I'm trying to tune my V-AFC on my GSR with OBD-II. I had someone help me out when I first installed it. Here are my settings:
VTEC xover:

L-H: 5300
H-L: 4900

Fuel curve is gradually dumping about 11% more fuel at vtec. Fuel curve looks more like a bell curve.

Mods:

Intake, Exhaust.....


Am I running too rich here? I heard that Type-Rs run really rich from the factory, is that true for GSR's too? The car feels real good and pulls a bit harder, but after reading a couple of posts on the Type R forum, it seems that the R guys are leaning out across the aboard with the V-AFC. Can someone with the same type of set up offer some advice? I don't wanna be running to rich.


Thanks!!!

 

Tune it on a dyno.

 

With the stock cams, those settings are too high. The stock x-over should be at 4400rpm, not 5300. You won't gain anything by having it come on so late. And yes, the car runs rich from the factory.

With just the usual mods the VAFC is best left at stock settings until you get bigger cams, IMO. Save up for those cams!
