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

    • HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.
    • The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.
    • Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?
    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
