Finally got the last part in for my BBSC install and started up the car. I did this with the base calibration running with a fuel map created using a new injector size of 550 and stock size of 240. This created a -56% adjustment in the map in the idle range. I am not making any changes to the timing map. Car started but ran really poorly and my AEM wideband gauge showed an AFR of 15 to 18 but quickly pegged to 18. I did some troubleshooting and eventually found that I needed to adjust the fuel map all the way up to -30% to get it running smoothly. This makes it seem like the injectors are either not flowing as much as they should or something else going on as I would think the map created by the FIC should have been very accurate since it is based on the percent change between the injector sizes. Is this somewhat normal with the AEM FIC? I am running RC 550 injectors and I have the BBSC but not running the charge pipe into the intake at the moment so no boost just trying to get the FIC to adjust the injector duty cycle properly. I would like to try to verify I dont have a problem before heading to the tuner so any assistance would be great.
Also does anyone have the settings I should use in the settings screen such as the following: injector response time (400 is recommended but the FIC came with a tune that had 1400 in there), ignition load input (MAF, MAP, or TPS and slew rate), MAF (load input, mode, max voltage clamp)
Thanks in advance,
James
