Jet's Tuning (Oh No)

[JETURBO]

So after having a moment in life where I thought about taking my self back to tafe to " gain knowledge " and better my self I have joined a dyno and basic tuning course on wednesday nights, puerly to better my skill base and gain more respect for tuning.

So as it stands last night was a blast ran over some safety stuff and got into it, we are using a mainline 500 chassis dyno and a mainline proflow engine dyno all latest and greatest gear

First up we ran through the screens/display on the monitors and went through different pages keeping note where to fill out info and make each run correct data wise for future referance, fair bit to remember but iam sure ill pick it up more and more

Intresting fact I didnt think was a mainline feature was ramp rates and the direct effect it can have on a run, honestly thought this was a D/D thing

First car up was a toyota corolla completely set up with EGT probes close to the head, and all the normal sensors connected as normal ( no obd2 )

Had a few runs looking at what to expect at idle and as temp rises, and the relation of the results and heat , then we started playing with a few timing marks and the effects of retarding timing and the way the egt's sky rocket with small ajustments ( crazy stuff imho ) and also the loss of power/torque readings

After we did a bit of theory we went to look at the engine dyno and the engines avaliable to play with, set up and real time tune. First off the batt is a GEN 3 with cam, hedders, intake using a autronic sm4 with Kalmaker software ( 350fwkw )

Also a red 202, boss 5.4,ecotech 3.8,4age, and some others .

Next week we will look at the flow bench and are aloud to bring in anything we want flow tested and some basics on CNC porting effects etc etc,

So far fairly stoked with whats happening and the fact we will be tuning cars with ecu's not just dizzys.tafe have been supplied a large range of cars including a 3.5 ralliart magna on NOS with ajustable shot and a VQ stato with 5.0, 5.7 vx wagon and the rolla and any car we want to bring along

The lecutrer has done over 6000 runs with not one poped donk so far so I feel its my right to bugger that right up for him with my car lol

Pourpose of this thread is to share my experiance and a bit of q and a with people who may know about tuning as HP TUNERS is avaliable for use aswell and I can see myself buying this softwear to eventually play around with

Good times a comming boys !

U forgot to add I answered your homework question for u

[freeze_dk]

Interesting.. Would you play with your tune?

[JETURBO]

Fark no freezer lol but that's saved on the flash 3 but ill definately load hp tunes in without a doubt

How else am I going to learn

[unclewal]

What is the course name?

[freeze_dk]

Yeah f*ck flash3, how often are you gonna change tunes.. I'm tuned with hp

[ratter]

does that dyno have the fuel module on it? if so run your car and record your data and see what is going on

[JETURBO]

It will be a wile before I do anything software wise but I need a good grip of whats involved first

does that dyno have the fuel module on it? if so run your car and record your data and see what is going on

I will definately ask

What ramp rate do u use for our cars mick 2 or 3 ?

[Ralph Wiggum]

*headers

*while

[ratter]

I do not have ramp rate like that, I pick the klm per second and normally use anywhere from 10-15 klm per second based on how much power the car makes etc, Mainline recommend using a ramp rate which gives similar accleration to on the road.

Mainline dyno sheets show the ramp rate of the car.

[freeze_dk]

Hey mick, how much do you charge for a run up on the dyno with all the fancy fuel things connected? Tried to pm you but kept getting errors..

Sorry jet. No pics

[ratter]

a set of runs with fuel module data connected and recorded is $150

[Frederick]

Ratter does em for free when u give him special cuddles lol

[JETURBO]

Hey mick what rail pressure do u like to see at redline with 98 fuel and one 044 ?

[trbo 6]

Have you got any info on the course Jet? Course number maybe?

[freeze_dk]

Thanks mick

Back to the chlorophyll

[JETURBO]

Umm ill have to get back to u on that one

Its something like test engines and dynometeres

[ratter]

Ratter does em for free when u give him special cuddles lol

only when jet wasn't looking

Hey mick what rail pressure do u like to see at redline with 98 fuel and one 044 ?

if the system is working correctly you should have 4 bar plus boost pressure or close to it, you should also have some fuel left in the return line

[trbo 6]

Umm ill have to get back to u on that one

Its something like test engines and dynometeres

Found it. Thanks mate. Not sure if it's run as a short course in NSW though.

[Ralph Wiggum]

Does your gear measure supply or return flow or both ratter?

[ratter]

flow through inlet, flow through return, pressure on inlet, fuel temp, ethanol content and then a heap of calculations based on retrieved data

[JETURBO]

Hey iam gunna keep asking questions and u can tell me to bugger off if iam delving into the secrets of your tunes ok cause I dont know where the line is

So when it comes into timing on a na engine how much timing advance would u run at max torque ?

Is there a rule of thumb on how much timing u need to be away from knock conditions ?

[freeze_dk]

why dont you chuck your car on the dyno so you have more knowledge of the actual car your thinking about playing with?

[JETURBO]

Yes that will happen

But that isnt the point of this yet its about some base knowledge and build from that, something like this takes years to perfect and iam at the bottom

Plus id rather flog the guts out of tafe cars wile learning the basics

[Mr_4.0]

I've never found a set "rule" when setting timing on na cars. There's a little trial and error involved. Two ba xr6s might take quite different timing at max torque to be optimal. A lot of things can make this figure vary.

How far you wind the timing back from detonation is personal preference. Its a question of "how safe do you want to be?"

This is my opinion.

I wouldn't mind doing a course like this.

Which TAFE is this through? Curious if one in my area has something similar.
