ECU compatibility???

[mike's machine]

Which ecu box is compatible with M-box?
I have seen a post with all the good info, I can't find it!
can someone direct me to that post, or can you tell me what else I could use?
I need new ECU and I can't find any m-box ecu here or on ebay!!!
Please help!!!

any the 02 6 speed would work. forgot the letter though.

what if I can't find any M or T box?
My car has been sitting in a shop for a couple of weeks, I really need a working ECU!!!
I was going to get a chiped ecu, but I can't find Neither!!!
I'm in big trouble...=/

I hear mthomas may have a chipped ECU for sale....

Will A-box work with M-box, 2001.5, 6-speed?

I bookmarked this 'cause I use it so much.

It will work regardless, but if it isnt the right one it will just set off your epc light which just takes a few seconds to reprogram. I have done that in the past.

Thank you so much MavSBM!!!
That's what I was looking for!!!
I'm going to bookmark that, too!
So for M-box, I can use either T(2002) or H(2001) box, but not A(2000) box?

let me know if you want mine i have a 2002 6spd and i just had to recode the cluster when I got it. I would check for you, but my car is getting its ko4's installed right now!!

i have a 2000 s4 and it had a-box before i ran stage 3. now its got M-box.. works great, after recoding cluster

[mike's machine]

So A and M are compatible???

[ThirdStrike]

So A and M are compatible???

if you put an a-box in your car your cluster will throw a cel until you recode it to match the new ecu, otherwise it would work. someone please correct me if im wrong.. but this is what i did but going from a to m not the reverse

[mike's machine]

So A to M is possible but no guarantee from M to A?
Hmm...

[The_Jerbel]

You can go either way, but you need more than a cluster recode. You also need to swap in the correct MAF sensor for whichever ECU you're using. A box requires Bosch MAF and M/T boxes require Hitachi.
