Ok, here goes;
My '89 IROC L98 is runnin way lean (white, flaky plugs). I'm goin to the strip tommorrow, and need to add fuel to richen up the air/fuel ratio to a reasonable spot.

Car: Stock (but rebuilt) L98, no egr, no smog. I am runnin a Crane 2023 compucam, shorty headers, 6deg base timing, reduced max timing to 42deg in 3D spark table (TunerproRT w/Moates), and have a Mallory AFPR set to 45-46psi at idle.

My question is a general one:
What 2D tables (in TunerproRT) can i raise to uniformely increase the amount of fuel the engine gets?
I'm thinking the "Injector Pulse Width Correction vs Battery Voltage" or the "Power Enrichment vs Temp" tables...

I just need a 'pretty close', safe tune that i can fiddle with before i go to the strip, but dont have an A/F ratio meter or real-time data logging at the moment. Wanna have a safe tune and get the plugs tan, not white basically.

I realise the mixture will not be optimised with a quick fix, but are looking for a safe improvement to reduce the chance of engine damage/detonation.

Thanks in Advance!

 

They all going to have a hangover for the next 12 hours.

I'm only new to this but Inj Pulse Width Correction vs Battery Voltage only adjusts for varing battery voltages and the PE vs Temp only works under WOT as in power enrichment; would not affect cruise fueling.
Possibly adjust your injector size in the constants (FI size @40psi ) as that affects fuel across the whole range.

 

Yeah i was thinking the same thing about the first two.
Im unsure about which way to adjust the injector size - up or down.
Hmmm..

Going to Wicked Wednesdays at WSID tomorrow night so i wanna be safe with the tune.
What did it cost in shipping to get your HSR from the US? Im lookin' at one..

 

Smaller size in constant = richer.
Have to check what post cost was.USPS only do Air mail to Oz now so more $$$ but cheaper than the one for 4K on Oz eBay.

If you are serious about tuning should come to V8 Owners WSID track day in March.Beats 4 runs on a Wed night .
As many runs as you can fit in for $200

Thanks for the info bout injectors.

Sounds good, thanks for the heads up bout v8 owners day!
