My car is a 1995 Z28 Camaro. The engine is the LT1 with OBD1 using the OBDII style port. I'm trying to learn more about tuning the car. I have Tunercat, Scan 94/95, and eehack and trimalyzer by Steveo.

I've been modifying the tune using the tools in Trimalyzer. Today I datalogged using eehack. When I run the analysis I get readings showing fuel is being added in the main operating range e.g. idle up to about 3,000 rpm. it looks like the ecm is consistently adding fuel because the engine is running lean. At least that's my understanding.

Here's a jpg of the results. My question is what do I need to do to the tune if anything or is this pretty normal?

Here's briefly what I've done to the engine. Lloyd Elliot's LE2 head work, ported manifold, custom grind Comp Cam spec'd by Lloyd, ported MAF ends, #30 Ford Bosch fuel injectors, Pacesetter Long tubes into a 3" Borla exhaust no cat. Tune by PCMforLess with adjustments by me using Trimalyzer. Stock ignition e.g. Optispark.

I've posted all about the project on Z28.com as KYWes.
