How'd it fire with the fresh plugs? 7:1 idle would kill a set of plugs in 5 minutes then you'd get 20:1 after that with poor firing. Whats your VE at idle?

Re: vr v8 turbo base tune
the idle ve is the same. In the log I was going into the idle ve and adjusting it as well as turning it on an off. Setting the idle ve to 40 gave the best idle any higher an it wanted to die. Still need to change the plugs, but I can't get the front 2 out with out making some kind of custom tool

Re: vr v8 turbo base tune
Are you logging with that 1 bar adx you linked above you want the 2 bar one if using 2 bar map
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem
Re: vr v8 turbo base tune
What do you mean idle VE? Closed throttle VE wont be in effect unless you enable it via the flag.
30-40 %VE would be where this will want to be. But good plugs will be a must. Get set up ready in RT to make any quick adjustments once you first fire with the new plugs save killing them to quick. How much timing you running at idle?

Re: vr v8 turbo base tune
I was using the 2bar adx but it wouldn't let me connect with the aldl in tunerpro so I changed back to the 1bar adx. I was assuming with the 2bar map selected it would still be ok? And yeah Dylan closed throttle ve is what I was playing with in real time to see the affects quick changes to the idle ve would make in both the closed throttle and main ve. I quickly found that setting the closed throttle ve and adjusting upto 1000rpm to 40 gave the best idle

Re: vr v8 turbo base tune
At idle around 21deg
Re: vr v8 turbo base tune
Bump that up to 28. Match up the running table to in the idle kpa range.

Best to ensure your base timing is correct to first if not done already.
