same weather but when engine is cold, high boost when warm , it can't go beyond 7-8psi

 

look at these scum bag , there is a reason worrying about my baby 

 

Where's the abuse? Road testing with very conservative driving.

friend of mine had its car totaled by a dealer here who was meant to service it .

 

a 19 years old took it out and trashed it who was a technician

 

a question re link ecu, I installed new turbo and wanted to take the inlet manifold out to paint it.

whilst doing it, I realised how much of a pain it can be to even change the injectors so I have decided to get the 630cc injectors and install it and take it to tuner.

 

my question is, if i simply plug the g4 into the car, can i change the injector size and then the base map will inject correct amount of fuel or no ?

spoke to Link tech and was told I could change the injector opening time to half which would allow the engine to run on the 630cc injectors and can slowly drive it to tuner. thoughts?

How do you plan on doing that? Is there an Injector open time table?

A proper tune will never take ~3-4 hours unless your tuner already has a canned map, your car is perfect, and they just need to verify that everything is running properly + maybe small tweaks here and there. It will take a few days to do it right even though Link or whatever ECU manufacturer of choice is providing the base map which shouldn't be too far off in the first place.

OEMs take months of engineering time to do the factory calibration. It's a full time job. Even then sometimes they run out of time and it's too late to get another calibration emissions certified and you end up with a factory tune that breaks engines. Subaru has done this before. With a turbo engine especially the dyno cannot do everything for you, some road testing is needed to tune for real-world IATs.

Engine calibration is not for kids. If you don't trust your tuner to not crash/abuse your car they have no business doing an ECU calibration.

Some logging is needed to diagnose why your car is running wrong on the base map, if you can screenshot a trace of the behavior people can probably help.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      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.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      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)?
