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

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...

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?

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

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.

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+?

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..

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

Thx Simon, This should also works yes? http://www.kasensors.com/us/products/sensor-switch

Hello guys, I have new gear cut sensor, now I need to know how to wire it and tune properly. Im thinking of Digital input and select Gear Cut or GP input for tune.. It will be installed on sequential car gearbox.

Hello Tuners, I run 4 injectors on my 4 cylinder engine. I have intake manifold which can have 2 injectors per one cylinder. So my question is. Can I wire 2 injectors (for example 440cc x 2) in to one injector input?

Hello guys, We have a probem on our racing car. We use Tibuc intake manifold which has 4 throttles and responsystem valves. Which is used for anti lag. But when i log on my pc and ecu. I dont see ISC sensor connected to Aux outputs. So my question is how to control idle speed, through respons valve ( the wireing is down bellow ) or through main throttler body? Only this problem left on car... The whole ECU wireing was made by other guys, so we cant figure it out is it in ecu or not...

Hey Guys, We run GTX35 on Cosworth YB engine, finally we got inconel exhaust system. And now we need to install all sensors. Maybe You know, how far innovate sensor should stand after turbocharger? And also EGT sensor how far should it be? Thank You a lot, Gytis

Understood. Tommorow I will contact dyno garage. I will post how it went there.

Hey guys, So, last weekend I tuned a little bit of Fiesta. I managed to get good cold start, and now car starts pretty good, but I also got some issues too. 1. I tuned an Anti-Lag tables ( ignitionR, fuel, ignitionC ), and on the test run, on 5gear comes up limit 6000RPM and stays there.. But on my Limits table are 8000RPM the cross. So why when I turn on anti-lag rpm limit gets 6000? 2. How to get more boost on open loop? Can u take a look on wastegate trim? While anti lag is running MGP stays really low, but it should be more.. ( I think ) 3. Launch control, I didn't get the boost I wanted on start line, the boost I get is 0,4 bar of MGP. Target is 1,4 - 1,6 bar. 4. Can u set a primary wastegate trims for me to start with? Boost and anti-lag we want is only on low speed. Rallycross is a short track racing with lots of corners.. So when the car stops till the corner, we need boost to make instant speed when driver hits thorttle. Thats why anti-lag is setted up on from 0 to 30% of TPS and till the Rev Limit 8000. I attached the PCL and Log of last run.. If you can take a look.. Also I add fuel on anti lag and Turbo wasn't that red.It reduced the EGT. Sorry for bad english and mistakes.. You see it's not my main language but Im trying Regards and big Thanks, Gytis LognPCL.rar

Hey Dave, Im looking for knock sensor to buy? And I found this one for really good price. It is good one, what do You think? Regards, Gytis

hey Dave, Engine: Cosworth YB 2.0 litres, 16v Tibuc intake manifold 10.5 rate of cylinder compression Garrett GT3582R with 45mm restrictor. Cat cams (camshafts) SIEMENS DEKA 3105 (850cc * 4 units) Gearbox: 6 gears, sequential.

Hey Dave, Thanks for your help. I have one more question, if u can answer for me :geek: So, I am looking at ignition table and i dont like it. I want to set it up by myself. But I have question, How to set ignition table? I dont have a dyno but i can tune it on the air port landing road. This is the ignition table which i found in ecu. I managed the QuickTune for fuel table and I will do it, but first i need to know how to set ignition. By the way, ECT gets really fast to 80 C. There is an 18litres of cooling water, big radiator in the back and 2 big fans. We use external bosch water pump, which pumps 200 l/min. And I dont know why. So: 1) How to set up Ignition table, what devices I need to get....? 2) Why ECT reaches very fast 80 C.? I think this is the last of my questions and I will try to tune the car a bit :>

And also, what should i have to do, to make the engine starting smoother... Couse now, when the engine is cold and Im trying to fire it up, it just cranking and after 3-4 secs fires up and spits big black smoke.... I know that u can't tell me the 100% answer of this problem... But just tell me all your opinion... I very grateful that u r helping me guys... Thanks a lot.. Gytis

Hey ya, I thought the same way as you.. What do u think about ALS setup? Is it right? Because there is the same stats.. I have a friends which is a tuner, I will talk with him. But also I need your opinion too. And also, I will try to correct some of tables and practice on track. Step by step, little ones. Don't worry Dave for late answers.. Im student now, I can configure the car ecu on weekends only. Regards, Gytis

Got it. This is the last tuner work. Turbo gets really hot, IAT I get is 50-55 C, and the EGT is probably 800-900 C.. What do u think what do I need to change? Im very confused why the tuner made decreasing fuel table? I want to understand things I which i cant figure it out. Also, I need ALS only at low RPM, like from 1000 to 3000. And yes, software is 4.10. Also I upload the Launch-Control setup. Im very happy that u hellping me!!

Hey Vi-PEC team and tuners, I recently have been tuning our fiesta. Everything looks quiet good, but when I turn on antilag, turbo temeprature gets really high. Should I add extra fuel to cool down gasses? Other thing, how to download latest log file and correct fuel with auto-correct function? Because now, when i try to download log file to my pc, i see all 10 slots are filled up and newest one isnt there. So: 1. Should I add more fuel while ALS to reduce exhaust temperature? 2. How to see latest log file and download it? 3. How to set up Mixture map for latest log file? Because I cant figure out auto correction, it doesn't correct anything, it just turn blue and on fuel table shows me where the spot is and I manually change the numbers. And how to download latest one, because now im correcting bloody hell something... I read manual of it yesterday. But on mixture map properties I cant select fuel table.. well, im adding my log and pcl. If u can, take a look. Thx people for your help, Im trying to be a better tuner :roll: Gytis vaziavimas1.pcl

Hello engineers, I have V44 on my Ford Fiesta RX. ( Deka 850cc, GTX35(45mm restrictor), 102octane fuel, 10.5 cylinder compression) I cant't figure out how to set launch control and anti-lag. This is PCL. I hope You will help me. Regards, Gytis FiestaRX2014.pcl
