Hyosung gt250 efi ( 2008 SENTEC ) sensor replacement

[Dan]

Hi all!

I have a project on the go but have run into a few issues. Mainly SENTEC parts no longer being available. I need a MAP sensor, throttle position and idle speed control unit

 

Surely as long as they are for the right engine size, couldn’t I buy a new style sensor and change the engine harness side connector to match?

 

Thanks in advance!

Sentec sometimes uses Daewoo parts so , this is an area of ambuguity until things got finalised in 2014 when all things was just delphi for delphi (every little thing)

So can you post pictures of your parts that’s present on the bike , so i can see if i have old versions on ebay that could help.

Namely these only as you said “MAP sensor, throttle position and idle speed control unit”

I don’t actually have the TP ot ISC. But here’s pictures. I could actually use a fuel tank and full fuel system as well only tank pump to the throttle body line. I have that bit
And yes it’s mounted in a GV frame

(shown in last pic)

The map sensors are used in some jaguars but I cannot remember the part number also the sentec system doesn’t have a tps

37920H88600 is tge part number of map. And thank you. I didnt know haha! EFI is relatively new to me

Lamda Sensor , and certain EFi sensors actually come from Hyosung MS3 250 Scooter  (which is a super rare scooter in this country)

I’ve ever only worked on a sentec bike maybe 3 times ,  as simon said , never saw a TPS module that’s why i wanted to see your pictures as to where the TPS is.

It might be my eyes but i see 1x air sensor (Delphi type) on one throttle body,  if it says “Delphi” on it.         The “Mini Harness” that is connecting the throttle body sensors will have numbers like 12345 (DEL)  , then it means  (DEL) for  Early Delphi unit.  with a green tag  ,  daewoo is yellow tag most of the time.

So have a Sentec GV harness , I have not found any other compatible harnesses.  GV is harder than GT.  Sentec is for Sentec.  However it is possible to find yourself some sensors from a 2007/2008 GT250  (only one)   , as after 2009 it was all Daewoo & Delphi afterwards

Hi mate!

It’s a GT harness im kind of making work so far it’s just this sensor. I can’t make out what the sensor says on it other than “Hitachi” as its faded. Youre right I have one sensor cant figure out what i did with the other

Yeah retrofitting a GT harness in to a GV is a whole different ball game , not something most people talk about , its actually rare , so you are pretty much in uncharted waters!   Good luck .

If that hitachi thing is close to the cylinder head, it is probably injector but can’t tell as i can’t see the throttle body fully and how it goes in.

I have everything working spark, turns over lights, had to spur off and make my own connections for things but wasn’t overly difficult once I had a wiring diagram and started drawing my own up. Custom lights, indicators, speedo. All working. Thankfully its a GT engine which could have helped because I’m not great at mechanical stuff but wires are wires. Just fancy colours. Complete the circuit, send a signal, get a result. Just hated the maths to be honest haha! Original harness can be restored in 30 mins. Rip it off the bike and detach my stuff and good to sell as original.

That hitachi thing is the map sensor. Definitely not injectors.

[Simon]

The Hitachi is one of the map sensors there is one on each intake they are used on jaguars but can’t remember which one

[Dan]

Cheers buddy. I’ll try the car lart place near me.. any idea what the hyo part number is or any identifying numbers?

I’m pretty sure it is this one
