cool. Why does it run so rough?

haha, I was about to say "it looks like its about to shake a spark plug boot loose" and then 3 seconds later it did!

Motor running rich and idling is badly affected. Still working into it!

Also badly in need of upgraded rear mounting

Will update when I have more cash!

nice video!

by the way, i just want to share that although my tuner thinks that doing a recirculation is the fastest and easier way, he provided an alternate option if i wanted to stay venting to atmosphere which is to perform a MAF sensor relocation to a pre throttle body and post bov location.

That will only work as long as the MAF doesn't also have the air temp sensor in it.

Just a thought where I can get some information about general ecu mapping and tuning. I want to consider tuning my engine myself but I need to get the know how when and why etc...

If any of you have any link to some website or if any of you is already a tuner himself could give me any tips would be much appreciated!

Parmas · 05-28-2009, 07:08 PM

Today I tried to understand by myself how to manage fuel and ignition. Well the tuning is fair easy to control and to manage but there are some things I still don't understand.

First I am confused what is the difference between micro fuel injection and normal fuel injection?

What about Injectors constant and latency values? From where do I get them?

Acceleration map, sensitivity and decay?

Second how could I understand when the ignition map is ok at that particular rpm? (In the ignition map shows constant ignition on all rpm loads)

What about ignition angle and coil charge time? Is there any need to change?

What is the best to reference on the mainfold air pressure sensor or throttle position sensor?

I know there are many questions here but I would be pleased if some of you can make me understand more as much on these!

CASTREX · 05-28-2009, 07:34 PM

Not to pull you back.... but,

With ALL the money and time that you have invested on this car so far... are you going to cheap out on the most critical stage????

If I were you I would go for a Pro tune...
You know you can kill your engine with a bad tune?? It would be a shame!

Is cool if you want to learn about tuning... but perhaps you can pick up a beater car and practice on an engine that you wouldn't mind to screw up.

Just my 2cents

I totally agree with your response I just want to know if the tuner made everthing right regarding mapping and settings.

On the other hand if the tuner makes a bad tune himself I would be more shame to pay for his time (which is not cheap btw)

Also I am considering that if it happen to notice a misfire on a particular gear and rpm I would be able to set it myself.

I know I am not a tuner myself and I don't pretend to set all the rpm loads on all gears by myself

CASTREX · 05-28-2009, 08:25 PM

Good luck to you then! just be careful

Tuning is very easy as long as you have the knowledge, i suggest you go onto boards like romraider or pgmfi and start reading up on guides, it will help you greatly

First I am confused what is the difference between micro fuel injection and normal fuel injection?

What about Injectors constant and latency values? From where do I get them?

You need to find out what the stock latency is(probably can do it with an oscilloscope, and measure pulsewidth? i dont remember how they do it from scratch), but settings the latency is the proper way to size injectors... if i recall its (new inj cc/old inj cc * old latency = new latency) or something like that, the formula is everywhere

Acceleration map, sensitivity and decay?

I'm taking this could be throttle sensitivity map, only thing ive ever seen with decay is knock so i wouldnt play with that or your car might be jittery, but sensitivity should be 100 across the board. You let your foot do the judgement, it will feel like a totally different car, my truck became a monster after, and remember its all based on load, so you won't go WOT from just tapping the gas

Second how could I understand when the ignition map is ok at that particular rpm? (In the ignition map shows constant ignition on all rpm loads)
Depending on if you are controlling ignition with your management unit, a constant value across all load is very bad. You could either be losing power/fuel/damaging the engine... they can usually get a basemap if its wired from the ecu, if not they can get one from another 1nz-fe engine map thats not the yaris

What about ignition angle and coil charge time? Is there any need to change?

What is the best to reference on the mainfold air pressure sensor or throttle position sensor?
please clarify a bit

I know there are many questions here but I would be pleased if some of you can make me understand more as much on these!

I tried to give pack as much info as i could with the time i have right now, i didn't comment on some things, because i don't think you need to worry about them or need them

Parmas · 05-29-2009, 02:00 PM

Thanks for your answers ... here is the setup screen where you can select which load input the ecu has to refer on as primary input

You can refer to the previous page to see some screenshots maps from the ecu

Nexus1155 · 05-29-2009, 02:20 PM

Well if you don't have a map sensor installed you can only do it based off the throttle position sensor....

but if you do have a MAP sensor that you added, it should be TPS for whatever is out of boost and MAP for when it hits boost. So it would be one of the bottom two...

Parmas · 05-29-2009, 02:38 PM

What do you think about ignition compared with fuel injection?

And btw what is micro fuel injection?

cali yaris · 05-29-2009, 02:49 PM

Tuners here don't let the car leave until the job is good and complete. I heard your motor in the video. Hopefully your tuner is not saying he's completed the job?

As CASTREX correctly says, this is the most important step of the game, and if it's done WELL, you won't have to do very much at all, and especially you shouldn't have to correct or fix something the tuner did wrong.

Nexus1155 · 05-29-2009, 03:49 PM

It looks like a good management system, but it looks like it displays wacky, if it was just numbers it would be easier to view and easier to tune with. The injection looks fine, i don't know what AFR you are seeing, but ignition is wrong if in fact the harness is hooked up to control ignition...well see it also depends on how ignition is controlled on this management, thats whats weird, so i can't give you an exact answer, but on the video it definately sounds off if youre not cammed with a big lopey thing

Parmas · 06-07-2009, 05:19 PM

I wish to understand exactly why my motor is running bad idling.. The idling of my motor sometimes varies from 800rpm to 1300rpm... well I want to know what is the thing that makes this and what is related to.

I know that it's probably a tune up problem but what could be the things the tuner should consider... ignition maybe fuel or a sensor?

So I ask, what electric and mechanical components in a setup like mine should affect idling? What things you guys suggest me to check?
