E10/100 On A Pulp98 Tune - Any Issues?

You need a retune to make use.

Just changing fuel will not realise the full benefits.

There is extra timing and fuel mappings that need changes to see the gains that are to be had.

That's what I thought, but is there any danger?

ie due to the ethanol content not flowing enough fuel on the PULP98 tune? Or is 10% ethanol not enough to drastically change the flow requirements?

Should be ok, I tried it a while back for its higher octane but I found little difference in knock protection between that and BP98. If you want benefits re-tune for E85, more pumps should become available very soon.

No worries. Yeah i plan on getting a netbook to plug into the Haltech and tuning a map for E85 so i can switch between the two as need arises... Just dropped $10k+ on the car though so perhaps i'll leave it a while.. ;)

Well not overtly major other than the "why?" ;)

Just use as is until you are tuned for it.

I just happened to be at the airport and needed some petty. United had E10/100 and as i'm not sure what their 98 is like i thought i'd chuck half a tank in.

Just wanted to make sure it wasn't going to break anything :blink:

i use E10/100 ron and i certainly rate it. its about 1.20 a L most days and ive tuned my car to suit the fuel. awesome torque gains from few degrees extra timing.

Would tuning for it be that easy - just bung in another couple degrees and run it up on the dyno to make sure it's still not near detonation?

after all the dollars you spent on a custom tune I would just run 98. I would only run the E10/100 ron fuel if you took it back for a quick retune.

I tried the E10/100 ron fuel a while ago and I got 5L/100km worse fuel economy for no gain in power (because I didnt get a tune). So I quickly changed back to 98.

Just wait for E85 and get a custom tune done then.

      33 GTR Broken front wheel knuckle

      By R32 TT · Posted

      Just had this happen to me too.  R32 GTR.   Also broke "just before going out onto the track" - someone up there is looking out for us... Very scary since I was about to do a narrow street course with zero run-off and curbs everywhere. Many people on here upgrading to billet uprights and R35 bearings?   Or buying new OEM knuckles?  I am not keen to replace with another s/h 30 year old fatigued part.

      Coolant leak?

      By joshuaho96 · Posted

      Top off with distilled water and see what happens. If you keep losing coolant then you know to start looking.

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
