i always go 11.5 after hitting full boost as a proper safety measure.. see some loss in kw but rather play it on the safe side

factory usually stays 11.0/11.1 mostly

how do u get afr to get inline with boost?

the tables are load based from wat i see....or m i missing something 8)

eh, you missed something, you tune through out the map, not just at WOT.

Maps are generally load based so at curtain manifold pressures you set the desired fueling, timing etc etc.

[Pappu1]

wait i dont follow.. are u saying that there is a separate map that has manifold pressure vs desired afr and timing?

or u saying that infer the manifold pressure based on load zones?

[todagt]

In most cases in regards to aftermarket ECU tuning the Manifold pressure is the load axis in the map.

As load increases (boost) it goes into another row in the MAP table so in the zones in the table you set the desired Fuel ratio in regards to load/rpm. For instance there is no way you would want to have 11.5:1 at just off vacuum. Picture cruising up the bombays in 5th with around 3 psi in the intake. It is just a waste of fuel. Typically 13.8:1 is lean best torque at 0psi, so anywhere between 13:1 and 13.8 is the best place to be and you gradually richen as the load increases higher.

BTW, i think this is going a bit too far off topic now.

lol.. yea off topic... maybe will open a new ecu tuning topic etc.. yea good explanations i know what u mean now.. i do the same too..lol.. just was not sure when u had put it in the original post..

96 RSB, forged 2.0 with a TD05 18g, suspect that the internal gate isnt fully closing so hence the late spool.

[Scoobydoo]

PhatRS: gained two places on the chart

[PhatRS]

Hopefully gain a couple more KWs when I fix this leak too

That graph climb's wicked from 3500-4700 rpm

you should be in the pilots seat ;D

[caspros]

Oh, right, I thought it was done on 4th August, not 4th July 2010.

oh yes!! baha.. in dire need of coffee this morning!!

[pedro]

Thats an awsome result funky.

you will be able to short shift a little at around 6000 and most other drivers will have to ring the necks out of there engines to get past you.

could be that you get slipstreamed a fair bit...thats if they can latch on to your missile exiting corners.

congratulations to all invovled..

Haha nah, my reading went lower the higher the PSI went, I think peak was on about 18. What it needs is an exhaust upgrade (acquired, but not put on yet) and an ECU reflash (planned for a couple months time).
