Do you have stock excractors or aftermarket ?
i have an aftermarket extractors. and the honda accord was not modified at all!!!!!! and i still lost to it....
it really had lot more power then now....
what is happening with my fto!?!??!?!
poster - just save yourself the hassle and take it to a reputable workshop and they'll be able to check the timing for you. even if it requires a small dyno run to check everything is ok it saves a lot of time and pain. it could be something as weird as you're having a vacuum leak, or you're timing is a little off, or but it'll take you ages to find out. nobody here can actually physically see anything wrong with your car from what you've described (ie. the mods that you've done) so this would be your best bet as there's only so much that we can suggest.
if they say there's nothing wrong, well then we know it's pebcat hehe
Alright time for me to make a post =P Long read so feel free to skip if you don't care about nuts and bolts of things =)
Changing your Mivec point will not improve performance whatsoever IMHO. You'd think that Mitsubishi would have put a lot of $$$ into R&D into the best changeover point for smoothness as well as power.
Anyways, back to theory, there are two cam profiles we're dealing with, both are designed to work best at a certain RPM range.
Now changing cam profiles will take a certain amount of energy. If you change it too low, you'll spend a lot of time (and energy) swapping cams, which would in effect increase energy usage and wear. (and tell me who would stay below 3.5k rpm when accelerating =P)
Change it too high, and you'll out of the effective range of the low cam and the momentum you gain from accleration will be lost at changeover.
If changing the engagement and disengagement points does create a power increase due to a more conservative setting, you'd also have to change the fuel maps to account for this, something that most standalone mivec controllers won't do to any great degree of granularity.
On cat converters: As said earlier, These little things convert toxic emissions that occur when the fuel isn't cleanly burnt into more harmless elements. If you cleanly burn all your fuel, you generally get CO2, water and nitrogen (and a few other trace emissions)
If it isn't cleanly burnt, you get nasties like CO (carbon monoxide for you not chemical people) and NOx (nitrous oxides of various forms) and unburnt hydrocarbons (unused fuel =P)
Catalytic Converters contain elements that are catalysts for CO and NOx to convert them to water vapour and CO2 (Still a greenhouse gas but it isn't toxic) Now, you're not going to be able convert everything but it does convert a majority of these elements if you're running a lambda sensor that's working correctly and the ECU is mixing the fuel correctly.
Eric, i'm glad you back & sort things out here. So you still in W.A or back in Melb?
