from my understanding, vtec on a gsr hits a 4400 rpm and iab open up at 5800 rpm. then i heard the opposite, iabs open up at 4400 and vtec hits at 5800. can someone please clear this up?

 

vtec engages at 4400rpm and the iab i think open at 5795rpm i think im not sure but its not a completely even number in the hundreds. The reason you friend or whoever thinks that vtec hits later is because you don't feel any pull untill the iab's open. That mad Vtec yo

thats what i thought. yeah there is no complete number. i was just rounding off the numbers. also i bought a chipped ecu and i don't feel vtec kicking in around the setting that its suppost to be like arond 45 i believe. i do feel something around 58 tho. so i'm thinking that i have a sohc vtec ecu. i don't throw any codes tho.

 

The pull is more noticeable when the iab opens up. You don't really feel the pull when vtec kicks in.

You can tell what type of ecu you have by looking at the serial number.

 

4400 vtec, 5750 iab (according to helms)....

with R cams, it feels good at 5000 vtec, 5600 iab.


idle... brrrrrrr.... pop.... breeeeee.... click.... BWAAAHHHHHHHH.... 8500rpms... Slam... squee.e.e.l... -&gt;

right now i have the stock p72 obd 1. on the chipped ecu there is not serial number because they take it off when they chipped it. i tried to figure out what ecu it was.

 

while crusing in 2nd gear, slowly accelerate to 4400rpms and you will feel/hear vtec, its subtle, but its there at 4400.

 

you thinc on a bolt on gsr its any good to lower the iabs or vtec points?
