hopefully that works now guys

sorry bout that!

For meth - What ever you use to switch maps on not ICS cars (if that becomes a push button switch wired into the ECU) that same input could also be used by the meth failsafe. Most failsafes can give power or ground or complete a circuit on failsafe activation.

Any Idea's other than a switch of how you might switch maps on non ICS cars?

 

Well I was going to use the A/C button - but its not momentary

A possibility is :
* Car Off
* Ign ON
* Clutch IN
* Use and HOLD TPS to select map
* Clutch Out.

However that kind of pedal dance will get frustrating!

I guess if everyone is happy to wire in a momentary button then that could be the solution! However I suspect this wont be the case, and anyways utilising stock hardware is so much nicer

If the ACD switch was wired into the ECU then that would be perfect - but I'm 95% its not

 

I will check the new ROM when I get home.

 

2 injector scalings in V5 or V6 or whenever (and if) you can get to them would be GREAT as well, Dave!

 

yeah thats the plan...

 

Well, I just took a look at the ACD wiring diagrams. The ACD switch is wired into the ACD ECU and three separate pins then control which state it is in (tarmac, gravel, snow).

However, the ACD ECU pin 36 is wired directly into the main ECU pin 79 and indirectly into pin 78. I'm no expert at reading these things, but maybe there is something that we can do with pin 79? Here are the two pages that I am referring to:

hrmm interesting - 79 might be worth looking at... let me check my disasm ..

Anyone want to open the ECU up to find out which port pin 79 is connected to?

 

Tephra, just trying to clarify a few things:

Is this only true if "Flash ICS on ALT MAP" is enabled? If not what does that do?

"Rev Limit Switching" is valet mode right?

If the ALT MAP is active and the IGN is turned off, will it always retain this value, or only if "Restore ICS State on IGN" is enabled?

All the times are in milliseconds right? A setting of 10 in "Alternate Map Time to Activate" would be equal to a 100th of a second? Meaning that a quick push of the button would be enough to switch the map? (I wouldn't do this, just wondering)

 

"Flash ICS on Altmap" does exactly that - if you are currently running your AltMap's then having this variable set to 1 flashes the ICS Lamp, 0 does not flash it.

Some ppl may find the flashing annoying! I might get rid of this option as I think you definitely need the flashing

"Rev Limit switching" should be "Enable Valet Mode"

"Restore ICS State" is independant of AltMaps, ie if you have "Restore ICS state = 0" then Altmaps will come back to whatever you left them at before.

milliseconds yes!

Also holding down the button (TPS or Auto ICS) doesn't cycle between ON and OFF anymore - you need discreet press'n'holds.

 

Awesome stuff. Any idea if you are going to move the boost control maps into being switchable as well?

 

yeah - probably V5 or V6 thou

Thanks Bryan!!

What ROMID you got - I will try and do that one next! (hopefully its got ICS??)
