Yeah sorry feel the 212 was logs on my car and was a spike, it was mainky around 210 (will post logs when i find them again, bloody work laptop). My point was that 210 seems way too high to me for stg 1, would expect 190ish

Like I said earlier and in other threads - I've seen 205-210 g/sec with Stage 1, but only in January/February.

Neilc posted earlier that Revo quote 190-205 for Stage 1 - that definitely sounds right for what I've seen logging my car and others over the past couple of years or so.

I take it you're assume that Stage 2 will out-flow stage 1 by some huge big margin? There's only 10-15 bhp difference in peak figures, that's only 13-20 g/sec. If a stage 1 and stage 2 car will flow roughly the same at roughly the same time of year, you'll see why a few people will says stage II is not worth the money :bleh:

In fact, both mine and ice maiden's car is out-flowing yours at the minute :bleh:

Anyway, enough of my willy waving (as large as it is) - what we should do is graph all these MAF, Requested vs Actual boost logs together to form a factual database of, erm, facts.

email me logs of 003, 115 and 020 (what else?), mods, stage 1, 2 or 3 (and choice of turbo for 3) to "cafe dot racer at ntlworld dot com" and I'll see what I can do.

I've had no emails :D

But anyway, I just wanted to post that I saw 205-209 this morning (even though it's bouncing around like a bitch - dodgy N75 I think...)

would a split in that hose meaning the maf is reading lower air flow in turn cause less fuel to be put in and me to run higher cf's as i am boost 9 timing 6 at the mo and in the 4th cf colun i see some 5's and 6's but only at about 1800rpm

Anyway i finally got off my backside and did a log. It was a bit 'finger in the air' as i couldn't remember what i had on before so stuck it on T7B7. I think i can get more out of it but it seems quite revvy at this so it might stay. Stg 2 lcr. Ignore the first few CF's, it's just cos i started the run at about 1k revs.

What I meant by posting this is that in the space of about two weeks, as the ambient temp dropped (to 3.5'C) mine's gone from mid 190's to 209.

anybody pls? Im phoning to see bout apr tuning today but i don't want to book anything if my maf is buggered?!?!? will it matter bout the apr remap if my maf is buggered, so when i get a new one it will work better with out affecting the remap?

PS how the hell do you get the maf out??? it looks like a torx security bit, but my torx security bit the hole is too small, is there a special tool or is it pot luck on torx manufaturers as tro gettting a bit that fits?

Any anybody got a part number for maf?

Cheers

for a standard LC your mass flow readings look about right!

When remapped you should see around 160 - 180 g/s on a k03s turbo which yours should be

hope that helps, get it remapped anyway, just take logs again after to see if you are getting in the above range.
