Setting up WMI - Logs up.

[DaNnY_LaD]

you want to be as near as dam it to 11.7-12.0 afr on wot

 

[__B3NNY__]

Of course. The thing is, people seem far to ready to start fiddling with their actuators without diagnosing the real problem with their motors. I'm sure you've noticed this, Bill.

This is the reason for my question, i didnt want to just adjust the actuator just to get my boost back if there may have been a problem else where, which is why i asked if it was possible that the spring can get softer, as id only lost approx 1psi and all hoses clips seemed good so if the spring could sof`un it seemed possible thats where my 1psi might had gone.

Bills PM made perfect sense, as im getting the same airflow 220g/s for less boost, so happy days?

I seem to get consistent 219\220g/s when i log 002 as a single block.

So what would be next for me? Add the timing and relog? Is there any need for a more of a % mix of meth? currently running 25% with those logs.

Add timing and relog

 

[ibizacupra]

So what if you do throw in an EBC into the mix, are any other parameters affect? Are any timing or fuelling pulled back due to the fact an EBC is in control of the boost?

For instance, if you hit limp mode for whatever reason would anything actually be affected or would you just see a light on the dash as the first noticeable thing in limp mode is lack of boost, but with an EBC you wouldnt see this.

you can get a liimp mode if the limits of deviation are left std, so yea it can do, but can also not do if those limits are raised or even removed.

ecu will presume to fuel for the air mass its seeing, boost etc, as best it see's fit. leon ecu's do this better with their wideband control, where ibiza's run dumb ass ecus relatively

it will do its best given its tables looking at load, rpms, throttle position air mass, ait's etc etc

Thanks for that bill, the deviation on Stage 2 must be pretty wide as ive never hit limp mode for positive deviation and im maxing out the MAP at some points.

 

[DPJ]

Isn't it a % over requested?

 

[wild willy]

yep, when ME7 is adjusted to still run this control thats what it should do...
however, the ecu can be made to ignore some of these tables, and get driven to do as its told settings.. depends on how its mapped.

I mention it as there is the fixation on boost by most people, but its not the primary ecu setting, just a function used to achieve a load setting. Its not a 1:1 thing, which is why it often seems variable, as vairable as atmopheric and weather conditions in fact. AIt's, EGT's all factor in compensating tables, which makes it difficult to tell exactly whats cause and effect at times.

I like my stand alone DTA a lot, as it does what its told, and does'nt think so much on its own.

Top info, thanks Bill.

Isn't it a % over requested?

its whatever you want it to be dave I think.. its just hex code in whatever scale you choose to think about it in.. 0-100% 0000-FFFF

I have my WMI running off the washer tank which I think is 3 litres. Is it normal to use a a full tank over 140 miles?

I'm running water only at the mo

It's not uncommon - it depends how much 'boost' you've used.

possibly coming on too early, or you are on 'da boost' a lot

 

[jonathanp]

well the thing is, it was the mrs driving to hereford and back. So probably was on the boost, she's either idling or WOT so thats probably why, lol

water injection comes on around 11 and full at 20 might change this to 13 or 14.

Once I've got some methanolbill I'll speak to you about getting it setup

 

[ibizacupra]

its got a thirst has'nt it... mine when I ran last started at 15psi and was full on at 23psi using 50/50

 

[jonathanp]

Few logs from last night, normally don't see any timing pull but saw up to 6 yesterday and 5 minutes before that I saw up to 3

I'm also getting timing pull at really low revs (normally 0.8, 1.5, 2.3 or 3 ) normally for 2 lines then gone , somtimes even on idle

 

[ibizacupra]

this on just water?
is it spraying all the time?

have you checked by visually seeing when the start spray starts ? (not easy I know without pulling off the feed pipe to where you can see it)

 

[jonathanp]

yeah this is just water

set to start sprayng at around 11psi and full on at around 20psi.

I haven't checked visually nope, not sure how I could unless on a rolling road

 

[ibizacupra]

pipe extended onto the end of your pipe and drive it so you can see it squirt on your screen when it cuts in

(what I have done in the past)

Snow kit has a telltale LED that lights when it's running.

Mines set to come on at 9 and full by 17psi, i`ve managed to use a couple of 3 quarts tanks within a 1/4 of a tank of fuel this did involve a few logs and quite a heavy right foot!

Added 2degs on top of what bill had dialed in (3.75), going out to relog tonight.

I'll see if I can find something like that, also need to block the port on the joiner as there is no way I'm putting the old one back in, lol

I have my controller mounted under the bonnet though unfortunately


Is it normal to get CF's at low revs? Timing advance at the moment is 6 degrees, which shows no CF's under normal driving although I might drop this down a touch
