Adaptronic 440 vs 420 & o2 input question.

440 vs 420 & o2 input question.
What are the major differences between the 440 and 420?
Does the 420 have the adaptive tuning?
This ECU option is looking really good when I compare it to my Microtech, this offer's far superior protection and functionality.
As far as the o2 input is concerned, if I'm using a wideband 0-5v input will the ECU adapt if there is a sudden change in the AFR detected?
This interests me a lot, if for example the car is tuned with the aux methanol injection running and at some point a problem arises with the methanol delivery, will the ECU detect the change and adapt to protect against detonation because of leaning out?
Or will will I only be able to protect against detonation by retarding the timing when knock occurs through the ECU?

Hi guys, yes the only difference between the two with respect to the tuning is that the 420 doesn't do adaptive tuning, that is, it doesn't adjust the fuel map.
It can still do closed loop fuel trim based on narrowband or wideband O2 sensor.
Otherwise they're the same on the tuning side of things (the 420 has fewer inputs; 4 digital in instead of 8, 1 road speed instead of 4, and no flex fuel function).
Thanks!

Gareth,
That will be a firmware update, available to all ecus, not just units produced after its available. If you've got money burning a hole in your pocket I would suggest switching to a set of ID injectors, so you have accurate dead lag settings for the ECU.

I've got a set of 850 primaries and 1680 secondaries that i intend to use. What would be the advantage of running the ID's as opposed to my setup? Is it just the ability to change the dead lag?

Andy, you mentioned that on your FD you are running the stock primaries and ID2000's as the secondaries with no noticeable transition, is this because of the ability to change the dead lag and the way the ID injectors react?

The suggestion to change injectors isn't based on your current sizes, but your current technology & published dead lag settings. The 1680cc units are not very linear in flow at low injection on time. This is part of the reason most people have a hard time tuning them. Furthermore if the dead lag settings aren't available you're just guessing at what info you give the ECU( which it needs to make proper adjustments!)

Gareth,
I have an rx8 customer running a plug in who has had some sucess with a tuning shop. I cannot remember the name, but I will get it and put you in contact if you like.
Rotaryweapon: You can still use e85 with the 420, you just can't have it self tune for the alcohol content.
