I did this last week on my LS3 and I am very happy with the results.

elcapitan1110 · 08-05-2010, 08:07 AM

I took the fuses out of my ls3 last night, and will see the results later today. I have a 350 mile road trip ahead of me, so I am really looking forward to (hopefully) some increased performance. I will let everyone know how mine came out.

So just so I get this straight, those of us that only can get 91 octane are screwed here right?

No, you should be fine. You should still try a fuse pull though, it can't hurt. The car could have had 87 from the dealer/factory or a bad tank of gas. That will change the settings. It takes two seconds

I tried it. Left them out for 3hrs. Didn't notice a difference.

i know i'm a little late on this thread, but, if pulling the #5 and #20 fuses effectively "resets" the fuel trim tables, would a dash hawk be able to do the same thing? I've heard that the product was able to do that. Would this essentially be the same thing?

Doesn't anyone else think this is a serious problem that should be taken care of.
My 2004 gmc Denali will self correct. In fact the computer will correct the octane table if you put 5 or more gal of gas in.

GM only just recently acknowledged this as a problem. I'm not entirely clear on the technical aspects of it, but I'm sure they will eventually diagnose the cause and fix it.

Custom tunes adjust the timing, the air fuel ratio and with automatic the shift points can be adjusted.
The computer has high and low octane table, which is selected based on knock sensor to protect engine, low table loss is about 20 HP, if you don't feel a difference you were probably on high octane table, high to low was like night and day in my car, as I believe it was with PQ and Scott.
If you don't believe this, fine never pull your fuses, you'll never know, only took 1 hour with mine, couldn't wait any longer to find out if it worked, it did.
Tuners can copy high octane table to low octane table and cure the problem, but then what happens if you get bad gas and knock sensor can not send you to low octane table to protect engine, I'll just pull the fuses after I get better gas, limping along without 20 HP for a tank or two.
some cars run 87 and have no problems, they modded with CAI, headers and exhaust and got much improved HP so loss of some HP due to low octane is OK, and gas is 20 to 30 cents cheaper.
Bottom line computer runs engine, computer protects engine, computer not smart enough to reset to high octane table, probably to protect GM from warrenty claims from us dumb consumers.
PULL your FUSES or just buy the V6 and save $5000 retail, and get same performance.

Someone said in the long thread that the late model builds were self-correcting... is there anyway to confirm that?

This was incorrect information. As of right now this is still a problem for ALL builds. At least this is what PQ has found out.

The V6 though admirable, isn't in the same performance league with a LS platformed power plant................just my .02
