ok, all tonight, i was driving along with my friend and my car felt sluggish--when i was fllooring it...

i punched second n third, and it did indeed feel weak.
my boy was like, whoa, ur VAFC it topping out @ 85%-----
so we do some more tests, and the highest i can get is 85 percent.

i have the skunk2 itm and the itr throttle body cable---i checked that and they both seemed to be ok...

i put the key in the ignition, two clicks forward to turn on the vafc, and i floor it...
i can get 100%...

but when the engine is on, i can only top out @ 85%...

any ideas?

---if the hondatechers cant help me, hopefully the doods at the htech meet today can check it out

 

shoot ur timing...

 

I believe its your TPS sensor. See if you can find a spare one, and swap it in.

 

timing is good,
what is the tps sensor?

 

check the voltage with the car off but on the on position.
no throttle and at wot

no throttle=.45V
WOT=4.5V

Since you have an VAFC you can do the readings from that. Make sure that the voltage doesnt stumble as you slowly go WOT

 

how do i bring up the voltage screen/display??
where do i go?

btw, thanks for all the help man

 

If I remember its under the throttle guages or vafc setup. Refer to your owners manual.

 

its under the 3. option-then its under sensor display

 

I had the exact same problem as you earlier. But mine would still display 85% when the engine was off. I don't know if this will help your problem, but tighten your throttle cable. It worked for me.

 

This was the best mod I did for 1 minute of my time
