hello my honda family today i want to make some videos to show you the differences between some
ecu's what's needed for tuning and basically the um easiest and cheapest way i found a tune
a lot of people have asked questions so this will be part one of a video series
this part will be identifying your ecu's so on the top right here
or maybe to the left depending on how this video is recording is a p28 ecu below it is a p06 ecu
so basically if you want to tune obd1 honda you're going to need an obd-1 ecu that's chippable
so you'll have a pin socket here and you see this one i've already chipped
it's got a machine socket down there identically a po6 and a p28 are identically electrical they do
the same thing except the po6 does not have the transistor which is located right here
and a few other components to activate the vtec circuit
so yes it will run a vtec engine but you will throw a check engine light unless you add that
sk chip right here and a few other diodes and capacitors so
first step in tuning is pick yourself up p28 p06 p72 obd-1 on the ecu basically with three plugs
i believe it's a b and d are the plugs so you pick yourself up one of those ecu's and make sure it's
working so i'm going to start out with the easiest and the cheapest ecu which would be the po6
because everybody wants p28s so we'll zoom in
all right so
when you have a po6 ecu you're going to have some serial numbers up here in the in the board
you'll have a 1500 i think you'll have a 1720 and an 11 fo board so that's going to designate what
type of circuit board is here and what type of sk chips and diodes you'll need to convert this to
a vtec ecu so i happen to have one already that i have desoldered and all that good
stuff so i'll move this ecu out of the way and i'll get the one that i've already taken apart
all right
so if you look closely the areas that you're going to have to work in to start getting the tune
is going to be this area here you're going to need to add a 28-pin chip you're going
to need to add the 373 chip a lot of people don't add the c51 and the c52 but i add them
uh you got to have the j1 and the r54 jumper down there
i also you also want the cn2 data logging port if you want to be able to data log
i like to change the capacitors c14 c201 c15 c24 c21 c19 c18
and c40 they're nearing 30 years old and they tend to leak so you want to change them
so if you're at this point in tuning you should pretty much know how to desolder
and solder components in if not you drop a message down below i can hook you up
but i'm gonna get all these components in soldered in and then we're gonna take a look at it
actually before i solder these components in let's back up and look at the components
that you're gonna need in order to start tuning your ecu basically chip and tune it
so you're gonna need a whole bunch of capacitors
there's eight of them there
you're going to need a chipping kit with a sst chip i got a zero enforcement
socket so i can quickly change out chips machined 28 pin that is your 737 small chip your cn2 data
logging port your vtec controls because remember this is a p06 ecu that i'm turning into a p28
and then all of your c51 c52 r54 and your j1 jumper to make the
p06 read off of your custom file on here so you're basically going to need all that to
go ahead and start to get tuning so we'll wrap up this first video here
and we'll move on to the second video of component installing thanks for watching please subscribe
