Why not just look at tunner cat files and copy paste them over. or at least they will be a good reference to copy from and enter manually? I have tunner cats and hp tuners on my home computer so I might do some messing around.

You can do that on the fuel tables, but the spark tables on the LT1 are MAP -vs- RPM and the LS1 is RPM -vs- Grams of air per cylinder. I am going to run my engine on the dyno and see if I can kinda get the spark tables figured out!!!
Unless I was reading something wrong with my cal I have, the LS1 Camaro cal only had approx. 25 degrees of timing in the higher RPM/load range (higher KPA of Vacuum), which doesn't seem right to me, I can see that the LT1 has 30-32 degrees in what I would think is the same spot on the chart!!!

As far as the firing order being off are you just re pinning that or doing it in efi live. I have not found the tables to do it hp tuners. I am thinking though at this point i could just get a cam with the ls1 firing order when i make the switch and not have to re pin or worry about computer issues.

without the cam you have to repin the harness either way..

look for injector bank assignment. this is what tells your pcm what side of the motor the fuel is being injected to. without this closed loop may suffer as it would be adding fuel to the wrong bank on switched cylinders.

Thank you i appreciate the help. But I was asking about hptuners because that is what i have. I dont think hp tuners has those tables?? Now what your doing with efi live is just re arranging the injector assignment so the pcm will see them on the right bank but it still does not correct the firing order of the injectors or spark??

the pcm is hard wired that the ouputs fire in the order that they fire in.. you have to wire accordigly. the reason for this table is to let the pcm know what bank you wired its outputs to..

i also relized that you had hptuners.. i dont thou i have efi live. i was showing you where it was in efilive in hopes that it was similar in hptuners..

i guess if someone had both efi live and hp tuners they could change those settings using efi live, write them to the pcm and then read the pcm with hp tuners.. only problem is that any custom os may erase these settings.. and you would waste 2 vins...

like i said eariler in this thread i would reccomend efi live if you havent allready purchased your tuning package..

if you allready have hp tuners they may be able to make these changes for you. i have read they will swap 4l80e tranny segments for users. (in efi live the user can do this)

I got a few questions, I have been watching this thread and the other one very closely.

Getting the crank position from the cam is easy...from a math standpoint. The cam is turning 1/2 as fast as the crank, So its cam signal times 2 for crank position right? Or divide by 2, hell I cant remember.


Heres the rub I see, If you degree a cam, advance a cam, retard a cam, aftermarket crank that is NOT indexed. Natural cam chain and gear wear. What happens on decel with a worn chain? How do you KNOW where the crank timing is? I mean REALLY know? Is there a way to "synch" it when you get all the cam degreeing done? Does it matter?

Hey I am no Guru, Im just askin'.

Has this gone completely kaput?

I wanted a cheaper option than the EFI connection, if possible.
