No, Id like to fit one sometime, but I rely on regular logging with vag-com. Block 31 on a Leon gives its wideband lambda.
Depends on your mapping, but you'd be looking at your a/f dipping towards/below 11.0 as evidence you're burning the methanol.

I think that once you take a car beyond stage 2 - by whatever means - you really should know exactly what's going on with your fuelling.
You could advance timing a little bit by checking CFs, but I'd advise against large increases before you get an a/f meter.
I'm fitting a safety device which will cut my boost if the methanol stops flowing.....

Thanks for that Dave, advice taken on board and wont be ignored, what kind of increase would be acceptable without the AFR gauge do you think?
I have the float switch with my install with a warning LED for when it gets low, im going to install a On/Off switch for the pump for when the meth runs out and just stay off boost until refilled.

Thanks Dave.
I`ll be getting some logs tonight, just didnt have time yesterday
What things would i be looking for when logging to determin if i need to change down a nozzle size?
Also is best to have the controller to start spraying as low down as possible without bogging it down?

Odd misfires top end under load. The thing is, you don't notice - there's just too much methanol in there. It reduces my torque.
Yes, if you can get some methanol in while it's spooling, good, but it will bog down if it's too low.
What recommendations would you make if you're running on water only?
I have an LCR with a hybrid k04 that runs max boost of around 27psi and holds around 18psi to the redline.
I have the nozzle fitted just after the forge fmic (behind the foglight) and I've set the controller to start at 8 and on full at around 18. Nozzle I'm using is a D03 (189ml per min)

WMI running would see right - have you got logs of intake temps and CFs? I'd use an mbc to calm that boost spike, things have got to get hot from that......
Sorry its taken so long, but here they are at last.

Could sombody explain what the ign timing figures mean and what i should be looking for.
I havent advanced the timing yet, im going to advance to 4.5degs as dave stated and re-log, i doubtful if ill see any movment, currently running 25% meth.
Seems to of helped my intake temps no end, although as not as low as they could be with a better FMIC its a vast improvment.
quick boost log, anybody think it looks abit iffey where the boost drops and pickes back up again?
I maybe barking up the wrong tree here, but can the spring in a new actuator get softer over a period of time causing a small loss off boost, i`ve currently lost a psi of boost with all pipes good and secure, i know that cranking the wastegate will get me my lost boost back but i dont just want to cover the problem.

Your boost is pretty stable there. (requested, actual).
Good logs. Column 5 in 003 shows the amount of ignition advance (before tdc) that you are running. It's here that you should see improvements if you advance your timing.
Good logs. Column 5 in 003 shows the amount of ignition advance (before tdc) that you are running. It's here that you should see improvements if you advance your timing.
Theoretically, advance by 4.5 degrees and that should increase the numbers in that column by that amount. (but it doesn't, due to sampling rates of vag-com and that timing advance swings back and forth as the ecu tries to meet requested loads).
I'll pass on the actuator spring question (I don't hold with most of the stuff that's talked about fiddling with actuators and springs
)
Plenty of duty cycle left in the n75 valve to make more boost, its a case that the map isn't requesting the boost you want it too. Actuator spring is good .
Good to see that with wmi activated your cf's are nil, extra power waiting to be unleashed.
Keep the car, get some rods in there and up the boost.....happy days.

map is asking for exactly the same 'airflow' to achieve the torque request, achived via boost... so denser aircharge, cooler weather now, will all have an effect. Map does not change, ambient conditions and mechanicals do
people continue to get fixated about the boost.. ME7 does not run fixed boost requests, an external EBC will, ignoring ambient conditions, where the Me7 is trying to compensate for the ambient conditions and sensor inputs its seeing.. MAF g/s, AIT 'C, MAP pressure kpa etc etc
An actuator can relax, and adding some preload can recover this (shorten the rod length)

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.
hmmm I want more boost, {reaches for actuator rod and MBC etc}
So if i understand this correctly.... so long as the n75 valve is the sole means of boost control the ecu will adjust the boost up and down to make the same specified torque request which is measures by evaluating the mass airflow.
If i make modifications to my car and don't see a significant increase in performance or mass air flow it could be because the map is winding back boost or injector duty cycle since the car is making the same torque only with less effort. A map adjustment would be required to see the modification benefits.
Am i on the right track here.

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.

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.
