speed density

Speed-Density systems are very sensitive to temperature changes. As such, it is critical to pay close attention to temperature correction factors. This is due to changes in air density at differing ambient air temperatures
with that being said, it would be very hard to mass produce a SD car that is sold in lost of different regions. basically a car sold in maine would theoretically require a different tune then a car sold in california. that would cost a lot of money to develop all those fuel maps. that why they use MAF because it can compensate for a lot more then speed density. when mitsubishi makes these cars, they obviously arent looking to make the most power possible. they are worried about the dollar bill

yes you shold have no problems with the aem map sensor... the reson why people use the Omni is because it has the same scailing as the standard map sensor...

Hello all, I'm actually thinking about going Speed Density as well. I will be running a VTA BOV and I'd like a good idle. I just ordered an omni power 4 bar map sensor, is there anything else I'll need in order to go speed density?

You DO NOT need an IAT if you plan on setting up SD yourself. Its a good thing to have if you want your tune to change with the air temp but if you like me ( I do all my own tuning) then you can look over tune and just keep check on it through the months when the weather change. Im not 100% sure you need it still if you live in an area where the weather might stay pretty consitant. dont quote me 100% on none of this but I know I dont run an IAT and my car runs AMAZING on SD.
