    The defaults of start = 10 and length = 50 will work well with almost all common road car engines.

    There is no real simple end-user procedure to check this apart from making the engine knock and check the knock system detects it.

    Ok Adam

    Thanks

    Hello Guys,

    What is the correct knock window for 4g63 evo 8 engine with wideband bosch knock sensor?

    There is a procedure or calculation for choose right window?

     

    Thanks

     

  7. Knock sensor location

    Hello guys...

    I have an Evo8 with G4+ Thunder...wideband knock sensor in stock knock sensor location (engine block...inlet side...near 3-2 cyl)

    I have another hole in the same location but exhaust side...i want use this hole for attach another wideband knock sensor with KnockLink (or Knock Ears)...

    Can use this hole or exhaust side has much more interference/noise then inlet side ?

     

    Thanks

    Ok Adam...i cant use now knock headphones .

    Before link i used haltech with same engine configuration and the engine no knocking with same ign table...with 100oct fuel pump gas

    I Will test after fuel system problem will be solved.

    I think what has confused you is Richard has misquoted the formula above.  Differential fuel pressure is the pressure difference across the injector.  You have rail pressure on one end of the injector and manifold pressure on the other end.  

    So, the correct calculation is;  Differential Fuel pressure = Rail pressure - Manifold Gauge Pressure (MGP).

    In general your diff fuel pressure control isnt great but if we ignore that big dip at 6700 it is probably acceptable since you have set the ECU to compensate for it.  However that big sudden dip at 6700 suggests some part of the fuel system is failing.  Either the regulator is getting stuck open, the pump is seizing/sucking air/cavitating or there is an intermittent bad electrical connection.  I dont believe it would be an injector sticking as they are already at 100%DC before that dip.  Of course you need bigger injectors or more pressure to get that DC down into a safe range but that is secondary to the mechanical problem you have.

    Thanks Adam,

    Thanks for explanation.

    Now i Will investigate about fuel system problem.

    Can you have some advice about the knock question?

    Thanks

    Ok cj...i have full blown fuel pump hanger in my evo 8..fuel lines new (an10 /an6) and fuelab pressure regulator (fp sensor Is in regulator)...its all ready for IDs 1300x.

    I dont have any 1 way valve in my fuel circuit.

    Unfortunately i have a 1.2bar wg...i cant go under that.

    In my log mgp = -44 kPa , fuel p =310kpa , differential = 355 kPa...this is wrong...seems that the ecu add 44 to 310...but 44 is negative...not positive...the calc is wrong!!

    I dont understand how differential pressure is calculated..

    At idle and at 0 mgp the fuel pressure is around 290-300kpa..

    At 130mgp the fuel pressure is around 430kpa...

    I think fuel pressure increased proportionally with boost... right?

    Hello Guys,

    i have a evo 8 with thunder ecu, bosch wideband knock sensor, gsc s2 cams, stock evo injector

    i attached map and log.

    i have two questions:

    1) around 6700 rpm  injector duty cycle going from 97% to 128% and afr goes very lean...why?

    2) the knock level of cyl3 goes very high (i try to remove 2* but same situation)..why cyl3 is so different from others? i noticed that knock sensor is so close to cyl3...this can create that difference in knock level from cyl3 and others?

     

    thanks for support guys

  23. Weird fuel table values

    in G4+

    Posted

    Hello guys,

    i need some help.

    i tune my fuel table from 1500 to 3500 rpm and from 50 to 120kpa...values seems reasonable but when i jumped to 40kpa i need too high ve value.

    car is evo 8 with stock turbo and sstock injector...gsc s2 cams...direct spark conversion....and dbw conversion.

    i attached map and log.

     

    thanks guys
