ahhhh lol i just looked again and i saw that there is more, what do they do/what r they for?do they just provide power to the injectors? sorry im new to liner engines and i didnt even know were the injectors were, now i now lol. reason i ask is cos they vibrate/tick wen the engine is running. well i think its them neway

Yep they probably tick when the engine is running, most if not all injectors do. Nothing to be concerned about, they all tick.

The ticking means there working, well its more or less the injector opening and closing, thats the ticking. There spring loaded inside, and its the plunger inside of the injector that moved up and down to allow fuel into the cylinder, I think thats where the ticking occurs!

Plunder opens and closes according to the signals from the ECU.

The plugs to the injectors do supply power to the injectors as well as signals from the ECU about how much fuel to spray in to the cylinder, when and in what order. Those signals are made up from various other things such as airflow (AFM or MAP), throttle position (TPS), coolant temperature sensor, voltage sensor, engine speed sensor etc, etc..

Sensors do all the reading (sensing), and the ECU does the calibrating. I think thats the correct wording!

thnks man, like i said, im not used to the tecnicals of these hi-tech engines (well high tech to what im used2 lol)

that helps at least i no it aint serious. so im guessing if u undo the screws wher it plugs in2u cn take out the injectors and thats how u put in aftermarket injectors (say 550cc-800cc injectors?)

Basically yeah!

Will have to get the car tuned though, so after market ECU, either stand alone or fuel only, or a REMAP of the standard ECU which is starting to get phased in with the R33s.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
