Ok, I have a 99 tl I/H/E. Here is my question. The Vtec selenoid has a clip with wires running to it, obviously to make it work. Now, When I unclip it I notice no difference, my car runs the same. Now with it on or off it hits its power band at 3700 rpms, is that my cam or vtec. I cant imagine my vtec coming on that early, usually vtec on most cars turns on at like 5000 rpms. So is my vtec not working, or is it just not noticable because like I said with the vtec selenoid wires unplugged my car ran the same (I even timed it 0-60 both ways and they were the same). I am unplugging the vtec selenoid its on the driver side of the motor kinda up front.

 

On the '99 TL the VTEC kicks in at 3800RPM's, I believe, could be wrong however.

 

3800 is correct. OP what are you trying to accomplish?

 

By unplugging the Vtec selenoid shouldnt it NOT work. Im trying to see if my Vtec is working.

 

I thought I read somewhere that it was higher on the 99-01 for some reason, but I could be wrong. Did you search and find anything?

 

yea, the j32a2 vtec kicks in at approx 5k RPM, whereas the j32a1 kicks in at like 3800 or so, as previously mentioned

 

Why would you unclip it in the first place? You just curious?

 

Wrong! Its not all J32A1. The 99 kicks in much sooner than the 00-03

 

2ndgentl, if you wanna see if you Vtec is working or not, step on it and since you have a 99 you should hear the engine sound more aggressively around 4k RPM.

 

Thanks for all your help, it does work at 3700 rpms, I just had in mind that usually they work at 5000 rpms or higher, but it is lower on a 99 tl, the lower the better I think anyways.

 

Not necessarily. Do that to a 00+ and you lose power. Its all in the tunning and cams.

 

Yes, but in the 4spd you don't.

 

Dropping it much below what the factory has it at you do. My comment was to his the lower the better. People need to under stand what VTEC is and how it works. Its not some miracle mod that you can just turn on and bam there is more power

 

my Vtec kicks in at EXACTLY 3500. i hear it. i feel it. and so does everyone else. Has anyone tried making it lower or higher on the 99's? im sure there has to be some leway

 

Yes, but did you read, it doenst help moving it around much. Its tuned for where its at. Its not like bolt on mod that "just" adds horse

 

If anyone is interested in changing the Vtec engagement point get a AFc Neo and you can change it up or down and see what works best and at what rpm engagement point you get the most power. I'm sure there are plenty of people on here that have done that. AFC NEO will be my next engine mod.

 

And those who have them got gains not from changing the VTEC engagement point but actual optimizing of other things.

 

wow i get VTEC at 3800? my god...felt like 5k

 

Mine kicks in at 5k.

but its a sweet, sweet sound =]
