On another note I've picked up s t04 garrett. Might be too big, just need to find some time to take it to a turbo shop and see what they can tell me. If no good I'll sell it and get the axt turbo and manifold.

Yeap.. For sure mate.. If i've done this right... Im kinda hoping there will a pic below this somewhere...

As i said before thou, this is only very basic tune to gett me around the place. And its running rich as hell

Have you got a better copy so we can have a look mate...

Goid point JFF45 on injectors. But I will be replacing rods so might as well do it once if I get power hungry.
MS3 I would prefer but I do not want trial and error in this area. I can not tune it myself and if local tuners aren't familiar with it I'm stuck. Not to mention I don't get a lot of spare time anymore so installing it could be a pain..

The only reason I went 740 cc injectors is because I want the ability to run E85, which requires around 30% more fuel flow. 550 cc injectors will have more than sufficient duty cycle for 12 psi on petrol. Don't go any larger than you absolutely need to.

Another thing worth noting - Jose, I noticed you have the O2 sensor located in the exhaust manifold. Be careful with that, especially if it is a wideband sensor. Wideband sensors are sensitive to overheating in that position, and their accuracy is also substantially affected by the higher pressures. In the worst case, the sensor could fail and allow pieces to pass through the exhaust turbine. A narrowband sensor is less problematic in terms of heat/pressure sensitivity but the risk is still there of the sensor failing and dropping its guts through the turbo. In fact, I had a Bosch narrowband fall apart in my exhaust when the engine was N/A, leaving a big bit of metal sensor cage rattling against the cat!

For best accuracy and sensor life, wideband sensors are usually best installed approx. 300 mm downstream of the turbo, ahead of a cat (if you have one).

With a bit of zoom looks like 150 rwhp?

I've mentioned this in the TB45/TB42 factory timing curve thread - the TB45 cam and intake combination is much different to a TB42, which prefers fairly constant timing above 3000 rpm, and it doesn't need much timing advance at peak torque (3500-4000 rpm). The chart attached indicates the volumetric efficiency (i.e. torque curve) of the engine. As a ballpark indication, the factory engine at full load likes near 30 degrees of timing as early as 2500 rpm, with a dip to 27 degrees at 3750 rpm before increasing to 34 degrees by 4500 rpm. I'm sure your tuner is aware of this - but just in case....

Just following on from Scott's comment on the O2 sensor, I've had an Innovate MTX-L wideband sensor and gauge for several years now for tuning with the Xede.
I located it vertically (most recommended postion to eliminate all moisture ingress) in the section of pipe in my Pacemaker extractors where all the pipes come into one.
This is about 300mm before the cat and I'll be using the same postion when the turbo is fitted - also because all the wiring is already in place there.

This sensor also supplies the narrowband signal for the ECU so you don't need 2 sensors.

Here's a better pic of T bone's graph. Remember this was taken with no intercooler yet and a basic fuel rich tune so it isn't a real indication of the potential of the installation.

So peak torque at roughly 3000rpm and peak hp at roughly 4000rpm. Thought it would have kept climbing a little longer?

Peak torque should be at peak VE - so around 3750-4000 rpm. Peak power will be somewhat after that, probably around 4500 rpm. My hard rev limiter is at 5500 rpm and it pulls quite hard up to that.

Ok so T bones results are due to tune settings?
I have read the graph right and that's what it says?

Re-read T bone's 1st post where he explains that he had no intercooler and was running 95C intake air temps. The graph is marked as 'Baseline test'..

Definitely. I'm certain it's got more power up it's sleeve for the same boost level.

Did read it. Just asking the question. The curve drops off as if it was all it had. Not a sharp drop off like i would expect if the tunner dropped off the throttle for safety reasons. Not that I know much about dyno techniques.

Would have thought so. Just wanted to make sure 4000rpm wasn't the usual drop off.

It will have more power because those figures are only slightly higher than an N/A TB45E with a good exhaust and tuned piggyback..

 

[DieselTuner]

The intake and exhaust setup will have a decent bearing on when peak anything is though.
Having a ve plot to suit an engine is all well and good unless there is variables in setup like intake/exhaust/cam, let alone turbo specs...

Looks like about 3100rpm on that is needs more timing in it though. Is there a boost/afr curve from the tune?

 

[t bone]

Hey t bone, spoke to a guy who installs wolf ecu's and he said you can change the signal from pisitve to negative in the programing for the A/C.

Sent from my ASPERA R5 using Tapatalk

Cheers for that bud. Whats the chances that he mentioned any more details too? Ive had a quick flick thru the program (at some stupid time of the morning before leaving home for a month thou) and couldnt find anything regarding polarity options :-/ You have made my day with a little ray of hope thou for sure thanks again...

 

[t bone]

Sort of. I've only got the picture on my phone out here at work, and im not home for another few weeks yet. When i get home thou ill post the original one, as well as the new one from the tune with the A2W intercooler up and running.

Gday bud. Ive just pulled the pic i have from my thumb drive. your bang on the money. It says the below information up close.
MAX - 353.9N.M @ 124kph.
POWER - 154hp @ 136kph
MOTIVE FORCE - 729.8LB @ 124KPH.

What they all mean to the trained eye, i've got no idea. I just know that it "feels" like a lot more power and response than before. But the lads at the shop keep telling me that its got nothing as compared to what we will get with this next tune.

I have gone thru your information above about 7 times now. But with the whole, awake for 20 something hours at this stage,with another 7 to go- its just not sinking in to be honest. The shop where i was getting my work done down in the city has now got a new dude doing the tuning, so its going to be interesting to see the difference in techniques and what they can do. Hopefully he will already know the above info you shared scott, and if not, he might be able to explain to me in simple mans terms your info.

I've already attached the copy you sent me in post #86. You must have missed it..

 

[ASH929RR]

So has anyone done the upgrade to there rods or are you running standard rods...
I take it ''T Bone'' that you are running a manual gearbox by the looks of your dyno and what diff gear are you running..
