it ... did a quick setup at my desk, loaded the maps of my ms1 and went to the garage...

 

first check: idle stepper valve - passed! :-)

second check: ignition. ran smooth and nearly perfect - YES!

 

now its time for some whisky to celebrate ;-)

Looking good, a very sweat install, great work.

 

I did think about putting my MS into a 'ECU' box, but never got around to it. What I did do, and much happer about it was using a remote MAP sensor, so I didnt have to have that silly pipe running all the way to the ECU.

 

Note to self: Blag a couple AD595s....

 

Mad.

i'm planing to build an pcb with all that stuff on it so i dont have to use 3 pcbs. the first ecu was planned as an replacement for the stock m1.3, later i changed the engine to the xu10 with the marelli and wasted spark, so i had to improvise.

 

 

the ad595s are quite expensive... fortunately i got some samples
