Hi everyone, it has been a while since I have been on the forum but I am trying to be a little bit proactive as I am half way through an engine build.
I am looking to use a GMPP tune file to use or assist me in developing a base tune to suit this engine build.
Existing details:
HSV Clubsport 6.0L M6
W427 OTR
Hurricane headers 1 7/8"
2 x 100 cpsi cats
2 x 3" right through with resonators only at the rear
New build:
LS3 heads minus 0.030" (11:1 cr)
L76 intake manifold
Camshaft 0.525/0.525 224/236 110LSA
1.7:1 Yella Terra shaft roller rockers
160o F thermostat
ATI super damper 25% UD Accessories 10% UD A/C
SLP 55001 oil pump
I figure a lot of the LS376/525 tables will be rather handy as at least a starting point should this mofo decide to not play too nice in the beginning with my existing tune which was dialed in perfectly.
Not too sure what else I can do in a proactive approach, just trying to be prepared and so I am open to any advice you can provide.
In fact, many of you may have already experienced this but when I removed the existing heads @ just under 90,000 km's I found carbon deposits in the combustion chambers covering approx 10% area and a fine layer taking up 80% piston crown area. Plug color and everything else was also indicative of a perfect tune (this engine was tuned about 5000 kms ago now) which is something you rarely see when you pull an engine down that hasn't been given the attention with regard to tuning as many of this forums' members do. I would also like to take the opportunity to again thank the guys on here that often assist members with dramas that must seem repetitive and simple but these responses are tirelessly repeated and make EFI Live such an awesome product.
Thanks in advance
