Pin 21 question, does grounding this switch to the MS map?

[IIRC] On the USA ECU, it comes grounded.  Cutting the wire connection switches maps. European ECU it's the opposite.


It's been awhile, I typically just get a quality harness from Boost by Smith.

Found the pin and cut the wire, even tried grounding it. Looking at bike running with Editor is there no way to see if the MS map triggers??

You could simply add 10% fuel to the idle map MS map and try it at idle, that's what i did to verify the functionality..it works.

Tried that, added 20 % or more down low and ran bike in gear on stand with no discernable change grounded and not-----

Which map and where did you add 20%?

Unless you changed it, everything below the 15.5 column is only effected by the IAP Map. So, even if you ground 21 it is just staying in the IAP Map.

Just as a follow-up.


Had a nitrous bike come into the shop that had a bad PC ignition module, coils had be wired up wrong by another shop and burned up the module.  I decided to put in a relay that trigger off of the nitrous controller activation output.  When the signal is applied, the relay trips sending a ground to ECU pin 21. Works like a charm.  No ground, MS map.  Add a ground,  TPS map.

I'm confused with that-- nitrous controller sends signal to relay to ground 21--0 that should be to activate the MS for nitrous map, correct??

After the delay time, the nitrous controller sends out a 12v signal.  I wired in a 12V relay that when it triggered would send out a ground signal.  I cut the black/brown trace wire (pin 21) and wired it to the relay. So without nitrous it runs on the MS map.  After 1.5 second delay, the controller trips the relay and the ground signal causes the ECU to switch to the TPS map.  Yes, that is typically backwards, but I was just figuring it out at the time.  I may switch it around this week so that the relay cuts the ground.
