I wouldn't mind getting rid of some popping, I know there's not a power gain or anything.
So according to the pics in that thread, in the service manual the AIS is the pipe called 'air filter case to air cut off valve hose'. It's a 2004 manual, hope it still applies.
Also in that thread I found a statement on the co setting that puts it in perspective (though others may have said the same)
Quote:
Co adjustment through the dash does effect A/F ratio & the running of the motor but only up to a TPS angle of 18, after a throttle angle of (18 TPS) the motor runs on a 3D fuel map & the Co adjustment does not effect the A/F ratio.
..and...
The Co adjustment will only work at around 2 to 5% throttle opening, after that it runs on the map. the CO can be adjusted from -10 to + 20. |
So really there's not a lot it will achieve, though better than nothing. I guess with the throttle mod that helps.
Fuel mod and new filter on the way.
And yes, it is kinda fun to tinker.
Thanks all.
