I had to back off for knock across the entire RPM range. Reduce octane requirements substantially. We only have 91 octane in NW AR, and we are only at 1,000 feet altitude max, so not high enough altitude to Thanks as always for your input gentlemen! I have attached my current tune and the 04 Z06 OEM file as well. My LS1 is just getting to the point where I dont think it can really benefit using OEM LS1 tables when it comes to max torque timing, IAT & ECT spark tables when GM puts way more R&D into the vette LS6 and LS2 platforms which mirror my engine closer. I have also been looking over 2005 LS2 vette timing advance tables just to get a basic idea of what higher compression LS engines run for timing. This makes me wonder if I shouldnt try to mirror the z06 max torque timing table instead of the f-body 2002 stock file.Īny thoughts? Any other tables I should consider? My question is this: since my engine set-up has changed since my original tune (basically head e #1 post for mods) and from I have researched my engine now being a higher compression (11:1) should require less timing for peak torque. I have been since than comparing some of these tables to a 2004 Z06 stock file. My original tuner used a 2002 f-body M6 tune for his baseline template and from what I can see in my tune he did not alter the max torque timing table, IAT spark and ECT spark tables. I do have a new concern regarding the max torque timing table. I have fine tuned my timing table a little more since my last post. I just purchased Master EFI Tuner-GM EFI today and look forward to what that has for material. I use 91 octane (highest up here in Mt 3400ft).

I have been just researching lately and noticed some threads on high compression engines needing less timing. I didnt log any knock during OL and CL logs, AFR is 12.5 at torque peak to 12.7 near redline. I have just finished tuning both my VE and MAF in OL.
