Emanage Blue on Boosted IS300

I am wondering if you could you a Greddy emanage blue on an IS300 and get by with it. I am looking to boost in the future and will be going piggyback because of budget reasons. Would an Emanage Blue work for boosting applications? I am looking to make 300-350rwhp.

I would do the newer ultimate. But yes, as long as the power gain and boost is not to high.

Is emanage ultimate able to trick the stock ecu to se another AFR then it´actually is in the exhaust pipe? So you could adjust that away from stock, without stock ECU trying to correct it back?

Sorry for a bit offtopic but it´s still kinda related

You can adjust fuel and timing. But like I said. It also depends on the power levels you are dealing with.

No, neither emanage can do this. There was an option on the Ultimate at one time, but I’ve never seen it actually used. Only pictures. It took a couple daughter boards to do it.

The AEM FIC can skew O2s, but I’ve not heard how well it works.

Skewing the o2 signals is not the only way to change AFR. Also if you are referring to blind tune where you just change AFR across the board. You can do that with a wide band feed to the Emanage. But this is not effective tuning. It is much more effective to build a map then build load maps along with any other augmentation maps.

I´m not so well educated in EFI tuning so i really dont know how useful it is to skew O2 signal to ECU, but my first thought was that maybe you would like a different AFR target then stock ECU,
Would the stock ECU try to work against the piggy back systems? Or is that a non existent problem?

It fools the ECU into thinking it is seeing the AFR it needs. So yes, you can have a different AFR.
