i need to study to get money and be like you when i grow up!

Originally we had a Walbro in-tank 255lph fuel pump using the stock lines to the rail and added an Aeromotive 1:1 pressure regulator to the stock fuel rail and also added a -6 fuel line to the tank to be used as a return line. We had 750cc Siemens Deka low impedance injectors with in-line resistors so the E-manage can work correctly.

Now we are going to install a second Walbro 255lph in-tank: so we are going to have twin Walbro's in the tank with a new -8 line going from the Fuel tank to the fuel rail and using the same -6 line as a return. We switched to a custom Fuel rail and kept the same Aeromotive regulator directly attached to the rail.

At that time we are going to test the setup as indicated and see what numbers we can achieve with the 750cc injectors. Normally I would install bigger injectors but since we are still running the E-manage I am reluctant to go bigger because it will be very difficult for the piggy back to run correctly at part throttle and the fuel consumption will be horrible!!

I'm sorry i never knew about in-line resistors so the emanage can work correctly... can you shine some light on that for me? I was reading on another forum for other cars like The RSX and they are raising there idle to 1000rpms and running 850cc's on a piggy back would that work for our car?

Mecanica_Pito

It can only work with high impedance injectors. Greddy, Turbonetics, Dezod and others include with their kits high impedance injectors so that it is plug & play. We bought our low impedance injectors like new very cheap but it required adding the resistors.

Correct me if I am wrong but I think RSX 's are not DBW (drive by wire) so they can rise the idle rpm's. On the tC it is not possible to do so.
It might work, might not: the question is if it will run good in every day driving and if the fuel consumption will be tolerable.

oh I forgot the RSX was DBW sorry for the question and thank you for the quick answer...

^ do you mean not dbw?

318_tC

i know a way to raise idle on DBW....

^ for some reason I really thought it could be done by the AEM management

mikescion

see there we go holding back on info like its a treasure LOL how ___....hmmm

Keeshwah

pardon my ignorance, but why would u want to raise the idle?

mikescion

to be a maybe bandaid for big injectors with piggy back for better idle and AFR's

Some people like to raise it a tad so when they shift out of gear when stopping it doesnt dip below where it should be for that second .....and stall out.

mikescion

so how can we raise the idle anyone know???????

Mecanica_Pito

He really isn't holding info on anything. I know how to do it with the AEM (like 318-tC) but I don't know how the OEM ecu will react when rising the idle. I might try it later but it is not very high on the "TO DO LIST".

^ yea the only reason why I could see ...like i said before .... is cause if you are high in the RPM's and you take it out of gear it slams below 1k and then bounces up 200rpm ..... I could see benefit if you changed it a veryyyy veryyy small amount (like 100rpm - if that is even possible I am not sure).

318_tC

Actually it's something different other than just on the AEM, something we figured out when we were at the shop tuning it originally. Notice, Dezod sell's it with there AEM unit now. It's made by T1
