/\ wow - really ? how much powa ?
how do your EGTs look ?
I spoke to a old school rotary tuner here about timing and he thought i was running way too advanced . How come the Renesis can take it ?

Around here, 1° or 2° more at the torque peak than what he is running will ping.
Its all a balancing act. There is more power to be had from 1 AFR point leaner than 1° of timing.
If the EGTs are good, I'd only bump the <175% up a good margin. That is where this timing table is lacking.
A whole bunch of resolution is being wasted on the 150% - 200% range.
Wasting half of the table's resolution from 100% - 200% isn't productive. I do all of that in 4 columns and save the rest for drivability and transition.

On good fuel.

Thanks for the input

How does the ECU handle settings between tuning points if you lower the resolution for the 100-200 load areas? Does it stay on the previous setting until it reaches the next setting point or will it scale between them depending on which it is closer to?

Would it be possible for someone to please post their Turbo timing maps up in excel format.
Also I'm not to excel savvy so would it be asking to much if someone could work on a Timing worksheet with Leading, Trailing and a Split table, that allows to adjust the leading & trailing by chaning the split values? THIS WOULD BE ABSOLUTELY GREAT!

/\ t 70 -greddy e-mangle - no tune !!!!! oh dear
If you can't alter the e-mangle settings yourself all you can do is put the stock injectors back in and stay out of boost till you get a tune .
what posessed you to put that monster turbo in there - any pics ?

Same size as the Esmeril kit pretty much.
Here this is the T-70 turbo from Esmeril kit
