Hello from Australia.
I'm new to the forum and looking for some help to set up my initial tune.
I have a 2002 Holden Commodore SS Ute. Modifications and specs listed below.
5.7 LS1
LS6 Intake
BTR Cam kit stage 3 - 231/244 dur. 631/615 lift. 12.5 lsa
Mafless OTR intake
Stock reco 241 heads
Trunnion upgrade
Dual roller chain and gears
Tri Y headers, 100cel metal cats and dual 2.5" exhaust fitted with a Bosch Lambda sensor LSU 4.9
Rebuilt and improved 4L60E
9.5" custom built 3,800rpm lockup converter
3.9 gears
Upgrade Walbro pump
38lb genuine Bosch injectors
New genuine GM coils, leads and plugs
I'm a qualified mechanic so I have a reasonable understanding of the tuning requirements however at 60 years of age I'm a complete novice when it comes to custom EFI tuning. I don't intend to use a dyno as I have no real interest in before and after HP numbers so my tuning will be road based.
I have joined the HP Academy online learning and have invested in the HP tuner with pro link.
I'm in the middle of everything at the moment and expect to have the car back on the road in 6 - 8 weeks. I'm looking for a base mafless tune that I can load in that will let me start and run he engine to run-in the cam and get the car moving, from there I'll log and make small adjustments as required.
Apologies for the long 1st post, hope somebody can help.
