Sorry am I missing something. Micks tune is showing .85 lambda throught the curve. My tune at its worst part is .88 lambda .

Is that enough to cause a issue like this.

Each tuner has there own way

0.9 lambda is used by some others will go .85

See how small amounts can influence different outcomes, pressure is moved by large amounts on small tweaks

Your sheet should be up around 12.8-13.2

Do you always act like a child or did I catch you on a bad day?

^this.... Reasonable question being asked yet you are persisting with the cryptic answers.

Either help him out or don't.

Who's being a child ?

I told u to make an effort when u gave a dud response

Then I've made u actually think for a moment and you still don't like the answer.

I can't help you anymore, it's fairly simple do as u please I can't make people listen and iam not going to beat my head against the wall trying to help you if you cant keep up

Like I take anything personally so why would I get upset lol

Over the past few pages I've told you how to fix your issue

Over to you now .....

I'm struggling to see the difference between my curve and micks.

All I can do to limit problem is decrease cylinder pressure , ill still have a chat to my tuner and see the differences he tunes between stock engines and built engines and make a decision from there.

My initial thoughts are I can't add washers as my head is already compressed a little so I'll have to stick with the washers I have and go to a single gasket , as well as a little less timing and initial boost.

Lambda result is a cylinder pressure adder/subtractor

My complete point the whole way ?

This thread got out of hand real quick.

So what a gathered for an e85 tune dont go crazy on timing because of cylinder head pressure and keep a relatively lean AFR?

Which goes against everything you typically here with e85. I have just reached the limit of my setup

Timing can be whatever the engine can support it's the afr of e85 that can be leaned on and for obvious previous reasons

Many many 500+ cars running a different target lambda on E85 against their 98 tune

Smacks head against wall ...........

The top part of that paragraph is exactly what I said to you in page one

But what would I know

Again

It's counter intuitive. I read the top part of the paragraph and it says go richer with less timing to save the motor, but when your on the edge of pushing timing to the limit you need to lean out to make the power, without breaking something.

I've always heard with any engine standard or forged on any fuel in street cars to not go crazy on timing.

I've always preferred smashing more boost in than adding timing.

Less cylinder head pressure is always a good thing in my books

Smashing more boost in and less timing doesn't really help the motor, for example if the motor is making 400kw on 20psi and 18* timing then makes 400kw on 25psi and only 14* the same force is still pushing down on the Pistons as it's making the same power so then the same force is pushing up on the head trying to lift it. Obviously there is more to cylinder pressure like cam design, C.R and other stuff aswell.
