After countless attempts at getting my R33 S2 Gtst to make good power, I am finally there and happy.

It is making 360rwhp and drives like a dream. Prior to this it was making 305rwhp with similar mods. The real difference - the tune (tuner to be exact). Sometimes switching tuners makes all the difference....

Dont want to rain on your parade as this is a huge jump just on tune but was it done on the same dyno in same conditions as this might be a reason for some gain which is not really there?

I am sure that if the car drives in such a way that he has been excited by it, the numbers probably are reflected in driving experience :P

agreed there would be gains just not close to 20% gain... also worried about the placibo effect you know it must be quicker cause the dyno said so...

i am not trying to be rude i just prefer stats that are real in terms of this... example is my car is identical to my brothers as in we are 100% neck and neck every drag/race but he has 28hp more then me... this is not my skill but a different dyno different day.

some tuners are lazy, and just pull a big chuck off the stock timing and smooth out the A/F ratio, sometimes not even touching the Injection map, they just scale the Air Flow Meter which is purely lazy.

I've borrowed a datalogit and fixed parts of my map up, and added more timing after peak torque (using a combination of old dyno graphs).

yeah there is a certain tuner/workshop in Sydney who tunes just like this...it was a mates car so i re-tuned it properly and made heaps of gains in power and response as well as fuel economy...and i cannot tune for sh1t but know enough to get things looking reasonable. Made 450AWKW the next day at Autosalon and won him a trophy...yay :D

this workshop charges big $$ too...pretty piss poor.

      There's more than one way to skin that cat, and most of the sump Maatouks have done will be GTR sumps. They are HUGE in GTR drag racing here.

      Yeah...I always start at the shift solenoids, because there's only a few reasons these will spook into limp mode, and bad shift solenoids is one ~ the other can be the shift control module (if you have steering wheel shift buttons)...it's easier to eliminate the solenoids first.

      Never ending fuel pump drama

      By cabramatta · Posted

      Might piggy back off this thread since there's been a good discussion about PWM.   I purchased a Walbro 460 F90000267 and have been looking into PWM to understand it. It was purchased more of a future proof as my original OEM fuel pump died (r33 below 200kw) and figured I'd just upgrade it to this. That's when it hit me that a pump this big can cause more dramas with such high amperage draw and heating of the fuel pump being on 100% all the time in such a mild setup.   I have a Nexus R3 and slowly collecting power mods but I was looking into the PWM feature on the NSP software:   Then looking at the graph from the fuel pump:     Am I safe to assume reducing duty cycle to 50% for example would make the pump run like a 230/lph ? Where does the PWM come in all of this ?   I've gone down the rabbit hole of PWM fuel pumps and it seems there are many differing opinions on how to go about it 😅

      Thank you, this will keep me busy for a bit.  I will update progression.

      That specific one would be an exchange part, meaning I'd have to send mine to them. Plus it looks like a non AWD sump, which won't work for me. There is one or two shops in my country that I can ask to do a sump extension job and it'd most likely end up being cheaper than sending mine to AUS or NZ and getting one back, and quicker too.
