Get the Hondata reflash. It will lower the vtec engagement to 4,500rpm I believe.

hmm reflash is better man.

Wrong. You can absolutely go back to stock by sending your ECU back to Hondata and paying $75 (I think it is)...

I do not believe there is any vtec controller for ivtec yet.

LOL. You've just got to love misleading information.

Long time ago, us tuners believe that vtec cross over engagement should not change from that of the oem setting, unless if you had an after market cam.

i seen a vtec controller for sale on the net, but is it out for the new Si's? dont wanna buy it for no reason?

Grizam303 · 04-20-2008, 06:07 PM

I saw the Camcon 201 for sale at a local tuner shop, they said it would work...

***thatsnotstock*** · 04-20-2008, 06:09 PM

you can control vtec crossover with aem fic but not worth it at this moment I would probably get hondata that whats I'm doing

ryanmcm83 · 04-20-2008, 09:50 PM

the 4500rpm vtec is not the same vtec as the one at 6800rpm. VTEC is variable valve timing and lift, which basically gives you more lift at 6800rpm. With the Hondata reflash, that effect is still there. What you get between 4500rpm and 6800rpm is the ivtec, which is just an adjustment to the phase of the intake cam shaft to optimize cylinder pressure at WOT. I remember reading on the Hondata forum that they simply used the Ivtec control to add 25 degrees of cam angle advancement at 4500rpm and adjusted timing to get more power. They also said they changed the vtec point but personal experience with the mod says that the same ol vtec kicks in at 6800rpm cuz u can really feel it and teh 4500rpm cam advancement adds a little power that normally would dip. Course the results are great and they know how to reprogram the stock ECU so props to them. I have the reflash still and have no complaints.

Maybe I'm looking at the wrong dyno numbers, but doesn't a reflash just increase hp/tq under 6k, and doesn't really do much past that?

What about a V-Tec controller like Apexi or something of that sort? A ton of guys used to run these back in the day. Why not now?
