Well I must admit I didn’t think it would come to this but here I am, hav rebuilt a LQ9 stoke stroke 9.5:1 Comp, 238/242 114 cam, 90mm TB and edelbrock pro glo intake.
I have the engine on a stand with a stand alone loom so I can get some sort of base while I wait for the rest of the car to be finished. But running out of ideas to get a base VE set up. Started with a factory 5.7 tune added 10% across the board, was running but was lean enough it was popping out the exhaust. Added some more but AFR still lean so grabbed a 6l tune from a HSV well no better no popping but AFR gauge still off the charts lean. Added more across the board up around 90 in the idle areas still no AFR reading. Try give it a rev just dies. Decided I would make it a flat 80 across the board see what would happen still the same.
Is there an equation I can use to give me a base or does someone have a similar setup that I can have a look at a VE table that works. Was planning on getting it idling few revs see where it’s at using auto ve and adjust from there. Bit hard without a usfull AFR reading.
Thanks.
