hi guys seth strauss here with the how to video on the emerald k6 ecu so on my Golf mk4 r32 we have
an aftermarket ecu so we are going to troubleshoot it we have two problems problem number one is when
we pick up rev's we have a slight lean condition i can see the lean condition on my afr on my ecu as
well as my in car AEM air fuel ratio so how are we gonna troubleshoot this i was looking around
online and i couldn't find anything so i decided to make a youtube video for the emerald k6 ecu
community on my golf mk4 r32 we have an emerald k6 ecu as well as the ME7.1 harness adapter for the
golf mk4 32 take note this is only on the golf mk4 platform so this harness plugs into your standard
cars wiring and then plugs into the 36 pin ecu connector so i was looking around
for my afr wideband signal which got lost somehow found it to be a loose ground connection on my
wideband module so we fixed that but while we were in the touching wires i had the car go LEAN
i'll add that video right now for you guys to see
so we're going to use the de-pinning tool i created my own de-pinning tool uh i'll post
a link on emerald site where they have a pdf for the de-pinning tool how to use it on the 36 pin
so we're gonna de-pin injector number four this is the cable that we found to be the
one causing the LEAN condition so how the spin de-pinning works is inside our 36 pin
this is the bottom of the 36 pin so there's a small plastic tab you have to grab
and lift to the top side and then you pull the cable from behind
like that so now we're going to test continuity between this point and injector number four
so now we're testing continuity through the
harness through the car's wiring to injector number four remove this wire
sorry that's me
so all seems fine let's plug this back into the ecu
over here start the car wiggle the wire and see whether we fix the problem
so over here we can see it's not sitting so snug
we'll try and rectify that
so when putting back the clip we should hear it clip in into position
did you hear that?
so let's test it
so over here we are idling at just under 1000 rpm our afr's are 12 which is a bit rich
this is a cold start sorry about that
just a slight throttle changes just to hear whether it's picking up smoothly
so
so after idling a few minutes uh we will check we will check
the loose connection again let me just switch on my light sorry for the shaky camera
so this is the pin
see i can wiggle it
so we have a good connection thanks please like and subscribe
