Hey guys,
Per Razor's advice b/c of too many things to mess with... since it wasn't tuned yet....... I bought a TT chip to try instead of my extender/translator setup for my LS1 MAF meter. Current mods in my sig. I put the factory MAF meter.. and maf hose... and installed a 14" K&N on the end of the MAF meter. I then installed the TT chip.. in my spare ECM.. and fired it up.... it idled good... sounded fine... so I took her out for a test drive..... ran about 10 minutes.. before I made the first run... had some knock... pulled over... and examined the log.... incresed the "blue knob" from about 50% to about 80%.... made another short blast... uphill... to about 80 mph..... pulled over and looked at the log.... knock looked good.... had to run to the store.... on the way home... I stopped on a long straightaway... cut alky back to about 60%... made a blast.... knock looked good...
All runs appear rich to me.... but I need to cut the boost up. My boost was set on about 20-21 psi with the big MAF pipe and LS1 MAF meter.... but only was 17 psi with the stock MAF meter....I think I will have enough fuel...when I get the boost up...I am not going to mess with the fuel... until I bump the boost up to at least 22-23 psi...
All runs felt lazy to me... but that is likely to be b/c of the boost only at 17 psi.... the last time I drove it... the boost was 20 psi +..... probably most of the lazyness I am feeling now... plus it is fat....
Would you guru's look at my logs and tell me if you see anything I might be missing....
All three runs... were on street tires... so you will see on the logs... that I couldn't floor it until about 30 mph or so.
I also put a word file in there to describe the conditions of each of the three runs....
