Question E85 LS1 Turbo startup tune issue

Hi,

I'm new to HP tuners and I'm currently trying to setup a base startup tune for my single turbo E85 LS1

LS1 has the following parts

2BAR map

Maff disabled

1000cc injectors - injector data has been setup as per instruction's with injectors.

rising rate FPR

VCM264 cam specs are:-
287 intake 278 exhaust
232 intake 226 exhaust duration @ .050"
.591" intake .598" exhaust lift
lobe sep 114"
Stoich 9.71 added 15% more fuel to VE table

will attach map file and a log file. Log file won't be much tho...

I'm unsure if the 15% more fuel is causing issues or more adjustment needed to suit cam?

any help or pointers would be much appreciated.

Default

I would go up to about 30% -35%. Also E85 needs a lot of cold start fuel.
