Now I just bought my tsx it's fast I just need to hit Vtec at lower rpms now my question is which Vtec controller would be best? I have an apexi v-afc2 that I ran on my DC2 would it work for my 04 6spd tsx?

 

i have a feeling the obd2 ecu is going to kick your ****. i believe it will cel into limp mode.

 

Adjusting VTEC to an earlier RPM isn't going to work too well for you without also adjusting the cam angle at the same time (VTC), and then also fuel and ignition timing. I wouldn't recommend installing a "VTEC controller"

 

what is the variation of timing, on say the k24, at vtec engagement (timing at low cam just before and timing at high cam after engagement)

 

I think vtec starts to engage at 6k but am not sure let me check today after work, thank you every
One who's responding

 

It is variable depending on engine load, etc..

 

I think the factory setting is at 7k or even 7500rpm.

 

crossover is at 6000rpm on the k24a3

 

What grade of fuel is best that I use , my brother has a 04 accord k24 5spd he uses grade 87 I have an 04 tsx k24 6spd I've been using 91 would it be ok if I down grade to 87 or are there any side effects???

 

vtec kicks at 6k. redline is at 7k, maybe 7.4k but thats CUTTING IT!

 

Just get your ecu reflashed by hondata!!! It's only $300 plus shipping. Steal and Deffinetly worth it!! Vtec's lowered to 5000rpm's and redlined at 7600rpms. Best bang for the buck. VTec controllers are for bseries.

 

Ok now I just got one more issue my " vsa /!\ " light is on I changed my brake but they still won't work and yes I naught correct light bulbs 7443, what can I do ???

 

our motor are meant for 91 or premium for whatever state you're in. lowering the octane would basically make your car weaker. I dont know if there are any harmful side effects, but i do know you wont feel as much power.

 

Na its cool ill just stick to premium thanks to all that have helped out
