Ok...you guys are missing something very crucial. VTEC only kicks in AT HIGH THROTTLE POSITION! You WILL NOT be in VTEC at 7000rpm if you are only at 40% throttle. VTEC is based on RPM, Oil Pressure, Coolant temp and THROTTLE POSITION.

I personally have my VTEC down to 5400 with an AEM EMS on an AP1 which works out quite well and flattens the curve.

This reflash will not effect engine reliabilty. Unless of course you like it so much you are VTECing and hitting 8k everywhere you go

You, my friend, have an incorrect understanding. With the Hondata reflash, under "normal" throttle VTEC engages at 6K rpms. However, VTEC will engage at 4200 if you are at WOT. This is a "VTEC window" that Hondata has implemented with the reflash. Ask me how I know.

Header, and Gears would be ideal because you will scream up the RPM very fast with a 4.57. The hondata gives you that massive torque down low thats all it's good for. You don't gain any HP it only generates torque @ 4K. with the Gears you would rev up to your V-tec Range quick. Not to mention when you are racing every time you grab for a gear it drops 2K rpm from 8K so it's always @ the sweet spot.

IF it was dropping below the sweet spot then i would push the hondata reflash.

I would like to see 2 cars race
both 06
both with headers
1 reflash
1 with gears

lets see how they compare.
Um k...I am ready to run against any '06....

You sir, are correct...I don't have a real understanding of how Hondata did their stuff. But I know that stock...and even now with my EMS I can go above my VTEC engagement point and not be in VTEC...let me check for you ok.

My VTEC "turns on" at 5400rpm, above -3.81psi load, above 30.08% throttle, and above 2mph, 1.95% more fuel is added to the map in VTEC

VTEC is "turned off" below 5000rpm, below -6.14psi load, below 5% throttle, and at 0mph.


I think to be positive you should check your own...I know you were the first to be chipped and also involved in the process, but why Hondata would want to make VTEC engage at 20% throttle and 6100rpm doesn't make sense to me (though I do understand it is impractle to reach 6100rpm and hold it at 20% throttle...it is doable especially downhill in lower gears where much power isn't needed at slow speeds).

Also, just wondering, how much more, if any, power was added when you switched from your chipped ECU to the EMS? Didn't you go to shawn? What were your numbers on his dyno if you did?

Of course I am correct...I know my shit!

The reason for a "VTEC window" is for fuel economy.

For simplicity sake let me break it down like this:

1. My car made 230rwhp bone stock (on Shawn's dynpack).
2. My car made 235rwhp with the Invidia exhaust (on Shawn's dynapack).
3. My car made 246rwhp with Invidia exhaust, Toda header, J's Racing straight pipe, AEM CAI, Hondata IMG and Hondata ECU reflash (on Shawn's dynapack).
4. My car made 225rwhp with Invidia exhaust, Toda header, J's Racing straight pipe, AEM CAI, Hondata IMG and Hondata ECU reflash (on AutoWave's dymamometer).
5. My car made 213rwhp with Spugen custom 3" single exhaust, Toda header, AEM CAI, Hondata IMG and AEM EMS (on AutoWave's dymamometer). It made no difference whether I used the Hondata reflash or AEM EMS--the car made the same power.

Needless to say I am not happy with the results from the single exhaust Spugen made. My car lost 12rwhp! Not good at all.
a 12hp loss...wow...definitly something to fix there, needless to say though, with how your car was setup previously (#3/4) you were making about 10hp more then me. Though I didn't have a header or Hondata IMG at the time.

i tested this very theory that your are saying... but on my 06 i notice if i have 30% throttle and i swing past 6K the Vtec still kicks in reguardless. The RPMS @ 6K skyrocket very fast compared to 4-5 and 5-6K.

i know they are stating that the Vtec window is only actinve with 40-50% thorttle modulation but i have tested this for several days now. So Vtec is on when it's set at a specified RPM the amount or the degree that you feel is dependent on how much you stomp on the go pedal.


My thing about engine weare is crusing @ 70mph your right around 4300-4500RPM @ 6th gear, just a slight adjustment of the throttle Vtec is on and you take off like a skyrocket. i would not want this feeling, if the Vtec point is at 5K then i think it's ideal. 4K is too low thats crusing speed, at least if you know your going to race you have to drop 1 gear which sets you up around 5K or so then it's usefull.
