my fuel economy very bad

standalone is it

this is not a light mod to use shortcuts with - this is a serious change to the car that takes a lot of effort to get working right.

 

by bad what do you mean? If you drive light is ur fuel economy decent? or do you guzzel gas just idling lol?

... obviously its a serious change to your car but what needs to be done with the EMS that the emanage cannot do?

 

the reason why EMS is used is because with ITB;s you eliminate some of the stock sensors that make the engine run smoothly, Emanage is just a piggy back that uses the stock ECU. if the stock ECU senses that sensors are missing, it will not run, or run VERY poorly.

 

More info on the Hybusa ITB's? was size are they? MM

 

yup, more gas used idling and deccelerating too.

 

I think with the setup that I'm running, using an Emanage may be possible. It uses all the sensors except the TPS. I think it would work under two conditions:

1. Emanage lets you calibrate the TPS
2. The ecu won't throw a code since the ACV is no longer there

 

The throttle bodies are tapered so the portion connected to the bellmouth is ~50mm. Where the throttle plate is, I believe the diameter is about ~46-48mm.

 

if the IACV is missing or un plugged the stock ECU will throw a code. and Idle like hell.

 

Nono

I'm talking about the ACV (Air control valve) located on the intake near the coolant port. It's the pump which sends air into the exhaust ports to heat up the cat converter during startup.

The itb setup I'm using actually does use the IACV (Idle air control valve).

 

OK got ya, I thought you were talking about the Idle control, which in most set-ups will be eliminated, Aps2 asked why the emanage can not be used.
