Agreed.

Get fueling dialed, then I would say you're good for a stage1.

Sorry, added some nits to my post just now Smiley

Fueling still needs some help. Might be able to add a bit of timing.

Sorry, added some more questions to my post Grin, everyone likes to edit around here, including me! I need a few tables added to the xdf, and some pointers on fine-tuning the fueling from the experts. I'm going to go read the S4wiki about the timing maps and how to tune.

I am not positive on how accurate the definition of some of those fueling maps are at the moment.   

We need not worry about timing until we get fueling sorted first as fueling will determine what sort of advance we can run.

All you really need is FBSTABM and TABGBTS. Should be sufficiently high to begin with, but these 1.8t's tend to run high calculated EGT's.

Ok sounds good. Could I ask for the addresses?

I think this is getting a little ahead of ourselves.  We still need to correct LAMFA fueling before we even think of messing with BTS fueling.  Proper LAMFA fueling might even keep us from entering bts enrichment, or at least make the onset come on later.

Step 1 IMO is to verify the map defintions for the zk and tlafa maps and understand how to use them.  I hate those maps.  Smiley  Not making this a very easy Stage I.

I guess the other option might be to set lower values in lamfa, but I'd just feel dirty doing that.

Keep an eye on IDC when tuning these. Non-return fuel system is a bitch.

Agreed. LAMFA first, BUT:

zk and tlafa

From comparing lamfaw and lamfaws, TLAFA seems to be zeroed properly.

ZK is getting there. We aren't that far off as far as LAMFA goes... i think it would be safe to start addressing BTS onset as well, even now.

Keep an eye on IDC when tuning these. Non-return fuel system is a bitch.

Looks like IDC is maxed as soon as BTS comes in, but we're still close to requested, so we aren't entirely f'd. Might want to tone down req load near redline anyway.

nothing but lamfa and it's % axis has been modified in this file as far as fueling is concerned.

Ok. To simplify things we can also just bring lamfa in earlier..

Start enrichment at say, 70% pedal position and ramp towards 100%?
