Yesterday I went to a Dyno and my car at 6000 RPM's started to go low on fuel. From 6000 rpms it started to go low until the AFR was at 15.1 that was at 7000 rpm's. Tha car is with AEM EMS and the injectors I'm using are 880 with 3ohm. We tested with a lot of fuel from 6000 RPM's and so on, but nothing work. Was woundering is I need a Resistor pack since the S2K work with 12ohm instead of a 3ohm. Or whatcould the problem is. Those injector are suposed to hold up to 600 HP or maybe more but is not working. Is it a MUST to buy the resistor pack for the injectors or is any other thing that could be houlding the car from going to 9000 RPM's with the Air and fuel in a perfect ratio.


THANKS IN ADVANCE!!

 

My guess is you fried the injector drivers. YOU MUST RESIST THE INJECTORS BACK UP TO 12 OHM!
Radioshack sells 10amp 10ohm resistors that you wire in-line with each injector. Pick the black/yellow wires on each injector. Shouldnt cost more than $6. In the mean time, remove the wastegate spring/SC belt and try running the car NA on the stock injectors. If the car wont run, send the box back to AEM so they can replace the injector drivers that you fried.

 

Yup, you HAVE to run a resistor pack or P&H injector driver box.
