data logging, now looking good!

Can you try rev it out to 7k in 3rd and 4th? That should see the maximum maf figures. Should also show max inlet temps.

for some reason its cutting back the power at above 4.5k, not sure why this is.

[paultownsend]

Thanks for that. At maximum maf reading your cyl3 is seriously retarding. It doesn't seen temp based

[jamie16v]

cyl 3 is normally most restricted to exhaust manifold flow i think 
also i have the standard cat still currently fitted.. perhaps contributing factors? i don`t know 

[paultownsend]

One last question. What's the difference between knock and retard?

[jamie16v]

knock happens when the ignition is too advanced (sparking too early in the stroke) or fuel too lean for running conditions, also known as detonation or is det a worse form?..lol
retarding the timeing brings the spark closer to TDC (sparks later in the stroke).

Is that WOT from 2640rpm?

Here's a look at mine to see how they compare (air mass readings look low due to VR6 MAF)

[jamie16v]

foot was planted till end of log mate.
also the inlet temps look ok in the first log but they did rise a bit later on, the toyosports fmic kit is suffering a bit of heat soak i think  although this doesnt seem to be the cause of knock or cutting back
i`m under the impression it may be the turbo and actuator not agreeing with the old map?

[Wazzzer]

log the same as mine and see what happens

also have a look at your throttle angle and see what it's reading (without the engine running though lol)

[jamie16v]

i did have a look at that before mate, wot was about 83 or 89* cant remember exactly. i know yours was jamming early wasnt it?

[Wazzzer]

yeah, had to file away the stop to get it to 89
