failure:

comments: EWG needs more spring (0.3 bar) so has some lazy spool (140kw @ 4000rpm) and drops 2.5psi from 5500 to 6800 rpm, so gate is blowing open. 

Should update this, went back for some fine tuning to the e85 tune, and turned boost upto 23psi. Made an extra 30 rwkw.

Is the boost control issue sorted?  Still looks a little on the lazier size

Yeah, its holding boost to redline now. Yep still lazy, probably lazier now after the retune, but i guess thats the joys of journal bearing turbos. Not unpleasant to drive though. Still chasing an electrical issue (TPS or TPS voltage, something to do with Nistune, dunno) where the car goes into a limp mode of some description if it bounces the limiter so haven't been able to do a proper run down the 1/4 yet (only managed a 13.5 @ 112mph, 2.8 60ft)

Need to set the rev limit counter value to 255 and also set the map sensor counter to 255 to stop it going into limp mode :)

 

I will give this a go.. Thank you good sir

    • What's wrong with the OEM filter. They do the job perfectly. As to your actual problems. Stop driving the. Take it to a mechanic. If you actually do have a fuel delivery limitation and you are putting it under load, you could be killing it.
    • Enjoy Japan!  Need someone to carry your bags........??
    • I don't know the answer, but my uneducated guess is this will not work (or, not as you want it to). I would wire the SLD into VSS1, I bet that is what the limiter uses However, I also bet the ECU compares VSS1 and VSS2 and throws and error if they are different. Best suggestion I can make is wire it into VSS1 and see how you go, I guess the error will only appear above 180 when then SLD is active. If it appears at lower speeds put a switch into the SLD earth (or power supply) and only turn it on when you need to go over 180.
    • Hi all, So, looking to do some general maintenance on the car, as it has developed a some slight (related?) problems; Three problems that I think are related. 1999 R34 GTR RB26 - engine will sometimes cut out while left on idle, but will keep going if I keep throttle input. Usually after having driven a while. Its random, somedays wont happen at all, others will happen once or twice in a half hour drive. - Second issue is that while driving, the car will sometimes not be able to get past 3k rpm, no matter how much throttle input I apply. - Lastly, car will sometimes be real laggy climbing through rpm, but if I apply lots of throttle problem will seem to clear and go back to normal. All issues come and go, again somedays no sign of any problem, other days will just be stuttering around for ages.   I think it might be either the fuel system, or maybe the AFM?   Either way, I am going to clean the AFMs, and replace the fuel filter, use some injector cleaner in the next few fill ups, and might look at doing the fuel pump aswell.   Question I have, is filter such as; https://www.efisolutions.com.au/pro-fuel-filter-30-micron-an8-orb-black Fine to replace the normal filter? Their product page says as a prefilter only and not as the main EFI filter, so I'm guessing I would still need the stock one? Can I get an aftermarket one that has AN8 fittings to replace the OEM one? Or is the OEM one just something you have to live with?
    • I say this and there’s a Nistune r34 GTT MT ECU for sale on eBay.de but I need to figure out compatibility between the AT harness and MT ECU - TCS considered. I figure this HKS SLD is a quick bandaid anyhow.
