apexi power fc

[xero1]

anyone got a apexi power fc on their sr20det? how hard is it to tune? can the apexi power fc work with stock injectors?

I have it. Its not easy at first but once you read the manuals you understand it. Its hard to tune with the commander but can be done. We own the Power FC Pro Software so we just tune on the laptop. Also it will work with almost any injector factory or upgraded.

dont they recommend getting the first tune done at a shop? I think i remember that, it was because it is supposed to have something that has to be setup or it could cause some problems that will not go away. Its been a while. someone with one can chime in.

as long as you have a good tuning setup, self-tuning with the power fc shouldn't be a problem. you will need: a wideband o2 sensor with a logger output (such as the AEM UEGO), a laptop, the fc datalogit hardware and software, and half a brain. also i would highly recommend a g-tech pro if you want to remain completely independent of the local tuner shop and $45/run dynos. to tune, you basically log a 3rd gear run (4th if possible) with the stock fc tune (and stock boost). then, take a look at the logging results. first, correct your a/f ratio by adjusting the injector loads (if you ran lean in a certain area of the map, then increase the injector loads a bit, if rich, then decrease injector loads in that area). then, once you have a nice flat a/f curve of around 11.6-11.8 at full throttle and full boost (12-13 at spool up), you can move on to the ignition timing maps. be very careful with this one and adjust in very small amounts. the most practical approach to the most power is to keep incrementally advancing the timing until you start to see signs of knock on the logging outputs, then pull back a few degrees.so far this entire explanation has assumed that you are using stock boost settings. if you have an aftermarket boost controller (if you are using a pfc, then i would STRONGLY recommend the add-on boost control kit b/c you will be able to use the datalogit software to manipulate and log boost; plus, it's cheaper) then you should tune this AFTER the a/f tuning and BEFORE the ignition timing adjustments. be sure to check for knock after increasing boost, and retard the timing as needed.

this is a GREAT write-up on how to tune with the pfc - http://newcelica.org/forums/sh...91180

once you have the power fc, you don't need the stock ecu anymore right?
