+1 So I have heard from a few reliable sources.
Also heard that the nismo versions have a non-dumbing ECU.
But then again, who can prove the Zeds stock ECU does cancel out mods. Maybe this was a lie started by ECU companies.
when i reset an engine code for Throttle responce, we set up the car on the OBD II reader, with my JWT it showed throttle response at only 90%, the engine was not having to work as hard, because the JWT let more air in, it there just used less throttle.
I wonder why people are saying the ECU adapts over a week then if it showed for you instantly? With the stock air filter did it show 100% Surely if it measures the air flow then it would try to restrict FI?
(BTW I'm not arguing - just gathering info )
