The Tuning Talk Thread - Forced Induction EFI & JZ Tuning.

[OnAll-FOUR]

I Received this email from Wolf EMS today about an online training course they will be running. I thought some people on here would be interested.

Hi Everyone,
The response to the first training email has been amazing.
People are after more information, so here’s how it will work:
The training will be conducted over 3 weeks on:
Thursday the 15th of July at 7pm ( Melbourne Time, UTC +10 hours )
Thursday the 12nd of July at 7pm ( Melbourne Time, UTC +10 hours )
Thursday the 29th of July at 7pm ( Melbourne Time, UTC +10 hours )
As this is a live, on-line course, you can be anywhere in the
world and still attend.
At the end of the training, you will receive a certificate with your
name on it.
What Equipment Do I Need?
You will need a computer connected to the internet with at least
1500kbps download speed.
As this is interactive training, you will preferably have a headset and microphone
so that you can hear clearly, and there may be times where you can
ask questions of the trainer.
We will also ask you to send us any questions you have ahead of time,
so that we can cover the most common questions during the training
series.
So, that’s all for now. We will be in touch soon with more info.
Until then, best regards,
Steve..

P.S. Feel free to forward this email on to anyone who you think may
benefit from the course.

cost of course ? links ?

[OnAll-FOUR]

Free as far as I understand, and it will be a webcast. You can sign up for their emails on their website but I will post up any more details I get when they come through,

EDIT: I was wrong about the price

Hi Guys,

So, it looks like we are ready to start taking sign-ups for the
Wolf Training that begins on the 15th of July 2010 and runs
for 3 weeks.

Here are the dates:

Thursday the 15th of July at 7pm ( Melbourne Time, UTC +10 hours )
Thursday the 22nd of July at 7pm ( Melbourne Time, UTC +10 hours )
Thursday the 29th of July at 7pm ( Melbourne Time, UTC +10 hours )

For registered participants, we invite you to email through
questions before each weekly session, so we can ensure that
you are getting the most out of the training. Although we can't
guarantee that every single question will be answered, we will
do our utmost to go through as many as possible.

Numbers:

As we want to ensure that everyone has a great experience
and the training runs as smoothly as possible, we are limiting
the number of participants to 10 people.

What if I miss out on one or more of the live sessions?

We are going to record these training sessions, and you will
be given a special link to the recordings, so you won't miss
out on any of the training.

You will be able to download these recordings and listen to
them any time you want.

The training is being run by our Technical Support Manager,
Robbie McQueen. Robbie has more experience than anyone
when it comes to training people, tuning, and setting up Wolf
ECU's, so you know you are in the most capable hands.

One of the common questions people have been asking is,
"What is the cost to register?"

By having this training online, we have been able to keep the
cost as low as possible.

The total price for this training is AUD$127 for all the live sessions,
and the recordings.

All you need to do to register is send an email to
[email protected]. We will then organize payment
via PayPal, Credit Card or Bank Transfer.

That's all for now.

We will be in touch soon,

Steve, Robbie and the team at Wolf.

P.S. With the number of people asking for more information
from previous emails, we expect this course to fill up pretty quickly,
so don't miss out. As we currently don't have another course
booked at any time in the future, we can't guarantee that you
will be able to book in for any training during this year.

P.S.S If you have any questions at all about the training, please
contact us at [email protected]

What ECU & engine you have
Stock 1J Single turbo TR44Hiflow. Apexi Power FC (A.P Engineering Pro)

How you are tuning that ecu
I have borrowed a FC Datalogit

What wideband o2 and knock detection do you use and how is it integrated with your ecu
Inovate LC-1 Wideband with XD-16 gauge with 0-5V logging output

Knock detedtion 1JZ's factory knock sensors

Are you using a Dyno or street to tune, or both?
starting with Street but will prob hire a dyno not sure yet ( not at this point)

Are you tuning from blank maps or using a 'base map' or someone else’s hard work
Base map

Your opinion on withholding tuning tips or secrets or even your own data and maps from persons and for what reasons?
share it out but I am verry Green to tuning at this point

