the problem i am having is that i cannot hear vtec activating, or its just activating very early. the main problem that is really aggrivating, is that my power seems to faceplant at 5.5k. After 5.5k it sounds like the engine is trying really hard but isn't getting anywhere fast. could this just be a tuning problem too lean or too rich maybe?. my ecu is a chipped p28

 

Your problem is more than likely the chipped p28. Chipped ECU's are a waste of money and time. I would highly recommend the stock ecu or a unit like Hondata to control your fueling and ignition tables.

 

why are they a waste? are they not as in-depth as a hondata system?

 

I have to completely disagree with precisionh23a..., I have a p06, that I chipped and converted to a p72, using crome pro with an ostrich 2.0 emulator, and a hulog datalogger... I plug my car into my laptop like an ipod and control everything in real time, including when and how long you want vtec to kick in... you can run in closed loop, or open loop, or just choose which sensors you want working.., without ever needing to burn a chip..., sure you can stay stock,,, if you want to limit yourself and get smoked by someone with a map setup thats adapted to his or her car..,

here is a vid of my car last summer, with a slightly modded p13 map on my converted p72... it says p28 I meant to type p72... <---iv'e gotten so much **** for that

i have no idea why it shows two vid links.., i asure you I only put one

June of last summer---\/

anyway, is your p28 chipped with a p13 map, or is it a virgin p28
I hope your not running a virgin p28.., but I don't think your car would be running as good as it does if it wasn't chipped....,

if it is chipped, and if you have a stock intake manifold, then your intake butterflys are idle..., lots of people have different opinions about using them or not..., use them if you have them.., I sure as hell notice a difference.., especially since I can choose when I want them to open..,, you would have to buy a couple dollars worth of hardware and soldier them into your p28 to make it a p72.. so you can enable your IAB's..,

I don't think iab's are your problem though.., I think its most likely problems associated with having incorrect map settings, especially if you have smaller diameter wheels on a super light car,, like an "eg"

adjustable cam gears and perfect ignition timing are key..,

do you go do all your car **** yourself, like timing light, idle adjustment and what not.... any cel's...


sounds like your cars power curve is come and gone before your engines full potential output is reached, I had to put 18" rims on my 3g prelude to increase torque, and I still burn out in two gears...,

having a light car using stock maps would cause all around limitations.., i'm sure you can understand why..., you just need to get your motor adjusted to your car..., its not just a one time "buy a chip" and wala.., its a process that takes a little time,, thats why an emulator is the only choice

 

i have no CEL's, i haven't done anything regarding this problem, im just trying to figure out whether or not i should just get a p13 or take my car to a shop so they can tune the p28

 

If you dont know what is in your p28 stop rev'in it. get a good basemap untill you tune the car, otherwise run stock.

i have no idea why precisionh23a would say somthing like that. thats completely false.

 

what mods are done to the car? and where did you get the chip? a chipped ecu should work perfectly fine for your car as long as it programed properly for your engine. also a chipped ecu is the first step to tuning but the car will only run as good as tuning software tells it to. if you have some unknown basemap then i could see the car running poorly. my suggestion is to get a tuner to burn a new h22 map or go ahead and have a full tune done (more expensive option, obviously)

 

if you bought an emulator, I got a few good starting basemaps you can have, so you don't have to go and pay someone to tune.., but if you did go to a tuner, it would make things a hell of a lot easier for him.,, if you had an emulator

its like a "tunner in a box" say bye, bye to ever burning another chip

just ask all the turbo junkies, I bet most or all of them use an emulator of some sort.., just think of how many chips they would go through, or how many times they have bunt a new map on a chip.., its an ongoing process, this eliminates all the work so you can concentrate on the tune at hand.

 

^---- finally, someone else that knows what there talking about---> dpetro1

 

so i plugged in a stock p28, i just wanted to try it out. so i did one pull in 2nd, i could hear a vtec cross over and held power nicely until i let off at 7k. im starting to think that maybe my chip just has a bad map on it

 

ttt

 

get a new map burned on your chipped ecu and see what happens. since you have an unknown chip now we cant really say why it isnt performing well. dont run a factory p28 for too long as its a 1.6l sohc ecu. timing and fuel will be incorrect for your h22

 

i know the virgin p28 is a no go for a h22 but that was just to see if vtec was even working. everything is pointing towards the chip in my ecu. i ordered a new chip today, so we'll see what happens

 

who did you order from? and what exactly did you order? just a stock h22 chip?

 

so,how much would this setup cost?

 

i ordered from phearable.com, buddy of mine got an ecu from them and his car ran great. its just a basemap tweaked a bit for full bolt ons. and the emulator is like 300 i believe. for that i'd rather just go hondata since the tuner i would go to uses ectune and you dont technically need the emulator.(correct me if i'm wrong)

 

you won't ever need an emulator if you always go to your tuner for changes.... costly...
your tune will take some time..., you won't be dependent on your tuner if you can create and edit your own maps.... it's real easy man, it doesn't take very long to get the hang of it.., you can use it on whichever software you choose
