I've been doing more digging through the maps on these later model ECUs, clearing up what the Japanese tuning mobs got wrong 8)

I've got launch control ready for the R34 skyline (with antilag retard upto -5 degrees). The injection adjustment stuff needs to be reworked

Matt would be keen to get an hour of your time to go over that tune and identify the issues so when I take it to someone else they know what they are looking for

Could do a remote log in to the laptop from oz

Would fly you over here to tune it but $$$ would be crazy :P

Shouldn't be necessary to do that - plus I just dont have free time!

Take the attached tune to use as a starting point. Adjust K Const until your trims are close to 0% and that should be a good base to work from. Load scalers may need some adjustment depending on coverage of the fuel/timing maps

Usually just need minor adjustment to the fuel map and then tune your timing map
