Tuners Rejoice! Free Tuning For M4.4!


Recommended Posts

I'm not aware of myself stating that these thing are 100% truth, it might have been my enthusiasm taking over.

These are my findings and because I'm happy with the results I like to share them and so I did.

Thanks for the additions to my posts, you sure have a point in these about the mixture.

With you now thinking I have personal problems with ya ur also taking things personal.

This is not my intention, for sure I will sent u some PM still thinking about the content :P

i am after a little help

i am posting a log off tuner pro, after reading through this mass of fantastic information, i believe this is the correct place to ask for a little help !

i am currently finding my way around this 4.4 tuning but have stumbled across a problem that some of the veterans may have a easy answer for .

i have a 850 t5 running 4.4 with no issues (with greens), but i am about to install a k24 to go with other mods that i have done,but am using my spare 4.4 ecu to get used to altering and seeing changes where adjustments have been made .

my issue : 

car starts from cold ok but mil light on ,once warmed up starting it again is a real issue i have logged my most recent run.

i from my observations is that maf maxes out at 2k (a standard map ) and system voltage is very low as well i am wandering is the voltage issue contributing to the maf issue?

any input appreciated .

(-is advance and +is retard)

:blink:  Well now I'm even more confused?

Am i wrong, or don't most people associate minus (-) with retarding the timing, and plus (+) with advancing?

But that's not even the question I was asking..  I was asking which cam (intake or exhaust) was advanced and which was retarded; you didn't say in the post I was asking about:

That is how we ended up with -2,+4

Gehe, I more or less forgot to give you a decent answer because of the discussion with boxman.

The + and - story seemed rather logic in Dutch :a-farmboy:

So exhaust cam was 2 degrees advanced and inlet cam 4 degrees retarded.

So exhaust opens 2 degrees earlier and inlet closes 4 degrees later.

Less overlap and longer time for cylinder filling.

Hey guys, Long time lurker here.

 

So I think I finally found out the Green injector Mystery.

The green Injectors flow 415cc @ 3 bar NOT 440CC at 3 bar.

 

Did not anyone think it was strange that it was said they flow 440cc @ 3 bar and 465 @ 3.8? 

 

Here is the Solution it comes like this. There are two "green" injectors.

 

Ones are Green TOPS PN :0280 150 558 which flow 440cc @ 3 bar these are FORD injectors

The others are the GREEN GIANTS PN: 0 280 155 968  which flow 415cc @ 3 bar

The confusion comes from http://www.ctsturbo.com/cart/products/Bosch_42lb_440cc_Green_Giant_High_Impedance_Injector-256-4.html 

 

Listing both :
Bosch 0 280 155 968 ( 0280155968 )
Bosch 0 280 150 558 ( 0280150558 )

as reference numbers.

 

Now when we do the calculations for the VOLVO green giants they are 415 cc @ 3bar , 465cc at 3.8 bar and 478cc @ 4 bar. It all makes sense now:

Use http://www.witchhunter.com/injectorcalc1.php for the calculations. When you do it this way it makes sense and it corresponds with flow testing done at a shop for the Volvo Green giants which flows around 415-420CC at 3 bar. :)

I hope this helps.

 

I suggest the M4.4 wiki is updated too.

It's a bit more complicated I'am afraid.

I've tested (volvo) greens 0 280 155 968 to be 448 cc at 3 bar:

There are two different types of  greens though 415 and 448 cc, but  not being the ford injectors.

 Man that just makes it more complicated.

 

Were those out of a S60R/V70R p2 or a 2000 V70R.

Maybe the 415cc are the 2000V70R and the 448 are the P2 S/V -R's?

 

Are the PN the same for the P80 and P2 greens?
