  1. You say Your boost is to high after 4500 RPM. I am looking at Your boost control. And main wastegate dc% table is set to 0. Are You refering only on wastegate spring pressure? Couse now, ECU is not controling your boost. Tune Your boost map first. Anti lag. Not even suggestin this function for street car. So basically, tune the boost control first and then test the car. What RPM you are making full boost? If it is 4500 RPM. It more then enough for street car. If you boost you car sooner, it will start wobbling in every gear and driveability with that kind of a car is horrible.
  2. Hello, I have Vipec V44 ECU. There is no Knock Control. And Link G4 Knock Block is no more available which was adapter to monitor knock.. I've tuned the car on the dyno, it has no knock. Everything is fine. But when the car is on the track, I don't know if it's knocking or not. Yes, I've made iat, ect corrections, but still.. It it's very theoretical. My question is: Is it worth to buy Link Knock Light and put it into the car? That way I could see on the GoPro if it was trying to knock, or even driver will see the knock and will release the throttle to ensure no engine damage... I would like to know Your opinion is it worth to spend an extra bit of money or go all in with new ecu.. Best regards, Gytis
  3. Hello, I've reached Phormula salesman and now I am a bit confused.. This is what he told me: "The KS-4 provides a 0-5v output, in the same way as any external knock interface. If the ECU is capable of combining the 0-5v signal with the crank angle, then you may be able to do individual cylinder control. If the ECU can be configured to retard individual cylinders based on the knock value at any given moment then it should be possible to retard individual cylinders." So maybe KS4 and Vipec are friendly and configurable? Can vipec combine knock analog signal with crank angle? And how vipec makes the retard, on any value of knock?
  4. Well yes... It looks like it won't work properly with Vipec.. Adam, maybe You have some kind of devices which could work with Vipec? Or there is no more options, just to buy an i44 or i88? Maybe there is some vendors which have in stock.... hope so..
  5. Hello, I have a car which I take care of and it's a sports car, rallycross supercar. It has 2.0 cosworth engine and it can make 600 hp. Now I've tuned it for 500 hp. Because I don't have an electronic knock detection. I used a simple old school det cans, which is good, very good to listen knock, but i made a safe ignition tune, I didn't wanted to take a big risk. Now the team decided that we should take a max power from the engine and also to have a good logging option. So I'm looking for external knock amplifier for v44. Does anybody has a clue if this product could work with v44? (http://www.phormula.com/KnockMonitor-KS-4.aspx) Also, maybe someone has a wiring diagram how to wire external knock control? Would be really appreciated. PS. Adam, on the last my post You helped me with staged injection, Your knowledge helped me a lot. Thanks. Now engine is running much smoother.
  6. Hi Guys, I've managed to wire two injectors per drive in parallel, exactly the same as it was shown in the "help". Injectors are high impedance siemens deka 630cc. So, 2 Injectors on one Drive. Sequentially working. I've made everything I could. I changed setup, to Saturated. I've changed the dead times. I changed the Master fuel to suit the fuel table. But I can't start the car!! It seems like it want's to start, cranking is good, looks like it grabs the fuels but when I release a start button it stalls. Maybe someone has an answer, what did I forgot? p.s I changed injectors from low Z to High Z. Low Z was only 1 per drive. Now high Z 2 per drive.
  7. Well.. That's not a case, my intake manifold has direct injectors just before valves. And injectors are behind the throttle bodies. I need that injectors would fire for each cylinder. 1 Cylinder injectors would fire and other 3 Cylinders would be off. And etc. Because now I have sequential injection wired. If I'd like to run 8 injectors. I will just wire second injectors and make a pair on drive. That way it will fire both of them at the same time and same duty cycle. Its performance car, so poor idle doesn't bother me. Even tho, i use ALS which makes idle 2750 rpm. Thanks Simon for support
  8. Hey Simon, You say that one drive can manage two injectors each? If my firing order is 1-3-2-4. And into 1st drive i wire cylinder 1 and cylinder 2 injectors they will operate differently? Into drive 3 I wire Cylinder 3 and Cylinder 4 injectors? Same with secondary? Best would be to have a scheme...
  9. Hello, I have Vipec V44. My engine is 4 cylinders. I have 8 units of siemens deka 630cc. I would like to run staged injection on the vipec. 4 injectors would run all the time. 4 more will operate on higher load. And they will split 50/50. On higher loads injectors will operate at the same pulse. Is it possible to do that on V44? How should I wire those 8 injectors? Maybe someone has a scheme or something?
  10. Hi guys, So we manage to get 8 new injectors for the engine ( Siemens Deka 630cc ) and now we want to add second fuel pump for better flow. Here's the wiring diagram I've made, is this right or i've made a mistake? Pumps will run sequentially at the same time. Also, what current relays and fuses should I use? Thanks for support guys, Dual pump.bmp

    Injector setup

    From You perspective is better to put 8 low impedance or 8 high impedance injoectors on V44P? Question is not more about injector itself, but the ecu. Will it handle a 2 low impedance injectors on drive? Now we run Siemens Deka 870 cc. And the peak is 2.2 Amps, hold is 0.55 amp. If I double it, peak is huge 4.4. It could burn the drive, or not? What the highest current it can hold.. Im little confused and just trying to understand the better way of improvement.

    Injector setup

    Scott, Could You recommend me what type of injectors to buy and maybe brand of it? 8 injectors for 4 cylinders, Cosworth YB engine, running on RON102 elf racing fuel and be capable to reach 520hp+?

    Injector setup

    Hmm.. Thats easy to do. And if I put Bosch EV14 (60lb, 12,5Ohms) 2x injectors per drive? Whats then? I am very thankful that You are supporting me..

    Injector setup

    Hello, Well sport season ended, modifications starts. If I were using these Siemens injectors, 4x injectors for 4 cylinders. And If now, I'd like to put four more of them side by side. So it be, 2x injector per cylinder. Siemens 3105 is low impedance and its peak and hold type. Should I divide the currents of Peak and Hold by 2? What do You mean to adjust currents? Adjust by what? Maybe there is some formulas or something? Thank You, for response Injector.bmp
