The car is not going to be under hard acceleration for long periods of time though (ie no track days etc)
Would you recommend I run a fairly low Timing/boost setting without a uprated FMIC?

I can't really say what timing level would be safe. You would have to log the car. Just because the op got a lot of timing pull on his car doesn't mean you will and also you may not be able to run timing as high either.

Every car reacts differently but the general rule of thumb is you won't be able to have high timing without an updated intercooler or water meth kit.

The best advice I can give you is start off low on boost and timing ( B7 T4 ) and then gradually increase one level at a time until you can't go any further. If your unsure log the car and pm me I'll give you my email and I'll have a look at them for you.

Cheers mate.  :happy2: Will be doing some logs and stick them up here for you to have a butchers. I realise that no 2 cars are the same (especially when Revo settings are involved), so like you say, it's hard to say. But starting on the lower boost and timing settings seems like the way to go for starters..  :happy2:

Carl, i run 976 and may be going decat. I assume then i will be able to raise the fuel to 7 which will lean it out more due to the lack of cat...yes?

vRS Carl:
Not necessarily no.

You have to log the car.

Just because you have a De-Cat doesn't mean you can lean out the fuel. Doing so may mean you get higher timing pull.

If you lean out the Fuel the car gets hotter, think more oxygen means bigger bang which in turn means more heat. This could mean that your car runs fine on B9 T7 F6 (i can do the same) however if you lean out the fuel to 7 you start to get dangerous timing pull levels. I have some logs going from 976 to 977. When on 976 i would get timing pull of around -3.8 on all cylinders. When i leaned it out to 7 i then got timing pull of -6.4 across 3 cylinders and 7.2 on the other.

You may find that you could run 877. BUT you need to log the car.

I really can't see what the obsession is of increasing the BTF. The difference in power is neglible. I have logs of my car on 877 and then on 976. I gained 2bhp and 5lb/ft so i didnt see the point of running the settings so high. I have done hundreds of logs on my car (317 last time i counted) and found that on 857 my car runs smooth and has no timing pull. On those settings i am only 3 bhp and 7lb/ft less than on 976. Something you are never going to notice on the road. So unless you really are chasing no.s then i would say if you car is running fine on 976 then leave it.

As the chinese say - "Dont fix something that's not broken"

Hopefully that helps :happy2:

Some heavy techie gumph here... what's timing pull?

markc:
The ECU will adjust from the Knock Sensor to 'pull back' the timing.
