yet another ls swap

[wilber1978]

hey gang,
been lurking for a while as a guest and decided to join and be a bit more active.
current project is a 56 pickup with L98, running standalone ls1 loom and cable dual throttle body's. custom water to air intercooler internal in manifold.
looking at how adaptable the standard P59 ECU is as i have only used aftermarket ecu's in the past for this type of swap.
looking forward to picking brains.
cheers Dave

Is the L98 58x crank trigger and 4x cam trigger?

not 100% sure? it was running in car before i got it as salvaged vehicle. he had fitted the 6.0lt block and 5.7 accessories. so could have changed the tone wheels or re programmed? need to get a cable to pull the ecu info and see whats programmed. also need to put a new program in that has 2 bar map and remove vats. it also was running the maf. so will have to hunt around for a bin that will get me up and running b4 i do any real tuning.

I'm not familiar with the P59 ECU.

For a LSx engine using the 24x crank trigger and 1x cam trigger the factory LS1b computer (aka 12200411) is well supported by the aftermarket.

For a LSx engine using the 58x crank trigger and 4x cam trigger the factory E38 computer is well supported by the aftermarket.

There is the option to use the Lingenfelter 58x - 24x system: https://www.lingenfelter.com/product/L460065397.html#.XfB9QOhKiM8

If you go with 24x crank / 1x cam triggers, the free LS1 Tuning Software is an option: http://www.gearhead-efi.com/Fuel-Injection/showthread.php?7676-Free-LS1-Tuning-Software
