engine questions

[codeunknown]

Hi all...recently i had a engine fitted from a wreckers..a good engine too! however i am wondering what it was from? as in what holden ? and what series it is.....the old engine was a VH XXX XXX and i was told that was a vt engine...series 1 found in vt's only.....the replacement is VA XXX XXX as far as i know nothing was changed in computer of anything...it was a staight heart for heart transplant......

so if someone can clear this up for me it be great... cause i got a second question?

my son bought a vs and its a equip......the original engine from it was removed and replaced ....
i like to know what it would have had in it as in V? series engine...and what series run..as in 1 or 2...

his issue is ...its now got a VA XXX XXX as well....which we dont know what they are ...be that series 1 or 2 and out of what holden?
the problem he has ...is the rear of the engine has clip wire point..we think is the ECU connector?
the car runs but sucks -- drinks fuel without this clipped...our question is how to clip this VA engine to vs harness...
is it a simple job or what...?
what do we do ...to get it going...?
If its not the ECU what is is it,,,because its the only connector we found unlinked...and the vs is sucking 5l/100km more than it should...

If we need ask question 2 in the vs section a ok

so we like to find out what we got...first and from what...most likely donour...
what series they are?

and in my sons case what do we need to do to complete his cars transplanet from old engine to this new one in the vs..

Many thanks

ok so we got a vx donour engines...around 2000--2001...kewl.... however how do we know if there series 1 or 2 or can they only be 1 series?

also the vx engine into the vs equipe......we have 1 rear clip point...unconnected..? what is it and do we need it connected and how do we do it

I think that you are talking about the EGR Valve, VX Commodores came out with the EGR Valve and VS Commodores didn't, so there is no need to connect it. Is it on the left side of the engine towards the rear? If so then it will be the EGR Valve.

I'm really not sure if the car it came out of was a series 1 or 2, but all I know is that all ecotec V6's from VS to VY including supercharged V6's all have "series 2" stamped on the engine block (on the right side I think from memory).

any reason why...this vx engine in my sons vs equipe is eating more fuel...?

also we see ...vx engines develope 229hp ...and standard vt and vs engines vh series 1 and 2..do 201hp...holden state the difference in vx (va series ) engine vs vt (series VH engine) is the cpu and its mapping settings..so basically chipset...so should ....my vt with the vx engine should be running a vx computer ? and should my sons vs be running a vs computer ?

we dont know why my sons engine the same as mine ..in his car is chewing fuel..its a younger run engine to mine..build date and id number...and appears to be the same shape..we not compression tested them..however the only difference we see is possible ecu / transmission / diff...but his chewing 5/100kms more is excessive over mine..we looking at the why's...??? are there any other things we should look at..? to start with... if we had a vx manual just for the engine..it be helpful..and of course a vt and vs man would also be helpful to compare...in the main we sorting the sons car out so its good on fuel and fix the defects..for stable ride ty all keep the info flowing

Yes you are right, the different in the power in the tune in the ecu. The VS should have a VS ecu because a VX ecu wont work in it. (I'm not sure if VX ecu works in a VT).

The engine and ecu may not even be the cause for it using fuel. It could be faulty oxygen sensors, the air temperature sensor, blocked air filter, etc. I get about 10L per 100kms in my WH Statesman (which has the same engine as a VX), but it also depends how the car is driven (heavy acceleration = using more fuel).

thanks
we tested the vs vers vt on the same run...
both cars the same conditions..and same load
both on the same fuel
same tyre pressure
we did this due to the now known EGR we thought was a ECU link..
so we drove same loads full fuel same speeds...same distance to compare...
the vt with the vx engine 18litres for 200kms...wet weather driving..highway
the vs with the vx engine 28litres for 200kms...wet weather driving..highway
so clearly the vs has a issue...slurping 5 litres /100kms more

what we do is check the air filter...spark plugs...spark leads ...battery and earth...
then see what o2 sensors and air temps sensors are like..

if anyone can think of others..specailly known ones with the vx engine..please let us know..
i seem to lean towards over enrichment.....
just dont know what and where....
and are looking for some tell tails..

also error coding....will it be in error code ...and how to do we get it and read it..and work out what it is?

anyways keep the info flowing..
thanks

If the oxygen sensors are faulty they will cause it to run rich and use more fuel.

If you check the error codes then the oxygen sensors will log a code if they are faulty.

If you haven't done a tune up or not sure when the last tune up was done, then I would recommend replacing the fuel filter, air filter, spark plugs, and spark plug leads. Maybe even get the fuel injectors cleaned out/checked.

Other then that, there is not much more info I can think of to give you, but someone else here might have some other ideas/suggestions.

Let us know what the problem is when you find it

try cleaning the MAF with contact cleaner and perform an ECU reset

here is a little update...the car was overheating ..or we thought so...so we done the following given what we found...1) gunge 1/2 inch thick in overflow tank..from standing for years and no use of coolant..in the past and scrappy line build up...so that got flushed back to perfect....2)flushed the hot water heater system perfect clean..3) hot flushed and cold flushed the engine and rad and lines ..the rad appears to be recent and new...same with some lines...water pump makes no noise ..but we still are suspect ..given past grunge..so we watching the pump with a view to replace...the thermostate was ZERO...none in there..a reason for fuel eating on cold wet day..running! so we fitting one asap!
the other of interest is sensor and temp sender on vx engine....and reader and cpu of vs....could be calibration difference...or mis match ..or faulty ...testing the running temps..vx in the vs cut in for fan...just past the 1/2 way on dial.. ..and cuts out at 1/2 way....active air con runs fan ok...as well... so the master plan is find out if the sender ..and sensor for vs origninal engine...is the same as the vx sender and sensor....and since we have a vs dial.....and vs computer....we think it best to make sure the engine sensor and temp sender is right for vs....we find out if they use the same gear...as well...we think matching these right should help...and making sure we got good ones reading right is also good idea...we could have faulty sender or sensor..in the vx engine..who knows? but we feeel thsi should help ecu and fuel...thanks for those mentioning the maf and stuff...we hoping we dont need to go all over the engine with remove and test to find it...but first the thermo and sender and sensor if we can ..then we see wht the car throws up in code land...thats the plan....anyway we keep all posted ..because sharing is brilliant ....we wish we had a vx engine manual only....and vs workshop man...would be helpful... many thanks