What modifications you have done to your engine and how they affect your existing tune, or how they are have increased/decreased difficulty to perform further tuningSard 650cc's, Hypergear TR44 hiflowed other than that stock engine
only just put the Power FC in but was running Stock ECU for about 2 years around 17-18psi boost ran great but time to get more out of the engine and more boost

Your experience from tuning timing.
some time ago I had a play with the FC with out a wide band but with loging I pulled some timing under high load to reduce the knock I was geting help some what but still got spikes of knock that I could not explane why so with out the wide band I decided to put the stock ECU back till I was ready with a wide band and hopfully a bit more knowledge in tuning

Your experience from tuning fuel.none as of yet
Your experience from tuning around knock.
none yet but plan is pull some timing first to keep it safe then attack the fuel get that right then back to timing


How intimate you are with your ecu, have you learnt every feature and what it does?
so far only basic but have been doing alot of reading from the net and from others that are sharing the info on what each setting is and how it affects the tune

[Jabtronic]

Quick question on road tuning. If I was to road tune my car as far as possible for the fuel map, and then take it to a tuner to get the timing tuned on a dyno. Will the fuel map need additional tuning afterwards?

[mr1jz]

In short, YES.

The varying amounts of timing will affect the AFR's. The more timing, the more fuel. If you get your fuel table close then it is less time the tuner will have to spend on the dyno.

[JZA70 R]

spot on



.

[1JZ-Rolla]

If your timing figures aren't wildly out to begin with, then the fuel tables should only require minor corrections by the tuner on the dyno. Timing adjustments do have an affect on AFR, but not wildly.

Cheers

[JZA70 R]

With my particular car, increasing timing would fatten AFR's and decreasing timing would lean AFR's.

As said above, AFR's usually only slightly affect AFR's, but that does depends on how much timing you add or remove.

This is a dyno sheet showing what the difference is of up to 4' of ignition advance makes on a given AFR... on my car.

[oldcorollas]

are you talking about amount of furl you put in? or the AFR feedback you get out?

AFR measured at full noise also incorporates an element of incomplete combustion, so more appropriate advance = better burn = less oxygen left = "richer" mixture, but still same amount of actual fuel going in...

or is that what you are already saying?

edit.. swings and roundabouts i guess

[JZA70 R]

I was trying to depict what effects ignition timing has on AFR's when no other changes (to fuelling) are made. On my particular car, adding ignition timing would yield a fatter AFR. This is only relevant to WOT dyno tests. I understand lower loads (and different engines ect) may produce different results.

[oldcorollas]

makes perfect sense and is reflected in your power output too..

[OnAll-FOUR]

Hmm let me see if I have this right in my head. So I understand that lean conditions under load are bad for detonation, but if the same amount of fuel in gives a leaner afr after a better burn, what is important to stopping detonation? would it be ideal to measure AFR in the intake in that case?

Because isn't detonation a event that happens pre ignition therefore, the same amount of fuel in will give the same resistance to detonation?

[oldcorollas]

other way around?
O2 sensor only measures residual oxygen in the exhaust gas

a poor, less complete burn will leave more oxygen in the exhaust gas to measure, and looks like a leaner mixture.
missing also looks like lean mixture (which is sensible as missing is a really incomplete burn )

better burn = less oxygen left in gas to measure = looks richer.

detonation is uncontrolled high speed burn (self ignition?). (pre-ignition is different thing in my mind)
richer mixture slows down burn speed and reduces chance of detonation.
so if the burn is slower from more fuel, or the burn is more complete, both will look "richer"

then you juggle pulling out fuel AND pulling out timing to compensate for faster burn, but still have same measured AFR (residual oxygen).

[oldcorollas]

hmm... how about this.

you want the air/fuel mixture to burn.
if there is not enough fuel, then it changes from "burn" to "explosive" (well.. faster burn)

so you need enough fuel to make the mixture burnable instead of explosive.
the amount of fuel for that mixture will change with the temp and pressure in the cylinder, which will change with timing, so you could say that the ideal mixture will change with timing and cylinder conditions, since you are balancing burn speed with timing, so that the cylinder peak pressure arrives at the right time to make good power.

edit: pre-ignition and self-ignition are different issues...
