any good link tuners in sydney??

im beginning to think e85 and its availability issues will be the end of the good old pfc

I havent read the whole thread but send it to Unigroup Engineering in Girraween. Yavuz tuned our link G4 and was very impresed with it. Add to that the fact he really knows his shit :D I have been ising them for years and woldnt take my car to anyone else. And i use to work for another big name GTR workshop in Sydney

I am actually going to speak to him about using this Ethanol sensor in our car this weekend as Sydney only has a handfull iof servos with E anything and to do away with the laptop on the back seat would be awesome :D

Do 9's what combination are you running? Low mount twins??

I couldnt tell you how it compares as i havent seen those turbo's on a similar engine. The head has a fair bit of port work done. I know we are quite happy with the response we have. 22psi at a little over 4000rpm is pretty decent.

Was hoping to have a cracck at 140mph this weekend but the drag days been canned :(

T78's are one of my favourite rb26 turbo's... when set up right they really work nice.

hey you guys so i have some questions.

I am running a 2.7 RB with an HKS F-Con V-pro with 1000cc HKS injectors. We want to run E85 with the Flex Fuel setup since its impossible almost to get race fuel here in California (to many forms.)

So with that in mind we are thinking about running 1600cc Bosch Injectors. Not sure if the HKS unit can control them at idle??? anyone have any luck.

I know a lot of you will tell me to use ID2000cc but honestly thats about 1200USD for a set and I just cant justify that after already spending that much on the 1000cc HKS injectors.

So a couple of questions:

1. Whats the most amount of boost you can use on e85?

2. Why do you use the GMC Flex Fuel sensor over the Ford Sensor as its seems to be 5 times the price.

3. Can you run E85 with Methanol and what are the benefits.

4. Instead of replacing the HKS 1000cc injectors could I just add 2 additional injectors to the intake manifold?

Thanks you guys. This thread is very informative.

What's your duty cycle % thingy with the 1000cc's at the moment? i'd be thinking you might not need bigger. And more importantly, what turbos?

1) how long's a piece of string? i would say it rests entirely on your current setup

2) link to Ford sensor please, it might be a lot more economical for people then if it's cheaper. I wasn't aware of any other options at the time other than getting a $50 s/hand one from a wrecker.... which i didn't want to take the chance.

3) No idea

4) How do you know you need to replace the 1000cc ones?

in other news, i have been mixing and matching a bit around town but where the Flex setup came in ultra handy recently is on the drive back from Shepparton. Motorsport even out there, car was on E-flex on the way out, took a couple jerry cans for the event (and to top up after the drive out), running a bit low on fuel on the way back though, no e-flex left in cans, no worries, pull into the BP at Wallan, throw in some 98, smooth as you like spirited entry to free-way on exit and cruise home, without a hitch :) Easy, simple and works flawlessly :)

I highly recommend :D

Powertune can do it too

I'm going to go through them

That link seems to show an aftermarket sensor...

Quote: How does it work?

Simply put, our sensor duplicates the signal that the OEM sensor produces. Your engine control module sees the signal it expects and it clears the engine failure codes. Our Flex Fuel Smart Sensor is designed to use with Regular Unleaded Gasoline which contains up to 15% Ethanol. We do not recommend installing our Flex Fuel Sensor and continuing to use E85.

Not sure what they mean though.

Didn't read down as far as you did - looks like a fake - definitely no use for flexy system :(

I'll ask him aswel what sensors he would go for and which sensors the ECU supplier likes.

Agreed saving $50 isn't worth it, but it doesn't hurt to ask and see what they have to say, who knows the ecu guys may have one

  • Like 1

Its not actually a flex sensor by the looks its just a signal generator that tells the ecu its constantly running regular unleaded... The signal may be tweaked slightly to compensate for the 15% E mentioned.. Id assume the ecu would go into limp mode when the factory sensor shits itself to save people money this is an option especially if your not running high % ethanol mixes..

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
