  1. Ok, then the adder table should be the right one for that. Thank you!
  2. Ok, if I unterstood you correctly: It is not necessary to insert the whole flow dataset somewhere in PcLink, but only the correction to get a linear line below 2.2 ms?
  3. Ok mates, finally I solved the riddle with the help of the injector testing function. The solution was just as simple as plugging in the connector of the injector harness...lol Now the engine is running...not very well, but i runs. Thank's for your help! So here's my next question for you: Deatschwerks provides the following data sheet: https://www.deatschwerks.com/sites/www.deatschwerks.com/files/DATA/injectordata/21S-XX-0600-XX%20Injector%20Characterization%20Summary.pdf I already adjusted the dead time table in PcLink. But where do i put the values from the "Pulsed Flow Data"-table of the data sheet? Is that the right data for the "injector short pulse width adder table"?
  4. I've done some checks yesterday. Spark test was successfull but the spark plug seem to stay dry. Fuelpump is working and there is fuel in the fuelrail and pressure on the fuellines. So I think the injectors are not getting fired in the correct way. Deatschwerks say that they are p&p for the gt-t, I'll check if that information is correct. Does anyone have more information about that? I used 21S-05-0600-6. When I disable the iat in PcLink the ecu sets a permanent temperature of 21°C.
  5. The main question is in my last sentence. I'd like to be sure that it is not a problem caused by wrong parameters in the base map or my config.
  6. Hi, yesterday I tried to start my GT-T the first time after upgrading to GTX3076 and Link G4+. Well, it failed. What has been modified? Link G4+ GTX3076 int. wastegate Link 3 bar map Tomei headgasket Deatschwerks 600 cc injectors Deatschwerks DW300 Fuelpump Blitz FMIC 3" catback + 3" downpipe + custom turbo elbow Oil gallery restrictor GFB Mach 2 blowoff What was not done, but will come in the near future? Fuel pump rewire to replace the fpcm Link IAT sensor (not wired in) Tomei fuel pressure regulator wastegate actuator (mounting plate missing) boost soleniod not installed because ot the missing wastegate actuator wideband (oem narrowband installed) Modifications to the ECU: R34 GT-T base map stored to ecu configured for link map sensor calibration of the map sensor calibration of the tps deactivated temp3 input (fuel temp - was enabled in base config and causing errorcode) deactivated the iat because of not being installed yet When I turn the key the fuel pump and injectors get highlighted in green, so I think that the ecu activates them. The starter cranks the engine but with no sign of firing it up. Could it be a problem that the iat is diasbled? should i reduce the duty cycle of the injectors? Is there any further config needed that i could check before searching for issues (ignition spark/fuel/etc)?
  7. Okay, then I'll try to be more brutal.
  8. I tried to remove the turbo studs from my OEM gt-t exhaust manifold because I need longer ones. I've put some WD40 on over night an screwed two nuts on them but could not manage to remove the studs. Is there any special method to remove them from the manifold?
  9. How about the celarance between pistons an valves? Is it a problem, when I reduce the hight of the cylinder head on a neo engine with variable valve timing?
  10. By the way, what do you think about applying permatex spay gasket to the tomei gasket before assembly? Does it help to get a better sealing, or is it just wasted money?
  11. Thank you all for the replies. This forum is much better than the german equivalent. ARP studs are already in my garage waiting for me to screw them into the block. I think I'll go for the tomei gasket because of the small extra cost but higher (presumed) reliability compared to the oem gasket. Will the higher compression ratio be an issue when mapping the link ecu because of the risk of knocking? Keeping in mind that the stock knocksensors will stay in the block.
  12. I've clculated the compression ratio value for the 1.2 mm including the 0.16 mm of material that the machine shop removed from the head. When I use the 1.2 mm gasket it will be the same as 1.04 mm gasket with the cylinder head before machining it.
  13. The Tomei compression rate calculator says that the oem gasket thckness is 1.1 mm and the compression is 8.97. With the 1.2 mm gasket the compression rate would be 9.03 and with the 1.5 mm it would be 8.76.
  14. Ok, thnks for the info. Is this the correct one? https://www.tj-partshop.com/products/13009-Tomei_Headgasket_Zylinderkopfdichtung_Nissan_RB25DET It is available with 1.2 or 1.5 mm. Which thickness would be the right choice?
  15. Hi guys, i'm going to get off my stock turbo an put on a Garrett GTX3076. Other mods like FMIC, 600 cc injectors, link g4+, DW fuelpump etc. will be or were already added. So I took the head off and got it machined to have an even surface. I've cleaned the block with a razorblade to get off the rest of the oem headgasket. The machine shop took off 0.16 mm from the head to get an even surface. The oem gasket thickness is 1.2 mm as I've read, so if I add the 0.16 mm the replacement has to be at least 1.36 mm. Correct? As I am from Germany, i've searched for a metal headgasket in the local online shops but just found 1.2 or 1.5 mm but no 1.4 or 1.3. So which thickness would you recommend? Or would the oem Nissan gasket be good enough for my setup, keeping in mind that the block was only cleaned by hand?
