another thing I've noticed running e85 for dd all last week was how much smoother the car feels on rev up, even gear changes feel smoother

also significantly less carbon output in my exhaust tips

I was heading out at night doing quite a few tests and logs so I can't comment on typical dd fuel consumption yet

ive been running E85 for a good month+ now. Im getting around 290-320 kms to a full tank inner city driving. Thats around 50km less than i was getting with 98ron. However, the smoother running, lack of carbon build up and midrange pull far outweighs the extra mileage

added some HKS SSQV 4 bovs using the HKS R34 flanges so i could mount to my oem intercooler piping

may just be a placebo but im pretty sure the responsiveness getting on/off throttle quickly at mid boost is better and a touch smoother

recirc'd they sound great (together with the TS intake and larger TS turbo inlet pipes), not ott loud, just enough to know they're there - they fluter at low boost and dump at high boost

also ordered one of these + a gm flex fuel sensor to monitor my ethanol content - and have 2x 20L drums of E100 (from racefuels) just in case the local caltex brew dips in the low 70s

Car looks stunning! Love the boot. What LSP you got on there?

Caltex is pretty much bang on E70 last few months. Only saw a bit of a dip in the middle of winter (mid 60's) prob for a little cold start help, but since then, E70.

Can the Cobb take the digital signal from the Gm sensor to alter the tune on the fly? Not sure if you know, but Trent @ Chequered set my car up with the GM sensor and a Link G4 to be completely flex-fuel capable, ie, tune will alter real time depending on the content/mixture of 98/E85. Safer and optimum performance.

Thanks for the feedback guys

Gohan no the Cobb can't adapt on the fly just yet

But I can monitor the ethanol percentage with my Zeitronix + gm fuel sensor... and I'm already hard wired for when/if Cobb release flex mapping

I do have those drums of e100 just in case I get a bad batch of e85

I've been running the caltex e85 with no issues at all, a testament to the safety margin Martin built into my map

The latest map Martin sent me feels like the boost comes on harder at lower revs, and Im getting all 4 wheels spinning through the midrange in 3rd now lol

The easy datalogging with the Cobb has proved invaluable in continually tweaking my tune. I email the file to Martin and he emails me back a revised map. 5 mins later it's uploaded on the ecu

Re LSP, its opti-coat + prima amigo + naviwax dark - I'm a hobbiest detailer and among the 30 odd waxes I have (collect) naviwax is my numero uno pick at any price point

Hey man, looks killa. I heard about this opti-coat stuff and seen some vids on YouTube. Where do you get it from, along with the naviwax?

the opticoat I had applied by a pro, immaculate reflections. You can buy it from zas locally, but it is quite finicky to diy

if you want to diy a coating, I'd rec you go with cquartz

you can buy naviwax off eBay uk now

    • Have you done the Ignition Sync Wizard in the AEM software?
    • Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...
    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
