Anyone done this....When i had my h22 put in, I did not get the p13 ecu, instead I kept the h23 ecu an my mechanic wired up VTEC to a switch, so i can activate it anytime i want, the only problem is......I have fuel cut off at like 7200 which kind of sucks, but i have not ran it in the 1/4 mile or done a dyno test so i really cant tell you how it is? uhhh is this stupid? any comments at all is all good...

 

the only real downside to that is the rev limiter being so low, i was gonna just use my LS ECU when i built my LS/VTEC and use an RPM switch, but managed to get my own ECU, but yeah, that's not a bad idea, just suck that you are hitting rev limit when you should be making the most power

 

yeah, but like is my low end power suffering with this ecu?

 

low end prbably isn't, you high end will suffer more, b/c it's not adding more fuel after VTEC engagment like it should

 

o well he (the mechanic) said that the switch controls VTEC, more fuel, and something in the intake manifold to allow more air...

 

the "something" on the intake manifold was also on you H23, so it should engage as well, that shouldn't be affected

 

hmmm alright thats cool, do you understand the "fuel" thing though, an would it be a good invertment for say a chipped p28 ecu?

of course. it would be Honda reliable ( to an extent). , insted of an rpm activation switch. that is whatcha got isnt it?

 

ummm i guess if thats what you want to call it, it just a switch that i hit to change over to vtec, hit it again an im out of vtec, lol, i dont know what you call it

that sounds prety dangerous to me. if i was you i would DEFINETLY invest in a new ecu. so you have to push a button when you want to engage vtec?

 

yup, its a switch......hmmm i dont know what to think? what about a p28 chipped spoon ecu off of ebay? is it just a plug an play thing when you install it or what

i wouldn't trust anything off of ebay (as far as ecus are concerned). if i was you i would try to find a company that sells ecus. which one to get is a matter of opinion, p28, p72 have their plus and minuses (do a search on this) but you must have both of these setup to run on an h22. if money is a concern or just want the correct ecu, buy a p13. there are a number of different opinions on which ecu is best. once you do the search you should be able to find the best ecu for your setup/ plans for the car.
