I Finally got around to doing some logs and changing some settings with unisettings.
i finished off my last tank of meth with a 20% mix and it really didnt feel good so i went the other way.... at 50% the car felt so much more eager so the butt dyno won for these logs.....
the annoying thing is i think my MAF has gone, ive never seen it run with figures that low before. recently they have been up to 217g/s so something must be wrong?
i think i might go back and put the fueling back to standard as its not making a huge difference....also, does the boost seem a littlelow for B9... isnt that normally over 1.5bar ish?
i thought id log block 66 for some fun.... there was loads of standing water tonight so it might not be the best test but still here are the runs

Hmmm looking at your logs mate it doesn't look with regards to your MAF. Not that its an exact science but I would say looking at the readings of your MAF its coming out that its runnning around 240ish bhp which clearly isnt right.
Is it running like dog with 3 legs at the mo?
Oh and 114mph........naughty boy!

ta matey.. regarding meth... it last quite a while but its dependent on the strength. i probably use about 5ltrs for every 60ltrs of fuel....thats a guess.

i was suspecting something was wrong with it Ed as on the way to AMD the other week someone pointed out that i had forgotten to plug my MAF back in and i hadnt noticed the difference...... this just sort of confirms it for me, it flowed more as a standard car
......that said though, it doesnt feel slow at the minute.lucky i have the hangers near me....i would never do those speeds on a public road
.
IIRC mate the MAP sensor can only read upto a max of 2480. What is boost reading on your boost gauge?
LOL of course.... I forgot about that, it was late last night
Boost gauge is Reading about right at just over 1.5bar
Thanks damien

No probs mate
(Quickly) Boost is requested, then actual. (Map sensor =2540 max reading)
You'll only get advantage from a 50% meth mix if the engine is burning it and your timing needs to be advanced quite a bit to do so. Your timing doesn't look advanced to me.
It also looks to be running a bit lean. Sorry I haven't come back earlier, I'll have a good look tonight.

Thanks Dave.... are you saying im not even requesting the right boost?
The fueling isn't too bad is it? I will add some later (it's not my daily driver) but it didn't seem dangerously lean.
The Maf can't be helping.. I need to get this sorted. how much of a difference do you think this is making?
i do underdstand what you are saying about the 50% mix, it just feels so much better this way. i tried pushing the timing more but had the same problem as you.... i wasnt seeing a difference in fueling and was getting a load of CF's. i spent ages last night playing and in the end thought id give the car a rest. this is going to sound like a stupid question but what is the real difference, if im not burning all of it, wont i just be using it to cool the charge like i would if i ran ran more water (although a weaker mix is obviously cheaper)

What sort of power figs are you running now mate, any idea? (Apologies if ive missed it earlier in thread..)

Hey probee loving your car! Can I ask where did you get your cold intake feeds for the induction kit. Cheers.
Think he's running 283bhp as per his sig....
you had to do it didnt you....if i was being honest i would change that since it didnt run that on the last RR....
I don't quite understand why you've taken some fuelling out. A failing Maf could be causing it to run a tad lean.
Before you write the Maf off, I'd redo the runs with the wmi switched off, just as a check.
When I took mine to a JBS RR day with the wmi newly fitted, midway through my development, I thought it felt fantastic running 50/50 wmi. However on the rollers we quickly proved it was running 30bhp less with 50/50 wmi on than with the system turned off altogether............
The only way you get to burn the methanol is by advancing the timing. When you're ready, I'll post you a ref to some calcs on this.
You'll cool the charge injecting just 0/100 = water. A 25/75 mix will give you great intake temps - any more the this and you won't see your intake temps dropping - try logging 032 to see. Unless you can burn the extra meth, it's probably just quenching the combustion.
