map sensor

i have a question in the fuel managment. if i chip my ecu and use 450 cc injectors that mean i need no missing link and i can install my factory map sensor ?

If you are boosting your car, your factory MAP is good for roughly 12 psi. But, anything over around 8 psi, I would look int a aftermarket MAP, or a missing link.

you are chipping what and running what to control your 450s?

anything over .75 bar is a need for a 3 bar map sensor or, you could just richen up the last columns on the fuel map.

i will chip some kind i pay on ebay it cost 20$ and my ecu is p28. and my turbo is t3/t4 which design for d15 and my motor is d15b jdm vtec and suppose be be 130 hp without turbo

so what if we are running a supercharger with 9.5psi? the missing link is useless because the intake manifold is pressurized. so what would happen if the factory map sensor is used?

Unless you are running a chipped ECU, such as chrome, Neptune, Hondata, and you are using thr FMU. The FMU jumps the fuel pressure up under boost.

Maybe I read this wrong, but if you're talking about buying one of those cheap $20 e-bay chips, don't do it. Those thing are garbage. It will give you more fuel, but it's not going to be good enough for boost. You will need to get something that is specifically for boost. I know you said previously that there isn't anyone around you that can tune your car, but you might want to consider something like the Apexi or greddy emanage, that will be preprogrammed for you.

i will tell you things i had tell now
injectors 450cc from ebay , fmu blox 1:12, fuel pump walpro from ebay, cheep turbo chip for the p28 from e bay, missing link
i know if i use the fmu with missing link with the fuel pump only is good. but not good for high boost.
so what is your suggesion ?

hey hany,

those chips you are buying off ebay are useless. you have nothing to control your injectors. you are running an fmu with the injectors?

youve been posting many questions lately and i dont think you are really reading the links that are provided to you. so, here it is a very good supply of information for you to cover engine managemnt issues. search the archives in those links and go through all the faqs. dont start buying things without researching and figuring out why you are buying it and what it is for. if you want to play you got to pay. not to mention figure out what you are doing. read the links. they are an excellent source and reference on your engine management questions.

the best suggestion you will recieve is from reading and searching through those links. there is alot of info, but, theres no need to rush either.

my problem is my country is very very poor in info about the turbo and no one here sell any turbo parts. so i buy every thing from e bay. i know the the perfect managment is to use hondadata with the 450cc injectors. but hondadata is expensive for me . i read about upperdata i think i send them the ecu and them chip it and send to me later. but i cant arrive them.
any way i will read again your sites and if face me problem i will send you.

about that words (if you want to play you got to pay) we have in our country some words like that we say ( there are no sweet without heat ) :)
any way thanks for help . i will mail you at the right time
