Yes we pushed it further to het the "magical" number and to see where injector ran out ( and other factors ) then you bring it back and do a "few back to backs" on the dyno quick to make sure its on the realm of "safe"

    Start 200rwkw 11/11.5afr



    Finish 248rwkw 12.2afr ........
    As u can see the back to back runs



    And heres boost



    Then after a good cool down we go for the "print out number"



    Ive given a bunch of info off these graphs have a look and a think and see how we managed to gain 54rwkw over 90 engine hp off a "tune only" situation

    Biggest part is having the car mechanically A1 to start with !

    All done on hp tuners in about 4hrs
    Would be interesting to see how lean it went on your back up run if you went to the same rpm as the original run...
    Just not my style.

    Not one of our cars had 12.7 afr where did u get that from ?

    12.1-12.2 at a maximum up top for this car and remembering you need to see where things fall over to know how and what to advise to up grade !!

    Unless otherwise always target 11.8-12.0 or lambda 0.8 !!

    This was the end afr after we installed the 60's and the point of all this was to show where things fall over hope it helps out

    Obviously the 273rwkw was the final tune with the 275rwkw being the "print out" run

    12.7 AFR was where this car was with stated mods at 7.5 psi. Obviously the basic mods worked quite well resulting in using up the available fuel hence requiring bigger injectors.

    I will target the target table target AFR that I chose and make it match as best I can.

    What hi speed afr gauge are u using ?

    The point of all of this was to show that around 10psi it gets its max IDC on stockers

    My LC-1 cost $200 my LM-2 cost $450 my D/D hi speed cost $1500 .....

    Yes all three at the same time and results differ

    Where do u have it plumbed in at ?

    Got logs to show ? Where does it lean out ?

    From all my ramblings i gave a clue what throws its hands up first in the line up considering you have done this i take it you have a new filter ?

    Hi speed is key the best of the best is autronic imho

    If u want help with this further info is needed

    When is it leaning out ?
    Wheres the power graph ?
    Got any logs ?
    Are you using a dyno ?
    Have you checked the total fuel system for pressures ?
    Have u tweaked the stock scalers ?

    Anything helps !

    Thanks but I have already explained that I determined the injectors were maxed out in a previous reply to Daryl I believe.
    Was 220 odd now 285kww. Yes using dyno.

    I have fitted id 1000s.

    Once I have finished for sure.
    Jet you may be able to help me though. Fuel trims at idle/ low medium load are bang on and +- 2% trim however in open loop am about 8% rich. How have you found the id settings or have I missed something?

    Id's are so good from the data supplied but all injectors need to be scaled correctly

    I would start with the data you got, make sure its current and then look how you entered it into hp

    Thanks, sure its current. Injector Dynamics and HP don't look at hi and low slopes in reverse do they? I have a data sheet for KPM 1000s and it appears their data is "reversed" as far as the hi and low slope go?

    KPM's data is spastic at best

    No id have it set up correctly if your using the latest online data entry page

    using a multimeter or oscilloscope will tell you what duty cycle you are actually getting, not this rubbish 110%, how the hell do you get 110% (not doubting that is what is recorded as I have heard of this heaps from scanners)

    Very interesting Jet, it seems to confirm what I said before that you cant run 10lb boost up high. You seem to have lopped of 20kph off the top of the cars 4 gear and you are out of 10psi by about 135kph.

    Also running 95% duty cycle and higher AFR as previously posted (my calculations were at lambda 0.79). But it does go to show that my estimates are slightly conservative.

    Did you adjust fuel pressure at all?

    Thanks for posting this up, very valuable and a treasure trove of information.

    Darryl.

    Daz no problems but there was a reason why i showed what i have and your eye is seeing what we did to combat this issue

    10 psi down to 9 at the end kept the afr in check ( well as lean as i was going to let it go for this example )

    Yes you can run 12 psi on stock squirters and maintain a decent afr as long as it tapers off respectiably, you might start to gather the ford combo is always a "seasaw" effect everywhere !! This is also why good tunes can take a long time !!

    Suss the graph we went nearly 40 pull on this car to get something we were happy with

    Any real tune takes many many pulls unless your cheating and doing copy/paste tunes
    We have had tunes blow into the 100 zone for the chase of quality or a happy balance, those graphs ive put up are for everyones help on what you should see when stock parts run out, this was not to show off but to show what happens clearly and the more you guys look at tunes/graphs the more it becomes clear what the tuner was trying to do, this being said its superrrrrrrrr common for tuners to do target boost then taper down

    Infact its not that often a tuner can maintain clean target throughout a full run and some of the best in the country adopt this method as was our goal along the way as a steady load scale helps dial in timing with little fluctuation starting to make sense hey

    Same with afr as its all a seasaw effect !!

    Clean boost and clean afr's make for a tidy tune and inturn a quality result, butttt sometimes a sacrifice might have to happen to satisfy a different issue ( but thats another story )

    I have loads of dyno pulls logged and piks for all of our learning and chance to reflect what we were doing along the way and how we could better our methods
