Here you go mate,

Still haven't found a base map that would be any good for yours but i do have some launch settings



Other setups i have seen run a low as 1deg advance and have a lower rev limit. I found this worked well but was very harsh, so backed it off to 3deg and have a slightly higher rev limit due to the sticky tyres i was running. On normal road tyres i would go for a lower rev limit, or retard the timing less, or pull fewer sparks. This will limit the boost made on launch but also help with traction.

Launch control is good fun

My Input/on value may be different to yours too depending upon which input you are using for launch.

Happy pops and bangs

I would set the TPS threshold higher then 20% otherwise if you accidentaly rest your foot on the clutch at high RPM it will engage when you dont want it to, mines at 90% for example.

Yeah all good! Running about a 14psi at the moment (dont think the .48/60 will flow much more TBH), feels about as quick as my CVH did at 30psi (around 270bhp) but have literally only spent 45mins mapping to just make sure it's safe!
Much more responsive and so much quieter than the CVH too, engine itself that is not the exhuast note as that sounds exactly as it did before!

Sweeet sounds like its all going well Karlos! Have a play with the TPS value Rick, I kept it quite low as you can use the throttle to adjust severity, with the throttle backed off mine was making 5psi boost, planted it made over 10 but it did sound very violent lol!

Only thing I dont like is it doesnt pop/bang when launching or flat shifting like the CVH did, I get the odd one but nothing like it used to! lol
Not had a chance to play with the settings yet though!
