so i was going to the ref to try to get bar'd, and i have an apex afc II. i reseted the settings to run on just the stock ecu. i normally had vtec kick in at 5500, and now its running at the stock 4400. i was thinking it should run fine on the stock settings, but now at 4400 is feels like it slows down a little until the secondary butterflies open at 5800.

i was wondering if anyone is just running a stock gsr ecu, and how their vtec cross over feels.

any helpful info would be appreicated.

 

mine feels fine...

 

I had the same question. I have a gsr in a eg so you would think that you could hear the crossover really loud, but at 5300 you can feel a huge difference in sound and the way the car pulls is a p28 a gsr ecu?

No, it is a P72.

 

wen u gonna get it ref, cuz i heard the vafc is not legal, they might fail u right there, and i thought the first cross over point is really weak and barely notice until it hit 5500 or watever ur car set at, then u'll feel and hear it loud

 

i'm not worried about hearing the vtec engagement. i just dont think it feels as smoth when its set at 4400 versus 5500. i hid the afc behind the din pockets in my optional audio console. so they didn't see it. just had to fix a hose, and work on my damn smog numbers though.

 

i had it at 4800. felt like ****, went to 5200 and it was much better. im currently at 5500 and plan on leaving it there until i can dyno tune

 

w/o proper tune that vafc, u wont feel good at all, i had it for like a month and i took it out and install the s100 chip instead...and oh yea, those ref really picky about every single things in the engine bay, i went there bak and forth like 4 times to get that damn sticker, how high is ur smog number???

 

i dont have anything changed right now. i initialized the vafc, so basically just running the stock ecu. when i had messed with the vtec engagement, when it was set at 5500, it felt so much smother. i'm just saying, the stock setting seems crappy. i would think, since it's stock settings, it would be fine though.


my smog numbers were really really crappy. i dont remember the exact numbers, but for 15 mph, my nox numbers were tripple the max amount. i'm going to replace the cat, o2 sensor, and change out spark plugs. hopefully that should do it. i didn't do any of that stuff, because i had that done when i swapped the motor. but that was back in march.

 

so u change those things bak in march??? it shouldnt be went bad, check ur valve train, if they got loose, those number can really ruin it, and i noe engine swap, cuz wen i swap mine, all the number was like hella low, it even below the average number.... check ur engine, that juss a thought
