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

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

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 :(

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..

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.

      Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
