Aem v1 and rc 550 injectors,

[Quazaky]

Im going to go get my car tuned next week i have lex afm rc550s and a aem v1 ecu, the rc550 are low impedence injectors and my research is showing me that i need to trick the aem ecu to think they are high impedance by adding resistors? CAN ANYONE shed some light on this? part numbers, locations, links everything helps want this to go/work smooth as possible. thanks

7m has a injector resistor box already wired in essentially making the low imp injectors high imp. So your fine as long as that's not bypassed.

A v1 is pretty old school as well.

 

[Quazaky]

got the v1 for a good price, so i wont need to wire in any other resistors? I haven't removed the stock one if there is one.

The resistors aren't there to trick anything in the computer, it exists to protect the drivers within the ECU. Make absolutely certain that there is a resistor in-line with the injectors or you will destroy your AEM and be very sad.

 

[Quazaky]

is the stock injector resistor good enough?

 

[toyotanos]

Yup, even if you rewire the harness for sequential injection. Been there, done that!

I'm assuming you used two resistor blocks to go sequential?

 

[hvyman]

Nope. The resistor goes on the power side.

Sequential only requires changing the grounds. Which is basically 3 wires.
