Road tunning

Hi all im about to start road tunning my car it was tunned by a large shop in Brisbane some years back, however still needs a lot of work in my opinion

Just a quick question I have data logged afew times (Haltech ps2000) and AFR are all over the place and id rather not left foot brake at high rpm just wanted to know is there a time in MS when data logging that im safest on make a (small) change im not worried about low rpm/cruise just the higher rpm sells

also has anyone else tunned a RB30/25 that wants to share any advise? lol

I have uploaded my base fuel map from when I got the car back if it helps I have made afew changes since this,

You don't specifically need to use the left foot braking technique at high rpm, at least not at high load. These areas would be tuned using a normal full throttle pull as discussed in the course and then checking the logged data. If you're logging AFR then this should be all you need to get the fuel table trimmed as required.

I'm not sure I properly understand your question though? When you're making changes to the fuel table you can use the correction equation - Measured AFR / Desired AFR = correction, to apply a change to the numbers in your efficiency table and correct any error you have in AFR. If you have quite large errors, you could make small changes of 2-3% at a time so you can log and see the results of your changes. This will help you creep up on the correct AFR.
