intuitively I don't want to go far off the stock program

I'm thinking:

- set vtec to 5100 (down from 5500).. will I lose or gain?

- set the rev limiter to 7500 from 7200

- unlock the top speed.



note sure if I will get these done:

- set check engine light as my shift light (without disrupting normal operation)

- set rev limiter to 4k rpm when car is less than 5km/h (for launching)


any feedback or suggestions.. tweak the parameters.

thanks,

so your idle would be at 4k?
thats retarded imo if its a daily driver.

no, he's talking about setting his 2-step (or launch control) at 4k

Can really tell you when would be the best time for you vtec to kick in. The best way is to go out and get a tune. p28 are the best for tuning IMO when i put a p28 in and got a tuned the vtec crossover was amazing.

do the shiftlight... its worth it if you are getting the chip done.

put vtec at 3500... its sohc anyway... push it for what its worth from the beginning.

uhhh lowering your vtec engagement that low will actually make you lose power. why don't we just wire the vtec solenoid straight to the battery then. that way vtak will always be on! anyways, do yourself a favor. do some real mods before you tinker with all the stuff you just talked about because setting up your 2 step, changing vtec engagement, will not make you any faster on the 1/4 on a stock motor. put some p29 pistons and akmee type r cams (crower st3) and their valvetrain kit and you'll be making more power than b16s. then you should start thinking about when to change the settings you want to change. the only way to tell where to lower your vtec engagement point is on the dyno. your butt dyno can't tell you where it's best.

not everyone wants to tear apart their engine to replace pistons, its not exactly a cost efficient mod if you ask me.

Not everyone is worried about their 1/4 mile time either.

Personally, i'd stick with stock (or close to stock) settings, b/c from my experiences on the dyno, lowering the vtec engagement point will usually lose power, especially on a stock engine. The only time i've had sucess gaining power by changing the vtec crossover point is when the engine has bigger cams and headwork, and then its usually gaining power by raising vtec. Vtec on my car is best at 6000rpms (built b16)....dyno proven.

thanks for the tip.

Like everyone above said dont bother changing your vtec engagement. Vtec should be changed by upping the xover tunning then lowering the xover and tuning again and then compare where WHP xover is on the 2 dyno plots and the set for that, other than that its just guessing and wont result in any gain
Also upping your redline wouldnt be a benifit, the stock redline is there for a reason, as well as your speed governor. Just keep them where they are untill youll benifit from changing them.
The cosmetic stuff CEL shift, FTL, FTS is nice to have. and if you plan on building or tuning for power down the road why not chip your ecu now and have it ready for then.

I think Hondata has a kit for the check engine light as your shift light. I remember reading this a couple of years back but im not 100% sure of which company it was.

hondata and crome both have a check engine light shift light
