Throttle control table

Post by CivicVTi »

I believe there are some hidden maps in Honda' original logic control. I have made a table relatively insensitive due to having a roots supercharger and I want the car to be more driveable around town without surges of power and without actually 'using' the supercharger (M62 bypass valve closes around 85kpa and I try to be below that as it also helps fuel economy a lot). To accomplish this, I have found that a 50% throttle pedal should be about half (25%) throttle map to give you an indication of how my map is setup. Although this works very nice at low rpm (<3200), at mid to high rpm it does not work and especially when vtec is engaged, the ECU goes back to an almost 1:1 relation, especially at higher gears. As a result, even the slightest throttle use automatically closes the M62 bypass and boost is generated. Hondata, any opinions on this?

You can't change the throttle pedal to plate relationship too much otherwise the ECU thinks there is a problem and runs a default algorithm (not a table).

How much is too much?

I guess this table (attached) is out of the question :)
