Just tuned my V-AFC and here my result....







Only pushing 120 at the wheel and 109 tq i might get 142hp at engine. Run in 90.74 F, 29.72 in-Hg and Humidity is 26%

well you see there a dip on a/F chart the tunner said i might can get extra more hp if i get him more time. I only tunning for an hour so, if i get it tune for extra hour he going to charge me extra $110 plus i don't think is worth it...

Mod:
- AEM CAI
-HP header
-Apexi N1 exhaust
-V-AFC2

Man at my work today a Supra pulled 790 easily and as you all know they can do way more, but we have Civics and 120 to the wheel gets a thumbs up. Thanks for the chart.

what is that spike @ 4.3k rpms... vTEC?

vtec

yeah that's the hi cam profile engagement point.

and i don't like that big dip in your a/f. i'm curious because it looks like before tuning it wasn't there.

it looks like what happens is he doesn't have the hi/low air/fuel ratio set the same for the rpms at which the hi cam engages. in other words, let's say on the low mapping he has +5% at 4300rpm, and low>>hi (vtec) engagement is set at 4300rpm, but the high mapping is set at say +8% at 4300rpm or 4400rpm.

that's just my theory.

something is wrong with that tuning. First, you should not see a vtec spike like that. I'm guessing you changed the engagement? Well change it back to stock. Second, the a/f ratio is terrible after correction. Stock looks better. I would take it to someone that actually knows how to do it. That a/f should be linear. But even so, 120whp is very impressive.

^^ Should i change it back to stock vtec engagement or should i just leave it alone? What is the Vtec engagement point?

i would strongly suggest changing the vtec back to stock which is four stars **** since the ecu engages vtec differently based on a wide variety of conditions.

stock hi cam engagement point IS 4300rpm. so no, they didn't move it.

but i agree. take it someplace else. these guys don't know what they're doing...

^^I'm going to take it to someone else whenever i have extra money. It going be a while ,so it is good to drive it for now?

120WHP is pretty good for a D17A2 for the mods that you have! I would think thats what the average healthy D16-D17 would get.

I'm curious to see if you ever dyno again soon ...

take off your power steering belt (not for good ... just for the dyno) and also do the throttle body coolant bypass
