Will a D-series ecu such as P28 work for B-series B16 B18 Vtec ETC?

 

for chipping/socketing purposes, yes.

wouldn't run your car stock with a virgin p28 though

 

yes but not very good without chipping

 

my understanding is that P28's are extremely versitile, and work with pretty much any swap.. after modifying its program of course. i know for a fact that some people even run them on H series also.

 

Why would it not work so good, because it is for a single cam and not dual?

 

becuase its meant and originally programmed for a single over head cam. If you use it for a dual over head cam you are not getting the full power of the motor. Its like having a b18c5 using an ls ecu or b16 ecu.

Its better to have the ecu match the motor mods by chipping or flashing or hondata or whatever.

 

if you use a non-vtec ecu lets say Auto LS P74 will that work with the b16 motor, just no vtec?

 

if you use a non-vtec ecu lets say Auto LS P74 or P75 will that work with the b16 motor, just no vtec?

wth are you talking about, you not swapping a jet ecu to a car

there are no sensors on each individual cam, and the engine cycle is still the same with single or dual cam. if you chip the ecu and tune the car properly you should get "the full power"

you can modify those to support vtec as well, there is a website where they sell kits to convert ecus to add additional route from the processor for vtec

 

Thanks Qaz, so without chipping p28 it wont run good on B-series.

Also just bare with me on this, if I were to use P74 or P75 from ls on b16 even tho it is not vtec, is the engine still going to run right, it just wont utilize vtec?

 

i never tried it but i don't see why not, i am more than sure that it will run but no vtec

 

So in that sense can you run a Vtec ecu on a non vtec?

It would not be a wise choice.

Yes.

 

im currently runnin a p28 on my b16 but the car dies

 

dude each motor has individual parameters for fuel and spark. the b16 isnt just a vtec motor. its got higher compression, uses more fuel, different timing than an ls. get a chipped ECU, or get a direct replacement b16 ecu. dont be a dsm hack

^ This guy is obviously talking out of his ****. Don't be ignorant! Thousands of wrenchheads have put together B16's using P28 ecu's. Chipping an ecu is one thing, you have to actually know what you're inputing into the new chip to make the motor run properly. A P28 will work properly "only" if it's been socketed and reflashed with the correct maps ie. air fuel ratios, partial throttle, WOT, etc. Alot of tuners use programs such as Crome, Etune, Hondata, Uberdata, etc to rewrite these "parameters", hence you get a Tuned motor out of it. Do not attempt this on your own without proper research. If you are a DIY type of nut, there are readily available information here in cyberspace for your sponge of a brain to absorb.

No, he does know what he's talking about. He pretty much said don't just use a P74 ecu with a B16 without having it chipped with a proper base map or tune on it.

Que??? Where did anyone say anything about using a P74 with a B16? I'm referring to to OP's original question.

 

i was running a p28 ECu on my b16A civic but i had it chippd.

 

Can using a virgin p28 cause an ls vtec to stop making power at 5k rpms? Another question is does the obd1 p72 look for a knock sensor?

 

Yes, GS-R's have a knock sensor, so the P72 will look for it.

 

I have a question, what would be the best ecu chip to use in a p28?

 

bump

 

If you don't know how to use Chrome and those sort of programs, order one off of Phearable.net and don't get those "Spoon" chips from Ebay because they won't do anything other than waste your money.
