Update:

installed the 950cc injectors yesterday, had some issues, after i got the fueling ok the engine only ran on 2 celynders, it turned out to be 2 injectors not working...so I gave them some electrical resussitation.....and walla....running on all 4's

I am worried though....I reduced my overall trim from 39% to 0 because the injectors are huge....on my fuel map it idles at over 2 ms....for 950cc thats alot of fuel to idle....isn't it????

So the question begs....is it 950cc :evil: :?:

I took an injector out again today and made a home test kit....turns out the 950's are not 950's.....they turned out to be 750's....

I at least have 750cc's to work with.....not what I bought but at least....

Now the question is....why is the ms's so high on idle???????

So...got into some tuning....got the idle nice and stable, preceously when I drove and the car went into boost the engine smothered and almost died....now I got it as far as boosting and pulling hard to 7000rpm.

Still have to sort the lower middle of the fuel map out, has some hesitation/smother before it starts gunning....as soon as I am allowed time again :roll: I can try and sort that....

Starts very good and it seems I have the temp adjustments close to home....

Had a few minutes again :roll: ...got the stumble lower in the rev range, it is now before boost, then it pulls like a mofo....still abit lean over the whole range, already datalogged and adjusted fuel map...just need to load and see what it does.

As for my high ms problem, I found out it is because of injector latency, after some more research and asking myself alot of questions and research, I found that my battery voltage compensation table will help rectify the injector "dead time" or latency....you normally get a table form the injector manufacturer to compinsate....unfortunately I don't have a clue what injectors it is so I won't have the correct compensation table.

Of what I have researched, the dead time increases as the volts decrease and revs climb....so I have to play it by "ear"...I will generally increase the voltage compensation curve to get it somehwere near the ball park...and better than it is now.

I orgenized some free time on saterday, got in the car, loaded the richer map with the voltage comp. It made one hell of a difference, the car idled sick because of the voltage compens....so I sat a bit sorting the idle....what do you know...it did not idle at over 2 ms any more....

After that was sort, I started to leave my home, was on my way to Charl to do some data logging and in one shot sommer see the Z32 the bugger got.

So I started to drive, I pretty soon saw that the richer map + the voltage compens. was heavy overfueling...did not want to boost and spitting dark clouds...so I stopped at a place and loaded the leaner map i had before and just added the voltage compensation...

All I can say is that the acceleration was scary, hesitation gone, it pulled like a demon, I can honestly say I had shivers.....then I turned on the datalogging and wanted to do a few 3rd gear pulles at different boost levels....and then.....

For one thing...the first...the computer frose up(laptop)....then I heard the sound I have heard before....the turbo hitting the engine mount on boost ( some time back the same thing happend and after investigating I found that the engine flexed so much under boost that the compression housing hit the engine mounting...so I took a piece of the mounting off) while I was busy I decided to make the mounting solid...so how it is hitting now I am still to investigate.

In anycase, it seems that this caused a leak between the turbo and manifold....it now leaks so bad that there is very little acceleration....it sounds like a tractor....

I at least now know 2 things, the voltage compensation makes one hell of a difference and that my fuel map is close to the ball park....

My car did that once. It sounded like a tracktor them I keept on re tightning the turbo to the manifold and same shit . My problem was the studs keept comming lose so I had to tighten the studs then lock up the turbo.
