holley tbi sensor

okay getting closer to the end. my question is how do i change the acs(air charge sensor) to read double the air for the dual tbi set-up. ran the IAT in the center of the two tbi's

If this is an air charge temperature sensor, then you want it to read the temperature, not double the temperature. The code will use this temperature + ReqFuel to get you approximate fueling, then you start tuning.

so i can delete the ACS if i run the LAT.What about a MAF ? OR MAS to get it closer to perfect. am running o2 sensor...

I certainly have to agree with Al. (Al, being the expert and resident guru and all that)

IMHO....... I would use IAT without the extra hardware such as MAF/MAS.

Your concern over having 2 tb's may be misplaced. As long as the IAT sensor knows what the intake temperature is, MS will make the adjustments to ReqFuel as Al pointed out. As long as the IAT is located in the intake stream it will work no matter how many tb's you are using.

what about a map daddy?

Is this a boosted application?

If it is not boosted I don't think the Map Daddy is going to help you much, unless you are looking to use the baro correction capability. I have found that the standard map sensor that comes with the MSII kit works very well in my NA installation. (for over 4 years btw)

Your question might be better answered by Matt or one of the other gurus.

No this is not a boosted app. a bbc 496 with afr 325 heads holley pro dominator intake with 2/ 700 tbi's 65lbs injectors.ignition is msd 6al /crank trigger ,single coil.

Azdude is there any way i can get pic. Im planning a project using dual tbi on a sbc. A single air intake sensor is all your gonna need just plumb it in the air intake tube.

can i put it in the throtlebody where the iac was.... it has airflow over the sensor.... i'll take pics of the tbi
i currently have the IAT in the intake....

I certainly would not try to put an IAT sensor in the place of the IAC valve! The IAC valve is there for a reason. The IAT sensor needs to be in the air intake system where it will give a realistic measure of the air temperature being supplied to both throttle bodies.

Mount the air temp sensor in the air cleaner. You will only need 1 iac motor. For the other motor that will be unused just make sure its closed and leave it unplugged.

Ill pm you my cell.
