2.0 with a tec gt stand alone

What set up do you have?

honestly its not for a honda its for a 2.0 alfa romeo but i figured you guys would be the ones to ask.

a guy brought it to the shop and i was the one doomed with the project lol

like i said its got a stand alone setup and the wiring mess to go with it
the wiring wont be a problem but i was needing to know about the intake air temp sensor and what i should do about it ill see about taking some pics for you guys its got a ported head and headers for me to install on it

Ok some setups like my Twm have spots on one of the outside runners for the iats that has to be drilled and tapped ive also heard of people just mounting it outside if the intake on a fabricated plate close to the intake somit gets reading there. Then there are also people that dont even use one and just use the map and tps. Idk much about an alfa Romeo so idk if that'd work or if the tuning software would allow that

thx for the help man
it has a stand alone ecu like a mega squirt setup or aem ems
and i had seen some people just eliminate the iat sensor so thats why i was asking
is there any thing else special i should know about this whole itb setup it seems pretty self explanitory other than that damn sensor

pretty simple just a bitch to tune. youll probably need to make some kind of vaccum block setup for the map sensor to be in

Read up on Alpha-N or Alpha-N hybrid mapping. If you don't know, I would farm that area to someone that does. Someone else's car is not the car to "learn" how to tune ITB's....

yeah i heard its a b*tch to get them to idle right but the tune is part of the job so i gota figure it out one way or another ill probly keep it conservitive till i get everything else down pat. i got access to a dynojet dyno so all of that is taken care of. like i said tho any links you could send me or any tips would be awesome

btw thx for the help guys

yeah i already assumed that i got a vaccum "plenum" i guesse you could say so it would have enough available air space to pull vaccum without sending pulses to the map sensor its not too big but big enough about the size of a 20oz bottle

i read the alpha-n and thats why i was going to use the vaccum block to get a good consistant vaccum point but i do understand mid throttle will be difficult to tune for drivability. so in doing all of this assuming i cant get good drivability out of it should i set the car up to run in closed loop or should i set the alowed variation rather low so the car will run in open loop in idle and closed at for say 20%-25% throttle?
