alright b4 i hooked up my 2g knock sensor and wired in the speed sensor and added a 325 ohm resistor to the iat circuit the car ran pretty good couldnt rev past 4500rpm but it ran strong and fast after i added those 3 things the car wont rev past 2500 in drive if i hold it in L-2-3-d i can rev to 4500 in L 3500in 2nd, 3000rpm in 3rd and 2500 in D. it stops the car whenever it would hit good boost it wont let me spool it up and for some reason even though it shouldnt it seems to be running lean. ill post three logs 1 is b4 i installed it all 1 is with knock sensor, 1 is without knock sensor and the last is with it set to not read knock.
knock disabled

why did you need to wire in a resistor to the IAT circuit?

it was in the dual ecu tut. said hookup a resistor to a ground with a resistance of 300-350ohms to give it a normal temp reading. why does ours read properly with it?

I dont remember doing that part? which tut were you looking at?

johnathansgalant dual evo ecu setup its in his special notes it also says add one for coolant temp but i just grabbed a new evo sensor from autozone for 17 bucks.

alright so i hooked up our iat sensor and my air temp is sitting around 40-60 degrees its about that temp out today but i was checking my logs (bringing stuff up and seeing if anything spiked like my load does and my 02 sensor voltage, injector pulse width, and injector duty cycle get reeeeeally high when my load spikes now i know obviously there gonna go up if the load goes up but they are going way beyond what they should be putting out for the load its on. ex. i have an old log and at 10psi 4.5k rpm and 200 load its a little less then half the amount its putting out at 2.5k rpm and 0psi at 150 load. does anyone know what would make it ignore my map and try to enrichen like mad like that or anything that would cause the load to spike like that?
