Hi All,
first time poster here so be nice
I have a LS1/4L60E out of a 2003 VY Holden SV8, ran well in car but this combo has been used into older vehicle.
Engine was rebuilt, rings bearings , etc and VCM710 , springs , pump etc. Auto also has been rebuilt.
Had the ecu loaded with a tune file to suite the cam to get it running, trailed to the the tuner (5hours away for final tune). Car drives and runs great, only issue it idles when it wants to. i had chinese T/B on it when it was tuned and the tuner thought this was the issue (had a 4.5mm hole drilled in it as well) , replaced with a edelbrock 90mm tb still the same issue (seems to drive better though). i have the throttle cable wound up to get it to idle and to make the car driveable. The idle motor seem to work when it wants to (has a mind of its own). When it was being tuned you can manual open the IAC. When starting the vehicle you need to use the accelerator to get it running and then hold it slightly, its becoming a real pain especially when pulling up to a set of lights and trying to keep it idling.
ive attached the tune file and a log file. i will be purchasing the hp tuners mpvi2 when VCM areopen next week as i have a couple of LS based vehicles and it will come in handy
