Zr1 file is where you should start with .
I seen this before any idea why?
Can u describe the starting issue more.? Does it crank too long?
Here is a link

You should use the ID data from their web site no need to use any spread sheet ...
Have physically deleted the VVT? Mean swap parts? ... When u ad so much fuel and there are no changes? I suspect u have a leak some where ?
Which map table ?
That's correct ...ifHe starting from complete new tune ...if he is running maf tune ... His SD Coffients are stock and he have to re do them.... Where my point is he can do some data logging using...
If u upgrade to 2.5 Bar u don't need the EQ-VE Program
Then u can set up ur VE tables in the scanner and plot ur GMVE values...if u have nice loaded dyno then u can fill almost the whole tables...
If want to do it right it need to be scaled ....
Or u can use double stoich and cut the IFR in half ... ( not sure if this will work in ur 80lbs injector )
If u have good MAF tune ... U still can work from there to build ur VE table...
Hi agree with u about the fuel,here ..check ur inbox pm sent
That's very impressive numbers for stock ls7 .. Good job
Thanks for shearing this ...
Do some logging and see how the car runs... Most probably you won't change alot
Couple of pointers going from aftermarket camshaft to a stock one ...
Idle fuel...idle spark ...idle AFM ..WOT + MID rang spark ..misfire tables ( depend what cam was in there before) ..
I think he meant he put the stock cam back in the car ,,,,
To OP ..
IT'S simple retune .. Either work on what you have .. (,wish I what I would do if the old tune was good)
Or work from...
Don't think so ! Didn't see any parameter that relate to that ,,,
Upgrade to 2.5 bar OS then you will have the good old VE back
Flat battery!? Or it keep cranking with no start?
Thanks Dave and Chris , new open possibilities now .
On loaded dyno you simulate a crusing condtion, with load , see how much tourqe ur getting for each rpm range , then increase ur timing to see if u gain much ,,,doing that you will find ur Min spark...
agree to what he said ... plus due to unknown cam you have .. sometimes need to play with the timing abit til you find sweet spot ..couple of degree above stock value otherwise it will keep hunting...
