Kenneth's ECU Mods V1.03

[Davezj]

I am try to get him to explain what his is doing and trying to do in a clear and concise way.
Which he has not done yet.


If you look at the rom he sent over which he said is the rom he is using he has only set the timing to -10 not -20 or -40, but -10. So I don't see how he can get more than -10 degree of retard.

I am trying to get him to help himself and show us what he is actually doing not what he thinks he is doing.

It is very easy to get it wrong, and he is obviously getting it wrong and he doesn't know it. he only has the timing set to -10 degree.

Personally I don't run pops and bangs it is a pointless and some what childish thing to do.
However childishness has its place and we all like to indulge our inner child every now and then.

The rom I posted up was from a car that successfully had pops and bangs setup on there car and does pop and bang on over run. But it does depend on what exhaust is fitted. As silencer/mufflers can deaden the effect massively as we found out.

Yep Nick is right. I can set retard below - 10 in the ign map. But I can't change the max retard.
There is an error somewhere in this rom. Cuz merlins Guide says that the max ign retard can be edited with the formulas and paths, which are in kenneth rom. Dunno what's wrong.
@dave: I know what I'm doing. The problem is just the max retard limit which can't be changed.

[Davezj]

You need to be clearer on what the issue is and what you have done to try and diagnose/fix it.

Obviously pops and bangs are achievable with the current rom because there many people that have it switched on you just have to look at all the cars at the rolling road days with it switch and displaying it.

The ignition retard not going below -10 well that is interesting.

Yep ign is limited to -10. The rom does not care about the ign tables below - 10
Max ignition retard is the value which limits the retard. This needs to be fixed
Sry but I can't write anything I want in English

[Davezj]

by the way don't believe everything you read in merlins guide make sure you double check it and confirm the result, there are mistakes in it from what i remember when i first started looking into ecu modification stuff. it has been created from the Evo guide and he seems to have left some of the evo stuff in there that does not apply to the VR4.
i am not having a go at merlin i think he has done a great job, but there is some misinformation in the document.

Philipp, how are you testing this?

It may be an issue with the anti-lag retard limit, shown here.

I don't think so. Ive set it to - 15

I'm testing it with evoscan logs

[Kenneth]

You are going to have to be more detailed in what you are doing, both with what you are logging and how you are driving the car to test.

Telling me you are using evoscan does no help in any way.

If you don't provide sufficient information for me to help, I'm not going to.

20160930_071804.jpgYe ok, sry
So, I've set timing in ign map to - 20 from 2000 to 5000 in the first 3 load columns. In evoscan I take a look on ign timing while overrun in this rpm area and it shows - 10. Even if I go up in load column to 10 load with a little step on the throttle pedal i just get - 10 degree.
For any reason I think there is something wrong with the xml files. Somewhere needs to be a barrier :/

[Davezj]

which tables are you setting the ignition timing in, you need to set it in all 4 ignition tables to get it to work, are you doing this?

[Xaxasv6]

No I don't do that cuz as I know, high octane is being used since it knocks.
I put pops and bangs in high octane.
Davezj thanks for your help but we need to find what's limiting the max ign retard

[Davezj]

All I am going to say is lo octane map must have lower values it than hi octane. If you are not doing that, I give up.

If you have detonation issues, you need to sort that first.
Doing this sort of stuff before covering off the most important tuning issue is stupid. Not only that, it makes any other tuning really hard because you are interpolating between high and low octane maps and your results are going to be very difficult to verify.

[Xaxasv6]

No I got no detonation issues. The only issue I have is that the rom limits the max ign retard somewhere

Hello i have tactrix 2.0 cable
Can anyone explain for install this rom?
Im flash with error metadata and definition.. thank you

[Davezj]

try looking through this thread it has all the info you will need to be able to modify you ecu rom

how you choose to modify you ecu is up to you.

[Xaxasv6]

Still no way to raise the max ign retard limit ? :/

[Confused]

Are you sure it's not using the 'AntiLag Ignition Retard Limit'?

[Xaxasv6]

No it doesnt :/

[Confused]

What does that mean? Help us help you, here!!

Have you changed that value and noticed that it is still only using -10?

Also - is there any reason why you're not using Ken's 2.0 ROM - that has had more development, is being used by more people, and is more likely to be updated than this old 1.03 version is
