yer but no one inspects every single batch on a regular basis. bp98 is considered the best here but even so i've had one batch that needed 7 degrees of timing taken out across the board under load to stop it pinging badly, unless every batch before that was 105+ theres no way that tank was 98. not a once off either, its happened a few times, just not always that bad.

Marko, I hate to be picky, but I will... you also did the same thing in your opening post. :D. Must be an inherent anomaly with the Blackberry. I'd get it checked. :nyaanyaa:

PS, withheld would be a better word :D

PSS, I am keen to try E85 when I finally get my car finished.

u must be a journalist haha, u ballbreaker u :)

The only logic in not running E85 Marko is the range. Engine safety from the point of view of detonation/knock is better on E70/85, and the minor variance in AFR is minor. You may well be more likely to detonate your engine on a bad batch of 98. Your tuner is being left behind....

Does the legal requirement for 98 dictate at the bowser though? It'd be near impossible to guarantee that after all the contamination between refinery and the pump. All it would take is that fuel sitting for long enough in the servo tanks to drop in octane.

Yeah at the bowser, companies cannot market it as 98 if it's not.

If they get found out there are ramifications. But realistically it's not that well policed... Can't go around checking up on the people that make the Gov't loads of money now can we?

The joy of typing on blackberry with a mini screen, I left out "not to be"

Stevo - that's the other reason e85 is not for me as I also like to take long drives and will become stranded on e85

You can have 2 fuel maps with the Vipec, use one of the digital inputs with a switch to change between an e85 and pump fuel tune.

i was unaware of that - i still have a lot to learn about the vipec capabilities (still thinking of my dinosaur pfc)

So, changed your mind yet, Marko?

Atm I'm smashed, drinking all day and had a 15kg pig on the spit so my mind is clear...I'll stick with 98 pump and my 700cc injectors and leave it with my tuner (crd). So how my pierburg fuel pump runs as they support 500awkw without a problem

I was getting prices of $500 just for the ethanol content sensor a while back, have the prices come down?

Or you could save yourself the hassle and buy the V500 Ecu instead. It's pretty much the same price as the vipec/haltech/Autronic etc but does so much more. That's the beauty of running multi-controllers.

Then you don't need the E85 sensor, you just need a wideband o2 which are approx $125-$150

Could you tell more about this ecu and how it works with the wideband please?

This was already explained by Hyped6 about a page back. You use lambda as a reference input into the ecu and have it add fuel if it sees leaner mixtures above a certain rpm/boost level etc.

You can put tables over tables over tables to achieve virtually any result you can think of

what if the wideband packs it in?

What if the E85 sensor packs it in?

What if a massive comet comes from outer space and crashes into earth?

As long as you change the sensor out every 100,000k or 50k if you are paranoid, then you will be fine. You could also argue about the e85 sensor and changing it out, but at $500 a pop?, hmm.

What sort of switch can you use for this?

I'm running an Emanage Ultimate setup with E85 and LPG tunes. Right now I need to flick the dip switches each time I switch fuel.

I'd love to run a switch to the driver's side so I can switch tune on the fly. The Emanage has two "Options" input...

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
