To start off, this is for a MY01 with the inlinepro turbo kit with the GT35R turbo.

I am deciding between which engine management system to use, Emanage Ultimate, AEM F/IC, and Kpro.

I need to do inspection every 2 years, so standalone is not suitable for me. kpro will obviously be the best option but it will also be the most expensive. I have both the E-manage ultimate and AEM F/IC from my previous car so I would like to use them if they are capable. My power goal is in the range of 450whp.

I know both EMU and AEM F/IC can support bigger injectors, add/subtract fuel, and adjust timing. The main difference between the two is that the EMU can advance timing while the AEM F/IC cannot. However the AEM F/IC has the ability to tune within the close-loop map and the EMU cannot.

Now the question, is the ability to advance timing more important or the ability to tune within the close-loop map more useful?

Close-loop / Open-loop question:
My last car has a roots type supercharger and boost build up very quickly within the close-loop map. Since the ECU always try to adjust the AF to 14.7, this became a problem when the ECU adjust the AF to 14.7 while the supercharger is boosting. With the AEM F/IC, I was able to make the car runing richer then 14.7 within close-loop mode. This also allowed a very smooth transition between close and open loop mode.

Now the question, will I have the same problem with my turbo setup? The turbo would build boost much later as compared with a roots type supercharger. Would there be times when the turbo is building boost while the ECU is in close-loop mode and cause the engine to run very lean?


Timing advance question:
The EMU has the ability to advance timing while the AEM F/IC doesn't. Will I need to advance timing with the turbo? Timing will be retarded under boost, but will timing in the lower RPM (0-3.5k) with no boost need to be advanced in order to get better throttle response, especially with the 3mm head gasket?

VTEC engagement:
For guys with the GT35R turbo and inlinepro manifold, at what RPM do you guys adjust your VTEC engagement to?

Sorry for having so many questions, hope you guys could help me out!
Thanks!

 

Open Loop / Closed Loop Question - You will have the same problem with the units fighting eachother. Stand alone is the way to go. KPRO accomplishes this, and still retains ODBII functionality.

Timing - Yes, you would probably advance timing on a lower compression engine, so FIC will probably not be the best option.

VTEC engagement - Depends on the manifold spool characteristics.

Can I wire the Emanage ultimate and AEM F/IC together so I could use the AEM F/IC to tune the fuel in open and close loop and use the E-manage ultimate to advance and retard timing?

I know it sounds stupid, but I have both unit sitting right infront of me right now. So if there's a way to make it work, I would rather do that then selling it and buying the K-pro.

 

The emu does both.

 

Yes the EMU can do both, but the AEM F/IC has much better partial throttle fuel tuning then the EMU.

While the EMU will fight against the stock ECU in partial throttle (closed-loop) mode, the AEM F/IC on the other hand has the O2 skew feature which allows you to adjust fuel within the partial throttle (closed-loop) mode.

Stock ECU keep the AF around 14.7. With the AEM F/IC you could make the stock ECU keep the AF at any number as you wish (from 11 to 17) and the stock ECU will still be happy and not fight against it. This will eliminate the partial throttle issue as I could add fuel while in partial throttle and partial boost without the ECU fighting against it.
