Now somebody please correct me if I am wrong...but the iVTEC in the TSX works a little different than VTEC. In my G2 93 GS-R, the VTEC kicked in from 5900rpm to 7900rpm. From what I have been told, iVTEC kicks in when ever you punch it no matter what rpm you are at. I don't know if it still kicks in for a 2000rpm span, or if it is continuous, but I am sure someone will explain in further detail.DIGGZ said:Anybody know when the vtec kicks in on TSX?
I really thought the same thing because that sounds more like how VTEC works. So what is the difference between VTEC and iVTEC? Confused as well!spyguy said:so i'm confused. i was under the impression that the iVtec was more than just an on/off of the valves opening more. i thought ivtec changes when it comes on/off depending on the driving style.
Smack whoever told you that, because it isnt true at all.caz1604 said:From what I have been told, iVTEC kicks in when ever you punch it no matter what rpm you are at. I don't know if it still kicks in for a 2000rpm span, or if it is continuous, but I am sure someone will explain in further detail.
iVtec adds variable timing. Thats it. Vtec still works the same as always...caz1604 said:I really thought the same thing because that sounds more like how VTEC works. So what is the difference between VTEC and iVTEC? Confused as well!
A salesman told me that a while back when I originally test drove the car...I guess I should have followed up to confirm.joerockt said:Smack whoever told you that, because it isnt true at all.
vtec kicks in at 6K to redline.
Great article...thnxjoerockt said:iVtec adds variable timing. Thats it. Vtec still works the same as always...
Here's a good read about ivtec http://www.honda.co.nz/site/technology/ivtec.html
<-- Is with you Noel :nod:Noel said:If I'm the only one, but I preferred the lumpy switch over which also attracted me to buying a CL9 instead of EP3 or DC5. Then again, I'm still a firm believer of the old school DOHC VTEC system over the i-DOHC VTEC system.
is the reflash available for the tsx? i just checked the website and it says that a reflash is coming, but no date of release.jprovostla said:I wish that Honda had programmed the VTEC to come on around 4000-4500RPM...
At 6000RPM it is almost useless, because the 5AT full-throttle shift point is 7000RPM...
With the Hondata reflash it's an improvement but I still wish it would engage sooner...
It is available for 2004 models. I don't know when it will be ready for 2005 models.sequoia said:is the reflash available for the tsx? i just checked the website and it says that a reflash is coming, but no date of release.
I have a friend who did this to his car, and the VTEC kicks in at 3000 RPM. the car performance is amazing compare the original settingNoel said:VTEC works best and optimally at it's factory set point, unless a lowered VTEC engagement point is tuned in accordance with the required air/fuel mix ratio and pressure to gain it's optimal setting, it is pointless. Even though so, the theory of lowering VTEC engagement to see true performanace will only work within 1000 -1500 RPM of the original setting.
