Im currently trying to base tune a 2006 5.3 LM7 With Mods engine SWAP thats going in a 97 Camaro LT1/T56 car. This is all for a tune prior to first startup. New piston rings and cam have to break in.
Swap:
The LT1 is gone the 2006 LM7 5.3 is built and in the car and mated to the LT1 T56 (swapped bellhousing and midplate and input shaft).
I put the 5.3 LM7 on an 1999 Camaro LS K member.
It has a 2000 Camaro LS Engine Harness (C210, C220, C230, C100, C101, C105 repinned for the LT1 Body Harness ).
Junkyard 2000 Silverado 1500 5.3/A4 ECU P01, has matching 09354896 as came with a stock 2000 Camaro 5.7/M6 car also P01
All new 2000 Camaro LS sensors, accessories, and oil pan (except for 98 Camaro coolant temp sensor (3wire) to function analog dash gauge too).

Ok most of that info might be helpful and some of it might not I dont have much experience with HP tuners but Im learning, ive watched alot of the The Tuning Schools and some of Goat Rope Garages Youtube Vids and taken alot of notes. So here come my questions Ive taken a 2000 Camaro 5.7/M6 Stock tune and Compared it to a 2000 Silverado 5.3/A4 Stock tune. I firstly disbaled CAGs, TCS, the Air Pump, Vats, rear O2s, Cats, Evap System, and EGR.
My questions is what should i modify to make this modded 5.3 run in this 2000 Camaro 5.7/M6 Stock Tune? Im staying away from Spark for a bit, more concerned with MAF/MAP and Fuel tuning. Ive adjusted what i think it would take for a stock 5.3 to run in the camaro 5.7 tune as follows.
So i went through and looked at all the comparisons that changed between the two in the Fuel tab, under Injector Control I read that flow rate vs kpa is pretty important the 5.3 tune runs a flat setting where the camaro runs a variable setting for some reason i think the camaro setting would be better but i entered the 5.3 flat setting of 24.8 should i stick with it or revert back to the camaro setting to start with and modify from there as the base tune? Under cranking fuel I also added the 5.3s prime runtime and 3 lower pulse mass settings didnt think it would matter much. Last on the fuel tab the i set the LTFT enable temp to the 5.3s of 131* shouldnt hurt to enable sooner right?
In Airflow its cable throttle so thats disabled on the camaro tune already, Under Dynamic- Dynamic Airflow and Steady State i chose to stick with the camaro tune there were a few that dealt with the MAP that the 5.3 differed but i didnt swap them over to the 5.3 tune settings, let me know if this is concerning. Under General all i changed was the Main and Secondary VE tables, the Main VE the 5.3 has a stiff shelf at lower rpms with high MAP pressure as the MAP pressure grows im wondering if this is due to the truck intake it came with. I left the gradual Camaro table in there above 4400rpms and modified and smoothed the 5.3 tune below that figured the 5.3 tune below 4400 would be better and then slightly higher 5.7 tune above 4400 would help with the bigger cam in the 5.3. On the secondary i did the same swap to the 5.3 VE tables richness below 4400rpms again and smoothed out the shelf it had as it was concerning me. It could be too rich between 35-85MAP and 400-3600RPMs.
In Idle, under Airflow and Startup I changed the underspeed time to less didnt think it would hurt, and then in General the IAC Steps vs Area and IAC Park Position options on the top left to the 5.3 tune settings. Then Under RPM most of Proportional was changed, and the two Allow RPMs on Derivative.
So this is what i did in my thinkin of making the 5.3 run in a 2000 Camaro M6 tune and application. So With the Bigger cam ill need to add more fuel but as for a start do you think my current tune is adequate or too rich or too lean in spots? With the LS6 intake and injectors should i lower my injector pulse width to like .450 or should i just grab the specs of a 2004 Corvette and swap over the injector and intake related tune settings? With the motor mounts clutch and valvetrain components am i gonna need to worry about fake knock signals when i add timing in the future? I still have a few more videos to watch and threads to read but where is the best place to start with my setup for fuel tuning? I have a AEM Wideband 30-0300 i plan on installing in one of the rear o2 bungs to help with data logging. Basically im looking for tips and a look over to make sure im not gonna hurt anything before i start up the beast, i havent found any real info on tuning for a 5.3 swap into a cable driven Camaro with a M6 with an intake and cam. Any help is appreciated very much.
